Early in November, I saw an announcement of a local-to-me meetup group for my current hobby, software-defined radio, and requested presentation topics.
I saw an opportunity to get around to working on an idea that I’d had scribbled down for a while, so I went and did it. In about one weekend of programming and writing, I prepared my presentation, and here’s the video: “A Visual Introduction to DSP for SDR”.
I got a lot more praise for it than I was expecting. Besides the obligatory applause, people came up to me afterward to tell me how remarkable my visualizations were. And from Twitter afterward:
After I reviewed the video, I saw I’d flubbed my intro (I meant to follow up the “I have no credentials” speech with “so if I can do this, so can you”, but I forgot), though I managed a satisfactory amount of looking-at-the-audience-not-the-screen and lack-of-”um” — but, I think the content of my presentation would have made up for all of those mistakes if I’d made them.
And if you’re interested in digital signal processing, or if the Fourier transform is a mystery to you (that you want to solve), then you should watch my presentation.
(Also, in news of Being An Adult While Still Feeling Like You’re Faking It, as of this month I have successfully navigated two major upheavals this year in my previously-arranged-to-my-satisfaction life which could be broadly described as outside forces telling me “You won’t be able to keep that thing you currently have. Find a new one.” And I’m glad that worked out and I consider it a substantial accomplishment. But the above thing is considerably more awesome.)

“Coolest live 3D visualization of DSP concepts I’ve ever seen”
“Finally a good 3D visualization example for complex valued waveforms!” — Michael Ossmann (actually builds SDR hardware)
“The most impressive live SDR/RF visualizations I’ve ever seen. Implemented by @switchborg in JS w/HTML5 audio source!”
