Homebrew PCBs

If you want to make your drill a real varible speed drill try this.
Get you hand on a table model sewing machine foot padel. This way you 
can bring the drill bit to the place where you want to make the hole 
then lightly press ...you won't slide off so much this way. Your drill 
is a 0 - whatever rpms now, works great with my Dremil.

A Dremel MultiPro has a speed control built in. It will not run
off some speed control units unless you put a small lightbulb across
the Dremel. Older Dremel models will work with a second speed
controller. I use a 6 watt candelabra bulb inside my computer
controlled speed unit.

Ok, then mine(Dremel Drill) is maybe 12-15 yrs old and the foot pedal 
is even older. I guess I just got lucky.

I just used a Foredom foot controller with an old Dremel and a
newer MultiPro. Both are very choppy and only work when the footpeddle
is all the way down. Add the lightbulb and you get smooth full range.
Turn the Dremel to halfspeed and you get a slower range. The lightbulb
develops the voltage the Triac in the footswitch needs to operate
correctly. A resistor would also work across the Dremel. I used a
Christmas type lightbulb in a candelabra replacement socket. You might
have a reostate type foot peddle which uses Nichrome wire to drop the
voltage. You got lucky!
