(...) The RCX uses AC input, not DC. The AC/DC conversion is internal, so what you need is a power adapter that outputs AC. I've heard that you can toast your RCX with an AC/DC adapter as well, so be careful. (24 years ago, 31-Mar-01, to lugnet.robotics)

(...) Is that right? Wouldn't the AC adapter be a AC to DC Converter? I have seen the RCX circuit board and I do not remember there being enough room for a transformer built-in to convert the AC signal to DC. Steven B. Combs, MS, CIT Associate (...) (24 years ago, 31-Mar-01, to lugnet.robotics)

(...) The RCX accepts AC voltage, all it needs to convert to DC is 4 diodes, or a small bridge rectifier. It takes anything from 9-12VAC. Apparently you can do some damage by plugging in DC, as in the long term you will only be passing voltage (...) (24 years ago, 31-Mar-01, to lugnet.robotics)
