The host computer can use the official Saleae Logic, address: https://saleae.com/downloads/. Since the channel number on the software does not have ch0, ch1 corresponds to ch0 on the analyzer, and so on.
Designed by Altium designer21 software, the upper and lower shells are connected together and need to be cut by yourself. Most of the resistors and capacitors are packaged in 0402. The main chip CY7C68013 is packaged in QFN, which greatly reduces the size.
I use at24c02 burned with stm32. The source code is provided in the attachment (modified using the wildfire routine). It would be more convenient if there is a ch341A.

ESP8266 heating stage
Introduction: EPS8266 400W upgraded heating table
According to the transformation of Qifan Science and Technology, the PCB layout and wiring are optimized, especially the high-current lines are thickened, and the windows are opened and tinned to ensure high-power load. It has been used many times and works very well, but the temperature is not calibrated because there is no thermometer. It can be used normally at about 170 degrees.

MAX-II development board, BGA welding practice board
Introduction: MAX-II development board: EPM570F256C5N
There is a 4-digit digital tube onboard (but it has not been tested yet, and I don’t know if the IO port driving capability is sufficient), two LEDs, and two buttons.
Because of the BGA outlet of the four-layer board, not all the IO ports are pulled out, only a few are not pulled out.
You can order for free from Jialichuang and buy two pieces at home, but they are not soldered well. Let's wait until the school re-solders them.

ZVS induction heating 1kw
Introduction: 1kw ZVS induction heating, basically all circuits (large areas of copper cladding) have windows to ensure current carrying capacity
Based on a foreigner's video, he used a 48V20A power supply for the demonstration, so 1000 watts should be no problem, about 12V~48V, and you can add heat dissipation.

Heated control panel (verified)
Introduction: Everyone has been working on a heating table recently to make it easier to solder boards. I also made a small control board with the things I had on hand. I did not use PID control. It may be added later.
Everyone has recently been working on a heating table to make it easier to solder boards. I also made a small control board using what I had on hand. I did not use PID control, but may add it later.
The F401CCU6 used and the core board used are from WEACT. There are many pirated versions on the Internet. The genuine version seems to have been removed from the shelves. The address of the pirated version of
the heating plate is based on this project: Hilbert Curve of the Big Guy.

FM5324GA charge and discharge module snowflake lamp base
Introduction: Battery charge and discharge module based on FM5324G, snowflake lamp base
FM5324GA charging and discharging module snowflake light base
overview
FM5324GA is an integrated power management IC used in mobile power supplies that integrates lithium battery charging management, battery boost output, battery power judgment and LED power indication.
FM5324GA is charged in a switching mode, including trickle charging, constant current charging and constant voltage charging. The float charging voltage accuracy can reach ±1% in the full temperature range, and has small charging current ripple and high charging efficiency. High advantages.
The DC-DC boost of FM5324GA can achieve an accuracy of ±1%, and can provide a boost conversion efficiency of more than 94%, extending battery life.
FM5324GA is equipped with 3 LED drive ports, which can drive 4 LEDs to display battery power. The chip has a built-in logic lock function to prevent the power indicator from being unstable.
FM5324G has multiple protection designs, including load overcurrent protection, soft start protection, input overvoltage protection, output short circuit protection, chip temperature protection, battery temperature protection, etc. At the same time, the chip port is designed with a high-performance ESD protection circuit, making the chip extremely reliable.
Introduction
1. There is nothing to introduce. Look at the pictures. The upper and lower boards are connected and powered through copper pillars.
The pictures show
that I have no money to buy batteries, so the batteries will be replenished in the near future.
