Might I jump in here too? I don't have an AC enabled RCX so I'm stuck with
battery power. But its not that terrible is it? I usually use rechargable
alkalines. And then I put in fresh batteries on game day. For project X the
energizer titaniums bought me an extra four seconds :)


Bruce pointed out that the way he builds, he does not use foresight and plan to have
easy access to his RCX.

I like to use more motors than is necessary, so I like the AC. as well, it allows a
person to use time, as a way to control things, without messing up performance.

under battery, drive for 10 seconds can change every run, but under AC drive for 10
seconds is always the same spot.


I think those guys are freaks from some other planet. Clearly they have access to
some sort of "super battery technology" that the rest of use can not access.

Well, I have used lithium batteries before. They give the full 9V unlike nickel
metal hydrides and seem to last forever. Also, they are much lighter than
regular batteries. The only downside is that they are super expensive.


that's is point #2, if you have the AC, and its not mission critical, then lets use it.




Anyway, I figure if people really want to use AC they can. I doubt tangling
wires will be an issue in this game since most people will just approach the box
from their side. I suppose not having batteries on board would make your robot
lighter which could make it a bit faster... But I doubt that would make a huge
difference. Maybe to be completely fair the AC powered RCX's should have
batteries in them anyway. Could be a nice backup in case of another power
failure... :)

I have batteries in all my bricks. you need it to maintain the firmware, when the plug
comes out.

(...) What a maroon! I only said that to help strengthen the case for AC. And yeah, you’d be nuts to have an RCX with no batteries in it...one blip and its no operating system and no program. And then the worst calamity of all...having Calum yelling (...) (21 years ago, 24-Aug-03, to lugnet.org.ca.rtltoronto)

(...) drive for 10 (...) I'd argue that you're using a bad design if a critical system on your machine is open-loop and relies on timing. You can't blame that on an unreliable power source - your machine should be able to operate reliably under all (...) (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)
