Little Bee is an affordable, high-performance current probe and magnetic field probe that allows you to debug and analyze electronic devices more efficiently.
Core64 combines real core memory and LEDs in a unique interactive way. Core Memory is a magnetic memory technology from the 1960s and 1970s. The tip of the stylus has a magnet that interacts with the LED through Core Memory. In practice, users can think of it as a magnetic touch screen
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.
With features like adaptive cruise control, driver monitoring, automatic lane centering, etc., it is available for Toyota, Hyundai, Honda and many other brands, about 275+ models. openpilot complies with ISO26262 guidelines.
Open source closed-loop stepper motor controller (schematic diagram + source code), using PID algorithm control, AS5047 magnetic angle detection sensor, efficient anti-loss of steps, quick learning of PID algorithm, and mastery of microcontroller system development.
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.
The author specially bought a laptop motherboard, and then DIYed the peripherals and casing. The overall effect is quite beautiful.
A versatile LiDAR SLAM package. Supports various types of LiDAR sensors (mechanical, solid-state, etc.), 6-axis and 9-axis IMU, loose coupling and tight coupling, mapping and positioning, loop detection, etc.
The project presented here is a bipolar stepper motor driver. It is based on the BD63731EFV chip, a low-power driver driven by a PWM signal. The project power supply voltage is 8~28V DC, and the rated output current is 3A. The input interface adopts CLK-IN drive mode, and the excitation mode corresponds to FULL STEP mode (2 types), HALF STEP mode (2 types), QUARTER STEP mode (2 types), 1/8 STEP mode, 1/16 STEP mode through the built-in DAC . In terms of current attenuation, the SLOW DECAY/FAST DECAY ratio can be set without any restrictions and all available modes can be controlled in the most suitable way. Additionally, the power supply can be driven by a single system, simplifying design.
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.

Can measure DC/AC voltage, DC/AC current, resistance, inductance, capacitance, diode, frequency. Built-in 16bit ADC, digital filter, RMS effective value circuit and peak hold circuit. Multimeter control unit integrated with microcontroller, officially launched reference design kit, powered by button battery, including schematic diagram.
STEP400 is a stepper motor driver board that can control up to 4 axes. STEP400 elegantly combines all necessary functions, from communication to motor control, into a simple and complete package. STEP400 uses Open Sound Control (OSC) based on standard Ethernet rather than specialized industrial protocols to achieve ease of use while ensuring it is reliable enough for use in art, design or any other creative application. STEP400 can be easily controlled through creative coding environments such as openFrameworks, Processing, Max, Unity or Touch Designer. STEP400 is Arduino compatible, so you can drive the motors with your own code too.
