A Tektronix TDS 684B Oscilloscope Uses CCD Analog Memory
I have a Tektronix TDS 684B oscilloscope that I bought cheaply at an auction. It has 4 channels, 1 GHz of BW and a sample rate of 5 Gsps. Those are respectable numbers even by today’s standards. It’s also the main reason why I have it: compared to modern oscilloscopes, the other features aren’t nearly as impressive…

Binary modding a water dispenser to save me from pressing a button (2021)
A few months ago, I decided that it’s time I started to become more responsible and to start drinking more water. Unfortunately, the tap water where I live has a very high calcium content, which makes it a lot better when filtered and cooled first. To solve both issues, I picked up a second-hand professional water…

Why doesn't Apple make a standalone Touch ID?
I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in. But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an…

$5 whale listening hydrophone making workshop
Whale songs were first noticed by accident, when analysts tracking Russian submarines at the height of the cold war heard cetacean interference instead. An engineer sent some recordings to Roger Payne, a biologist friend of his, who did something that proved pivotal: he played the hours-long recordings on his hi-fi at…

Vetinari's Clock (2011)
In the excellent Discworld series the character Lord Vetinari has a clock in his waiting room which is designed to tick irregularly in order to make his visitor feel ill at ease. Inspired by a post featured on Hackaday I decided to build my own version of this clock with a simple and easy to make design.

Minisforum Stuffs Entire Arm Homelab in the MS-R1
The Minisforum MS-R1 uses the same Cix CD8180 Arm SoC as the Orion O6 I reviewed earlier this year. But everything else about this thing is different. What this thing should be, is a box that runs Linux and can compete with at least an Apple M1 Mac mini, or a mid-range Mini PC. But what we got... is something…

DIY PTP Grandmaster Clock with a Raspberry Pi
tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially…

The Qweremin
In the summer of 2022 I built a C64-based theremin, described and explained here . The theremin, of course, is one of the oldest electronic instruments. Its main drawback—and strength—is that it's incredibly hard to master. The performer has ultimate control over volume and pitch, but it takes months of practice…
