The author of "The Secret Life of Circuits" created 290 original illustrations by gathering real data for electronics components, including quartz crystals, batteries, and vacuum tubes. To measure semiconductor devices, the author used a benchtop multimeter and pulsed power from a lab supply, interfacing them to a computer using the SCPI protocol to capture accurate V-I curves.

Regressive JPEGs

https://maurycyz.com/projects/bad_jpeg/cats.jpg
The post explains how JPEG progressive scans can be used to progressively display low‑frequency data, and how the author exploits this by concatenating multiple scans (mostly DC‑only) to create a pseudo‑animation that works in browsers up to about 90 frames. Although this trick bypasses the usual 9‑scan limit and avoids ghosting, it has no real practical use because timing must rely on ...
