         The Technology Enhancement Programme (TEP) have been
         associated with ICHF and the D&T show over many years
         and are pleased to celebrate the show’s 26th anniversary.
         Visitors to this year’s NEC show should leave themselves
         plenty of time to visit our stand. TEP will be featuring the
         breadth of support and activities available. Each day will
         include ‘on-stand’ clinics for teachers and led by teachers
         on CADCAM, Robotics, Desktop Manufacture, Materials
         Technologies, Systems and Control and Electronics.

         This year TEP feature in the NEC seminar programme with a
         particular emphasis on Desktop Manufacturing:

         In this issue of News and Views, we can announce a record number
         of new high-technology materials and components – all with
         tremendous potential for designing and making.                                                                                Rare earth

         Ferocious Magnets
         Rare earth magnets made from exotic materials such as samarium, boron and neodymium are the most powerful ever
         made. They have quietly revolutionised product design by giving us new types of electric motor, loudspeakers, micro-
         stereo headphones, magnetic drive systems – and many more. Electric toys such as aircraft and helicopters only exist
         because of the high power to weight ratio achieved in motors using these magnets.
         TEP has now added even more powerful and larger magnets to the range already on offer. These are described in
         commercial circles as ‘ferocious’ because of their fantastic pulling and repulsion characteristics. Potential uses in
         design and technology range from the design of small magnetic products such as fasteners to the design and actual
         making of loudspeakers – previously beyond the reach of pupils and students.
                                                                                                                                                                   DIY Loudspeaker using
         Tim Hunkin, the well known automatist and TV presenter, demonstrated a DIY loudspeaker by taping a flat coil of                                              a rare earth magnet
         copper wire on a bag and placing a magnet in the centre. When energised, the coil moved about the magnet and
         produced a weak sound. If the ordinary magnet is replaced by a rare earth type, the volume goes up by an
         order of magnitude, and practically any flat surface from a cornflakes box to a table top can be turned into
         a surprisingly good quality loudspeaker.
         To make such a loudspeaker, you simply need to wind a coil of copper wire around a ‘C’ size battery (or
         equivalent) and then glue or tape this to the surface. Bring the magnet close to the centre of the coil and, as if by
         magic, the sound begins! In a more permanent set-up, the magnet can be placed on a small foam pad in the centre
         of the coil.
         A new TEP starter pack provides magnets, copper wire and a small booklet describing different ways of making flat
         loudspeakers (and the factors governing performance). Most young people use sound systems of some kind, and this
         provides added motivation for project work ranging from graphics to engineering in metals. All of the magnets now
         available can be used in loudspeaker design work, but, generally speaking, the larger the magnet, the great the
         The new range of ferocious magnets includes a number of miniature sizes that professional jewellers are now
         incorporating in their work as a substitute for traditional fastenings on brooches and garments.

         Robo-tyres and Rover tracks
         TR has now invested in an injection moulding tool to produce soft durable tracks with a transverse tread. At the same
         time, we have taken the opportunity to create two pneumatic-style rubber tyres of the type used on expensive radio
         controlled cars. The new TEP tyres are of the same quality, but a fraction of the cost. The
         aggressive-looking spikes are popular for their looks but also functional because the
         turning/rolling resistance is virtually zero. The spikes enable the tyres to climb easily
         over obstacles.
         Both tyres allow the creation of flanged wheel centres or two-part wheels. Because                                                                              Tyres and Tracks
         the tyres have a deep recess on each side, the latter is easily achieved by making a
         ‘wheel’ from two separate disks – one for each side. These can be cut out using a                                                                   Manually make wheel inserts
         lathe, CNC milling machine – or even laser cutter. Alternatively, the inserts can be                                                                  by using a compass cutter
         made manually. A disk of material such as mirror styrene or the new TEP chameleon
                    card for the outer surface completes a very attractive wheel.

                                  Solar Panels
                                        The new solar panel, announced in the main catalogue, is a major new addition to TEP
                                         resources because it is similar to those used in aerospace applications and more
                                         efficient than common ones made from an assembly of fragments. Because of direct
                                        purchasing, it is now also at a lower cost! Unlike other solar panels, it is so efficient it                Solar panel used
                                                                                                                                                    to power a motor
                                      can be usefully energised from a high-intensity torch.
                                                                                                                                                    driven buggy
                                  Apart from direct drive applications under sunlight or concentrated artificial light, the panel
                                can also be used to charge ni-cad batteries or super capacitors – e.g., trickle charging over
                              minutes to delivery useful energy for solar motors or an LED lamp or torch.
                           A new solar power starter pack, designed for both science and design and technology specialists,
                         provides a range of sample components and a booklet containing information,
         investigations and practical applications.

