Some people already discussed it in the past but I don't remember nobody
saying that it was already done. I'm very interested in this matter also.
One idea was do use a wire with aligator clips connected to the internal
baterry connectors. You may need to cut the RCX box a little to leave space
for the wire. The other end could be connected to a female jack so that you
could connect an 9V AC adapter or a an external battery pack like the 9.6V
NiCd pack used in RC toys.
My main concerns are related to voltage variation. The external outlet at
RCX 1.0 accepted an input from 9-12V, so it had probably a kind of voltage
regulator internally. The battery case probably don't have such regulator.
If you use a 9.6V NiCd pack, a single diode in series would reduce the
voltage to 8.9-9V, which is acceptable.
But if you use an AC adacpter, you should use a very good one that outputs
exatly 9V. Most AC adapters aren't so reliable so you must take care. Yo may
need some aditional circuit. Would a 9V zener diode solve the problem?
Tips anyone?

| You could use a voltage regulator at the adaptor output. You would not get anything above the rated voltage, but I do not know about lower voltages. Andy (...) (24 years ago, 29-Dec-00, to lugnet.robotics)

| (...) Since it works fine with 1.2V recharable batteries I guess a little less then 9V is also OK. Also it should handle a tad above 9V w/o problems. I got a very nice transformator with both an analouge voltage and ampere meter but I'll hook it up (...) (24 years ago, 2-Jan-01, to lugnet.robotics)
