Docker for Microcontrollers? AkiraOS combines Zephyr RTOS with WebAssembly (WASM) applications

AkiraOS is a Zephyr-based embedded OS that runs sandboxed WebAssembly applications on microcontrollers and lets users deploy and update firmware OTA without reflashing. In other words, it’s similar to Docker containers, but for microcontrollers. The open-source embedded platform separates the OS from the application. That means the firmware stays stable, while apps are independent .wasm binaries deployable over-the-air without touching the OS, and portable so a single binary works on ESP32-S3, nRF5x, or STM32 MCU boards. AkiraOS highlights: User space Up to 8 wasm apps can be installed Up to two apps can run at the same time Footprint: 50KB to 200KB per app Akiraz runtime – Custom WASM runtime App Manager UI Framework with 32 widgets Shell/console 18 API modules WebAssembly Micro Runtime (WAMR) – Two options: Interpreter or Ahead-Of-Time (AOT) compilation with 10 to 50x higher performance RTOS – Zephyr RTOS Scheduler Network stack HTTP for OTA updates […]

Sharpa Wave is a high-end dexterous robotic hand with 22 DoF, high-sensitivity dynamic tactile array

NVIDIA just announced the Isaac GR00T Reference Humanoid Robot in a half-baked press release for Computex 2026, with an “available-soon reference workflow” and availability sometime by the end of the year with the Unitree H2 humanoid chassis. One component of the kit that appears to be available now, albeit in limited quantity, is the Sharpa Wave high-end dexterous robotic hand with 22 degrees of freedom (DoF) and a dynamic tactile array (DTA) on each finger, enabling it to feel objects as lightweight as a butterfly. Sharpa Wave robotic hand highlights: 1:1 scale human form – The palm width to hand length ratio is approximately 0.618, enabling the Wave to manipulate the same tools as humans. 22 active Degrees of Freedom – Isomorphic design mirroring the human hand Dynamic Tactile Array (DTA) powered by a proprietary neural network-based algorithm and sensing modules to enable detection of tight objects (like a butterfly) […]

LichtBit’s open-source ESP32 Art-Net/sACN NeoPixels controller can drive up to 2,720 RGB LEDs

Dutch hardware designer LichtBit has launched a fully open-source ESP32-based Art-Net/sACN NeoPixels LED strip controller designed for large-scale lighting installations and custom stage design. Built around an ESP32, the hardware routes lighting data over wired Ethernet or Wi-Fi to manage up to 16 universes of addressable LEDs across 4 dedicated outputs. We have previously written about various NeoPixel LED controllers, such as the xcrhom WLED Type-C, the Adafruit Sparkle Motion Stick, the full-featured Adafruit Sparkle Motion, and others, which are designed for portable lighting setups and standalone animations. But LichtBit’s board targets the professional event industry by bridging the gap between commercial live-performance software (such as Resolume Arena, MadMapper, or xLights) and low-cost digital LED strips. LichtBit’s Art-Net and sACN LED controller specifications: Development Board – Generic ESP32 based developmt board with ESP32-WROOM-32 MCU Display – 128×32 I2C OLED display for real-time device configurations, status, and IP mapping Network 10/100Mbps Ethernet via WIZnet W5500 […]

RAKwireless WisMesh Pi HAT RAK6421 turns your Raspberry Pi 4/5 into a modular Meshtastic gateway

RAKwireless WisMesh Pi HAT RAK6421 is a modular Meshtastic gateway expansion board for Raspberry Pi 4/5 that adds support for the company’s WisBlock ecosystem. Designed for users running meshtasticd (the Linux-native Meshtastic service), it enables scalable, always-on Meshtastic base stations, MQTT gateways, and backbone relay nodes. Unlike other LoRa solutions based on Raspberry Pi, the RAK6421 takes a modular approach. Instead of a built-in radio, it offers two WisBlock IO slots and four sensor slots, allowing users to easily plug in or swap modules. This means you can choose between standard LoRa modules like the RAK13300 or higher-power 1W versions like the RAK13302, without dealing with messy USB adapters or breadboard wiring. RAK6421 WisMesh Pi HAT RAK6421 specifications: Compatibility Raspberry Pi 4, Raspberry Pi 5, and Raspberry Pi Zero 2W SBCs Potentially other SBC with standard 40-pin Raspberry Pi GPIO header (HAT+ compliant) Expansion 2x WisBlock IO slots for LoRa radio […]
