I'll just go one further here and suggest that with an old (ball) mouse you 
already have a speedometer. Crack it open and drive one of the axis wheels 
with part of the bicycle wheel. You may need to do some gearing to get the 
angular velocity in the same range as the mouse was designed to read. The 
mouse will tell you what angle it has gone through per sample and from that 
you can determine its angular velocity.
