Hugging Face’s Reachy Mini is an open-source AI robot for your computer or Raspberry Pi 5

Reachy Mini

Better known for its artificial intelligence software solutions, Hugging Face has now introduced the Reachy Mini open-source desktop robot, designed to deploy AI applications that interface with the physical world. The robot comes with a camera, microphones, and a speaker, and can move its 6 DoF (degrees of freedom) head, rotate its body, or wave its antennas. Two versions are available: The Reachy Mini Lite designed for computers running Mac, Linux, and soon Windows, and the Reachy Mini autonomous robot, powered by a Raspberry Pi 5, adding wireless connectivity, a few more microphones, an accelerometer, and battery support. Both models share most of the same specifications: The Reachy Mini is programmable in Python for now, but JavaScript and Scratch will soon be supported too.  We’re also told that over 15 robot behaviors will be provided at launch on the Hugging Face hub, so users will be able to get started […]

Olimex RP2350pc computer board features Raspberry Pi RP2350B MCU, HDMI/DVI video output, 4x USB ports

Olimex RP2350pc

Olimex has launched an update to its RP2040pc computer board with the RP2350pc board powered by a Raspberry Pi RP2350B MCU coupled with 16MB flash, 8MB PSRAM, and offering HDMI/DVI video output, four USB 2.0 ports, and an audio Codec for retro computer emulation and education. Other changes include a microSD card slot for additional storage and an on-board stereo audio codec and amplifier for Line-in and headphone audio jacks, and left and right speakers. That also means the two buzzers from the RP2040 board are gone. The design is now closer to a proper retro computer board.

Anyshake Explorer specifications and key features: MCU – STMicro STM32F103CBTx Arm Cortex-M3 microcontroller  Sensors Geophone 3-axis 4.5 Hz velocity geophone (100 V/m/s sensitivity) Three geophone inputs Capture through a high-resolution 32-bit ADC IMU – 16-bit 3-axis accelerometer (±2 g full scale) Data acquisition Modes – Accelerometer-only mode, geophone-only mode, and simultaneous sampling (6 channels) Sampling rates – 50/100/200/250 SPS Networking – SeedLink protocol support, TCP raw data forwarding Host interface 2x RS-232 […]

Improved HackRF Pro open-source SDR platform supports 100 kHz to 6 GHz operating frequency

HackRF Pro

HackRF Pro is an update to the HackRF (One) open-source SDR platform first launched by Michael Ossmann from the Great Scott Gadgets through a Kickstarter campaign in 2013 that attracted close to 2,000 backers at the time, and is still popular since then. Compared to the HackRF One, the HackRF Pro has a wider 100 kHz to 6 GHz operating frequency, features more RAM and flash memory, supports 16-bit samples for low sample rates, eliminates the DC spike, improves RF performance with a flatter frequency response, has been designed with better power management, and implements other small changes such as switching to a modem USB-C port. HackRF Pro specifications (preliminary): MCU – NXP LCP43xx dual-core Arm Cortex M4/M0 microcontroller Logic – Power-efficient FPGA (instead of Xilinx CPLD) Frequency Range – 100 kHz to 6 GHz operating frequency Tunable from 0 Hz to 7.1 GHz Transceiver – Half-duplex Sampling rates – […]

ESPHome 2025.6.0 adds ESP32-P4 and OpenThread support

ESPHome 2025.6.0 ESP32-P4 OpenThread

The ESPHome 2025.6.0 open-source firmware was released on June 18, 2025, with ESP32-P4 support and an initial OpenThread implementation for ESP32-C6 and ESP32-H2 SoCs, thanks to an upgrade to the ESP-IDF framework to version 5.3.2. The developers note that support for ESP32-C6, ESP32-H2, and ESP32-P4 is still being refined, and some components may not yet be fully compatible with these chips, but additional component updates are planned for ESPHome 2025.7.0 next month. That still means that ESPHome devices can connect to Thread networks and communicate with Home Assistant through the Native API as long as you have an OpenThread border router and Thread is enabled in Home Assistant. Users should note some limitations to Thread support: ESPHome does not yet support the Thread “Sleepy End Device” mode Not recommended for applications requiring high-frequency sensor data transmission Best suited for simple control and monitoring use cases Other changes to ESPHome 2025.6.0 […]
