I use an external battery pack whenever possible/practical. It has 8 (not 6) NiMh cells, providing a total of 9.6 volts. Works fine. Actually, it produces a little more power than ordinary batteries. You need a socket for external power on the RCX (...) (25 years ago, 15-Jan-00, to lugnet.robotics.rcx)

(...) I prefer rechargeable alkalines myself (such as Rayovac Renewal). They have the same nominal cell voltage as alkalines, charge quickly, have excellent shelf life, and no memory effect. The downside is that their total charge is somewhat less (...) (25 years ago, 15-Jan-00, to lugnet.robotics.rcx)

As near as I can tell (sorry, not much of a Windows expert), the command line gets passed in its entirety to the executable, which then is responsible for parsing it into separate arguments.

(...) I just added the error check to nqc. I haven't changed the directory yet, though. Using the source directory was strictly from laziness. Assuming there aren't massive objections, I'll switch to using the current directory. Dave Baum (25 years ago, 15-Jan-00, to lugnet.robotics.rcx.nqc)

Greetings, I am yet another lucky person graced with an RIS this holiday season. I already seem doomed to buying more Lego sets for extra parts. I was quickly thwarted trying to build examples in Jonathan Knudsen's book which I assume is based on (...) (25 years ago, 14-Jan-00, to lugnet.robotics.rcx)

(...) Hmmm - the only reason I can think of for this would be if RcxCC is using one of the deprecated options that were removed in 2.1 (-o, -e, and -s which were replaced by -O, -E, and -S). If Mark can confirm which (if any) of these options are (...) (25 years ago, 14-Jan-00, to lugnet.robotics.rcx.nqc)

I think that's a really good idea. I tried it, and found out that the motor recieving power spins slower than the motor you spin. This is about 4:3. This could be a really good speed reduction technique that doesn't use gears, or you could power (...) (25 years ago, 13-Jan-00, to lugnet.robotics.rcx.nqc)
