The SOCORAD32, also known as the ESP32 Software Controlled Radio, is a professional grade hackable radio for amateur radio exploration, voice and data communications using simple AT commands. Just add a speaker and batteries and you've got a fully functional walkie-talkie. With a dedicated Push-to-Talk (PTT) button onboard, SOCORAD32 works right out of the box without touching a line of code!
Plant Bot is an open source project based on ESP32 that allows a single PCB to perform the functions of detecting humidity, watering, providing lighting, and controlling and communicating with the user via WiFi/BLE.
This BLDC motor driver board is capable of driving one BLDC motor, or one or two bidirectional DC motors (H-bridge configuration, cascaded to support a second motor) or up to three unidirectional DC motors (half-bridge configuration).
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.
This is what smart home enthusiasts want to control their entire lights, thermostat, or any other smart device from their couch without having to activate a wall switch.
The 5kW evaluation board represents Infineon’s inverter-level solution for high-power motor control applications such as forklifts or low-speed vehicles. This reference design demonstrates the performance of Infineon's power MOSFET family OptiMOS™ in the new TO-Leadless package in terms of parallelization and thermal behavior.
Turnkey reference design kit for low voltage, high performance, high efficiency and high speed PMSM/BLDC motor drive applications is a reference design kit using the IMC101T iMOTION controller, 2ED2304 SOI half-bridge gate driver and BSC030N04NS OptiMOS. This reference design kit showcases our thin-film SOI and advanced motion control engine (MCE 2.0) technology enabling drive speeds up to 120KRPM for low-voltage permanent magnet motors, while the inverter section is rated up to 30 V and 25 A. It has been optimized for low voltage appliances such as vacuum cleaners, fans, pumps, compressors and other low voltage motor drive applications.
SmartKnob is an open source input device with software-configurable stops and virtual locators. The brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, allowing the feel of the detent and stop to be dynamically created and adjusted.
Flipper Zero is a portable multi-tool designed for developers and geeks with a toy-like body. It enjoys exploring digital content such as radio protocols, access control systems, hardware, and more. It's completely open source and customizable, so you can extend it in any way you like.
EVB-LIV3FL is a complete standalone evaluation platform for Teseo-LIV3FL low power GNSS module ST solution.
“Using the color of the desk lamp to show the growth rate of COVID-19 virus infections in a country or region, the display effect is more intuitive and not as stressful as chart data.”
Alex Newton released an IoT electrocardiogram monitoring (ECG) tutorial based on ESP32, demonstrating that remote cardiac monitoring can be carried out no matter how far the distance is between the doctor and the patient.
Alan Wang, a maker from Taiwan, used the MAX7219 LED module, the ESP8266-based D1 micro development board and MicroPython to develop a small tool that can update COVID-19 data in various countries in real time.
A distance monitor based on ESP8266 can remind people to maintain appropriate social distance at any time during the COVID-19 epidemic to prevent the spread of the virus.
Let’s see how to easily hack a remote control using ESP8266.
A low-cost, non-contact DIY infrared thermometer based on ESP8266 can help people measure their temperature safely and prevent the spread of the new coronavirus.
