A new open-source project called JBR-001 offers a fully 3D-printable desktop companion robot powered by an Arduino Uno Q. The design and build instructions are published on Arduino's Project Hub, letting hobbyists print, assemble and program the robot themselves. Early reaction on Hacker News is positive, with commenters discussing the accessibility of a printable robot kit and what the Arduino-based platform makes possible for makers.

Arduino held a live session discussing its Uno Q and Ventuno Q boards, drawing questions and conversation from makers about the hardware. Attendees chatted about how the boards compare with Raspberry Pi single-board computers, with topics spanning Linux support, AI capabilities, AppLab, and robotics projects. The exchange reflects ongoing interest in Arduino's expanding line of boards for DIY electronics.

An open-source enthusiast has given a 13-year-old router a second life, upgrading its RAM and storage chip, adding I2C and GPIO ports, and building a screen and buttons into the lid. The device runs a custom-compiled OpenWrt system with cross-compiled Raspberry Pi and Arduino code, and reportedly works. The project is drawing attention as an example of how open-source software can extend the life of old hardware well beyond its intended lifespan.
