A 250-amp Speed Controller for RC cars

Detailed workshops and maintenance yards can be the highlight of many model railways or dioramas. Unfortunately they usually suffer from one common problem. They are static. At the scale involved, it is not an easy problem to overcome either. Moving parts at this size present quite a challenge.

Every model railway has a place where road and rail meet, and when it does, some form of warning is needed. Flashing lights work well, but something is needed to drive them. And that is where this circuit comes in. All it does is flash lights and it is so simple anyone could build it!
