My first computer was a Texas Instruments TI-99/4A. Longtime readers may remember a previous article where we implemented TI-99/4A BASIC as a Scripting Language for modern computers. Recently I got nostalgic for the actual hardware so I got my 99 out of the closet where it had been for a decade o…
I've stumbled across a technique for drawing holograms directly upon a plastic plate by hand. It sounds impossible, but I've been sitting on the livingroom sofa making holographic images of floating polyhedra, words, 3D starfields, opaque objects, etc. No laser, no isolation table, no darkroom, no expensive film…
Last week’s adventures with the Exidy Sorcerer led me to write a Z80 version of the LZ4 decompressor I’d previously used on the SNES, the CoCo, and the Genesis. At this point, this has …

In 1980, Intel released the Intel 8087 floating-point coprocessor, a chip that could make math up to 100 times faster. As well as arithmetic...

I got the following e-mail from a producer/engineer: “I just want to try and alert you to the potential seismic scam happening with this Atmos roll out. Â Atmos catalog remixing is being done…
The convoluted and ultimately pointless tale of how I connected a retro 80s 5" BW TV to my PC as a 3rd monitor
Part 1 of the story of Motorola's 8-bit microprocessor design
If you often get static electricity shocks when touching your laptop or your office chair, or your monitor goes black when you stand up, this may interest you.
I was happy with the Remarkable 2 and when the Remarkable Pro came out I decided to go with a second one in order to be able to see two pages at once : one as a reference for reading and one for writing, as one would normally do with paper. Expensive approach, I know.
The noise floor is a lot lower in the forest
The most interesting keyboards I ever acquired

[Edit] This post sparked a conversation on Ycombinator ! I am concerned about Apple's move to its own home-grown processors. It's not because I'm worried about the new silicon, or Apple's ability to make high-performance CPUs, or even because I am worried about changing architectures. I survived…
Outside of a very few specialized fields high-security locks are almost totally unknown. Even in the field of locksmithing where high-security locks are known, they are often misunderstood. Today I am going to offer you a primer on the fascinating world of high-security mechanical locks, the securit
I needed to log when a light switched on and off during the night as part of debugging an oddly behaving movement sensor. To do that I built...
