Reverse Engineering the Comtech AHA363 PCIe Gzip Accelerator Board
All this work was done in November last year. I haven’t worked on it since, but others have shown interest in picking this up, so it’s about time this gets thrown out in the open.

Tensorflow on edge, or – Building a “smart” security camera with a Raspberry Pi
The amount of time my outdoor cameras are being set off by light, wind, cars, or anything other than a human is insane. Overly cautious security cameras might be a feature, but an annoying one at that...

Logic, Before ICs
When integrated circuits were too expensive for common hobby use, we had to build digital logic out of discrete transistors.

Wireless Is a Trap
Over and over again, I’ve seen people fix some wireless-related problem and go “wow, I had no idea how much better this could be!" • Wireless protocols often silently operate in an extremely degraded state that makes them substantially worse than wired equivalents.

Restoring and MIDI-Fying a Baby Grand Piano
As much as I love digital instruments, synthesizers and other electronic gear I also really love the look and feel of instruments made from wood, brass, steel and felt. There is objectively no difference between the best digitally sampled pianos but for some reason it doesn’t quite feel as much alive as an actual…

I Replaced My MacBook Pro with a Raspberry Pi 4 8GB for a Day
Earlier this week, as part of my work doing a more complete review of the Raspberry Pi 4 (coming soon!), I decided I'd go all-in and spend one entire day working entirely (or at least as much as possible) from a Raspberry Pi. And not just doing some remote coding sessions or writing a blog post—that's easy to do on a…

Lamphone: Real-Time Passive Sound Recovery from Light Bulb Vibrations
Recent studies have suggested various side-channel attacks for eavesdropping sound by analyzing the side effects of sound waves on nearby objects (e.g., a bag of chips and window) and devices (e.g., motion sensors). These methods pose a great threat to privacy, however they are limited in one of the

Way to keep your cool running a Raspberry Pi 4 (2019)
From home temperature monitoring to a Kubernetes cluster hosting a live Drupal website, I have a lot of experience running Raspberry Pis. I've used every model through the years, and am currently using a mix of A+, 2 model B, and 4 model B Pis. The 3 model B+ was the first generation that had me concerned more about…

Discret 11, the French TV encryption of the 80s
I spent my childhood in France, playing a lot of soccer and watching way too much TV. In the 80s, there were three channels available. Two of them, Antenne 2 and FR3, were state funded and boring while TF1 was privatized and offered plenty of Japanese cartoons. My generation grew up with Captain Tsubasa, Saint Seiya…
