There must be plenty of people around who have thought about doing this, but Martin Raynsford has beat us to it as he has built an Arduino controlled version of the coolest arcade game, Donkey Kong. Using ball bearings instead of those rolling barrels, the player has to guide the man up the course ensuring that he is not hit by any; they are magnetic so there is no cheating on this game!
This is how the real world Donkey Kong came into existence;
Built as part of a larger project this was my first attempt at a mechanical version of Donkey Kong. Time constraints meant I had to drop the XY CNC controller but hopefully explains why this is only V1. All the construction files and details can be found on my website MSRaynsford.co.uk
