Tachometer for Huky300
Bicycle tachometer modified to fit and measure drum rotation rpm. This is done in anticipation of future motor replacement (of a higher rpm unit) and addition of variable speed control. Goal is to have drum rotation as part of the profiling, in additional to gas and air settings.
I replaced the stock 20vdc adaptor with a 24vdc unit, which "restores" the stock motor to it's default speed. The "as-purchased" configuration down-rated the motor (reason unknown). Drum rotation increased from 44rpm to 52rpm.
Trial runs already showed differences in the profile. At first glance, roasts seemed to be much more even at the higher drum speed. How it affect the cup will be determined in the coming weeks...
