I reverse engineered the hardware and firmware of my Egret GT E-Scooter. I describe how I got in, analysed communication between components, and reverse engineered firmware. I speak about writing custom firmware for the display unit.
My old 2016 MacBook Pro has been collecting dust in a cabinet for some time now. The laptop suffers from a “flexgate” problem, and I don’t have any practical use for it. For quite some time, I’ve been thinking about repurposing it as a guinea pig, to play with FreeBSD — an OS that I’d aspired to play with for a long…

A startup called Taalas , recently released an ASIC chip running Llama 3.1 8B (3/6 bit quant) at an inference rate of 17,000 tokens per seconds. That's like writing around 30 A4 sized pages in one second. They claim it's 10x cheaper in ownership cost than GPU based inference systems and is 10x less electricity hog…
My experience fixing my Framework 13” laptop with AMD 7060 series that was bricked due to a failed BIOS update with US$20 worth of tools, instead of replacing the motherboard as suggested by Framework support.

Almost a decade ago, I released a hackintosh guide on running macOS 10.14 through a VM with an x86 host. A "Hackintosh" is the feat of running macOS on non-Apple hardware, and has a history dating back to the late 1980s. At the time KVM and PCI
The Minibook X is a 10.5″ x86_64 sub-ultrabook with 16GB RAM, a 512GB NVMe drive, and only one majorly annyoing Linux quirk.
We turned a MacBook into a touchscreen using only $1 of hardware and a little bit of computer vision.
My nephew just graduated high school, and wants a laptop. When he decides what computer to buy, price (or more precisely, value) is the most important attribute. Apple's MacBook Neo upended the 'value laptop' equation—Apple's not supposed to be both the cheapest option and the best value... but it seems like that's…
Dmitry.GR: I am often asked to explain my distaste for RISC-V. Here it is.
So today I reached a nice milestone in one of my projects: my work porting classic Mac OS to PowerPC systems with what I affectionately call ArtX chipsets (Nintendo GameCube, Wii, eventually Wii U; the GameCube’s Flipper integrated chipset was very much designed by ArtX as it was effectively finished when ATI acquired…
Ok it’s not exactly $60 but you can get the board itself for that amount of money on eBay if you’re lucky, but on average the price is around $70-$100 (as of November 2025) which is still very cheap considering you can play Cyberpunk 2077 on this.
I love networking, a lot. So much so that I've run my own ISP since 2024, complete with its own ASN, IPv4/6 address space, fiber optics, etc. However, do this and you quickly realize how reliant you still remain on central service providers. The internet is a mesh,

My wife and I recently went on a 7 week holiday around Europe. Although we each took a massive backpack, we wanted to travel fairly lightly. I took a single universal power brick. This little unit was all I needed to charge my various gadgets. It has a hefty USB-C PD (Power Delivery) port for rapid charging of my…