         Super Capacitors
         Super capacitors with a value of 10 Farads - an unbelievable figure just five years ago –were first
         developed for computer back-up applications. They now have a wider currency in products such
         as instantly rechargeable toys (e.g. electric aircraft, micro-cars). To avoid the normal high cost,                                               Super Capacitor
         they are now made to order for TEP - empowering pupils and students to design and make their
         own instantly rechargeable products – torches, buggies etc. The capacitors can be charged from
         a conventional 3-volt battery in just seconds and then deliver useful and sustained bursts of
         energy to motors etc. They can be connected in parallel for high storage capacity.

                                              Transistor project board
                                              In response to the many enquiries about ‘one-component’- electronics, TEP has created a single transistor project
                                              board that enables pupils to learn about transistor switching and apply the cheapest available transistor to a wide
                                                   range of practical uses. The board is supplied unpopulated and needs just a transistor and a choice of other
                                                    components – two or three – depending on application. It is available as a single-board starter pack with
                 Transistor                         explanatory booklet or in class sets. A free introduction pack (with a page from the booklet) is available for
               Project Board                       those able to visit TEP at the NEC.

                                              More low -cost equipment, accessories and products
                                              The tightening of budgets prompted many colleagues to ask us if we could supply power tools etc. at supermarket
                                              prices, the answer was ‘yes’ – and sales have been brisk enough to support the purchase of more items. These include
                                              a replacement for the original hot air gun (useful for thermo-forming plastics), a low-cost laminator, ideal for glazing
                                              graphic product work and plasticizing card design work to give that professional finishing touch.
                                              On the adhesives front, we have introduced a (normally) trade-only spray contact/impact adhesive used
                                              commercially for coachwork, upholstery, display systems etc. It sticks a wide range of materials including stone to
                                              metal! It is an excellent substitute for contact adhesives that are often messy to apply and then difficult to store
                                                 without evaporation and loss. (Note: good ventilation during use remains essential.)
                                                    Also now available is a stick adhesive at what we believe is the lowest price in the UK. Apart from low cost, it
                                                    has the advantage of being PVC based (as opposed to PVE) and is ultra-clean as well as offering high bond
                                                    strength. It can be used on wood as well as card and paper.

                                                   Phone PIC and Chip Machine
A4 Laminator                                      Two major innovations will be demonstrated on the TEP stand at the NEC in November. Both offer
                                               entirely new and easy ways of programming chips. Although TEP’s award-winning Chip Factory continues
                                              to provide our ‘industry standard’ programming facility, the two new systems, offer even cheaper and
                                              simpler programming for beginners. Neither requires a computer: the Chip Machine just needs a PC
                                              keyboard and the Phone PIC simply uses a mobile phone!
                                              Phone PIC
                                              This pioneering system uses any mobile phone for programming. It consists of a small circuit board with a microphone.
                                              You simply hold your mobile near the microphone and enter a programme using the dial-up keypad. The Phone PIC
                                              responds to the acoustic tones (DTMF tones) generated by each key and translates these into program instructions.
                                              In newer mobiles, the numbers pressed appear on the LCD screen, thus visually recording the start of any program
                                              entered. It is even possible to program a PIC at any distance by phoning a third party who then holds the Phone PIC
                                              near their own mobile! ( See Page 9 of this issue!)
                                              The Phone PIC will accommodate existing 18 pin PICs such as 16F84 and 16F627 which are supplied partly
                                              programmed AT NO EXTRA COST. Because the Phone PIC firmware is in the actual PICs used, the system is future
                                              proofed against any possible upgrades an important consideration when buying any PIC programmer. The Phone PIC
                                              is supplied ready to run and features a ZIF (zero insertion force) socket making it very easy to move PICs in and out
                                              without damage.

                                              Chip Machine
                                              Of all the TEP PIC programming systems, this one probably offers the easiest route to programming a chip. The
                                              programmer is a tiny board that accommodates the newer and cheaper 8 pin PIC (12F629). You simply plug the
                                              programmer into a PC keyboard (supplied in the basic starter pack) and use a limited number of the keys to input the
                                              instructions. Up to three separate short programmes can be entered. When the programmed PIC is running, the two
                                              inputs are used to select (and change between) programs. This effectively provides ‘IF’ functionality.
                                              The Chip Machine, complete with keyboard, is less than £20. It is fully portable and uses the lowest cost PIC – thus
                                              making it very attractive for foundation work at Key Stage 3.

         DESIGN DECISIONS IN DMA’S   Dr. David Barlex expands on his article from the last issue
                                     exploring ways we can plan-in design decisions for pupils.

                                     DESIGN DECISIONS –
                                     THE KEY TO SUCCESS IN DMA’S
                                     Pupils make design decisions when they tackle designing and making assignments
                                     (DMAs). In these assignments pupils are expected to generate and develop design ideas
                                     and then make a prototype product based on those design ideas, which can be
                                     evaluated against the performance criteria the design was intended to meet.

