Electronic Project

Science syllabus fun for the junior boffin

Electronic Project Science Fair200 in one! 150 in one! The not very catchy 65 in one! And 50 in one! The oscillator-obsessed cousin to the generic chemistry set, Electronic Project (a product from the on-its-sleeve-for-nerdiness named Science Fair) was a big box full of circuits, cables and dials that boasted anything from 50 to 200 possible projects for you to build, depending on how much cash mum and dad were willing to shell out.

In the 150 in one kit, there was mucho fun to be had from a 7-segment LED display and an advanced integrated circuit. And when you factor in some of Science Fair’s other products - such as the build your own Solar Power Lab and, better than that, The Lie Detector Kit (sporting a box depicting an under-pressure dad surrounded by his suspicious family) – then surely some wholesome Weird Science-type experimentation was but a crocodile-clip away?

Sadly, no. As the blurb on Salter Science’s Introduction To Electronics lid hinted (“Make a radio, police siren, morse code and more!”), most of the experiments were pretty samey. And sound-wavey. Plus, there wasn’t even a soldering iron in it. How infuriatingly safety-conscious! It takes a special kind of enthusiasm to get excited by transistors, resistors, and capacitors that connect with pre-cut wires and already-assembled spring coils. And we’ll put good money on that those kids’ hobbies later included CB radio and the early home computers. Naturally, what every other child in the land was hoping to build was some kind of infra-red CCTV-style early warning system for their bedroom1. Not easy to do with raw materials that allowed only for you to make a series of enthralling logic gates.

1Girls were understandably protective of their privacy as they entered adolescence, what with “the curse” and all that. The boys were usually trying to work out a way to watch that borrowed Electric Blue video without being caught.

I used long green wires attached to the red and black terminals of my 100 in one project kit to rig up a 'burgular alarm' with a view to stopping the cat crapping on the hall carpet - it worked like a charm until she realised that it needed a manual re-set to silence the 100 decibel whine.

The cunning minx used to sit on 'sensor' whenever she wanted some attention - after (too) many early morning wake up calls, it and the cat were banned from the hall - so in a way it kind of worked.

These things gave one delusions of grandeur. Stick a few wires together to form a morse code emitter (ie. press the button and it goes beep), add a bit of waffle about NAND gates and and suddenly you considered yourself an electronics expert.

It was of course possible to damage it irreversibly. I burnt out the LED's on mine by overloading them with too much voltage. Well, all scientists are expected to experiment, aren't they?

Most interestingly in the '50 In One' kit that I had was a radio transmitter, which although was legal in America, was illegal in England. By running a long wire from my bedroom window down to the clothes line pole I was able to use my '50 in One' to transmit 'Radio Clive' to the end of the road, most likely screwing up everyones TV reception in the process.
