NetSoM: Lowering the Barrier to Entry for Ethernet, Wi-Fi, 2G, 3G, Audio, Video and IoT Applications

NetSoM is a family of open source, OpenWrt-powered system-on-module (SoM) kernels and the development boards that host them. Combined with our sample code base, these boards allow developers to go from scratch to mass production in record time. With support for Wi-Fi connectivity and two Ethernet phy ICs, it is soldered to a development board with two RJ-45 Ethernet ports. NetSoM is currently in production as an industrial LoRaWAN gateway solution, but it is widely applicable in areas as diverse as home automation, automotive networking, audiovisual data processing, and smart cities. As part of this project, we are releasing software for a variety of useful NetSoM applications. Among them are: an audio streaming (SIP telephony) application using the WM8960 codec, a video streaming (RTSP/MPEGTS) application using the OV5640 camera module, an Alexa-style speech recognition application, a UDP to CAN forwarding application, a LoRaWAN Gateway Application

Data Fitness Connector (DFC): Allows Peloton bikes to communicate with fitness watches and other connectors (schematic, source code, PCB, etc.)

Data Fitness Connector (DFC) A data broadcaster is a device that allows Peloton bikes to communicate with fitness watches, head units, and apps, a feature not available on stock Peloton bikes. It reads power and cadence data in real time via a cable connected to the bike and broadcasts them wirelessly to nearby devices, including those built around non-Peloton platforms like Zwift and Garmin (see which products are supported). This allows you to enjoy the built-in features of your bike while taking advantage of features and services that rely on third-party platforms.

HEGduino V2: Cerebral blood map monitoring

Since the release of HEGduino V1, we have been working continuously for more than a year and a half to develop a compact, state-of-the-art open hardware solution for home NIR-HEG biofeedback. HEGduino V2 is an original design that brings you low-cost, intuitive home brain training and research-grade cerebral blood flow monitoring. This new device also allows us to incorporate heart rate variability (HRV) training and even monitor breathing and skin temperature. HEGduino V2 is comfortable. Easy-to-use headset with wireless operation and battery power. These components are breakout boards that allow you to remove them from the headset for easy patching or replacement.

SlimeVR Full-Body Tracker: An affordable, comfortable, wireless, 360° virtual reality full-body tracking solution

SlimeVR is a set of open hardware sensors and open source software that facilitates full-body tracking (FBT) in virtual reality. Without the need for a base station, SlimeVR makes wireless VR FBT affordable and comfortable. SlimeVR FBT provides simple, effective body and limb tracking in VR games and other applications. It utilizes high-quality inertial measurement unit (IMU) sensors and a Wi-Fi connection to a PC instead of wires, cameras or base stations to make full-body tracking comfortable and affordable. Take the lower-body suit, for example, where five trackers—one on each thigh, one on each ankle, and one on the waist—are enough to get the job done. Each tracker monitors its own rotation in space, and the SlimeVR software uses your scale and headset position to calculate joint angles and estimate limb position. In more technical terms, SlimeVR relies on absolute orientation sensors, a configurable skeleton model, and forward kinematics. The result is like having virtual Vive trackers installed at strategic locations on your body.

Chhavi: ESP32 based fingerprint sensor with optional NFC (source code, etc.)

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.

Newt: a low-power, open-source, 2.7-inch IoT display powered by the ESP32-S2 module and powered by Sharp’s Memory in Pixel (MiP) screen technology

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.
