Never mind the baubles!

HERE'S THE XMAS ENTRIES!

You have been sending in some great entries to our Christmas competition, which is now closed. Do not enter now as your entry will not count and you may still be charged! Even though we relaxed the strictly festive rule, that did not stop many of you from sending in seasonal entries or those on a Christmas theme.

Inside a locked room somewhere at Rapid, the judging is now taking place. No one is allowed to leave until a winner has been chosen, and no white smoke has yet been spotted, so in the meantime you will have to amuse yourselves by viewing some of the best entries we have received.   

Here is Peter Fox's home automation system




Dean Gallagher's Bipolar Slayer Exciter




Owen Wright's Rapid Christmas decoration



The Lighthouse Tree

Ed Kilgore made a lighthouse tree for a Christmas Tree festival for his church in Newcastle. A nice combination of Blue Peter type ingenuity (the lighthouse shell is made from a traffic cone) and solid electronics, including an integrated Riding Santa kit, the model illustrates a verse from the Bible linked to the Christmas story: "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life".




Thank you to everyone who has entered. The winner will be announced on Tuesday 23rd December.

James Bell

James Bell, Rapid's Managing Director, gives his views on the state of the electronics industry and looks forward to 2015.


2014 has been a year of significant growth at Rapid. The number of lines has nearly doubled in less than two years and next year the company will continue to expand its range and depth of product.

We expect to see a significant increase in new customer acquisition in 2015, while retaining a strong order book for existing customers. It is clear that buyers have greater choice and the market is becoming incredibly competitive. The online sales migration is definitely making customers more aware of product availability and price and Rapid will be investing in stock and adding new tools to its online offering in 2015.

The outlook for the electronics industry is one of uncertainty. Global instability does not help and I am concerned that falling oil prices will eventually lead to a downturn in production. This will have an impact on the global economy as the pendulum swings the other way and demand starts to outstrip supply. I believe the industry will maintain good growth in the first quarter of 2015, but I would hesitate to make predictions further than that.

Rapid, however, is appropriately sized and staffed to respond quickly to change. We look forward to working with new suppliers, increasing our market share and delivering continued growth throughout next year.

I would like to take this opportunity to thank all of our customers and suppliers for their support over the past year and wish you all a very Merry Christmas and prosperous New Year.

Chips, beer & automated cars

What were the best things on show at electronica last week?

As the world's largest event for the electronics industry, electronica 2014 drew 73,000 visitors from over 80 countries and 2,737 exhibitors. Business managers, salespeople, engineers and CEOs convene every two years to network and check on the latest developments in electronic components and applications. With such hordes tramping through the vast Munich exhibition halls, companies are under pressure to demonstrate their technology and products in ever more entertaining ways. Marilyn Monroe lookalikes and supercar giveaways are all very well, but we doubt they will make the lasting impact of a really memorable bit of tech.

So here are some of the highlights from electronica 2014.

Maxim Integrated's Beer Mug Factory

Chips and beer - always a winning combination with thirsty, hungry delegates. IC specialist Maxim Integrated hit upon the perfect way to keep a long line at its stand with a robot which processes and delivers personalised beer tankards. Demonstrating the versatility of Maxim's analog, digital and mixed signal chips, sensors, power supplies and high speed communication products, the beer mug production line is controlled by an iPad; it takes about two and a half minutes to fully process each customer's stein, which is printed with the name of the customer and their favourite beer.



Osram's gesture recognition controller

Imagine being able to spin the globe in Google Earth without clicking a mouse or touching your screen. Osram's new gesture recognition controller enables you to do just that. Containing three Osram IR LEDs and two IR cameras devices, the controllers sense hand movement over a specific point which doubles as the screen of your device. Watch the video here.

