Solar power supply
I broke all the rules — I soldered directly to the battery and I’m recharging an alkaline. I’m surely going to be sent to prison for this. The picture shows it charging a little bluetooth keyboard. It won’t charge my phone, the thing only produced 200mA or something like that. I’ll keep it in a sunny window. It might be handy occasionally.
