RP4B based dual-arm robot offers 13 Degrees of Freedom
The myBuddy by Elephant Robotics, is a dual-arm platform built around a Raspberry Pi 4B. This platform is enabled with thirteen Degrees of Freedom (DoF) and a maximum payload of 250g for each arm. The platform also supports VR control and integrates a 7” touchscreen display.
Following the introduction of the mechArmPi 270, the myBuddy is another robotic platform based on Raspberry Pi 4B developed for students or software developers. The myBuddy already provides preconfigured movements/functions, however it can also be programmed by beginners (i.e. Blocky) or advanced users (i.e. Python, ROS and RVIZ).

Automated MicroSD Card Swapping Helps In Embedded Shenanigans
[Saulius Lukse] has been working on some single board computer, seemingly, running Linux. Naturally, that boots from a microSD card – and as development goes on, that card has to be reimaged all the time. Sick of constantly plugging and unplugging the microSD card between the SBC and an SD card reader, [Saulius] started looking for a more automated solution – and it wasn’t long before he found out about the SDWire project, a hardware tool that lets you swap a card between a DUT (Device Under Test) and your personal computer with no moving parts involved.

How to get NixOS hosted at OpenBSD Amsterdam
In this guide, I'll explain how to create a NixOS VM in the hosting company OpenBSD Amsterdam which only provides OpenBSD VMs hosted on OpenBSD.
I'd like to thank the team at OpenBSD Amsterdam who offered me a VM for this experiment. While they don't support NixOS officially, they are open to have customers running non-OpenBSD systems on their VMs.
