Air Con: $1697 for an on/off switch
Forcing customers to replace an entire system just because the cheapest component failed might be really profitable, I have no idea… But I do know that it annoyed me enough to make me want to fix it myself.

Bit-banging a BASIC Birthday
I spent this summer building a new app, for a machine that hasn’t been on the market since 1980 and wasn’t built to support graphics, sound, connectivity or even lowercase letters, sold by a company that went bankrupt a decade ago, tailor-made for an audience of one: my dad, who celebrated his 70th birthday this past…

The Apple IIGS Megahertz Myth
I love the Apple IIGS. It’s a great computer, but could it have been greater? The legend goes that Apple purposefully underclocked its CPU during development to avoid competing with the Macintosh. But is this actually true? Join me for a deep dive into the IIGS architecture, the life the 65816 CPU,

DARPA wants to bypass the thermal middleman in nuclear power systems
Nuclear power already has an energy density advantage over other sources of thermal electricity generation. But what if nuclear generation didn’t require a steam turbine? What if the radiation from a reactor was less a problem to be managed and more a source of energy? And what if an energy conversion technology could…

How to talk to your parents about hardware memory safety
Some conversations are difficult to have with members of older generations who grew up with different social norms. In particular, when you’re talking to people who grew up with PDP-11s with their completely flat memory, or Lisp machines or Burroughs Large Systems with their deeply opinionated and language-integrated…

A Better Light Source for Scanning Color Negative Film
Narrowband trichromatic (RGB) light sources are superior to broadband (white) light for scanning color negative film; there are very good reasons why all commercial film scanners use RGB. ( film scanners were using blue LEDs at least a decade before they would be widely used in consumer products! ) Scanning film with…

Replacing Liquid Metal on an Asus Zephyrus G15's CPU
I’ve been using the Asus ROG Zephyrus G15 as my daily driver for a few years now. Laptops (gaming laptops especially) pack a lot of heat-generating components in a small and thin space, where the only airflow comes from the small blower fans in the system. In the case of the Zephyrus G15, there’s approximately 120…
