Making a touch sensor.

Post by dsjove »

I have recently created a way for my Power Function train to recharge its battery via the train buffer. I simply had to buy matching DC power plugs, a bridge rectifier, and metal contacts. Now I would like to turn the end-of-line train-buffer-stop into a touch sensor. When the train is charging the sensor is to be in a true state.

We have 10V 700ma coming out of the PF power adaptor. Where do I buy a female Nxt sensor port? I imagine the circuitry would be very simple. Where do I go to find what I need to do?

I ended up splicing an old RCX cable, adding a small relay, and a ~310ohm resister. That was enough to simulate a touch sensor.