                                     In dealing with novice designers (your
                                     pupils) you can orchestrate the number
                                     and complexity of the design decisions
                                     that the pupils have to make in carrying
                                     out a design and make activity in order to
                                     ensure that the assignment is
                                     appropriately challenging without being
                                     daunting and requires pupils to use
                                     particular parts of the design &
                                     technology programme of study. So an
                                     important first step is to audit the range
                                     of design decisions that are likely to be
                                     made by pupils tackling the assignment.

                                     This audit can be carried out using five key areas of design decision: conceptual (overall
                                     purpose of the design, the sort of product that it will be), technical (how the design will
                                     work), aesthetic (what the design will look like), constructional (how the design will be
                                     put together) and marketing (who the design is for, where it will be used, how it will be
                                     sold). This can be represented visually as shown in Figure 1 with each feature at a
                                     corner of pentagon and each area of design decision connected to each other area. This
                                     inter-connectedness is an important feature of design decisions. A change of decision
                                     within one area will affect some if not all of
                                     design decisions that are made within the                       Conceptual
                                     others. For example if the way a design is to
                                     work is changed this will almost certainly

                                                                                                                              Te hn
                                                                                                                              Te hn

                                     affect what the design looks like and how it

                                     is constructed. It may also have far reaching

                                     effects in changing some of the purposes

                                     making design decisions in the other areas.     when tackling a DMA.

                                     Consider the designing and making of a puppet theatre and puppets. The pupils can
                                     make decisions about who will use the puppets and what for (marketing decisions),
                                     what sort of puppets would be appropriate, the sort of theatre such puppets would need,
                                     the nature of props and scenery plus any special effects that might accompany the
                                     performance. These decisions will encompass a host of technical, aesthetic and
                                     constructional design decisions.

                                     Designing and making simple sensing devices is a standard activity at Key Stage 3 –
                                     almost the equivalent of the teapot stand of yore. What range of products would be
                                     obtained if pupils were empowered to make design decisions instead, as is often the
                                     case, produce the working circuit and place it in a case produced from a former provided
                                     by the teacher?

               The examples shown in the panel show possible responses at basic, intermediate and advanced
               levels using construction techniques accessible to pupils at Key Stage 3 – attractive forms from
               nets (or surface developments as we used to call them). The brief for the DMA is to design a
               temperature sensing device that could be sold in a chain of shops that provided goods and
               materials for people who owned and cared for pets. The basic response is simple a two part
               divided box to hold the sensing circuit and battery decorated to show which pet it is to be used for.
               The intermediate response is a box to hold circuit and
               battery but shaped to resemble the pet it is intended for.
               The advanced response is a combination of five nets
               giving a complex 3D form representing the pet it is for. In
               these responses there was no conceptual or marketing
               design decisions but considerable aesthetic and
               constructional design decision making at different levels
               of sophistication.

               As far as technical design decisions are concerned these
               can be made in differentiated ways as follows:

               »   The pupil assembles a given sensing circuit using
INTERMEDIATE       given components and given printed circuit board –
                   no technical design decisions
               »   the pupil designs the printed circuit board layout
                   which she uses with a given circuit and given
                   components – basic technical design decisions
               »   the pupil has some choice of components within a
                   given circuit and produces the printed circuit board
                   design – intermediate technical design decisions
               and finally
               »   the pupil designs the circuit including component
                   values and designs a suitable printed circuit board
                   layout – advanced technical design decisions.

               TEP has developed a range of resources that allow pupils
               to meet these different levels of technical design
               decision-making. Note it is possible for a pupil to produce
               a basic design with regard to the net, which encloses an
               advanced circuit and vice versa. It will be the guidance
               that you provide that will allow a pupil to maximise their
               design decision-making.

Phone PIC Is the latest and possibly one of the simplest ways of
programming PICs. This pioneering system uses any mobile phone for
programming. It consists of a small programmer circuit board with a
microphone. To programme you simply hold a mobile phone earpiece
near the microphone and enter your programme using the dial-up
keypad. The Phone PIC responds to the acoustic tones (DTMF tones)
generated by each key and translates these into program instructions. In
newer mobiles, the numbers pressed appear on the LCD screen, thus
visually recording the start of any program entered. It is even possible to
program a PIC at any distance by phoning a third party who then holds the Phone PIC
near their own mobile! The Phone PIC will accommodate existing 18 pin PICs such as
16F84 and 16F627 which are supplied partly programmed AT NO EXTRA COST. Because
the Phone PIC firmware is in the actual PICs used, the system is future proofed against
any possible upgrades. The Phone PIC is supplied ready to run and features a ZIF (zero
insertion force) socket making it very easy to move PICs in and out without damage.

This system represents a sensible low cost alternative investment in PIC
programming and will provide a robust and exciting new approach to
the technology and will stimulate and generate a lot of interest
                                          in pupils and

                                     Penny Bailey is a TEP associate and was appointed as Head of Department for Technology at Shipston
                                     High School in 2000.

