Just a follow up to this topic now that I have an RCX of my own (thanks Santa...and my wife) I found that using the Radio Shack light sensors for detecting on coming trains to the crossing works great. No special wiring needed at all, I basicly (...) (25 years ago, 2-Jan-01, to lugnet.trains, lugnet.robotics)

I have a power supply that gives 9.3 volts and can give 130mA. Just 3 questions - 1) Presumably the RCX can take 9.3 volts? It's not much over 9V... (Sound of frying RCX) 2) 130mA. Is that enough? I'm not sure how the RCX works internally, but the (...) (25 years ago, 2-Jan-01, to lugnet.robotics)
