Raspberry Pi security alarm – the basics
In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens. Integration with Home Assistant would be an add-on, not a requirement.

6 Raspberry Pis, 6 SSDs on a Mini ITX Motherboard
A few months ago someone told me about a new Raspberry Pi Compute Module 4 cluster board, the DeskPi Super6c. You may have heard of another Pi CM4 cluster board, the Turing Pi 2, but that board is not yet shipping.

How is the free firmware for the Raspberry progressing?
Raspberry Pi computers require a piece of non-free software to boot — the infamous raspi-firmware package. But for almost as long as there has been a Raspberry Pi to talk of (this year it turns 10 years old!), there have been efforts to get it to boot using only free software. How is it progressing?

We Need New Motherboards Before GPUs Collapse Under Their Own Gravity
You can’t have a 4-slot GPU. You just can’t. We have finally left sanity behind, with nvidia’s 4000 series cards yielding a “clown car” of absurd GPU designs, as GamersNexus put it. These cards are so huge they need “GPU Support Sticks”, which are an actual real thing now. The fact that we insist on relegating the GPU…
