Wow, it's a little later in the year, and no additional posts have been made
on the subject (right?).
I just want to add, that connecting a 6 or 9.6 Volt DC via alligator clips
hasn't yielded any reaction from the RCX (not even with the polarity
reversed). Luckily it still worked after these experiments...
I now want to try it with a 12 V (1.25 Amps) AC/DC converter, but I'm
convinced that alligator clips aren't going to be a durable solution.
So, does anybody have any tips on creating a dummy powerpack the shape of a
1.5 V battery? I'm looking into using a magic marker of some sort. I have
created a dummy 9 Volts brick for the IR tower using Lego bricks!!! And it
works like a charm too at 6 Volts (and nearly 2 A).
So long for now, gotta hit da beach damorra!
