SwarmDrive based on ESP32 has rich teaching documents, professionals and students can use it to easily learn various commutation algorithms and related knowledge of BLDC motors.
Picoclick is a simple IoT button in a very small package. The size of the PCB is only 18x20mm, and the height with the 300909 battery is only about 10mm. It's able to connect to your local WiFi at an impressive speed of about 1.5 seconds on average. Yes, since it calls IOT-Button, it uses WiFi of course! This opens up countless possibilities for that little device.
Use the Android cable to connect the voice chip and connect it to the computer. At this time, there is a removable disk on the computer, and then put the sound file into the removable disk... Materials used: Voice playback module Yabo 51 microcontroller (refer to this microcontroller The digital tube and the 8 free IO ports can be used) 3 10k resistors... Put the sound file into the voice chip and connect the data line and power line to the microcontroller. Use the keil tool to generate the hex file from the c program. And write it into the microcontroller...
The design is a custom 3d model from Sensirion. Sensirion provides a 3d model, but it has very few features.
The EPC901 is a 1024x1 CCD sensor capable of providing 50MHz pixel output. It outputs analog voltage from the CCD element. The author paired it with a 50MSps ADC on a SYZYGY board. The datasheet says it can run up to 50k fps. External I/O is provided via optocouplers to facilitate connection to external trigger sources such as motion controllers. This board will assist in conducting experiments on the new PnP platform. Objects can be moved through the line scanner to capture the position of the photo.
Picoclick-C3 The name relates to its new processor, the ESP32-C3, a single-core RISC-V 160MHz CPU. Picoclick C3T is a small WiFi and BLE IoT button suitable for a variety of applications. Originally designed for smart homes, Picoclick can also be used as an actuator for IFTTT automation or as an MQTT device. It is based on the single-core ESP32-C3 RISC-V processor, so it has a lot of useful features. The C3T measures just 10.5mm x 18mm.
It is a very beautiful and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
This project applies the bidirectional Z-source inverter to the motor drive system of pure electric vehicles. Using TMS320F2808 DSP as the control core, the SVPWM control technology based on the Z-source inverter is implemented.
A Russian Github master has open sourced a DIY lidar project, from PCB to host computer software.

Gregory Davill is a technical expert from Australia who is very famous and active in the field of open source hardware. In December 2020, he insisted on designing a circuit board every day, using KiCad to complete the circuit design and PCB layout and routing. This is the adventure-calendar-of-circuits-2020 project. This design is a JTAG programmer based on FT232H.

The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
