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.
