Hello mastodon.radio ! This is an #introductions , as requested.
I recently returned to Mastodon after hearing about this instance on a different site. I'm really passionate about electronics, robotics, and promoting diversity in amateur radio/promoting the hobby among other teenagers.

Power poles, 12v -> 24v buck converter into a passive POE injector for a Ubiquity node running AREDN. Much less current draw than the small inverter I used before. Hopefully this won't flog the HF bands with QRM. #powerpoleeverything
The Western Electric Type-B, 100-point, 6-wire telephone crossbar switch (1970). An invention from a century ago, back when switches had coils and magnets, not ifconfig, ethtool or netfilter, it was where the idea of the keyboard matrix, matrix ROM and LED matrix originally came from, the same topology is also used for interconnection in multiprocessor computer systems. #retrocomputing #electronics
