Hey folks, Has anyone been able to use a Thinkpad IR Port to talk to the RCX? I have been programming the RCX using spirit.ocx. All is well with the IR Tower connected to a serial port. I would like to get rid of the IR tower and use the built-in IR (...) (25 years ago, 2-Jan-01, to lugnet.robotics)

The new Mindstorms RIS 1.5 set I gave my son for Christmas had a bad motor right out of the box. The motor is just jammed up and will barely turn by hand. I emailed Lego and they are sending me a new one (in up to 3 weeks!). We couldn't wait to get (...) (25 years ago, 2-Jan-01, to 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)
