Hey /g I'm trying to design a bike generator so I can charge my phone for Pokemon go, originally I was just going to use a diode to connect the battery and generator but then I started thinking about overcharge and knowing how much power I have. I was wondering if I could use a relay as a diode and I searched around but a lot of places say it's bad because of battery arcing however since the relay is never between the battery terminals should I be ok using it in place of a diode? My thinking is I'll have several different zener diodes and leds to make a standard power gauge and the highest resistance diode will be connected to the relay so at full battery it cuts off the the generator from the battery, my other concern is at max power the relay will be constantly switching, will it be ok long term?
wouldnt it be better to get one of those RC car batteries, ducktap it to the pike buy parts to make a converter/adater for a usb hub, and put an enclosure around all that?

I'm sorta doing that, I'm using one of those batteries for those plastic cars kids ride in and I'm using a lighter port power inverter that has a standard wall socket and usb port

If you were charging a battery by itself you'd have to worry about overcharging, but the phone already has that circuitry built into it. Give it 5v and it will charge the battery and stop when it's full. What you need is a 5v regulator to keep the voltage from going too high.

Yeah but the generator flows into the battery only one way then the battery stores the power so the battery could oc

reporting you to the fbi just for kicks
can't wait to see the anon post of some idiot who brought a homebuilt electric bike to a race rally and beatup by the cops bcus it was confused as being a bomb

Gut a USB car charger and give that 12v.

Is this game the best thing to happen to society in the last 10 years?
Get a dynamo for your bike, an step up or step down IC (depending on dynamo output) look at the Datasheet of IC and configure it to give you 5 Volt, connect the 5v to phone.
Better: put 5v into a power bank and simultaneously charge phone with powerbank, with this setup you have a puffer

Undoing the damage that previous games caused when they weren't high tech enough.
