CaribouLite is an affordable open source dual-channel software-defined radio (SDR) platform and an SDR-focused FPGA development framework implemented as a Raspberry Pi (RPi) HAT. CaribouLite turns your Raspberry Pi single-board computer (SBC) into a standalone dual-channel radio Tx/Rx with a tunable spectrum up to 6 GHz. CaribouLite gives you complete control over its hardware, including FPGA, firmware, and all supporting software. With the deeply integrated IceStorm toolchain, writing your own FPGA applications couldn't be easier. You can reuse many Verilog modules, such as the SPI and SMI modules, to support custom applications for CaribouLite hardware.
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.
Mico is a high-quality PDM to USB audio microphone based on the Raspberry Pi RP2040 chip. Most compact microphones available for embedded Linux systems such as the Raspberry Pi have high noise and low sensitivity. By pairing a high-quality PDM microphone with a standard USB audio output, Mico gives you an audio input platform that you can tailor to your needs. Mico is a great platform to learn and experiment with the RP2040 and digital audio. It can be used as a universal USB microphone for a Raspberry Pi, desktop or laptop computer. Mico can also be used as a high-quality USB audio input for embedded machine learning applications. Additionally, because TinyML supports RP2040, Mico can be used as a standalone edge computing audio device.

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!
ShaRPiKeebo is probably the smallest Linux computer you can find with a physical QWERTY keyboard. Measuring just 6 x 11 x 1.5 cm, it's powered by a Raspberry Pi (RPi) Zero W or 2W and features a 400x240 pixel, low-power, daylight-readable, black-and-white SHARP memory display and long-range wireless transceiver.
ANT BBPS displays voltage, current and power on an OLED display. It features digitally controlled current limit, wide input voltage range and up to 12 V DC output. It also has two input connections, a USB type-C connector and a screw terminal. A USB input means a battery pack can easily be used as your power source, and the screw terminals allow any other input source to be connected, such as AA and 9 V batteries, or even that old 7 V wall adapter you might have lying around.
The author specially bought a laptop motherboard, and then DIYed the peripherals and casing. The overall effect is quite beautiful.
The standby time is acceptable and in good condition, more than 7 days.
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.
Have you ever thought about attaching an inertial measurement unit (IMU) to an object to track its posture and motion? Tracer provides high-performance, safe, reliable and low-cost object tracking. Tracer can be easily attached to objects using Velcro. It can tilt and track rhythm as the bike's frame tilts, it can record the number of shots taken with a tennis racquet, and it can even differentiate between topspin and chip shots. Let your imagination run wild and explore more interesting applications of Tracer!
The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.
