I have a love-hate relationship with ad blockers. On the one hand, I despise the obnoxious ads that are forced down our throats at what seems like every turn. On the other hand, I appreciate the need for publishers to earn a living so that I can consume their
One day there will hopefully be a house on this land Over the last year, I admittedly haven’t used my Vision Pro a ton, but fairly recently I discovered a super handy use that it’s absolutely incredible at, provided you have the right tools. After years of apartment life my girlfriend and I have recently begun the…
In 2020, Apple released the M1 with a custom GPU. We got to work reverse-engineering the hardware and porting Linux. Today, you can run Linux on a range of M1 and M2 Macs, with almost all hardware working: wireless, audio, and full graphics acceleration.
This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh .
In this project, I started to reverse engineer payment card terminals because they seemed to be an interesting target for security research, given the high stakes involved. Although I initially didn’t know much about this industry, I did expect a ton of security features and a very security-hardened device. And to…
The first episode of the Mojoptix video podcast: the invention of a Digital Sundial !
Deep dive into mechanical design that is optimized for 3d-printing.
Building in consumer hardware as a software engineer
Over the past week the station has been dedicated to an S-band scan looking for new targets and refreshing the frequency list, triggered by the recent launch of the mysterious ZUMA mission. This t…
A while ago, I put 16 GB of RAM into one of my computers. The computer is using a Foxconn P55MX motherboard with a Core i5 750. It’s old and could probably be replaced, but it still works for what I need.
Did you buy the new MacBook or MacBook Pro? Maybe the Google Pixel? You're about to enter a world of confusion thanks to those new "USB-C" ports. See, that simple-looking port hides a world of complexity, and the (thankful) backward-compatibility uses different kinds of cables for different tasks. Shoppers have to be…
Meet the ZedRipper – a 16-core, 83 MHz Z80 powerhouse as portable as it is impractical. The ZedRipper is my latest attempt to build a fun ‘project’ machine, with a couple of goals in mind:
Building a fully functional Linux handheld computer for under $15, featuring a custom PCB design, minimal BOM cost, and practical usability
After buying a new Philips Sonicare toothbrush I was surprised to see that it reacts to the insertion of a brush head by blinking an LED. A quick online search reveals that the head communicates with the toothbrush handle to remind you when it’s time to buy a new one. From the Philips product page: seems to be REALLY…
One of my favorite books is 2013 "High Performance Browser Networking" by Ilya Grigorik. Besides a wealth of actionable advice, the book is illustrated with captivating real life stories.
Speaking of being on the internet and finding things that make you go, “Hey! It’s not just me!” I scrolled across this skeet from Tyler Gaw : I just dug to the…

So, I'm walking through a park when I see this thing lying on the ground: It's a disposable vape that someone has discarded because it's emp...
The QuadRF (pictured above) a phased-array radio built around a Raspberry Pi 5 and an FPGA board with picosecond-level timing. It does advanced signal processing and beamforming. It can see WiFi through walls and track drones in flight. If the open source community can come up with something like this, just imagine…
My favorite internet service provider, init7, is rolling out faster speeds with their infrastructure upgrade. Last week, the point of presence (POP) that my apartment’s fiber connection terminates in was upgraded, so now I am enjoying a 25 Gbit/s fiber internet connection!
If you look at “gaming" keyboards, a lot of them sell for $100 or more on the promise that they’re fast. Ad copy that you’ll see includes:
Or running Gemma 4 on a 2016 Xeon with no GPU, 25 flags, 128 GB of DDR3, and a 25B-parameter MoE.
The death of hardware store optimization.
