My Wind-Triggered Lantern! Bit late, I know, but trying to catch up on a few projects. Instead of putting the LED on the outside, I put it inside for weather-proofing and it makes it seem a lot brighter. #makercamp

I have built the bicycle powered phone charger, and thoroughly tested all connections and voltage coming out at the end of the circuit (about 2.5 volts). My phone does not register as charging though, so my final thought was that it is probably charging, but it does not register on the device because the voltage is too low. What is the voltage required to have a phone such as the HTC Desire C register that it is charging?

It's probably not charging at all, voltage not high enough.
