HealthyPi 6 – A portable Wi-Fi 6 biosignal acquisition device with ECG, PPG, respiration, and temperature sensors (Crowdfunding)
Designed by ProtoCentral Electronics in India, the HealthyPi 6 is an open-source, portable, research-grade biosignal acquisition device designed for academic research, education, and prototyping. It targets labs, classrooms, and field studies that need professional-quality physiological measurements without bulky desktop systems or proprietary lock-in. Building on the HealthyPi 5 (2023) and HealthyPi 4 (2019), the HealthyPi 6 is a standalone device with 3-channel/5-lead ECG, dual-wavelength PPG for heart rate and SpO₂, respiration via impedance pneumography, skin temperature sensing, and a 9-axis IMU for motion and artifact detection. Built around the STM32H757 real-time microcontroller and an ESP32-C6 handling Wi-Fi 6 and BLE...
VEGA AS2161 “DHRUV64” – A 1GHz dual-core 64-bit RISC-V microprocessor designed in India
The Government of India has been investing to spur up its semiconductor design and manufacturing industry at least since 2018/2019 with the SHAKTI and AJIT microprocessors. In 2022, they decided to focus on the RISC-V architecture with the VEGA processor family, starting with the THEJAS32 (VEGA ET1031) and THEJAS64 (VEGA AS1061) microprocessors, and the former was eventually found in the ARIES v3.0 Arduino UNO-inspired development board. Things continue to progress nicely, albeit slowly, and the government has now announced the launch of the DHRUV64 (VEGA AS2161) dual-core 64-bit RISC-V MPU clocked at 1 GHz and supporting Linux, which it describes...

The ESP Private Agents platform aims to ease the development of ESP32-based AI voice assistants with on-device processing
Espressif has just introduced the ESP Private Agents platform to help developers build local, private, and customizable AI assistants for ESP32 devices running on-device, although they can also support hybrid AI workloads with a mix of on-device and cloud processing. The ESP Private Agents platform offers a unified framework that allows developers to build applications combining speed, vision, automation, and agent-based interactions, for example, a multi-lingual, on-device voice agent (aka smart speaker) or task-oriented agents that automate workflows. The solution is built on AWS cloud services using AWS Fargate as a primary application platform and Amazon Bedrock Foundation Models as...
tinySA is a low-cost handheld spectrum analyzer with built-in signal generator
The tinySA is a compact, low-cost handheld spectrum analyzer and RF signal generator designed for hobbyists, radio amateurs, educators, and engineers. It comes in three different variants and can be used for RF debugging, signal inspection, interference hunting, filter testing, antenna-related measurements, and basic RF education, both in the field and on the bench. The product line includes the tinySA Basic, tinySA Ultra, and tinySA Ultra+, which mainly differ in their supported frequency ranges and performance. The tinySA Basic supports 100 kHz to 350 MHz on its low input and up to about 960 MHz on the high input, while the...

reTerminal E1001/E1002 Review – B&W and color ePaper displays tested with SenseCraft HMI and Home Assistant
Seeed Studio sent us samples of the reTerminal E1001 (monochrome) and E1002 (color) ePaper displays for review. They are powered by an ESP32-S3 microcontroller providing WiFi and Bluetooth LE wireless connectivity, and are designed for low-power information display applications, consuming power only when updating the screen content. This makes them ideal for tasks requiring long battery life (average of 3 months per charge, depending on how often they are updated) and always-on display capabilities. In this review, we will unbox the devices, go through a teardown, and test them with Seeed Studio’s SenseCraft no-code HMI platform, as well as ESPHome...