                                     Penny takes up their Millennium experience:
                                     When I arrived at SHS it was with horror that I realised Ofsted was due at the school
                                     within 3 terms. I discovered the department had been put forward for the Millennium
                                     Project and felt it would be an interesting experience as I had to write up schemes of
                                     work for Key Stages 3 and 4, department plans, assessments schemes and any help in
                                     this would be beneficial. I had already used the Post It Note Organiser project at my
                                     previous school and had been impressed by the project and pupil outcomes.

                                     The school timetable is taught on a fortnightly basis. All lessons are 50 minutes long,
                                     with 6 periods a day. In Year 8 the whole year group is very small, so they come into
                                     the department as a year group. This has the advantage that all technology staff are
                                     on at the same time and allows us to change the groups around to create the best class

                                     There are 4 specialist technology rooms based together, 2 resistant materials
                                     workshops, a technician base and office/storage area. Upstairs is a graphics room
                                     with 15 networked computers and a CNC milling machine are close by. The small sizes
                                     of all technology rooms are a problem and there are very little areas for storage.

                                     Both Keith and I are united in our belief in pupils designing and making quality products that will ignite family
                                       admiration not sympathy when they go home. Pupils need to take home products that are appropriate technology
                                          for them and the society that they live in. So we were attracted to projects offered by TEP and the reactions from
                                             pupils were extremely encouraging. They certainly created the Wow factor we hoped for. Older pupils were
                                               extremely fed up not to have produced the TEP projects. Taken along to parents’ evenings the exemplar
                                                products also created a stir and jealousy with nearly all parents!

                                                 In year 1 of the Millennium project we offered the Mouse Mate as an introduction to Technology for Y7.
                                                  Pupils had the option of including tie dyeing the fabric backs before printing the ICT generated design and
                                                  or applying smart inks to enhance their designs if they wished. We chose not to include the milled out
                                                  space for a floppy disc as we followed this process with the CAD torch project. In this first year we followed
                                                   the project to the letter and discovered that this Y7 were not coping so well with the instructions to
                                                      producing the three layered torch body and as a result too many of the designs would not machine
                                                         well. One of the great joys of the millennium project has been the opportunity to discuss, argue
                                                           and laugh over problems created by pupils with DT colleagues from Warwickshire, Yorkshire and
                                                            Derbyshire. We discovered that staff from Lady Manners School in Derbyshire had come up with
                                                                  a solution to the problem of milling out and had reduced it to one layer using 8 mm acrylic.

Yr8 pupils made Post It Note Organisers, PIC based Jitterbugs, Flat Torch as well as Food
Technology. Having an abundance of really good projects allowed us to choose appropriate
projects for some groups. At SHS the groups are set according to their Maths and English
abilities and allow us rightly or wrongly to differentiate by tasks as well as outcome. A few
pupils have special needs with poor listening and sequential skills; as a result tasks have
to broken down into very small steps with guaranteed success built into projects to boost
their self esteem, confidence and therefore progress. That sequential approach is made
easier with these millennium projects. All our Y8 pupils really enjoyed the projects and
were especially taken with the jitterbugs.

As Yr9 curriculum was to be changed in the second year of the project we ran our own
projects for the first year, however in contrast with the millennium projects they looked
tired, with a poor quality of outcome. Many were left in the cupboards and proved to be
great kindling wood for Keith’s Aga!

In the second year of the millennium project we adapted the CAD torch project to create a torch / keyring
with a milled maze game and LED cut out of 8 mm acrylic. With year 7 pupils we used a template to
create a CAD design for their torch that they printed out to use as a template in the workshop. They then
used hand wastage methods to create the torch. On finishing we returned to the computers and they
learned to use Pro/Desktop to draw a simple version of their torch design as extension work. This
delivery of the CAD torch project produced a 100% successful outcome.

Y8s have continued to make Post It Note Organisers and there is the opportunity to incorporate a Batch
Production theme with suitable groups. I have organised this project so that pupils work in groups or
“factories” to produce a batch of organisers with pupils taking different roles within the factory. With
able pupils, they can be taught about tolerances, the roles of H & S. etc. Group presentations can be
               arranged with a “client” found from within or outside the school community. Various
               groups from Y8 have also tackled the Battery Tester project in different ways. A more able
               group were given the challenge of developing the flat battery tester into a 3 dimensional
               product. They explored a choice of nets that would combine an inner net to carry the
               circuit and an outer net for the surface graphics. I found that this created an enormous
               amount of problem solving for them, provided discussion points about the role of
               packaging and environmental considerations.

               Yr9s have all made Aroma fans but again we adapted the project for them and to match our resources.
               As we have no circular saw we had to make the shell larger with thicker material. Initial reaction from the
               pupils made us believe that we needed to add a secondary purpose for the Aroma Fan so we adapted it
               to be a desk tidy as well. In practice this proved doubly appealing to pupils. Y9s also had a go at the
               Message in a Box project, programming PICs to light a seven segment display to create text, a letter at
               a time. With an able group I delivered this as a DMA,
               and while this has produced some interesting
               outcomes e.g. a periscope, assorted picture frames
               and containers, however this can take time away
               from the programming of PICs. More recently we have
               created a ‘message in a bag’ graphic product
approach with a high degree of popularity. In the future I may well
deliver this as a focused task.

