Is This The Year Of The Linux… Television?

September 6, 2026 by No comments

The Year of the Linux Desktop hasn’t been on its way for quite as long as nuclear fusion plants, but somehow it seems to recede into the horizon at just about the same rate. Every year, it’s another year in the future. You know what isn’t a desktop? A television. [Haggis on Toast] makes a case that while there may be barriers to desktop adoption, there’s no reason not to use Linux for a set-top box, and shows one such build in a recent YouTube video.

This Clavichord Is A Well-Tempered Project

September 6, 2026 by 3 Comments

The Clavichord needs no introduction to fans of Early Music, and a lengthy one to literally everyone else. Even classical music buffs who have heard of Bach’s works for the “Well-Tempered Clavier” — another word for clavichord — will mostly have heard them performed on Piano. That is perhaps fitting, as the clavichord is a distant ancestor of the modern piano. It has keys — though fewer of them than a piano — whose action strikes strings — though much, much fewer of those than a piano, as each string is required to generate multiple notes. [Ian Summers] has an excellent guide on how he built his, though be warned that that link goes to a PDF and the SSL certificate was having problems as of this writing. If you aren’t comfortable grabbing a PDF over old-style HTTP, we’ve embedded the demo/build video below so you can give a listen to what this pre-piano instrument sounds like.

Printing Micron-Scale Benchies With Resin And Turmeric

September 6, 2026 by 2 Comments

Resin 3D printing has opened up a whole new scale of resolution for hackers, but the technology can go still finer; commercial micro-SLA and two-photon polymerization printers can print items with sub-micron feature sizes, but the machines are well out of reach for hackers. There’s more than one way to get such high resolution, though, as [Diffraction Limited] demonstrated with his micron-scale resin printer.

The printer builds on [Diffraction Limited]’s previous micro-manipulator and fiber-coupled laser. The micro-manipulator holds the end of the optical fiber just in front of the build plate, which is coated with resin. A 405-nm laser shines through the fiber, curing the resin in a narrow cone in front of the fiber’s core, which the micro-manipulator can trace in a pattern to build up objects, much like an FDM printer. Since the fiber’s inner core is only three microns across, the cured resin shears cleanly away from it when the fiber moves. Since the principle is so similar to an FDM printer, a standard slicer could be used to generate the tool paths.

WordStar Lives Again (and Again)

September 6, 2026 by 11 Comments

Word processors and editors are a funny thing. It doesn’t really matter what’s “best,” whatever that means. If you have finger memory built up for one program, it’s painful to change. That’s why most of us don’t learn how to type on a Dvorak keyboard and why [George R. R. Martin] writes with WordStar. Many people of a certain age have a deep memory of WordStar. Now you can run it on a modern machine or even in your browser without a lot of trouble, thanks to [nampara-ai].

The idea is simple. Take a vintage copy of WordStar for MSDOS, wrap it with DOSBox, and package it up with some basic scripts for Linux, Mac, or Windows. In addition, there’s a WebAssembly version for the browser if you’re into that sort of thing.

There’s Whole Computer Inside This Mouse

September 5, 2026 by 5 Comments

[Gadget Industry] bills it as “a PC inside a Mouse“, but that depends on your definition of a “PC”. This is a Personal Computer inside a mouse, yes, but there’s nothing IBM-compatible about the tiny ARM board he squeezes inside what’s normally a peripheral — it actually started life as a smartphone, which only takes this build up a notch compared to starting with a single-board computer like a Pi.

Specifically, he starts with a Galaxy S21 5G. Starting with a Samsung means he can leave the stock Android alone and just take advantage of Samsung’s DeX desktop mode, rather than layer a Linux environment on top or replace the operating system entirely with something like Postmarket OS, which are both viable options.

Can AI Now Design PCBs That Just Work?

September 5, 2026 by 34 Comments

With the recent release of its GPT-6 Astra model, OpenAI explicitly pushed the claim that it is capable of designing complete circuit boards in KiCad, starting from a provided schematic and outputting a fully routed PCB that theoretically could be sent off to be manufactured. This of course raises the question whether this is just a nifty party trick that works under strictly controlled conditions like most auto-routing tools, or whether there’s more to it. In a recent [EEBench] blog post, OpenAI’s claims are put to the test.

Running Apple ][ Software On A Commodore 64 — Silently

September 5, 2026 by 5 Comments

The computer business in 1984 was a bizarre mix of hobby-level companies, a few small companies that had made it big, and a lot of big companies starting to take notice of personal computers. Plenty of money followed, which led to strange products and even stranger ads. [Such Bad Tech Ads] reveals a very bad ad from that time for a product we have barely heard of: the Spartan. The Spartan’s job was to convert your Commodore 64 so it could run Apple ][ software. The ad campaign had, inexplicably, a mime. We think. Or maybe a clown. Hard to say.

On the face of it, the Spartan might not be a bad idea. In 1984, there was plenty of Apple software. Well, relatively, anyway. But a Commodore computer was far cheaper. Other conversion kits like the Intel Inboard/386 managed to find some success in the market later. The problem, outside of strange ads, was one of timing.
