From b568b91b90684e577231611b61fb51a3790e418a Mon Sep 17 00:00:00 2001 From: Jon Froehlich Date: Wed, 24 Jun 2026 08:58:34 -0700 Subject: [PATCH] Consolidate electronics/assets/gifs/ into videos/ (follow-up to #119/#120) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After #119 converted the electronics GIFs to MP4, the `gifs/` dir held only `.mp4` files — a misnomer, and electronics already has a `videos/` dir. Consolidate onto `videos/` for consistency with the #120 movies/->videos/ standardization: - git mv the 3 .mp4s from assets/gifs/ into assets/videos/ (no collisions) - relocate the one orphan (unreferenced) diagram, electric-current- flows-downhill-lower-voltage.png, to its proper home assets/images/ - update the 4 `assets/gifs/` refs (electricity-basics.md x3, resistors.md x1) to assets/videos/ - remove the now-empty assets/gifs/ dir Verified: jekyll build clean; built _site/electronics has no assets/gifs/ refs and the moved videos resolve. link-check CI gate is the backstop.

In the animation above, we are illustrating "electron flow" as a dotted green line, which flows from the negative terminal of the 9V battery, through an LED and resistor, and then back to the 9V battery to its positive terminal. Note that this is actually opposite from *conventional current* flow, but we'll get to that below.