Y9s also undertook a project that introduced them to Pro/Desktop
in which they designed a camera using CAD and free hand
sketching skills. They will also be designing and making a mobile
phone stand and a bubble blower this year.

As new courses for Key Stage 4 had to be written we incorporated some of the TEP/SHU projects into them. So in the
first year the GCSE Resistant Materials group all made Post It note Organisers, looking at Batch Production methods.
In this current year Y10s have all made an Aroma Fan and have been encouraged to explore the form through
experimentation with some interesting architectural influences. This year our year 7 are working on an all new desktop
design mobile phone holder too. The Millennium projects have influenced both the pupils in Key Stage 4 and the staff.
We have transferred techniques and skills into Key Stage 4 projects. The pupils have seen the Key Stage 3 outcomes
and I’m sure it has helped raise the quality of outcomes both in Resistant Materials GCSE as well as Graphic Products.
Our department results continue to rise dramatically and are in no small part, due to the influence of TEP projects and

          Claire Ford of the Smallpeice Trust gives us a brief insight
          into the impact and success of their programmes

    What is the
    What is the
    Smallpeice Trust?
    Smallpeice Trust?
          The Smallpeice Trust is a highly respected and professionally executed programme
          of tiered schemes to promote engineering as a career to young people. The core
          programme consists of subsidised training courses held each year at residential
          schools for students ranging from the age of 14 through 17 and a Gap Year for
          pre-university students. Hands-on project work is a vital element of each course.

          A strong interface is maintained with industry, education and professional bodies who help to support,
          promote and develop these courses. The Trust has a reputation for developing and delivering courses
          to a high standard and has built on these relationships to extend the programme in 2004, and provides
          a number of tailored or specialised courses.

          The core Smallpeice courses are affiliated to The Royal Academy of Engineering Best programme.
          Students receive expert tuition in a variety of engineering-related and management skills presented
          by consultants and industry specialists.

          The pathway to a career in engineering
          Over 400 young people have had the opportunity to experience engineering first hand with The
          Smallpeice Trust this summer through a series of four day residential training courses held at UK

          During the last twelve months the core programme for 14 to 17 year-old students has increased
          to include several specialised courses.
          The Marine Technology Experience, held at Southampton University, sponsored by Lloyds Register,
          supported by The Royal Navy and Young Engineers, encourages students to investigate real-life
          specifications of ship building, whilst taking part in marine technology projects and visits, which
          this year included the Oceanography centre.

          Following a successful pilot, the Electronic Engineering course proved to be even more popular, and
          will run again in April 2004 at the University of Leicester. Designed to inspire and encourage young
          students to consider a career in electronics, the course includes an introduction to Analogue and Digital
          electronics, and a ‘solder and keep’ workshop. The team challenge is to design and build a buggy using
          sensors and remote control to negotiate a circuit, ending in a race against time. Great Fun!

          March saw the introduction of another specialised residential course, Smallpeice Materials Experience.
          Under the guidance of professionals, 40 students will have the opportunity on the next course in
          January 2004 to develop their knowledge and skills in the application of materials science – from
          theory to reality - through a special partnership between The Trust and The University of Oxford and
          supported by Oxford Materials.

          Other specialised courses are being developed for 2004, which will be announced in due course.

          For Year 9/S2 students Smallpeice will present the Engineering Experience course twice in April 2004
          to meet the high demand for places. This course is the starting point for many students who wish to
          find out about a career in engineering, they learn from taking part in practical “design and make”
          projects with graduate engineers from industry, enjoy a challenging experience and make new friends.
          Because of the popularity of this course, early application is strongly advised to avoid disappointment.

          Smallpeice courses provide curriculum enrichment of maths, science and technology through practical
          application of engineering design and associated skills, together with management and business skills
          for personal and professional development.

Teacher Participation
All Smallpeice courses are fully supervised with the help of teachers, many of whom continue to say
how much they also benefit from attending the wide variety of lectures and workshops on the residential
courses. Each teacher on each course receives gift vouchers to the value of £200 and travel expenses.
Smallpeice are always pleased to hear from teachers who would like to take part in any Smallpeice
residential course.

The Smallpeice Engineering Gap Year
For students of engineering this really is the pinnacle of gap years. It provides a unique combination of
study, language tuition, travel and work experience in Europe. The course is intensive, demanding and
great fun – not only an important stepping stone in the career development of young engineers but a
truly memorable experience to carry through life.