The car a quadriplegic can drive 

Arrow Electronics demonstrated SAM, a Corvette Stingray modified to allow Sam Schmidt (right), a former US Indycar driver, the opportunity to drive again. Sam lost the use of his arms and legs after an accident in 2000. Arrow built SAM (semi-autonomous motorcar) so that it can be controlled with just the driver's head. The driver wears a baseball cap with reflective infrared sensors which record the pilot’s head movements, while software translates the head movements into steering wheel impulses. To actuate the brakes, the driver bites on a hose with a pressure sensor.


USB 3.0

Industry foecasts predict that global sales of USB 3.0 enabled devices will reach 3 billion units by 2018. The major market driver is expected to be the need to increase transmission speeds between peripheral devices and computers. FTDI Chip announced its first generation USB 3.0 products at the show. The FT600Q and FT601Q are designed for use in FIFO bridges, featuring support for data bursting rates of up to 3.2 in products such as cameras, printers, scanners and industrial applications.

IoT is dead; long live US (not The US)

And apparently the IoT is dead. Internet-enabled sensors will so envelop our lives that it will be a world of "ubiquitous sensing". What opportunities and challenges will this present? A roundtable of leading CEOs from the semiconductor industry debated the implications of such connectivity, in particular their concerns about usability, security and what it means for semiconductor manufacturers.
We are moving on to a world where sensors will be monitoring everything and collecting data to a mindboggling degree.
The IoT has morphed into a new phrase “ubiquitous sensing”. This is the important aspect of IoT which was missing and which I can now understand.
Sensors will change our lives. The numbers start to look achievable.

Nine words that changed the world

Alexander Graham Bell
Mr. Watson — Come here — I want to see you.

With these words, spoken on 10 March 1876 in his lab in Boston, Alexander Graham Bell made the first telephone call. The US patent for the 'acoustic telegraph' had been issued to the Edinburgh-born inventor only three days previously, and now he had proved that electrical current could transmit the vibrations of human speech. The 'Watson' was Thomas A. Watson, an electrical designer with whom Bell had been working for several years on a multi-reed device that could send multiple tones on a telegraph wire.

Bell's was one of the great inventions of the modern age, but it was through his interest in human speech rather than technology that he stumbled upon the telephone. In fact, prior to his breakthrough he had made his name as a teacher of deaf children and pioneer of sign language. While people were amazed at its first demonstrations, the telephone did not make Bell's fortune immediately. In fact, the Western Union telegraph company refused to pay $100,000 for Bell's patent in 1876. Two years later the Western Union president admitted that if he could get the patent for $25m he would consider it a good deal.

Bell developed the telephone over the rest of his life, demonstrating it amongst others to Queen Victoria (who confessed it 'most extraordinary') amongst thousands of other astounded visitors at exhibitions around the world. By 1915 he had demonstrated the first transcontinental telegraph voice message. No longer in an adjoining room, Watson was this time 3,400 miles away in San Francisco. The New York Times reported that "Dr. Bell, the veteran inventor of the telephone, was in New York, and Mr. Watson, his former associate, was on the other side of the continent. They heard each other much more distinctly than they did in their first talk thirty-eight years ago."

Bell demonstrating the telephone

AGB also filed patents for the phonograph, dabbled in hydro engineering and anticipated the modern interest in magnetic media and renewable energy. Who better then, than to ring the opening bell of Rapid's Young Inventors competition?

School's out - but not for coders!

It is the ultimate summer school for coders.

Young Rewired State is a global community of self-taught young coders under the age of 18 who use their digital skills to "program the world around them". Every summer YRS stages a Festival of Code. It is a sign of the progress coding has made that when the festival was first held, in 2009, it took its co-ordinator Emma Mulqueeny "three months to find 50 young coders in the whole of the UK". At this year's festival, held recently, over 1,000 children took part at 61 centres across the country.

