I often get distracted. I obviously don’t like it. So I decided to turn my computer’s clock into a constant reminder to help me focus. Implementation This hack requires: Ubuntu with GNOME desktop environment The Panel Date Format extension A simple bash script 1. Install the Panel Date Format extension # If you don't…
The other day I saw the announcement for the new Chrome OS test laptop and decided to sign up on the off-chance that I might be able to snag one. In the request form I made it very clear that I would be attempting to use this laptop for development (easily my primary activity). Surprisingly the laptop arrived this…
How I upgraded my Macbook's Thunder2 eGPU from a bus-powered GTX 1050 Ti SC to a PSU-powered GTX 1080.
Instructions on how to design, calculate and build power transformers.
Programming PIC32 Microcontroller with Rust, AKA running rust on bare metal
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
In my last post, I showed you to use FireWire on a Raspberry Pi with a PCI Express IEEE 1394 adapter. Now I'll show you how I'm using a new FireWire HAT and a PiSugar3 Plus battery to make a portable MRU, or 'Memory Recording Unit', to replace tape in older FireWire/i.Link/DV cameras. The alternative is an old used…
I have been meaning for a while to establish a setup to implement neural network based algorithms on smaller microcontrollers. After reviewing existing solutions, I felt there is no solution that I…
A few months ago I introduced you to one of the more notable Apple pre-production units in my collection, a late prototype Macintosh Porta...
Nowadays, there is increasing interest in adding tagged memory functionality to CPU architectures. Such architectures associate one or more tag bits with each quantum of a system's memory. There are many motivations for this ability to associate “metadata” with individual memory words, but one of the most clear is the…

Rockwell famously used 6502-based cores in modems for many years, but that doesn't mean other 6502s couldn't be used. If only there were a w...
A couple of months ago I stumbled upon a post on Hackaday about an inexpensive open-source USB 2.0 sniffer created by Alex Taradov . This is a really cool project! Normally, USB sniffers like this can cost thousands of dollars, especially if you’re paying for fancy protocol decoding and also want high-speed 480 Mbps…
Long-time readers will know that my first video game love was the text-mode video game slash creation studio ZZT. One feature of this game is the ability to ...
DPReview just published Apple still hasn't made a truly “Pro” M1 Mac – so what’s the holdup? Following on the good performance and awesome power efficiency of the Apple M1 , there’s a hungry background rumble in Mac-land along the lines of “Since the M1 is an entry-level chip, the next CPU is gonna blow everyone’s…
Last year I started collecting ideas of things I would like to 3D print one day, on Twitter. Twitter is fundamentally ephemeral, so I'll collect it here instead. I got up to 14 items on Twitter, and now I'm up to 25.
So you decided to build a brand new system using all the latest and coolest tech, so you buy a Ryzen 7000 series Zen 4 CPU, like the Ryzen 7700X that I picked, with a new mother board and DDR5 memory
Disclaimer: this, by no means, is not a definitive description of the whole embedded-specific development. This is just a small good practice about interaction with hardware.
This blog post shows how to create a reliable and realistic-looking malicious USB key that can be used in a drop attack.
We traded the physical boundaries of dedicated rooms for the convenience of our always-on digital lives -- but recently I've been building those walls back up.
Today Raspberry Pi Trading announced the Raspberry Pi 400, the latest in the series of small education-focused computers that started with the original Raspberry Pi in 2012. For years, people have come up with creative ways to hack a Pi into keyboards, like the Original Pi in an old Mitsumi keyboard, or the Pi 3 A+ in…

Ambient lighting is a technique that creates light effects around the television that correspond to the video content. It has been pioneered...
I do a lot of electronics projects in my spare time, and I tend to try to make reusable parts to save myself effort in the future. Because I have to order ingredients in certain quantities, I often wind up with more than I need for my project.
With separate plastic, metal, paper, and glass recycling, composting, and pick up of all the rest, knowing which days to put out which bins ...
A Do it Yourself project to help remove dust particles in your room. A completely open-source hardware project which you can download and use for free.
Back in 2015, I had the idea for gpiozero — a Python library for Raspberry Pi, making programming GPIO devices simpler by abstraction: instead of thinking about pin channels, voltages, pull-up resistors and rising or falling edges, we think about buttons being pressed and released, sensors...