The latest intake of students, who were accepted onto the Smallpeice Engineering Gap Year 2003/2004,
have just commenced the course. They spent the first week teambuilding in Devon. The students had the
opportunity to get to know each other and test their strengths and weaknesses against other members
of the group. They are now on their three months of academic study at Seale-Hayne, Plymouth University.
Here they will be developing their knowledge, understanding and skills of engineering and management.
                                                                                                                               Team building exercises
In the second phase of the course the students will go on to develop their language skills on a four week                      not for the fainthearted!
course at a language school in Chambéry, Munich or Barcelona. The tuition they receive is generally to a
conversational level, but students who have an appropriate language qualification may progress to
technical level.
The final phase is a three-month industrial work placement. The students will undertake a placement with
one of our European Industrial contacts, which are established in nine European countries. Some English
speaking placements can be arranged for students who are less confident in a foreign language.
The work will involve more than “shadowing”, as students will be involved in projects as they arise
and be expected to contribute to company activities.

The Students
Nineteen-year-old student, Richard Beardmore (right), was one of only 30 students selected from across
the UK to participate in the scheme last year. Following on from the academic study, Richard spent three
months polishing up his language skills at Deutsch in Deutschland Institute in Munich before spending
three months at engineering company KUKA Schweissanlagen GmBH in Augsburg, Germany.

The programme is run annually over a 7-month period, spanning from September to May, finishing well
                                                                                                              Student Richard Beardmore who was

     This is the first in a series of articles by John Cook a TEP associate with wide experience of all things PIC based. Aimed at
     colleagues who as yet have not found the joy of using PIC’s, confidently and reliably. The PICAXE programming system is
     commonly used in schools today and was developed by Clive Seagar of Revolution Education.

     For the past twenty years 555 Timers, 741 Operational Amplifiers and Decade

     pupils for the real world then this sort of technology should be an entitlement for
     all pupils.

     As can be seen this chip has 5 input / output pins. Pin 0 must always be an

          The ’smell’
          Good design and technology project ideas are
          often difficult to derive. They not only have to satisfy
          curriculum requirements, departmental resources
          but also, and possibly most importantly, capture and
          stimulate pupil’s imaginations. Product desirability
          is the key to promoting pupils enthusiasm for design
          and technology and is a positive platform to develop
          teaching and learning.
          Jenny Dein TEP teaching fellow at Sheffield Hallam
          University gives us an insight into one such product.
          The Aroma Fan is one such project which can fuel
          imaginations and adapt to individual school
          circumstances. It is one of a suite of ten projects
          from the TEP Millennium Schools Project developed in
          association with Sheffield Hallam University which are all are supported by teacher guidance unit
          publications. The Aroma Fan is a project concept which can be differentiated considerably to develop
          designing and making skills at various ability levels at Key Stages 3 and 4 in resistant materials,
          electronics and textiles.

          The Aroma Fan
          Throughout history, in many different cultures, perfumes, incense,
          aromatic plants and oils have been used to enhance human experience.
          Aromatherapy is the practice of dispensing aromatics not only as
          physical remedies but also to stimulate the senses to influence the
          mind and emotions. It has also been used to contribute to the remedy
          of some physical conditions.
          The Aroma Fan is designed to appeal to a variety of senses, to enhance
          the environment in which it is placed and to fit in with contemporary
          styles and fashion.

          This project consists of a natural wood structure incorporating a motor
          and fan controlled by a simple electronic circuit. The fan draws in air
          through the base of the structure and blows it through absorbent
          material impregnated with vapourising oils or similar fragrant
          preparations releasing the aromas into the atmosphere through
          cool dispersion. The fan is controlled by a monostable circuit that
          is triggered by a touch sensitive panel switch cast from pewter.

                                           The project concept provides many opportunities for pupils to develop
                                           their own individualised product and make decisions regarding scale,
                                           materials, construction, finish, structure, function and level of control.
                                           For example, the Aroma Fan could be controlled just with a motor and fan
                                           with just an on switch as a less sophisticated level of control. For more
                                           advanced ability levels light or sound could be introduced extending
                                           the variety of responses and could be controlled using a PIC (Peripheral
                                           Interface Controller) or an IQ board (a discrete programmable controller).

                                           There are essentially five sub assemblies to the Aroma Fan. Shown
                                           in the table are exemplar solutions but the type of components and

Touch sensitive timer circuit
The use of a touch sensitive switch allows the fan to be switched on by simply touching a pewter
decorative plate located on the outside of the Aroma Fan construction. The monostable circuit will
operate the fan for a few seconds and then switch off until the switch is touched again.

The Circuit

                                      The monostable timer circuit suggested in the teacher guidance unit
                                      provides two operating options. The circuit using standard components
                                      (555 timer chip) will operate on 6V (4AA batteries). To save battery
                                      consumption in the standby mode this arrangement requires an
                                      on/off switch as shown on the diagram.

                                      Alternatively the same circuit board can use a 7555 timer chip.
                                      This will run on 3V using 2AA or 2AAA batteries without the need

Tuning of the 100K preset resistor enables the time period that the fan remains on to be adjusted.
If longer time period is required, a larger capacitor can be used.

