Really? It's just a normal sized mobile phone charger that I found in a colleague's desk that I rifled through after he had left the company. (-: And that was quite a while after he left, like some months! This is in Europe, in Germany. I know in the US, you have to get to the guys desk first thing the next morning, early, and even then you're only lucky to find some paper clips.

Wow. If it's 5.1 volts unloaded, then maybe it is regulated. Do you have a scope to see what kind of ripple you have? I think you said that it was rated for 1.7A. That's a pretty hefty wall wart. You might try loading it with a resistor and see whether the voltage stays in the 5 volt neighborhood. Keep in mind the power ... it's pretty easy to make those 1/8th watters light up. --McD -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
