A couple questions for someone with a multimeter:
Does the 1.0 power adapter output a clean 9v DC? Or does it overcompensate --
at, say, 9.3v -- like other cheap wall adapters? Does the voltage drop by
more than 1% while powering a couple motors? Does the output voltage depend
on your wall voltage (e.g., 110v/115v/120v) or does the adapter contain a
power regulator circuit outputting a known voltage regardless of the accuracy
of the input voltage?
How many mA can a cicruit external to the RCX safely draw through the RCX at
9v? Is the RCX capable of modulating voltage directly or does it use
exclusively pulse-width modulation?
Thanks,
--Todd
