 | | RCX and batteries
|
| Is the RCX considered a "high-drain" or "moderate-drain" device? If one is using the motors, I'd almost say yes, but how does frequency of use factor into this? Is anyone using rechargeable NiMH batteries in their RCX? What kind of performance to (...) (22 years ago, 24-Nov-02, to lugnet.robotics)

| Hi Guys , Just to let you know that the AC Power Adapter that LEGO supplies has an AC output voltage. You can even get 5mm plug and attach it to a 9V battery clip and use a standard 9V battery to power the RCX. It won't last long but it is a way to (...) (22 years ago, 25-Nov-02, to lugnet.robotics)

A 4-diode rectifier bridge converts AC to DC (and will sort out polarity problems), but it's not constant voltage DC (it's both halves of the AC sine wave above the (...)
