I’m looking make a motor adapter for my hand coffee grinder.
Obviously I know there’s electric grinders already but I fancy the project and like the idea of one grinder for both.
I’ve sourced a good motor and I’m pretty happy with the assembly but I would like to have an auto shut off feature.
While under load you can hear the motor putting in work so I’m sure there’s a significant current spike.
Then once all the beans have passed through the grinder the motor returns to it’s no load sound/draw.
My question is, is there a relay out there that I can set to switch off once the motors current draw drops?
the motor is a 3.6v hand screwdriver powered off of what looks like a single 18650 lithium cell listed at 2Ah
I have a roundabout knowledge of electronics but nothing all that impressive.
Any help would be appreciated.
Kind Regards
Tyler
