Hello!

This is an article I resisted writing for a long time.

When working on my latest book, The Secret Life of Circuits, I wanted to keep the artwork real.

Unusual clocks are a common idea for electronics DIY projects.

Last year, I published an article titled “It’s hard to build an oscillator”: The title alluded to the fact that there’s no shortage of oscillator circuits on the internet, but many of them use unusual parts, need weird supply voltages, or don’t work well…

Electronic circuit theory is a frequent theme on this blog.

Today, I’d like to talk about logic — and before I do, I should probably explain why.

Last week, I posted a visual demonstration of the sameness of AI-generated content.

One of the most painful arguments I keep having with fellow techies is the question of whether you can distinguish between human-written and AI-generated text.

Welcome.

Some folks say that the design philosophy of Unix is that “everything is a file”.

Back in 2019, I built a simple voltmeter clock: The clock, version 1.

Are you a C or C++ programmer?

Many of you follow this blog because of the regular features about electronic circuit design.

If you know about my professional background, the most puzzling aspect of this Substack must be that I don’t use it to talk about my primary field of expertise: information security.

A while back, I posted the following on social media: If you’re unfamiliar, Conway’s Game of Life takes place on a two-dimensional grid of square cells, each cell either alive (1) or dead (0).

I have a complicated relationship with Hacker News.
