3600 MHz Raspberry Pi 5 with Liquid Nitrogen
I tried everything but couldn’t turn this Raspberry Pi 5 into the World’s Fastest Pi 5. Unfortunately, we can’t quite claim that title.

External boot disks still don’t work properly with M1 Macs
Making an external bootable SSD for an M1 Mac has proved tricky. Has this changed in macOS 11.2? If you’ve already got 11.1 running on one, how do you update it to 11.2?

Windows 8 and the Microsoft Surface
Right now, people are burying Windows 8. Even people you'd normally expect to be on Microsoft's side are unhappy with it. Me, though? I kind of like it.

How Apple's developers reflashed Mac ROMs in the '90s
After I wrote about the possibility of programmable Mac ROM SIMMs in Quadras a couple of months ago, I suspected that there had been a way for developers at Apple in the 68k Mac era to reflash the ROM in their Macs during development, just like BIOS updates on PCs. The reason I believed this is because the ROM SIMM…

Golang on the Playstation 2
The PS2 is more than capable of doing some wild things, including running Linux. I always wondered if we could just write baremetal Go code on it, so I decided to give it a try.

Is AM radio dead?
...that was the question I asked my Dad, a radio engineer for many decades, who worked at the biggest AM station in St. Louis, KMOX. The station is approaching its centennial in 2025, as are—some YouTube commenters argue—its primary audience! I recorded that video during my convalescence at my parents' house (I am…

The Mythical Non-Roboticist
What if everyone could do robotics? That would be great, right? We should make a software framework so that non-roboticists can program robots.This idea is so close to a correct idea that it's hard to tell why it's a mistake.

Restoring and MIDI-Fying a Baby Grand Piano
As much as I love digital instruments, synthesizers and other electronic gear I also really love the look and feel of instruments made from wood, brass, steel and felt. There is objectively no difference between the best digitally sampled pianos but for some reason it doesn’t quite feel as much alive as an actual…

3Hz Computer, Hold the Transistors
I’m not really one to brag publicly about expensive toys, but a few weeks ago I managed to get one that’s really something special. It is a Curta Type II , a mechanical digital 1 calculator manufactured in Liechtenstein between the 50s and 70s, before solid-state calculators killed them and the likes of slide-rules.
