cuplTag is a battery-operated NFC tag that records ambient temperature and humidity. Tap it with your NFC-enabled phone and you'll see the timestamped reading appear in the web app. No configuration required, no application installation required, just one step!
Chhavi is a tiny, wireless, touch capacitive fingerprint sensor with high-end security features, support for ultra-low power operation and optional NFC connectivity. Its open source firmware is fully compatible with the Arduino IDE. Chhavi is powered by ESP32 and features an FPC BM-Lite fingerprint sensor by Fingerprints, giving you and your projects access to the excellent biometric hardware found in many smartphones. Unlike optical fingerprint sensors that are large and power-hungry, this capacitive biometric sensor is small, accurate, and energy-efficient. During our design process, we determined that NFC communication would be a powerful feature for many of the same applications that might require a high-quality fingerprint sensor, but we could not find a major ESP32-driven NFC controller. So we built one into Chhavi as an optional feature. We've also added an optional battery to simplify installation and facilitate mobile deployment. The result is a tiny device with a cutting-edge fingerprint reader, Wi-Fi and Bluetooth capabilities, as well as support for NFC and battery power when needed.
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.
Newt is a battery-operated, always-on, wall-mounted display that can retrieve weather, calendars, sports scores, to-do lists, quotes...anything on the internet! It is powered by the ESP32-S2 microcontroller and you can program it using Arduino, CircuitPython, MicroPython or ESP-IDF. We think Newt is the next step in the evolution of low-power display panels. Sharp's Memory in Pixel (MiP) technology is ideal for manufacturers, avoiding the slow refresh times associated with E-Ink displays. To support timers and alarms, we also added a real-time clock (RTC). Finally, we designed the Newt with battery operation in mind—every component on the board was chosen for its ability to run with low power consumption.
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.
Loko is an open source, battery-operated GPS tracker. It's a small, simple, and useful device that sends navigation data to its receiver via a peer-to-peer LoRa radio. Unlike other similar technologies, there are no ongoing costs. Loko is based on radio communication and requires no SIM card/monthly fee. It also works everywhere, even without 2G/3G/LTE coverage.
HiPo is a 3.52-inch e-paper display module the size of a business card. Content is uploaded via NFC via a convenient app, no batteries required. The development board can compile different display functions by editing the code.
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 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.
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.
