Reverse engineering the 1988 NeXT keyboard protocol

Summary : Steve Jobs's NeXT computer company made a keyboard in 1988. With no prior electronics experience, I tried to get it to work over USB. To do so, I had to go way deeper than I ever expected - all the way back over 100 years to broadcast radio standards from the 1920s. I learned tons and tons, and had a lot of…

An M1 for Curl

A generous member of the wider curl community stepped up and donated an unused Mac mini m1 model to me to be used for curl development. Today it arrived at my home. An 8C CPU/16GB/1TB/8C GPU/1GbE model as per the sticker on the box. The m1 mac mini, still wrapped in plastic. Apple is not … Continue reading An m1 for…

My thoughts on the Framework laptop

Like many others in the open source community, I was very intrigued by the idea of the Framework laptop , a modular laptop designed to be repairable and upgradable. With a bunch of designs, schematics and documentation released as open source and a product that's legitimately competitive with the proprietary…

Hijacking infrared to make a dumb device smart

I own a very old ‘flat’ screen television from 2009. One of the reason this TV is still kicking around is because I have a strange sentimental affection for it. Another is that I have written automation for it that works really well and it would be a pain to migrate away from it.

Linux on a 486SX

Linux on a 486SX A year or two ago, I came into posession of a 1993 Compaq Presario 425. It's a Mac-ish all-in-one with a 14" color (S?)VGA screen capable of 800x600 in full 256-color glory. On the inside it features a 25MHz i486SX (the sort without a floating-point unit), paired with 20MB of RAM - a significant…

The death of the PCIe expansion card

With the AM5 platform from AMD on the horizon, five major motherboard manufacturers have annonced their flagship motherboards with the X670E chipset. Some of them are having fun with this generation’s multi-faceted step into “five”: AM5, PCIe Gen 5.0, DDR5, 5nm process, boost clocks over 5GHz, you catch the drift. But…

Ghost in the ethernet optic

A few months ago I stumbled on a tweet pointing out a kind of SFP optic that claimed to be smart, made by a Russian company Plumspace . After going through their Smart SFP product listings I was on-board and decided I needed to have some of them.

Why Apple Will Switch to ARM-Based Macs (2014)

When Steve Jobs announced the transition from PowerPC to Intel processors in 2005, he revealed something that, in hindsight, seemed obvious to everyone who didn’t anticipate the switch: There are two major challenges in this transition. The first one is making Mac OS X sing on Intel processors. Now,

My Unholy Battle with a Rock64

I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them. Well, except NetBSD, but NetBSD…
