Hello, I'm building a DC-DC boost converter, it's called the Mintyboost - here is the link:
Minty Boost! - USB charger for your gadgets
It takes 2 AA batteries and boosts them to 5V so you can charge USB devices.
I'm going to use NIMH rechargeable batteries, so in order to avoid over-discharging my batteries, I need to make the device shut off when the batteries are below a certain level. I was thinking ~2.2V.
What would be the least power-consuming way to do this? Or the best way, or any thoughts you have on this...?
