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
