A while ago, a friend of mine turned 25 and held a fairly big birthday party. One of the things he wanted to serve were jello shots: basically little shot glasses of jello with alcohol mixed in. The consistency and sweetness makes for a pretty interesting drink, and he wanted to make 70 or so shots, at least one for…
Ever since the Pi 2 model B went to a 4-core processor, disk IO has often been the primary bottleneck for my Pi projects. You can use microSD cards, which aren't horrible, but... well, nevermind, they're pretty bad as a primary disk. Or you can plug in a USB 3.0 SSD and get decent speed, but you end up with a cabling…
I was having fun lately with some normal macro photography and was curious if I somehow can use my fathers microscope lenses on my photo and film cameras. The idea is not new, a quick google search showed that it was indeed possible but you need a special adapter for these microscope lenses. The adapter is called “RMS…
IBM used some unusual techniques in its integrated circuits, and one of the most visible is packaging them in square metal cans. I've been...
I’ve had my M1 MacBook Air for a bit of time now, and I also recently started mining Ethereum. I can’t help asking myself: What’s Ethereum mining performance like on a M1 Mac?
A series where I’m documenting my process of designing and building an e-ink laptop.
How do you boot a computer from punch cards when the computer has no operating system and no ROM? To make things worse, this computer req...
In this guide, I will explain how to receive SMS messages and forward them to your Telegram account using Raspberry PI Zero W and Wireshare GSM hat. Python will be used to read SMS messages and forward them to Telegram Bot API. Messages will be listened to by Gammu SMS service and it will trigger the Python script…
The quartz oscillator is an important electronic circuit, providing highly-accurate timing signals at a low cost. A quartz crystal has the...
Apple has revealed the hidden Fallback Recovery OS mode available on M1 Macs. How to enter and use it, and why it’s another big plus.
Collection of odds and ends relating to e-readers including personal reminisces Background # Reading has been a huge part of my life. The written word has had arguably more of an impact on my life than anything I have experienced in person. As a kid back in early 2000’s; this meant a lot of library trips and saving…
Because it’s a real mess to reinstall Big Sur!

Making an external bootable SSD for an M1 Mac has proved tricky. Has this changed in macOS 11.2? If you’ve already got 11.1 running on one, how do you update it to 11.2?
I fancied getting an eink screen to use for future projects. I bought a wee one with a raspberry pi "hat" attached. However, I realised later that I could maybe just re-purpose an old Amazon Kindle eb…
The Motorola MC14500B 1 is a 1-bit processor introduced in 1976. While a 1-bit processor might seem almost useless, 2 it was marketed as...
I made a Bluetooth trackball in which all the electronics are inside the ball. The ball is the entire trackball. Here it is in action: I...
I had wrote this before the Unleashed was revealed, so some of the bits on economics have changed. As of writing this, I still stand by my other beliefs. One of the most hyped things in hardware design is RISC-V,… Continue reading →

Wirecutter is obsessed with the humidifier that untold numbers of purchasers despise
I recently received a vintage IBM paperweight from the early 1970s that showcases some memory chips. 1 When IBM started using integrated ...
When most people hear Apple in a sentence, their next thought is likely the color. Does Apple Silicon M1 output “billion colors”?
TL;DR Modern disks are so fast that system performance bottleneck shifts to RAM access and CPU. With up to 64 cores, PCIe 4.0 and 8 memory channels, even a single-socket AMD ThreadRipper Pro workstation makes a hell of a powerful machine - if you do it right! Update 1: Since 2021, networks have gotten faster and now…