During the week the young programmers built apps, games, websites and projects, some just for fun and others which met real-life needs and challenges. The venues included the Raspberry Pi Foundation offices in Cambridgeshire and the Compare the Market HQ in Peterborough. After brainstorming ideas they worked on their projects. All that is asked of the participants is that they use one piece of open data. Teams had access to a mentor who could offer advice and support, but otherwise the teams worked independently. At the end of the week the teams presented their final projects in front of a panel of judges in a huge 'show and tell' event at the University of Plymouth.


Awards were given for best designs and best use of code, along with unique categories in the spirit of YRS such as "Code a Better Country" and "Should Exist". Among the most popular projects were "YouDraw", a crowd-sourced video animation platform giving the opportunity to create user-generated animated music videos; "Tourify", an app supplying unique customised tours for travellers; and "Miles Per Pound", a website which calculates the cost efficiency of your car. Other more idiosyncratic innovations included an app that measures proximity to danger, a bitcoin exchange rate service and a coat rack weather forecasting device.

Children as young as 8 made presentations that as one adult tech start-up founder commented, "could rival those of people 3 or 4 times their age".


However, it is not so much the winning that matters in Young Rewired State as the coding: perhaps the definitive image of the event is that of hundreds of kids at their laptops, not playing games or wasting time on the web but creating new games and new websites.  The final gathering is a chance to have fun, meet other members of the community and learn from each other. These are the people born after 1997 who, in Mulqueeny's view, are the 'digital natives': children who have grown up around the web and who through 'peer to peer learning' have the skills to shape society and education.




"Digital skills in education has been a hot topic for the past few years", says Mulqueeny. "Young Rewired State, the organisation behind the Festival of Code, was a champion of that effort - but the festival is much more about this community of young people." The Plymouth gathering also included 40 youngsters from overseas as well as a YRS group from Kosovo who presented remotely.

It may make some feel rather old and unskilled by comparison; but it should also leave us inspired and confident about the future innovators, engineers and entrepreneurs amongst us.

The new Raspberry Pi? We'll give it more than a B+

Our integrated circuits product manager Richard Philpot (right) couldn't wait to get his hands on the newly redesigned Raspberry Pi. Here he explains what's new about the Model B+, which is now available from Rapid.

When the Raspberry Pi was released almost two and a half years ago, Eben Upton of the Raspberry Pi Foundation had clear but limited aims for the project. He hoped to shift a few thousand boards to willing educators as a tool to help teach children more about programming computers. It quickly became apparent that they had actually created a groundbreaking piece of 21st-century tech. The iconic Pi has now reached the three million sales mark.

As British industrial success stories go, from design to manufacture (after production switched from the Far East to the Sony factory in Wales), there can have been few to compare with it in recent years. After the first model was upgraded a few months after its release with double the memory, the B+ has now appeared. We are delighted to be one of the lucky few suppliers in the UK. So what has changed with this new version?

More ports, more pins

The major changes are to the board design rather than the OS or processor, which is still the Broadcom BCM2835 SoC. The B+ has found room for two more USB ports, which is a great improvement. If you wanted to connect a keyboard, mouse and wifi dongle to the previous model you would need a USB hub, which sucked power from the board and added more hardware and wiring to what by its nature should be a small footprint device.


The Raspberry Pi Model B+

The GPIO connector header has also been extended from 26 to a 40-pin configuration. Existing headers and ribbon cable connectors will still be compatible with the old 26-pin system. The first 26 pins are in the same pinout as previously, but the extra pins give greater capacity to modify and hack the Pi. However, some headers will not be compatible - it will depend on the size of the bezel surrounding the pins (some are wider than the pin spacing).

The Pi now uses a microSD card rather than a standard SD card. As well as the space and physical benefits of dispensing with a large SD card tray, the NOOBS load out means that the Pi will require an 8GB microSD card. 4GB may be enough but it will be a close call! Combining separate audio and video jacks into one composite audio/video connector makes for a sleeker board with two sides free of protruding ports. This will be good news for makers of homebrew enclosures, for whom the Raspberry Pi has been an incredibly fruitful muse.



