RE: Adapting cell battery to HP 41
Hi,
Here the code of boards I used for this project. They are used in Arduino projects and easily found in market. 03962A battery charger - this one has separeted outputs for battery and to the circuit to be energized; MT3608A step-up converter You can put such names on Ebay and it will bring tons of sellers. I just have one doubt about my project: what will happen when battery discharge too much... Best wishes! ARTUR MARIO JUNIOR BRAZIL |
