Introduction: 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).