                                The switch component is manufactured by casting pewter into a two part
                                mould. To enable connection to the circuit board a 1mm hole is drilled into
                                one part of the mould to allow a single stranded wire to be inserted into the
                                mould cavity. This is counter-bored to a depth of 6mm with a 6mm drill to
                                produce a collar around the wire when cast. Pewter is then heated to molten
                                temperature in a ladle or small
                                crucible and poured into the
                                mould. A small ring of plasticine
                                will aid pouring. Once cooled
                                the position of the plate is
                                marked on the box and a 6mm

           DATA, the Design and Technology Association, is an educational charity and the
           professional association representing all those involved in design and technology
           education. As part of its overarching commitment to promoting the advancement of
           design and technology education they publish a broad spectrum of informative
           resources across all phases.

           The following article is one of a series published in the magazine Modus, made
           available to all DATA members and is now reprinted here.

                   KS3 Strategy

        DESIGN & TECHNOLOGY     Year 7 Electronics / Control activity
                                                                       Unit of Work : Musical Greetings Card
                                                                                     QCA reference : Unit 7D

           The context here is the design and development of a musical greetings card. This activity uses the
           context of celebrations as an interesting and motivating way to introduce pupils to the design and
           development of their own musical greetings card. Pupils use a number of common basic electronic
           components as well as a sophisticated ‘electronic black box’ – a music/sound chip.

           This unit is suggested as a possible first unit on electronics and communications technology in Key
           Stage 3. The main leaning objectives for this activity would be related to:

               »   understanding the basic concepts of input, process
                   (limited to a driver subsystem and a melody generator IC) and output
               »   understanding digital electronic signals
               »   selecting and using a range of input sensors and output devices
               »   component recognition and handling
               »   developing skills in assembly and soldering
               »   a knowledge of the manufacturing process.

           There may also be some objectives related to sequencing commands in a control language,
           checking electronic signals, simple fault finding techniques and pcb design (depending on
           approach adopted).

           The notes that follow here represent the first few lessons that would be undertaken as part of this
           activity. It is helpful if pupils have already worked with basic electrical circuits and had some
           experience of simple graphic design techniques – shaping and folding card, use of colour, light and
           dark, shading, rendering textures. Pupils should have gained the above knowledge, skills and
           understanding in Years 5 and 6, through QCA unit 5A ‘Musical Instruments’, unit 6A ‘Shelters’, unit
           6C ‘Fairground’ and unit 6D ‘Controllable vehicles’ in the Key Stage 2 scheme of work, or similar

           The pupils have been asked in a previous lesson to bring in examples of ‘musical’ or ‘talking’
           greetings cards. A selection of such cards is also available for pupils to use.

          Keiron McGeever takes a month off robotics articles to remind us about the possibilities
          of the TEP Rocket Factory and the things we can do when the weather gets warmer.

          This IS Rocket Science!
          I was excited the first time that Frank Muraca demonstrated the TEP Rocket Factory to me and I could not
          wait to try it out for myself. Firing rockets 30, 40, 50 metres into the air is great fun and highly motivating
          to children for the first few goes, but for any real learning to take place there needs to be another element to
                                          the work. What it reminded me of were my Maths lessons at school (way back
                                          in the middle of the last century). I was lucky and went to school before the
                                          National Curriculum was invented and even luckier to have a maths teacher
                                          with a bit of imagination when it came to teaching formulas and graphs. He
                                          introduced the topic by getting the class to fire rocks into the air from catapults
                                          (think of the health and safety issues around that today and the risk
                                          assessment!) and then he showed how, by timing how long the rock was in the
                                          air, we could plot graphs of the flight of the rock from which we could calculate
                                          the height the rock got to and the maximum speed it achieved during the flight.
                                          The Rocket Factory allows you to do this much more safely and I came up with
                                          the idea for a competition called Rocket Day.
                                          Rocket Day was intended to show that Technology can not only make Maths
          and Science relevant but also FUN. There are three elements to a Rocket Day competition, the highest flight,
          the longest flight and the most stylish rocket. Teams of up to four pupils are formed and they design and
          make rockets for each of the three events.
          Many schools already have the Rocket Factory and can ‘fire up’ integrated maths and science into a Rocket
          Day activity. The Rocket Factory comes complete and ready to use and is available only from Teaching

