I have been wanting to know how slow my wussmachine is and I think I found a solution.
Tachometer made from a bicycle speedometer (cyclocomputer) - Instructables - DIY, How To, tech
This could also be used as a cheap tach instead o a fancy 300 dollar digitron.
basically you program a cheap digital bike speedometer to the size of your wheel and it will tell you the rpm which you then figure the mph.
Anyone else have a similar solution?