Less power-hungry

The B+ is less power hungry than its predecessor, consuming 2.8W in idle and under load states, compared to the B's 3.1 and 3.8W. Users who integrate their Pi in embedded applications will appreciate these power savings. Other notable changes include neater mounting options with the addition of a further two pre-drilled holes giving a rectangular configuration.

This is only a short summary, but the model B+ has addressed the (admittedly small) list of concerns some people had about the Raspberry Pi. By adding extra ports and pins the Pi designers have set a new standard for single board computers. With excellent community support, open source content and huge array of accessories this will definitely get more than a B+ on user's report books.

However, if you are thinking of ordering, don't hang around - the shelf of B+ boards in our warehouse is getting emptier by the day!


The Pibow Rainbow case for the B+
Custom enclosures have been one of the fastest growing areas of the cottage Pi industry, and the new design has already started to inspire a new generation of cases. We are looking forward to receiving the new batch of Pimoroni's popular Pibow range for the B+. The existing cases, which Liz Upton from the Raspberry Pi Foundation called 'one of the most solid and best looking cases I've seen', are still available from Rapid in rainbow, black, green, clear and translucent yellow.

There are a few other exciting add-ons in the Pi-peline - watch this space for details.

Weltmeister in Wunderland

Who said Germans have no sense of humour? Admittedly, it is easy when you have something to laugh about, but the progress of Joachim Loew's side to the World Cup Final has inspired some lovely little scenes in Hamburg's Miniatur Wunderland, the world's largest model railway layout. Here are just a few of the more memorable.

Self-explanatory really, but perhaps a little hubristic?

The aftermath of "Seiben-Einz".


Kind of Bay-ern-watch? Henning Wehn is funnier, but it's a start.

Ten amazing Arduino projects

These are a few of our favourite Internet of Things, er, things ... to do with an Arduino.

Anyone with the right components, a breadboard and a basic grasp of electronics should be able to accomplish these projects, which for beginners is just a fraction of a glimmer of what can be achieved with the open source platform and the Internet of Things. Most Arduino boards can be used, but we recommend the Uno for its size and accessibility.

Remember, a wide range of Arduino boards, shields and accessories are available at Rapid.  















This list could be as long as you want. Why not post your own favourites below?

Trains, plains & automobiles

As Rapid prepares to launch a new range of model railway components, we take a journey through one of the wonders of the modelling world.

To call Hamburg's Miniatur Wunderland a model railway layout is like saying Disneyworld is an amusement park. Housed in a 70,000 sq ft former warehouse building and first opened to the public in 2001, the 12,378 sq ft layout features seven permanent sections depicting landscapes across Germany, Europe and the US.

It is not only a playground for train enthusiasts. Transport of all kinds move across the spectacular HO 1:87 scale layouts through city and countryside, over land and sea, during night and day. Planes touch down in a futuristic airport, trains climb through mountain passes, ferries float through Scandinavian seas and fire engines race to an emergency on a West Coast highway.

Miniatur Wunderland is the creation of twin brothers Frederik and Gerrit Braun, and maintained by a team of modellers and technicians whose highly skilled work takes place behind the scenes while the main layout is playing host to thousands of visitors a day.

The airport alone took six years to complete, and incorporates 40,000 LEDs, 100 km of electric wiring, 15,000 miniature figures and 1000 meters of railway tracks. 50,000 lines of programming code were required to simulate a busy international hub with 360 take-offs and landings per day.

 

The sections include a modern cityscape loosely based on Hamburg, the Austrian Alps, the Grand Canyon and the Matterhorn. An Italian section is currently under construction, featuring iconic landmarks from Rome and Venice, with French and British landscapes planned to follow by 2020. As the layout has become one of Hamburg's leading tourist attractions, the only limit to its expansion is the imaginations of its creators and the available floorspace.  

Mini cameras at the front of the model vehicles provide a bird's eye view of this magical world, giving viewers of Miniatur Wunderland's YouTube channel some fascinating rides.



