AC Drill Speed Controller

Due to high RPM of drilling machine,sometimes drill bit will be damaged. To avoid this problem I made this speed controller. We can use this for any type of AC motor's, saw's, fan etc... and also as light intensity controller.

• Gang box
• AC socket
• AC wire

• Voltage Regulator Dimming Module

• Drill two holes in the gang box. One for AC wire and another for dimmer controller.
• Insert the dimmer in one of the hole and fix it.
• Fix the AC socket.

Wire according to the picture above

Make a Label and attach it.. It's finished.
