GOAL: Power a 2x AAA battery powered headset with a USB port
METHOD: 3x diode in series
RESULT: Failure
Detailed Methods:
Connected three diodes head to foot. Connected USB 2.0 (side with USB to computer) red wire to 1st diode @ the opposite side of the band. Connected an empty red wire to 4th diode (also tried 3 diodes with no change in success). Connected black ground wires. Connected wires to headset (first red to positive battery terminal wire, then switched). None of these allowed the device to power on when USB was plugged into computer. Using a voltameter, I found there was a circuit when USB plugged into computer. For whatever reason, in DC mV I saw a 200 mV signal. Please help, Thanks
