YBA-AMS

Overview

CH connects to the motor; the pin marked with a down arrow (⬇) connects to the bottom of the motor.
SW connects to the common and middle pins of the microswitch; U is the top pin, D is the bottom pin, pin distinction is not important.
M connects to the manual switch; + is for feeding, - is for unloading. When using
the DRV8833 motor drive module with the bottom facing up and
powered by the microcontroller's 5V interface, the bottom 5V-VCC needs to be shorted. In this case, there is no need to solder the step-down module to the DC socket.

All connectors are 2.54mm; you can choose according to your personal preference

NE555_12V Dual-color LED Strip Driver

I have too many NE555s on hand, I'll find a project to use some of them.

The schematic for this project comes from @画板当吃生菜's "Analog Circuit: Dormitory Lamp Switch Dimming Circuit". I added a 12V trigger circuit to the original project, which can request 12V voltage from charging heads that support the PD protocol. Because a 6-pin Type-C interface is used, this project can only activate the 12V using a double-ended Type-C data cable.
The casing comes from the open-source hackledpro from HACK Labs.

Copying the ESP32 sepak takraw light setup: main control board plus light board

This project, which involves copying existing work, is already in its third iteration and hasn't been validated yet. Be extremely cautious when replicating! Be extremely cautious when replicating! Be extremely cautious when replicating!

This is a project I copied, and it's the third version of the solution, still untested. Be careful when replicating! Be careful when replicating! Be careful when replicating!

Reference projects: 1. Espressif - Voice-activated Vine Ball Lamp Project 2. Full-color RGB Smart Fill Light - Warm and Cool Light Adjustment.

Since there was no outer casing, I used LaserMaker to draw the casing design and made a casing from laser-cut wood. The result looks pretty good. I'll share the casing design file here.
The casing still has many unreasonable aspects (mainly the size of the USB port and the screw holes), so be careful when replicating!
