We were asked to build another pedal powered Scalextric for a promotions company.
Here are some photos of the build and the final unit – no photos of it in action yet, but hopefully updated soon.
Testing the unit was always fun. the final item was fully branded by the client.
Simple figure-8 4 lane track which breaks down into 2m x 1m pices for loading into a standard van. 
Control box fusing and outputs.
Control box inputs. 
Control box insides – excess power needs to be dumped in some power resistors.
The track was clipped down onto the board.
