Hi Trevyn, From the photo you posted, it appears that you have the input and output pins of the 7805 reversed. According to the datasheet, this will probably fry the regulator. I'd recommend getting a new part before continuing, so as not to risk (...) (23 years ago, 2-Feb-02, to lugnet.robotics.rcx)

Most "wall wart" transformers give about 3-5 volts above what is marked on them. I would not use one of these directly. However, I am currently working on using a 7809 voltage regulator. If you don't know, a voltage regulator is a small electronic (...) (23 years ago, 1-Feb-02, to lugnet.robotics.rcx)

You cannot program them independantly, but you can make sure your programs respond to different IR messages during normal operation. All RCX's will receive the messages, but as long as only one responds with some action then independant control is (...) (23 years ago, 22-Jan-02, to lugnet.robotics.rcx, lugnet.robotics)
