: Hi ,
: I dont understand why are you Using the Most out dated infrared technology...which most of the time requires relays ....Instead try using a Ultrasonic Module..Placing a small Reciver on the train Engine with the Body grounded as the Antenna...one can Trigger Signals Via AIR...through a Simple TOY CAR REMOTE CONTROLL...
: ........Try this Out.....

Thanks for the suggestion. Are you saying that toy remote controls use ultrasound? I thought they used RF. It had occurred to me to buy a cheap RC toy car and tear the electronics out of it, but I wanted to learn something in the process. In any case, can you suggest an inexpensive source for ultrasound and/or RF circuits? Thanks, Dan
