Creating the PiRS232 and playing with the Pi over serial has been leading towards an idea - I wanted to create a small, battery powered device, a sidecar that I could carry with my Psion and use as portable Linux terminal. I also managed to turn it into an Internet...
If you know how to use a command line, you can build one
Acquiring and tricking out a 1989 Apple Macintosh SE/30, the greatest Mac of all time
Imagine a smartwatch you could load any PalmOS app you wanted onto. We had that... about 20 years ago.
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.
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...
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…
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.

25 years after the introduction of the 32 bit Intel i386 CPU, all Intel compatibles still start up (and wake up!) in 16 bit stone-age mode, and they have to be switched into 32/64 bit mode to be usable.
Apple's first product was the Apple-1 computer, introduced exactly 46 years ago, on April 11, 1976. This early microcomputer used an unus...
This is the BliKVM PCIe, a full computer on a PCI Express card. This is an IP KVM (Internet Protocol Keyboard-Video-Mouse) that can be put inside another computer or server. Most server motherboards already have remote 'lights-out' management functionality built in. Most frequently this is referred to as IPMI…
The landing gear and flaps indicator, control board stack, and C# .NET Windows Forms app running on the Surface in the background. Everything set for smooth and level flight!
A friend of mine recently brought up his custom mechanical keyboard while we were hanging out in voice chat, and at first, nobody understood why anyone would buy one. At that time, I had no clue that there are entire communities about building custom keyboards. With every sentence that was said, we got deeper into…
The Meshtastic is my solarpunk dream—a cheap, encrypted, offgrid communicator. But the project is still in the alpha stages (and it shows).
The Yamaha DX7 digital synthesizer (1983) was the classic synthesizer in 1980s pop music. It uses a technique called FM synthesis to produ...
