Stir the Soup, Baby
Some recipes say: ‘Knead the dough for half an hour’ or ‘Stir the soup for 20 minutes’. What? Really? I don't have that much time! Can't someone else do it?
Yes, someone can.
Supplies
3D printed parts (Alternatively, a wooden wheel and holding arm can of course also be used!)
5V motor + power supply (power bank & old USB cable)
1 screw M4 20mm
1 screw M6
wooden board as base
and of course a wooden spoon!
The Gears + Base
The drive is similar to that of an old steam locomotive, but converts a rotary movement into a linear, slightly circular movement by means of a lever arm.
We have to mount on the board: Motor, drive wheel, screw as axle. A holder for the cable from step 3 would be useful.
We use a clothes peg to attach it to the cooking pot.
The Arm
The arm serves as a holder and movement rail for our wooden spoon. The screw nut of the holder must be fixed with superglue and the screw itself is first fixed in the rotary knob.
Alternatively, a wooden wheel and holding arm can of course also be used!
Power Supply
The motor is designed for 5V. A power supply of 3-6 volts should not be a problem. Solder the cable to the motor, connect the battery, maybe a switch in between - done.
I'm using an old USB cable with a broken USB-B plug. Cut it off, remove the insulation and solder it on. I can then use any power bank as a power source,
Go, Stir It, Baby
What a well-stirred soup! Hmmm!.
