Programming a CH32v003 with light
A comedic example, parked nicely on the thinnest wedge of the venn diagram, is the HamFurs – people who do amateur radio while wearing fur suits. While it isn't my cup of tea, I love that such a group exists. They seemed like nice people when I chatted to them.

Reverse-engineering my speakers' API to get reasonable volume control
I got some fancy new speakers last week. They’re powered speakers and they have streaming service integrations built in, unlike the 35-year-old passive speakers I’m upgrading from. Overall they’re great! But they’re so loud that it’s difficult to make small volume adjustments within the range of safe volume levels for…

Back to the future: Are hackers the future of amateur radio?
Last fall, under the aegis of Ham Radio Village , I was awarded a grant to take my one-day Tech class on the road. Ham Radio Village believes that more people in technical fields should have amateur radio licenses and that amateur radio is underrepresented in the hacker, STEM/STEAM, and maker communities. Currently…

Decoding DME aircraft radio navigation system with the LimeSDR
DME (distance measuring equipment) is an aircraft radio navigation system that is used to measure the distance between an aircraft and a DME station on ground. DME is often colocated with a VOR station, in which case the VOR provides the bearing information. DME works by measuring the two-way time of flight of pulse…
