I own a very old ‘flat’ screen television from 2009. One of the reason this TV is still kicking around is because I have a strange sentimental affection for it. Another is that I have written automation for it that works really well and it would be a pain to migrate away from it.
CT scans of a new and "empty" toner cartridge reveal a 5% operating window, an 80% air hopper, and the real reason shaking the cartridge always works.
Creating a quarter-scale replica of the iconic BeBox computer, complete with blinkenlights and custom case design
The internet is littered with explanations of how transistors work. Most of them don't really explain anything.
Is exFAT as fragile as some say?
Today, the Oceanic+ app comes to Apple Watch Ultra, turning Apple’s most rugged watch into a fully capable, easy-to-use dive computer.

Fans, an active cooling element, move air in a system. Heat must be removed from the site of its production, and from the system as a whole. A fan increases heat convection with surrounding air via airflow. Air is at its highest pressure immediately in front of the fan, and at lowest pressure immediately behind it.
I used Ghidra twice, so that means I'm officially an expert in reverse engineering
Lately I’ve been spending time on Mastodon for … reasons. Here’s my link: https://oldbytes.space/@blakespot. In my recently active time on the platform, I have found quite a few excellent retrocomputing-related posts by creative members of the community. One such post, … Continue reading →

The Rimac Nevera has set a top speed of 412kph (258mph), making it the fastest electric production car in the world.
Apple’s groundbreaking safety service Emergency SOS via satellite becomes available to customers in the US and Canada starting today.
If you know how to use a command line, you can build one
The 8086 microprocessor is one of the most important chips ever created; it started the x86 architecture that still dominates desktop and ...
Building a battery powered e-ink weather forecast display for our home. This was a fun Raspberry Pi project.
Rosetta 2 is remarkably fast when compared to other x86-on-ARM emulators. I’ve spent a little time looking at how it works, out of idle curiosity, and found it to be quite unusual, so I figur…
In August 1999, Apple announced the first Power Mac G4: 1 The Power Mac G4 is powered by the revolutionary new PowerPC G4 chip architected by Apple, Motorola and IBM, and is the first personal computer in history to deliver supercomputer-level performance of over one billion floating-point operations per second. The…
Ever since moving from NYC to SF to work at Anthropic I’ve been visiting NYC and working remotely quite often. So I designed myself a travel workstation that lets me get the best of ergonomics and packability.
I heard about VHS recently. It’s a tool for creating recordings of command-line tools, so you can create little demos and tutorials about how to use them. You can write a script to run comman…
NightWare, a digital therapeutic system that works with Apple Watch and iPhone, is offering relief to veterans experiencing nightmares and PTSD.
Where the last two posts were primarily about software ( Navidrome and beets , respectively), this post will be more about hardware (and a bit of software to control it). Hopefully it’ll be useful to others with older sound hardware, especially those who are compelled (as I am) to avoid buying a “connected” device…

Audio CD ripping - optical drive accuracy listing
CPUs like to operate on data types such as uint8_t , uint16_t , uint32_t , and uint64_t . These data types can be viewed as integers modulo 2 8 , 2 16 , 2 32 , and 2 64 respectively. Addition and multiplication can be defined on these integers modulo 2 N in a way which is familiar to most people; for example, in…
A look into the hardware design of Starfish
Taking pictures and geeking out over cameras was one of my first hobbies starting with an old Olympus point and shoot, I then moved up to a DSLR upgrading as new and exciting technology became acce…
