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.

    • 6 mm MDF
    • 4 mm MDF
    • Wood glue

    Tools needed:

    • Jigsaw
    • Drill machine
    • Soldering iron
    • Screwdriver

    Step 3: Design and Cutting

    • Cut 3 pieces of template 1 from 6mm MDF.
    • Cut 2 pieces of template 2 from 4mm MDF.
    • Glue 6mm MDF's.

    Step 4: Cutting Grooves

    Cut grooves as shown in picture so that the battery, switches to be fitted.

    Step 5: Drilling Holes for Wiring

    Step 11: Making the Stand

    Cut 2 wood pieces for making stand as shown.

    Step 12: Final Step

    I filled the gaps by mixing wood dust and glue. Finally paint it.

    Awesome build
