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…

Make your electronics tamper-evident
If the police ever have physical access to an electronic device like a laptop, even for five minutes , they can install hardware keyloggers, create images of the storage media, or otherwise trivially compromise it at the hardware, firmware, or software level. One way to minimize this risk is to make devices…

Programming a CH32v003 with light
A comedic example, parked nicely on the thinnest wedge of the venn diagram, is the HamFurs – people who do amateur radio while wearing fur suits. While it isn't my cup of tea, I love that such a group exists. They seemed like nice people when I chatted to them.

Reverse-engineering my speakers' API to get reasonable volume control
I got some fancy new speakers last week. They’re powered speakers and they have streaming service integrations built in, unlike the 35-year-old passive speakers I’m upgrading from. Overall they’re great! But they’re so loud that it’s difficult to make small volume adjustments within the range of safe volume levels for…
