LTO Tape data storage for Linux nerds
Tape storage is surprisingly not dead! If you are here then you may be considering using LTO tape as part of your backup or your long term archiving strategy. I’m here to mostly talk you out of it, or at best make sure that you are aware of what you are walking into.

Patching an embedded synthesiser OS from 1996 with Ghidra
For reasons I won't get into, I've been working on a tricky reverse engineering puzzle recently: how to patch the operating system of a 26-year-old synthesizer. To be specific, the Kurzweil K2500, a...

You can't buy a Raspberry Pi right now
...or at least, not without a lot of patience or a fat wallet. But why? And are there any signs Raspberry Pis will become available to the general public again soon? To be clear, I'm speaking of the mainstream SBC Raspberry Pis, like the Pi 4 model B, the Compute Module 4, the Pi Zero 2 W, and even in many cases the…

Clip control on the Apple GPU
After a year in development, the open source “Asahi” driver for the Apple GPU is running real games. There’s more to do, but Neverball is already playable (and a lot of fun!).

M1 Thunderbolt ports don’t fully support USB 3.1 Gen 2
It’s limited to 5 Gb/s, giving read rates of about 400 MB/s and writes at about 430 MB/s. Fine for Time Machine backups, but bad with NVMe drives.

Oxide on My Wrist: Hubris on PineTime was the best worst idea
In my last Oxide-related post I got Oxide’s Propolis software running and said I might try and get their sled agent up and running next. Anyways that didn’t happen. Instead I ended up reading datasheets, writing rust codegen, spending 16 gigs of ram for an hour to build docs for a crate that’s just a glorified bundle…

A home made PCB stepper motor
The first idea is interesting because it means cheap, precision-manufactured PCBs can be easily transformed into cheap, precise tiny motors.

No, you can’t save £30 per year by switching off your “standby” devices

Energy Saving Trust@EnergySvgTrustA quick way to #saveenergy at home is to turn off tablets, laptops and consoles as soon as you stop using them…

Great AA Alkaline Battery Test (2016)

Life at 800 MHz
We’ve been using a Sony Vaio VGN-P588E for the past few months as our primary personal laptop. This thing’s great; it’s got a small but not uncomfortable keyboard. It’s got a trackpoint, which we absolutely need to keep our hands healthy. Crucially, it’s only 1.5 pounds. We’re disabled in a way that means we’ve got to…

Making a Stainless Steel Rubik's Cube
I wasn't entirely satisfied with the aluminum cube , so after thinking about the design for a while, I decided to make another one out of stainless steel. Just for fun, I thought I would make all the pieces using only manual machines. How hard could it be?

A Christmas tree bauble that plays Doom
Christmas is coming again, and generally that means christmas trees and everything in it: lights, streamers, and ofcourse baubles. The holiday is all very jolly and everything, so I decided it was lacking some doom... errm, I mean Doom. So I 3d-printed a small Christmas bauble modeled on an IBM PC, stuffed it with the…

Why are McDonald’s Self Service Kiosks so hackable?
McDonalds in Australia do a decent cup of coffee. It’s not great but it’s consistently decent so I often start my day with a cup. Due to my travels around Australia in a decked out van I have seen how many McDonalds operate and just how many of
