Rethinking the Commodore 64 Memory Map (2018)
I've had my head down, programming away on C64 OS, and been making some great progress. I've tweeted a few things out, some of which are revealing of things I've either never talked about here or even seem to contradict what I've said here. So I'd like to take a breather and talk about some of these developments.

The Qweremin
In the summer of 2022 I built a C64-based theremin, described and explained here . The theremin, of course, is one of the oldest electronic instruments. Its main drawback—and strength—is that it's incredibly hard to master. The performer has ultimate control over volume and pitch, but it takes months of practice…

FreeBSD on the Graviton 3
As far as FreeBSD is concerned, Graviton 3 is mostly just a faster version of the Graviton 2: Most things "just work", and the things which don't work on Graviton 2 — hotplug devices and cleanly shutting down an instance via the EC2 API — also don't work on Graviton 3. (Want to help get these fixed? Sponsor my work on…

The Laser Doodler
So I’ve got a project coming up (that may have something to do with this tweet ) that will require a few LED matrix displays. I found a suitable candidate online and ordered one to play around with. Since I already had the display, I thought it’d be fun to run it through the paces and build a little circuit out of it…

Sanyo Triple Five
Even though I seem to have terrible luck with x86-based computers, that doesn’t mean I have to take it lying down. I can go out there and cause even worse things to happen to me. Like, for instance, buying a broken super-budget PC-incompatible from 1982.

Is the Intel N100 a better option than high-end ARM RK3588 boards at the moment?
The Intel N100 (and N200) seem to be Intel's attempt at trying to muscle into the market that high-end ARM SoCs look to have cornered. With the Rockchip

Trying every combination to flash my Asus motherboard's BIOS
tl;dr: Use an old-fashioned USB 2.0 flash drive, format it FAT32, download the firmware, make sure it's named correctly, and use the motherboard's 'BIOS Flashback' option after powering off the computer. This past week, I devoted far too much time to the task of updating my brand new motherboard's BIOS. It started…

Project Mini Rack – compact and portable homelabs
Today I'm announcing Project MINI RACK, an open source project to help those building homelabs, RF/wireless rigs, and other electronics projects into mini 10" racks. Not everyone can afford (either due to budget or space constraints) to have a full 19" rack in their home. Besides that, people may want to deploy small…

Exceptional failure: breaking the STM32F1 read-out protection
The firmware of microcontrollers usually contains valuable data such as intellectual property and, in some cases, even cryptographic material. In order to protect the confidentiality of these assets,
