Slotcar speed controller with display and electronic memory project

The more i think about this, the more i miss playing With Scalextric.

I Hadnt Thought Of Having The Chip In The Controller, I Had Always planned To Have the Chip In The car And Measure Some Type Of Double Tap On The Gas To activate The Boost.

I Assume Your Pwm Control Of mosfets Does The same Thing As The Variable Resistor In The original Controller? Thus Being Totally Compatible With A Normal Scalextric Set?
