| i have a question concerning how the DCC signal is sent Is it just sort of a "rider" on top of the power similar to X-10 home automation signals?

| Hi there, Long time, no see - I've finally managed to dig out my Lego once again... First of all; I'm very pleased to see the outcome of LejOS 2.x - with Proximity, LLC, integration of rcxcomm, etc. Now, I was wondering if it would be possible (...)
