The color screen projection assistant uses the tcp protocol to send the computer screen to esp32 for processing and display in real time, with a theoretical frame rate of more than 10 frames
Hamster Mix is a portable MIDI controller powered by Arduino that connects to MIDI via Bluetooth. It allows you to control effects and play MIDI notes in 5 octaves. Twelve keys and the ability to switch up and down through the octave make it easy to control the notes of an entire keyboard piano using our compact controller (about the size of a hamster). Hamster Mix connects to Mac, PC, Ipad and even mobile phones via Bluetooth. You can control any MIDI-enabled music program such as Ableton, Garage Band, FL Studio, Reaper, etc. Two additional buttons and two potentiometers allow you to set up your own custom effects. You can even use the buttons as a Bluetooth track launcher instead of a keyboard. You can control MIDI-enabled mobile applications such as GarageBand, FL Studio Mobile, Reason Compact, Audiokit Synth One, Moog applications, and more. Make music on the go with Hamster Mix, which fits in your pocket, meaning no wires or bulky equipment.

PCA2117 Demonstration Board
The charger program written with STM8S003 has positive and negative pulses throughout the process, anti-reverse connection, scheduled shutdown during charging, and negative pulses to repair the battery later.

Infrared remote control Proteus simulation circuit transmitting and receiving program
I have an SD2405ALPI-G on hand, and I happen to have an STC learning board, so I made a clock with an annual error of about 2.5 minutes to play with. The schematic and program are all there. Now the hardware has a ringtone generating chip and a power amplifier chip, but the program has only initially implemented the function of displaying the day of the week, hours, minutes and seconds. It will be changed to an alarm clock when there is time.
Electronic keyboard design based on 51 microcontroller.
The power supply has a stable symmetrical +/- 40 V to ensure optimal performance.
Maximum power (THD 1%) approaches 100 W into 8 Ω load and 190 W into 4 Ω load (see measurements). All parts are through-hole, making it easy to build the amplifier. The design is completely symmetrical.
MSP430F149+1602 digital display and real-time clock
Freedom KL03Z hardware FRDM-KL03Z is easy to use and exquisitely designed. It uses the Kinetis L series MCU based on the ARM® Cortex®-M0+ core.
This 45W Type-C PPS reference design uses Infineon's EZ-PD™ PAG1s and PAG1P controllers and CoolGaN™ 600V GIT HEMT. The solution complies with international energy efficiency standards including DoE Level 6/CoC Level 2, and its standby power can be as low as less than 30 mW. The solution is tested to CE standards defined by CISPR32 Class B and achieves a high board-side power density of 17.71 W/in3. This solution is designed for use with USB PD (including PPS), QC power adapters. Adapters covering traditional charging protocols including Apple Charging, BC1.2, QC 3.0 and Samsung AFC are also supported. PAG1S and PAG1P jointly provide low BOM cost, high-performance solutions compatible with PD/PPS/QC.
