• DietPi v8.14 Release Is Now Available

  The February 11th, 2023 release of DietPi v8.14 comes with a new image for the Radxa ROCK 5B, Odroid N2/HC4, Orange Pi 5 and a couple of improvements and bug fixes.

• DiscoBSD - 2.11BSD-based UNIX-like Operating System for STM32 and PIC32 Microcontrollers

  DiscoBSD is a 2.11BSD-based UNIX-like operating system for microcontrollers, with a focus on high portability to memory constrained devices without a memory management unit. This microcontroller-focused operating system is the continuation of RetroBSD, a 2.11BSD-based OS targeting only the MIPS-based PIC32MX7. DiscoBSD is multi-platform, as it also supports Arm Cortex-M4 STM32F4 devices. Source code to the system is freely available under a BSD-like license.

• This 3D-printed robot is made for sumo battle tournaments

  While the majority of makers are unable to afford the fancy equipment and components that go into modern state-of-the-art battle robots, there do exist lesser-known tournaments for more DIY designs, including sumo robot battles.

• Using sensor fusion and tinyML to detect fires

  The damage and destruction caused by structure fires to both people and the property itself is immense, which is why accurate and reliable fire detection systems are a must-have.
