I was wonderin if anyone has a 20 ohm "trimmer" pot. This is the same one used in the potentiometer mod in Bit Science. The shipping at allelectronics.com is outrageous!!!
I can get you TWO shipped for $2.50 USD. They are not exactly the same (ie: they look different) but I've used them for the infinite POT mod with no problems. (finally brought my dual cell bit down to controlable speeds!!)
