This is the first open source spinner for generic ultrasonic cleaners.

The main purpose it to clean records as deeply as possible.
It's the first design to actually let the cavitation work by pausing the motor on different time intervals.

It has four different cleaning modes:
 * 0. Stopped
 * 1. Move 10degrees every 66 seconds, rotating the disc 181,8 degrees after 20 minutes
 * 2. Move 10degrees every 33 seconds, rotating the disc 181,8 degrees after 10 minutes
 * 3. Move 10degrees every 16 seconds, rotating the disc 187,5 degrees after 5 minutes
 * 4. Move at 2RPM

In order to complete the project you will need:
* 6 liters ultrasonic cleaner
* ATTiny85 microcontroler
* A push button (normally open)
* A led
* Three resistors: 430, 1K and 10k
* 28BYJ-48 stepper driver, modded to be bipolar
* L9110S DC motor driver
* 5V from a power supply
* 6mm linear shaft (as long as your cleaner width)
* 608zz bearing
* Eletronics knowledge (to copy the schematics from KiCad)
* A 3D printer
* A LOT of patience


Check the pictures to understand the pieces you need.
There are a few variations to the kind of washing machine you own. So make sure you print the right support.
There is no need to actually create a printed PCB, but I supplied a complete KiCAD project in case you want to.
