Strain gauge made out of PCB (github.com/vapetrov)
A strain gauge, with amplifier, where the sensing element is the circuit board itself. Sensitive enough to measure deflections in the range of micrometers while having a full scale deflection range of +/- 3cm.

A Tektronix TDS 684B Oscilloscope Uses CCD Analog Memory (tomverbeure.github.io)
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. It can only record 15k samples per channel at a time, for example.

Switch bouncing reference traces for a variety of different switches (github.com/gsuberland)
This repository contains a collection of example traces showing switch bouncing behaviour. This may be useful if you want some quick reference data for implementing robust debouncing systems in your circuits and firmware.
Retro Computing (hansotten.nl)
This page is about my interest in retro 8-bit small computer systems computing and electronics. And the role of Dutch electronic magazines like Elektuur and Radio Bulletin in the eighties of the 20th century. Also the Dutch users club, called KIM Gebruikersclub, which I joined in 1978 and contributed to as member of the board and as chief editor of the magazine issue 11 to 25.

The many ways tarrifs will hit electronics (ieee.org)
Like the industry he covers, Shawn DuBravac had already had quite a week by the time IEEE Spectrum spoke to him early last Thursday, 10 April 2025. As chief economist at IPC, the 3,000-member industry association for electronics manufacturers, he’s tasked with figuring out the impact of the tsunami of tariffs the U.S. government has planned, paused, or enacted. Earlier that morning he’d recalculated price changes for electronics in the U.S.

My Approach to Teaching Electronics (lcamtuf.substack.com)
On occasion, I quip about the way we teach electronics to hobbyists. We start with hydraulic analogies that compare electricity to water running through pipes. I think it’s a pretty bad teaching tool, but don’t close the tab just yet: today’s article isn’t going to be about the dubious scholarly credentials of Mario Bros.
