Watch cleaner
About the Watch cleaner PCB
Watch cleaner is an open source ESP32 PCB design by DavidJ-Saving-Time, published on GitHub under the MIT license. It is a 2-layer board measuring 97.5 × 69 mm, with 14 components from 12 distinct parts.
Its main chip is the ESP32-DevKitC, from the ESP32 family. By type, the board carries 6 connectors, 3 resistors, 2 ICs and 1 transistor.
It belongs with the wearables designs in this gallery.
From the project
So this is a very rough draft of code designed to run on an esp32 to control a watch cleaning machine see this YouTube video https://youtu.be/Opr75n8DbYY I'll be adding to this and making it easier for people to use. Please feel free to pitch in

Watch cleaner: common questions
What microcontroller does the Watch cleaner use?
The Watch cleaner is built around the ESP32-DevKitC, from the ESP32 family.
How big is the Watch cleaner PCB?
The Watch cleaner measures 97.5 × 69 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Watch cleaner?
14 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Watch cleaner design files?
From the DavidJ-Saving-Time/watch-cleaner repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Watch cleaner design in my own project?
Yes, under the terms of its MIT license, which DavidJ-Saving-Time chose for the repository.
Can I test firmware for the Watch cleaner without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
