Electric Screwdriver Hack

Original screwdriver runs with 4*1.5v non rechargeable cells. I modified the battery system with 5 rechargeable cells, So that we can get 6v to run the screwdriver perfectly. I also found difficulty in handling the screwdriver without handle. I thought to add handle at low cost and for easy handling. It costs half of the original rechargeable screwdriver (with handle).

This is my prototype made with plastic toy gun. This also worked well but not as strong as I desired.

• Electric screwdriver