          3. How high can you fly?
          At first sight the problem seems easy. Making a rocket for the TEP Rocket Launcher is simple, wrap a
          sheet of A4 paper round a plastic tube, stick a nose cone and some fins on it, and there you are. The
          difficulty starts when you try to make the rocket go as high as possible, you have to balance out the
          weight of the rocket versus the power applied to it and the drag of it flying through the air.
          2. How long can you go?
          Trying to get the rocket to stay in the air as long as possible has so far proved to be almost impossible,
          as can be seen from an actual table of results on the next page. No team has managed to get their rocket
          to stay in the air for longer than the highest rockets time. This was due to the fact that devices added to
          the rocket to make it come down slowly also made it go up slowly, resulting in very little height gained,
          therefore a very short flight time. So this is a problem still to be solved.
          1. How smart are you?
          The Best Looking Rocket event is mainly a bit of fun, but the rocket still has to be launched, and this can
          result in some of the funniest happenings of the day as a lot of the fancy add-ons don't stay on. There
          can be a lot of flying debris. The most difficult part of this event is deciding who has made the best-
          looking rocket and it can result in a lot of controversy.
          Liftoff- Getting the total right
          At the end of the competition the overall winner is decided on the total points scored for all the events
          and is done using a spread sheet. See the example at the end of the article. The spread sheet is set up
          so that it not only calculates the total number of points, but it also works out the height a rocket has
          reached and the maximum speed it achieved during its flight.

          Doing the Maths and Science
          Tracking the Rocket
          The altitude of the rocket can be measured directly with an inclinometer (see fig 1).                                 fig 1
          To do this, do the following:
           » Keep the ascending rocket in view through the sighting tube.
           » Lock the angle of the inclinometer at the highest point. (Angle a)
           » Measure the distance from you to the rocket launcher. (Distance d)
           » Use the formula tan a x d = h (h is the height of the rockets flight).

                                                                       For greater accuracy it might be a good idea to use more than one inclinometer and
                                                                       to average the results (see fig 2). This method is quick and simple but susceptible
                                                                       to a lot of errors; it also gives only the height that the rocket achieved and not its
                                                                       speed. For a more reliable method you have to delve deeper into the science.

                                             Notes on Gravity, or “Why things fall down.”
                                             But first, acceleration and velocity
   Time in seconds         Velocity in m/s   Acceleration is the rate of change of velocity (speed) with respect to time and Velocity is the rate of change
                                             of distance with respect to time. For example a car travelling at 5m per second will travel 5m for every second
               0 seconds             0 m/s
                                             it is moving, its velocity is constant. A car accelerating at 5m per second per second will have its velocity
                                             increase by 5m/s for every second that it is moving, its velocity is not constant it gets faster and faster.
       1 seconds                    10 m/s
                                             Gravity is a force of attraction between any two bodies that have a mass. I am attracted to the Earth by the
 2 seconds                          20 m/s   Earths gravity and the Earth is attracted to me by my gravity (please note the two masses are vastly
                                             different!). The greater the mass of an object the greater the gravitational attraction it has to another body.
                                             It is gravity which gives an object weight, not to be confused with mass.
                                             Gravitational attraction between two bodies causes them to come together with a greater and greater speed,
                                             it accelerates them. On Earth the effect of gravity is expressed as the letter g and 1g = 10m/s/s (approx.) This
3 seconds                           30 m/s   means that if a ball is dropped from the top of a high building after 1 second the ball will be travelling at
                                             10m/s, after 2 seconds 20m/s and so on (see fig 3). After 3 seconds the ball will be travelling at 30m/s which
  fig 3                                      equals 108km/hr which equals 68m/hr, therefore gravity out performs a Ferrari.

                                             The effects of gravity on a Rocket
                                             When the rocket is going up, gravity works in reverse slowing the rocket down until it reaches a velocity of
                                             0m/s and then it falls back to earth. This means the flight of the rocket is symmetrical and that half of the
                                             flight is the same, mathematically, as if the rocket had been dropped from a great height.
                                             Therefore the simple way to work out how high and how fast your rocket has travelled is to use the formulas
                                             for the effects of gravity on an object and to do that you need to time the length of flight of the rocket from
                                             when it leaves the launch pad to when it hits the ground again by using a cheap stop watch. You can then
                                             substitute big T divided by 2 for little t in any of the formulas. (T equals the time of the flight in seconds).

                                             Calculating the effects of gravity on a Rocket
                                             To calculate the maximum speed your rocket achieved during its flight use the formula vf = g x t. This gives
                                             the speed (vf) after t seconds. A free falling object accelerates at 1g (the accurate figure for this is
                                             Similarly the distance (d) a free falling object travels can be found
                                             from the formula d = 0.5 x g x t2
                                             Simply calculating the effects of gravity on a Rocket
                                             The simple way to calculate the effects of gravity on the rocket is to use a
                                             spreadsheet such as Excel and to set it out as shown in the example below.
                                             You can put any of the formulas into the spread sheet, depending on how you
                                             want to calculate the height of the rocket and it will work out the results.
                                             I have used this many times with groups from different schools, but it can be
                                             done just as well with a class group even spreading the event over several
                                             lessons. Projecting the spread sheet onto a screen adds to the atmosphere of
                                             the event by allowing the teams to see how they are progressing.

                                             As an inter-school event the way I have organised it in the past is to take a whole day to do it in, spending the

                                             a little ingenuity an event can be adapted to suit your own environment. It would be great to do during an
