I regret building this $3000 Pi AI cluster
I ordered a set of 10 Compute Blades in April 2023 (two years ago), and they just arrived a few weeks ago. In that time Raspberry Pi upgraded the CM4 to a CM5, so I ordered a set of 10 16GB CM5 Lite modules for my blade cluster. That should give me 160 GB of total RAM to play with. This was the biggest Pi cluster I've…

CubeSats are fascinating learning tools for space
These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space…

How big a solar battery do I need to store all my home's electricity?
I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a…

Weird CPU architectures, the MOV only CPU (2020)
I like CPU architectures, especially weird, interesting and unusual ones. For example, the Intel iAPX 432 is still something I would love to play around with. Recently, I realized that a working CPU can be made with just a simple Move instruction. For this to work, everything needs to be memory mapped. The ALU…

Racintosh Plus – Rackmount Mac Plus
I own a Macintosh Plus from 1986, I found it in the mid 2000's on my college campus on a free-to-a-good-home shelf (Mad Marc's shelf in the chemistry building) in great shape and with its mouse, keyboard, and an HD-20 external hard disk drive. That silly computer has been on the journey with me ever since, leaving…

I am giving up on Intel and have bought an AMD Ryzen 9950X3D
