1 I made a Self-Soldering Circuit
Shared as a curiosity showing boards whose own resistive traces heat up to soldering temperature, so they can solder their own components.

Shared as a curiosity showing boards whose own resistive traces heat up to soldering temperature, so they can solder their own components.
One of a YouTuber's experiments using circuit boards as heating elements, linked when people ask whether this works, with some doubt that board-based hot plates justify the trouble.
