[TriEmbed] Wireless radio communications for microcontrollers

[Pete Soper]

Apropos this subject, ARRL Field Day recently went by, and around that 
time Chris Gammell of The Amp Hour interviewed a slew of people during 
Toorcamp <https://toorcamp.toorcon.net/>, an offshoot of Toorcon that 
has a very heavy radio bent although it's primarily security-oriented. 
Chris is tentative and even apologetic about the unusual interview 
format (e.g. interesting, but not distracting background noises, 
subjects even more tangential than usual). But I think this series is 
absolutely terrific. Several of the interviews are of folks at the 
cutting edge of the hobby radio field (e.g. creators of HackRF).

The latter half of one interview is especially relevant for both 
beginners and folks trying to teach beginners. It starts at 19:15 here:

Finally, although not about radio, theAmp Hour interview of Jeri 
Ellsworth 
<https://theamphour.com/394-jeri-ellsworth-and-the-demise-of-castar/> is 
worth the time if you're interested in female role models. (and also 
Chris' interview of the two hackster.io ladies sailing Chris to the camp 
<https://theamphour.com/397-1-an-interview-with-monica-houston-and-alessandra-nolting/>).
