The Lüliang flow meter casing, powered by a lithium battery,
has been improved based on the following:
1. A mezzanine PCB has been added
. 2. An ultra-thin encoder has been installed
. 3. A TP4056 lithium battery charging and discharging integrated module has been added, powered by the lithium battery.
4. A lithium battery switch has been added.
5. An AB casing has been installed, with a 1.5mm PCB with a window .
* Ultra-thin design, mezzanine output
. Copying is welcome.
* 1.5mm PCB, cut by yourself

IP5306_18650 Simple Power Bank
IP5306
The IP5306 simple power bank
pictured does not have a button switch.
Version 1.0 shown in the picture can be used with 5V 1A; however, using a 5V 2A charger for charging and discharging will cause excessive current at pin 7, resulting in a blown fuse. This issue has been fixed in version 1.1.

JLCPCB offline programmer
Offline programmer
This is a two-in-one offline programmer design that combines two different boards into one, enabling online programming, offline programming, and power supply functions. (Previously, only the LEDs and programming output were soldered, not the power output, which caused problems downloading the program. All components need to be soldered; the layout will be changed later.)

Handheld high-powered hair dryer with speed controller and breathing status indicator light.
Upgraded version of the handheld high-powered hair dryer, open
source license: CC BY-NC-SA 3.0 (Unauthorized reproduction prohibited).
Please follow the CC-BY-NC-SA 3.0 open-source license. This project is for learning and research purposes only and is prohibited for commercial use.
Based on Xiaoyu's handheld high-powered hair dryer MAX push-button speed controller, this project modifies
and adds a breathing light function (breathing light in standby mode, switching to high brightness when the high-powered fan is activated).
The circuit uses a common flashlight constant current driver chip: AMC7135, which has a 350mA constant current capability and is powered by the BEC output of the brushless ESC.
The circuit board shown on the cover is for debugging purposes (given the current parameters of the LEDs purchased from Taobao, I only soldered one).
The LED board has also been redesigned, consisting of 36 0603 ice blue LEDs connected in parallel.
Please see the attached video for the actual effect.
