As seen on Hackaday! TL;DR – The SanDisk High Endurance cards use SanDisk/Toshiba 3D TLC Flash. It took way, way more work than it should have to figure this out (thanks for nothing, SanDisk!…
Finding and exploiting bugs in the Xbox 360 hypervisor to create the "Bad Update" exploit.
My favorite memory of my M1 Pro MacBook Pro was the whole sensation of “holy crap, you never hear the fans in this thing”, which was very novel in 2021. Four years later, this MacBook Pro is still a delight. It’s the longest I’ve ever owned a laptop, and while I’d love to pick up the new M4 goodness, this dang thing…
Sharing my thoughts and current projects.
76/300 Pocket Dobson: a tiny yet real telescope that comes with you everywhere
In the past few years, CPUs have gotten really fast. Shockingly fast! Yet most people are stuck on previous generation mobile chips (whether by choice, or by their companies choice), at a huge detriment to their productivity. Meanwhile, AI coding subscriptions like Cursor are all the rage these days. I'll skip the…
About 5 months ago I made the decision to start self hosting my own S3 . I was working on AppGoblin’s SDK tracking of the top 100k Android and iOS apps so was wanting a lot of space, but for cheap.
We will explore how we can use an Android E-ink tablet (or any tablet) as a monitor for Linux computer
I bought a MacBook Air M2. As of writing, it's very affordable with the 16 GB RAM, 256 GB SSD, 13.6" model available for $750. As of writing, also Asahi Linux doesn't support anything newer than M2.
Configuring PipeWire to make laptop speakers sound better (Bankstown, Convolution/FIR, etc.)
Using a decommissioned Alibaba cloud accelerator card as an FPGA dev board
100x More Efficient than Arm?
I have been using a MacBook Pro M4 as my portable computer for the last half a year and wanted to share a few short impressions. As always, I am not a professional laptop reviewer, so in this article you won’t find benchmarks, just subjective thoughts!
Claimed end-to-end privacy doesn’t fully conceal your rear-end data
Especially if you want it to work.
Recently I undertook a hobby project to recreate an IBM XT Personal Computer from the 1980s using a mix of authentic parts and modern technology. I had a clear goal in mind: I wanted to be able to …
Apparently shlx is a “medium latency” (3 cycles) instruction on Alder Lake. My disappointment is immeasurable, and my day is ruined.
The GPU in your computer is about 10 to 100 times more powerful than the CPU, depending on workload. For real-time graphics rendering and machine learning, you are enjoying that power, and doing those workloads on a CPU is not viable. Why aren’t we exploiting that power for other workloads? What prevents a GPU from…
The bizarre story of how taking flash photos could instantly crash the Raspberry Pi 2, the community detective work that solved it, and why this strange bug revealed fundamental flaws in modern chip design.
These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space…
The Cinema Industry is using its own standards for creating and distributing movies in a secure way. The DCI (Digital Cinema Initiatives) specification defines everything from file formats and encryption to the projection systems itself.
My smart bike company went bankrupt, so I added a physical button to turn the light on/off
Ever wondered why 100nF is a go-to value for decoupling capacitors? This number has pervaded in datasheets and electronics advice going back to the 1980s, and is still widely present in the datashe…
I’m sure I’m not the only one who feels Apple’s quality is degrading. I spend 10 hours a day on my laptop and would spend any amount of money within reason for a better one. However, everything comes with tradeoffs.
Some broadcast engineering tasks are a bit too daunting for me to consider. Climbing the massive towers that power radio and TV stations is one of them! Your browser does not support the video tag. Recently, local engineer Aaron Cox had the perfect set of conditions for a drone flight to capture some of that risk, as…
2023-01-01: This project has been ongoing for a while... now its time to post some of this info and see what comes of it. I have access to several junk Milwaukee M18 batteries. Age varies a little. I thought it would be 'fun' to reverse engineer a battery just to see how it functions... That is until I actually opened
How I went about creating a concealed modification for a fan so I could control it over WiFi with ESPHome and Home Assistant.