Like a modern city the landscape changes from day to day, with temporary structures reflecting events in the real world. A fan fest in an urban park can mean only one thing: the World Cup is on and Germany are winning!

If you are inspired by Miniatur Wunderland to begin your own layout, Rapid can help with a new range of modelling accessories, components and scenery in the same HO scale.

Electronics 1914: it is rocket science

Robert Goddard
Meet the original rocket man.

In 1914, the patents Robert Goddard had filed for a multi-stage and liquid-fuelled rocket were registered. Even before the Great War had broken out, this American physicist had inadvertently launched the space race.

Born in Worcester, Massachusetts in 1882, Goddard had grown up fascinated by the mechanics of flight. Inspired by Isaac Newton and War of the Worlds, he experienced an epiphany while climbing a cherry tree in his father's backyard. "I imagined how wonderful it would be to make some device which had even the possibility of ascending to Mars, and how it would look on a small scale, if sent up from the meadow at my feet."

As an undergraduate he had written papers exploring various aspects of flight technology, such as gyro-stabilisation and rocket efficiency. By 1913 Goddard was a research fellow at Princeton University. He had already developed a calculus-based theory to calculate a rocket's position and velocity in vertical flight, and was planning a sounding rocket with which to explore the atmosphere and provide data to aid future research.

It was while recovering from a serious bout of tuberculosis that Goddard wrote his revolutionary patent applications. 

Goddard's original patent application

In the next few years his research and testing continued, and focused particularly on thrust efficiency - the conversion of fuel into thrust which would hold the key to any successful space-bound rocket. A 1915 static test achieved thrust efficiency of 63% and exhaust velocities of over 7000 feet (2134 metres) - enough to convince the Smithsonian Institution and Clark University to sponsor Goddard's research.

 

Although the military showed an interest in Goddard's work, he remained sceptical and rocketry had no involvement in the technology used in the Great War. Goddard's groundbreaking book, A Method of Reaching Extreme Altitudes, was published in 1919. He was ridiculed by the press in these early years, but after relentless testing and implementation of his technology, it was Goddard, posthumously, who was vindicated.  

The New York Times was forced to issue an apology in July 1969, as Apollo 11 was making its way to the Moon:

"Further investigation and experimentation have confirmed the findings of Isaac Newton in the 17th Century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere."

Turn your cat into a mouse

The Internet of Things, that’s so last year.  It’s all about the Desktop of Things now – banana keyboards, pet-enabled mice, self-drawn joysticks – all courtesy of the MaKey MaKey Inventors kit

“The Makey what?”, I imagine you typing into your alphabetti spaghetti keyboard.

Just a simple PCB, some crocodile clips, wires and USB lead, it can turn anything conductive into an actuator. Created by US technology experts Jay Silver and Eric Rosenbaum, it is among the top 40 most funded tech projects on Kickstarter, having received pledges worth over 2000% of its original target. Like a Raspberry Pi for people who don't have the time for programming, or just want a shortcut to fun, MaKey MaKey (= Make anything into a Key) has already spawned an enthusiastic community and is equally appealing to kids, students, makers and serious prototypers. 



So how does it work? 

First, buy the kit from Rapid. Then connect the MaKey Makey board to your PC, laptop or tablet via USB. Connect one end of the crocodile clips to one of the bottom ‘Earth’ inputs and hold the other end. You have “grounded” the electrical circuit. Then attach one end of another crocodile clip lead to an input on the MaKey MaKey board – there are three interfaces, corresponding to a mouse click, the space bar and arrow buttons on your keyboard or joystick. Attach or insert the clip on the other end of the lead to your keyboard or mouse substitute. Touching the connected item will complete the circuit and perform the appropriate action, as if your piece of fruit (for example) was a mouse.  



Using the MaKey MaKey in conjunction with a video game or piece of music software is really where the fun starts. The clever clogs at MaKey MaKey have even developed a number of bespoke programs to help you get started, but all manner of software and apps are out there to help you get creative with sound, art and vision. 

