Got a new car for the Scalextrics but it was not a digital ready one. Big disappointment as we got home. Anyway, got a digital chip and started installing it in the “not compatible” car. I had to workout the wiring which is very simple. It is a 4 pins plug, with 2 for the incoming signal from the track and 2 going to the motor and/or lights.
I decided to wire the lights directly to the track input so that they would always be “on” when the car is on the track.
I used some Sugru to put the electronic chip in the car and keep it stable. I absolutely love that stuff. It is really nice for fixing things like this and stays slightly flexible and bouncy. Ideal for this.
Finally I had to cut out the inside bits of the bodywork so that the electronics would fit. I used my dremel with a small disc to make precise cuts in the plastic.
Below, the wiring diagram setup and a couple of pictures of the process.
