| I have an old 'wall wart' lying around. It has a rating of (12 vdc 1 amp output). i was wondering if i can use it on the handy board. the specs i read about the handy board call for a 12v 500mAmp output. any response would be appreciated.

| (...) In short, No. The charging cicuitry on the HB (especially the zap mode) is designed for a 500ma supply. People have had problems with 1 amp ones. Best, Duncan (25 years ago, 9-May-99, to lugnet.robotics.handyboard)

| (...) I'm relying on non-handyboard experience here, but I'm going to assume that's too much. One amp is a heavy load, and although there's a 5v regulator on the circuit, I'd guess that it's not rated for 1 amp (it may just run hot) and might not be (...)

| Hi all: The problem with using a wall wart that is NOT 12 V @ 500 mA is this: most wall warts are _not_ regulated, and they have a fairly high internal impedance. If there is no load on a "12 V" unit, the output voltage will likely be at least 18 V, (...) (25 years ago, 10-May-99, to lugnet.robotics.handyboard)
