Hello all. The mirror trick works for sending the signals from the IR tower to the RCX (I'm only using a single RCX). However, the return signal the RCX wants to send to the tower isn't transmitted across the mirror. Since you mentioned leJOS and (...) (19 years ago, 8-Aug-05, to lugnet.robotics.rcx)

Orient both RCXs so that they are pointing towards the ceiling. Set the RCX transmit power level to high (default is probably low power); there's probably some Lejos function to do this -- all it requires is setting one bit in an I/O register to 1. (...)

Greetings helpful companions. Now that I've buttered you up, let's move on... I've built a robotic arm using my RCX 1.0 brick. I'm controlling it via my computer with LeJOS (not important, I think).
