Hand cranked coffee grinder electric conversion

SummaryFirst of all, this is just a quick and dirty solution (the problem is simple, I'm too lazy to crank it by hand every morning), I will definitely upgrade it (making a motor housing to be quieter, hiding electronics), but using it with a drill was still an issue, as you needed to hold it.WARNING! Depending on your grind coarsness and the resistance of your grinder, different motor strength might be recommended. With further testing I noticed it struggles (and sometimes completely stops) when grinding espresso fine, So I will try it with different motors to find a reliable but fast enough solution. Until that, please keep in mind that the motor might not be powerful enough.USE WITH CAUTION, AT YOUR OWN RISK!It works with grinders that have an outer diameter of ~48 mm (+/- few mm is tolerable do to flexibility of mount), and pentagonal shaft, but feel free to modify it according to your needs. Also you need a motor (or modify the connecting shaft accordingly) like that. I used a 12V
