The final result is concealed entirely within the fan’s housing, leaving no visible modification.</p> <p> If you’re interested in building one yourself, the schematic, BoM, and PCB design are all available here. In terms of firmware, I used ESPHome with an external component, for which the source code is available here. The rest of this post covers the research and development that went into the project.</p> https://ellis.codes/blog/my-fan-worked-fine-so-i-gave-it-wi-fi/ 2025-11-12T08:22:31Z 2097 https://ln.ht/~2097 <p> Oh, nice, AO3 has an epub export.</p> https://archiveofourown.org/faq/downloading-fanworks 2024-03-07T23:28:03Z wyclif https://ln.ht/~wyclif http://articles.marco.org/143 2013-08-04T05:08:50Z
