Foot Pedal Pcb Drill Press

a very useful pcb driil press with foot pedal

i use 3 555 timers to adjust up,down and drill speed

i use expesspcb, its a free and easy program to make pcb's

the mosfets are from an old PC motherboard

i use items from old printers. you can use better meterials!

the motor for up-down movement, must be geared for easiest control

the drill is a cheap 12v dremmel

make the drill start automatically when it reach the pcb

i use a terminal switch at back place of the drill's motor

make the up/down movement stop automatically

connect all the cables..

the power supply is 12v, at least 2A

i make a simple foot pedal with a button switch.
