tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially…
Like some of you, we have several kitchen appliances with integrated digital timers.

Since recording a handful of C Programming on System 6 videos, I've occasionally wanted to live-stream the more casual daily programming being done on my Macintosh Plus. After getting all of the pieces together, I now have a working self-hosted broadcasting setup.
After viewing our CGA Redux livestream a friendly tinkerer named Arek contacted me if I was interested in a homebrew Hercules Graphics Card PCB that he designed. Naturally I said yes and assembled the card, playing beta tester for his design. It will probably be open sourced eventually, but is not yet available. So…
The microSD ware for January 2010 was not an incidental post. It is actually snapshot of a much longer forensic investigation to find the ground truth behind some irregular Kingston memory cards.
The Apollo missions to the Moon required complex hardware to communicate between Earth and the spacecraft, sending radio signals over hund...
Sitting and literally gathering dust on a shelf has been my childhood 2-XL toy . A few years ago I turned it on and it seemed to work but th...
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.
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…
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…

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…
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.
In a previous article, I revealed one of the secrets to MartyPC 's accuracy, hardware validation . To summarize, it is a method of using a m...
At the end of December, Apple made good on the release of the new iMac Pro and started selling and shipping the new workstations. While this could be characterized as a stop-gap effort until the ne…

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
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…
IFNews reports that TSMC will build a OEM production line exclusively for Sony to produce high-end CIS in 28nm process at the Nanke 14B fab...
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…
Towards the end of last year, I got a new laptop: the Purism Librem 13. It replaced the Lenovo ThinkPad X250 that I was using previously, which maxed out at 8 GB RAM and was beginning to be unusabl…

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,
A couple of weeks ago I found a really good deal on a Socket AM4 motherboard that supports the newest AMD Ryzen CPUs. The motherboard is an ASRock A520M/ac . It’s a very basic motherboard which doesn’t appear to be sold by any of the usual retailers anymore, but I couldn’t pass up on the deal, especially with the…
Many circuits, such as a computer power supply or a phone charger, require a stable voltage reference, but it's harder than you might expec...