“But what can I use as my new keyboard?”, I imagine you tweeting, via characters created by splashing around in some internet-enabled buckets.

Pretty much anything that carries an electrical current: 
  • Fruit & vegetables & most foodstuffs
  • People
  • Metal - coins, aluminium foil
  • Water
  • Animals
  • Plants
  • Pets
Yes, even pets. This will very much depend on the relationship you have with your pooch or moggie, but you could use your dogs as piano keys, as this chap has done, or create a photo booth activated by a drinking cat. It will certainly be harmless.



See a gallery of MaKey MaKey projects here.

The MaKey MaKey Inventors Kit is now available from Rapid. The world is your keyboard!

Cutting edge GCSE designs


We love these lamps designed by students at Mortimer Community College in South Shields. LEDs and switches from Rapid were incorporated into many of the designs, which were for final projects in the pupils' GCSE Product Design controlled assessment.

Toucan and rainforest lamp by E. White

Design & Technology teacher Annie Shaw tweeted these pictures and kindly sent us some of the designs from last year to show what fabulous work her students consistently produce. 


"The brief was to design and make a lamp in the style of a 20th-century design movement", Annie told us. The pupils found inspiration in  Art Deco, Memphis and Arts and Crafts designs. 


Pupils used laser cutting equipment to create their designs from acrylic and laser plywood, spray painted the finished product and used a mixture of super bright and normal coloured LEDs to achieve the lighting effects.

Art Deco inspired lamp with turned brass feet

"Within product design, to access the higher grades I encourage the students to use a range of different materials", said Annie. "Making a circuit with LED’s gives them an extra skill within their work and helps to gain more marks".

 

"We used 15mm black rocker switches as well which finish them off really nicely and make them look more professional."

Electronics 1914: Bosch invent the electric starter motor

In the first of a series charting events in electronics and technology from 1914, we make a start - literally - with one of the great automotive innovations. 

It is a romantic image from the early days of motoring. Straw-hatted chaps and elegantly turned out ladies stooping over the crank handle at the front of the car, waking their futuristic beast to life.

Yet in reality it was a hard, dirty and sometimes dangerous job. 100 years ago this month, Bosch delighted all automobile owners and chauffeurs when it demonstrated the world's first safe, commercially viable electric starter motor.

The man responsible was Gottlob Honold, lead engineer at the German company. Honold was a legend in the motoring world after inventing the high voltage magneto ignition system in 1901 - effectively, the spark plug that enabled the petrol-fueled engine to become the automobile standard.

Other manufacturers had worked at developing an electric starter motor, but none were suitable for mass production or met safety standards. Safety was a key element - the hand crank had a tendency to slip, or make the engine kick back and spit the handle back and hit the starter. Robert Bosch (1861-1942), who had already built the company he founded into one of the world's first multinationals, with factories and offices in five continents, was determined to develop a solution that could be mass produced and used in his cars.

Honold's starter motor could be operated by a foot pedal, using electrical power from the car battery. The battery was part of the lighting system Bosch had developed in 1913, which for the first time had given drivers enough illumination to drive in the dark without draining the car's electrical system. "The starter motor is typical of the products Bosch launched in the early days of motorization", said Ulrich Kirschner, president of the Bosch Starter Motors and Generators division. "All of them were designed to eliminate shortcomings in function, operation and safety."

The first electric starter motor weighed 10 kg and delivered just 0.6 kilowatts of power. Today's equivalents weigh between 1.9 and 17 kg and produce an output of between 0.8 and 9.2 kilowatts.

Production of the Bosch starter motor began at the company's plant in New Jersey later in 1914. By the mid-1930s 550,000 units had been sold.

