I need help here... and lots of advice.
My college (I'm an electronics lecturer now) has decided to take part in a STEM (scienc, technology, maths & engineering) even for local school kids in February to encourage them to get into technical careers, and make the right course choices early.
I will have groups of 16 students (~13/14 yrs of age) for 40 minutes (yep - you heard me right - only 40 minutes per group) and they have to do something electronic'y, with a target of 90% of them taking home something that works. There are three different groups per half day and it's across two days = 192 different students in total.
My gut instinct is to design a small circuit board with a pre-mounted AVR and get them to solder the leds or something, them program it with their own flashing led pattern, but I feel it's not quite there as an idea so I want my fellow 'freaks advice on this one - what should I think aout, what is feasible, what is easy...?
So far I've been able to haggle Â£5 per head - thats about $(US)8 each to make whatever I need to.
Any and all advice is gratefully appreciated guys... and don't hesitate to make suggestions or ask questions.
