Hello all,
I have a few cheap circuits I would like to make:
The first is a 5V to 12V step-up converter; I found one here... This one should be easy enough, and I only need about 2W max. power from it. The power input is 5V 890mA from a phone wall ps.
Using the same "charger", I would like to make a cheap, simple circuit that can detect when a 3.7V Li-ion battery is charged and hence stop charging at that point. These seem very interesting. Which one would you recommend?
