| | | Hello Ilja, (...) Here is the method that I used in my motors tests ((URL) that require no modification to RCX: use two fake batteries assembled from the sawed ends of old alkaline batteries, maintained at the right spacing with rods of hot melting (...)

Please forgive me that I know next to nothing about electric power and electronics -- or so it seems. - Your regulated (...) (21 years ago, 12-Jan-04, to lugnet.robotics)

| | | | | Hi Ken, (...) Maximum RCX power consumption is 1500 mA (there is a fuse inside rated 1.5A). Anything rated at least 1A should be OK. (...) They should, if they are really regulated (some cheap warts advertised as regulated are not so good...). A (...) (21 years ago, 12-Jan-04, to lugnet.robotics)

| | | | | | | (...) CAUTION!!! The wall-wart that comes with the train adaptor puts out an AC voltage that will likely damage your RCX if used this way!!! I have read reports of people burning out their RCXes by connecting the wall-wart to the battery contacts (...) (21 years ago, 12-Jan-04, to lugnet.robotics)

| | | | | | | | (...) You are right Chris, the train controller is not a good idea. Indeed all Lego adaptors (including the one for RCX 1.0) provide AC only. And turning the knob in the wrong direction is just too easy. Thanks for correcting my misleading (...) (21 years ago, 12-Jan-04, to lugnet.robotics)

| | | | | | (...) Right. But that's not what I was asking or suggesting. The idea was...elave the RCX2.0 as is on batteries. Run some other devices off of whatever power source, but control that power source via program logic from the RCX. The RCX could run (...) (21 years ago, 20-Jan-04, to lugnet.robotics)

All final output devices (lights, motors, etc.) are powered by switched 9v AC supplies, and the (...) (21 years ago, 20-Jan-04, to lugnet.robotics)
