I decided to create my own rechargeable electric screwdriver as I did not like the existing models on the internet or in stores. This one features a battery protection circuit, sliding actuator, a 4.4Wh battery, and a 1:200 reductor motor. It lasts a really long time and is capable of some serious power.
The wiring schematic can be seen in the pictures.
Components required:
- GA12-N20 micro motor with 1:200 reductor
- 18350 Li-ion battery (unprotected: due to size constraints)
- 03962A battery charging board w/ micro-USB connector
- 2 microswitches
- 2 battery spring contacts
- 1 meter of 20 gauge wire (red & black)
- 2 countersunk M3x6 screws
- 1 4x1.5mm round magnet (fixed to the inside of the bit w/ cyanoacrylate glue)
