 | | RCX.pm questions
|
| So, I've finally found a little bit of time to play with RCX.pm, and it is pretty cool. However, I'm having lots of problems convincing the RCX to actually do things :) it appears that in many cases, the first signal sent to the RCX is always (...) (24 years ago, 6-Nov-00, to lugnet.robotics.rcx)

| | Re: Batteries...
|
| Yes, it's possible. You get less voltage with NiCads, so the motors don't turn as fast as they do with brand-new alkalines. Plus they don't last as long. However, they're so much cheaper to run! I used to use NiCads during development and general (...) (24 years ago, 15-Nov-00, to lugnet.robotics.rcx)

| | RE: IR Problems
|
| RCX IR does not require direct line of sight. All sorts of reflections will work. Especially if you're in a "smallish" (bedroom, home office) room. The RCX firmware always has the IR turned off. "Wait for mail" and "send mail" is just a higher (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)