Although the magneto ignition system was to be used widely in German military vehicles and aircraft during the Great War, Robert Bosch himself found war abhorrent. Charities benefited from the profits the company made (although Bosch assets in the US were seized after the war) and during the Second World War Bosch employed Jews at a repair workshop in Stuttgart to save them from the Nazi regime.

Bosch of course went on to become one of the world's leading manufacturers of automotive parts, electrical appliances and power tools, and a wide range of Bosch products are available at Rapid.

Your desert island chips

A few weeks ago it was National Chip Week, which at Rapid has always meant the electronic rather than the potato variety.

To celebrate this year, we asked you to nominate your favourite IC; the chip you would save above all others, the one which got you started in electronics, or did great things with. The component which, if the call came from Radio 4, you would take to your desert island.

Our social media channels sizzled with selections. There was no outright winner - in fact, everyone chose a different chip. If anything it showed the rich history of the humble IC, their diverse applications and the affection they can inspire.  

This is what you spoke, tweeted and posted.

Rwanda: engineering change

Mariam helping a class with the kits
As a company which supplies resources to schools and universities, Rapid has always been happy to help charities and individuals doing educational work in the developing world. In recent years we have provided equipment and products for projects in countries such as Tanzania and South Sudan.

So we were delighted to support engineering masters graduate Mariam Olayiwola, who is spending six months as a volunteer in Rwandan schools. Her placement has been organized in collaboration with management consultants Newton, the charity Engineers Without Borders and Great Lakes Energy, a company which provides a network of sustainable solar energy solutions across the central African country.

The objective of the project was to give schoolchildren access to the kind of resources pupils in the UK take for granted. Schools in Rwanda can only afford basic essentials, meaning that science and maths lessons rarely rise above the level of "chalk and talk" exercises. As a result the ability of Rwanda’s most gifted pupils to work as engineers when they leave school is being eroded because of their lack of hands-on experience.

Mariam has been mentored by Newton employee Paul King, whose father Jeremy also runs STEM-based activities in schools. They both joined Mariam in Rwanda in January for a week of intensive teaching and training. The equipment provided by Rapid enabled Jeremy, Paul and Mariam to involve the schoolchildren in a range of practical activities such as building circuits, programming microcontrollers and activating switches. Two main kits were used, to demonstrate the principles of electronic control and solar engineering.

Paul & Jeremy King handing out equipment

It was the first time the children had been able to augment their studies with any kind of practical work.

The value of the project cannot be overestimated. As Jeremy King says: "At a specialist science and technology school I asked the question, ‘what happens when you pass electricity through a motor?’ It took me six minutes to get the correct answer. None of the students we worked with had ever made a circuit or made a buzzer work."

This is all the more remarkable since pupils at the Gashora Girls Academy of Science and Technology and Rwamagana Lutheran School were actually studying a university-level curriculum. 

Yet it was not long before the classrooms were alive with enthusiasm, learning and discovery, as pupils and teachers got to grips with the activities. "The students were transformed into engineers before our eyes”, said Mariam. “Working through problems, making mistakes, but most importantly enjoying and understanding what they were doing."


The feedback from students and teachers was overwhelmingly positive.

Comments from students included "the workshop was really interesting for me in a way that one didn't like engineering would end up liking it." "I thank you very much so may God reward you, but the time was not very much for me because the lesson was good. My question is that when will you be back for our next lesson. We loved you."

It is hoped that by sharing their new resources and skills, teachers in Rwanda will form hubs which can make fundamental changes to the way the sciences and maths is taught. The benefits are obvious for companies like Great Lakes Energy, which by employing home-grown engineers could expand its mission to bring clean energy to the country. Many villages rely on kerosene and other combustible fuels, which as well as being dangerous are proven to have an adverse affect on a population’s standard of living, health and education.

Jeremy hopes that another volunteer can be trained from Engineers Without Borders to continue the work after Mariam’s placement ends. UK schools with surplus equipment such as glue guns, battery holders and buzzers are welcome to contact Jeremy so that they can be sent to Rwanda.
