QQ Group: 754881030
Based on STC microcontroller, this is a multi-functional controller for vehicle lights, door locks, etc.
Update Log:
2024/03/13 First Release (Firmware and supporting components uploaded)
Electrical Parameters :
Maximum Operating Voltage ≤ 30V DC
Maximum Load Current 5A
Action Response ≤ 10ms
Function Details:
1. Brake lights flash 3 times quickly after braking, then remain on
. 2. Rear fog lights synchronize with the above function
. 3. The above function is disabled after the fog lights are turned on, maintaining the original warning function.
4. Can be linked to control other vehicle equipment or functions; explore on your own.
Notes:
Requires some hands-on ability. Suitable
for those interested in vehicle modification . Open

USB Multi-functional Cement Loader
This is a USB cement loader, but it's multifunctional!
This is a cement load, but more than just a cement load!!!
Project origin:
I made a charging module (PS: SW3518S in my project), and I wanted to test the charging ripple of my module. However, as we all know, whether it's a mobile phone or a computer, the power, current, and voltage change over time during charging, and the timing of these changes varies depending on the device's charging strategy. This makes it difficult to control the variables during testing, so I DIYed a load using a cement resistor.
Highlights:
1. Straight-through mode ➡️
A single cement load is a bit...

Electronic Entertainment - Printed JLC89C52RC Microcontroller
I participated in an electronic quiz show
, a project that involved printing microcontrollers onto a PCB board—it was far ahead of its time!
I have a dream...
to
print ICs directly onto the PCB
, just like color silkscreen printing!
--------------------------------------------------------。
So I found JLC, and amazingly, JLC actually had this technology (just kidding!), and even gave me a free sample!
Finally, the color silkscreened 8051 was born! This is a great technology, allowing microcontroller chips to be printed directly onto the PCB, very nice!
-------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------
The above is purely for fun~~~~~~~~~~~~~~~~
There's an STC microcontroller on the back----hahaha
Happy April Fool's Day~
But~~~ what if it actually comes true someday!
There's some text above, please read carefully.

Simple Digital Oscilloscope
Simple Oscilloscope
This is a simple oscilloscope practice project from the LCSC training camp.
This project has a few issues and is for reference only. Please do not use it directly.
The core board is from https://oshwhub.com/micespring/stm32h750vb-CoreBoard_copy. It uses a few components that you may have on hand. Please refer directly to the original project for more information.
This extended version is based on the Hardwood Classroom oscilloscope expansion board (https://oshwhub.com/damihuang/AFE03).
The screen uses an ili9341 screen module. Modifying the initialization code in the example program allows it to light up.
It has been prototyped and soldered for verification. A few issues exist, listed below for reference only
: 1. The screen uses an SPI3, but the PB3 pin does not light up. It lights up when connected via a jumper wire from PC10. Due to limited resources, the cause is unknown
. 2. One less 5V LDO was used compared to the standard range, resulting in slight interference.
3. During self-testing, the errors for square waves, triangle waves, and sine waves are relatively large. It's unclear whether this is due to improper soldering or interference from the above reasons. Further investigation is needed (the cause has been found).
I plan to release this project today. Before releasing, I wanted to check for any problems, and then I noticed that the Schmitt trigger was strange. A simulation confirmed it was incorrect; it was drawn backwards.
