I either had all of the parts or was able to scrounge them for free, so the whole project cost me nothing. It requires basic soldering and welding skills, but no fancy circuitry knowledge is needed.
- old washing machine motor
- old bicycle
- bridge rectifier
- old UPS and battery
- 20ga wire
- angle iron
- cheap multimeter
- soldering setup
- welding setup
- angle grinder with cutoff wheels
Step 1: Sourcing Parts
a helpful resource for identifying types of washers
how to tell what kind of motor you have
how to get the motor out of the washing machine. Note: I didn't remove the shaft or seals/bearings from the drum, I just cut out the section of the drum that housed the shaft assembly. See 1st photo.
The bike frame I picked up for free at the Green Bike Trust.
The UPS and batteries I got for free from my local computer repair shop. It is often cheaper for companies to buy a whole new UPS rather than replace dead batteries, so old ones can usually be found in abundance. This is how to rejuvenate old UPS batteries.
The bridge rectifier I pulled out of an old car alternator I had lying around.
