Embedded is the show for people who love gadgets. Making them, breaking them, and everything in between. Weekly interviews with engineers, educators, and enthusiasts. Find the show, blog, and more at embedded.fm.
You Can Never Have Too Many Socks
Thea Flowers (Stargirl, @theavalkyrie) creates open source and open hardware craft synthesizers that use Circuit Python for customization. She also writes about the internals of the SAMD21.
Thea’s synthesizer modules are found at Winterbloom, including Castor & Pollux and the Big Honking Button. It is all open source hardware so you can find code and schematics on Thea’s github site: github.com/theacodes
Thea’s site is thea.codes. You can find her blog there with deeply technical and detailed posts such as The most thoroughly commented linker script (probably), The Design of the Roland Juno oscillators, and Understanding the SAMD21 Clocks.
For more information about the Eurorack, listen to Embedded 356: Deceive and Manipulate You with Leonardo Laguna Ruiz of Vult.
Emily Velasco (@MLE_Online) spoke with us about artistic projects, retro-future aesthetics, and scientific communication.
She shows and describes the projects on YouTube: Emily’s Electric Oddities including the Optical Sound Decoder, Port-A-Vid, Hairy Cacti, and the Lissajukebox.
Many of Emily’s professional writings can be found on Wevolver, usually redirected to sites where they are published.
How Do You Think Waffles Work?
Chris and Elecia talk about making albums, making progress, DIY shot reporting, getting credit, and project management.
Check out the Embedded transcripts (now with older shows appearing weekly!). The Embedded Patreon provides the funds for guest mics, transcripts (new and old), and new shirt designs. Thank you very much to the supporters.
Thank you to our listeners for raising over $5000 for DigitalNest!

Thank you to 2020 sponsors including Qt and Triplebyte as well as InterWorking Labs for their early patreon-business-level support.
We’ll Pay Them in Fun (Repeat)
We spoke with Kathleen Tuite (@kaflurbaleen) about augmented reality, computer vision, games with a purpose, and meetups.
Kathleen’s personal site (filled with many interesting projects we didn’t talk about) is SuperFireTruck.com. Her graduate work was in using photogrammetry to build models.
Kathleen works for GrokStyle, a company that lets you find furniture you like based on what you see. GrokStyle is used in the Augmented Reality try-it-at-home IKEA Place app.

Deceive and Manipulate You
Leonardo Laguna Ruiz of Vult spoke with us about modelling electronics, modular synthesizers, and modulating sound. We talked in detail about applied digital signal processing.
Leonardo’s website is www.vult-dsp.com. Check out the Freak Filter, the user manual alone is a course in signal processing. You can buy finished or DIY versions on vult-dsp.com/store.
The physical hardware is a Eurorack module (wiki) but the Vult modules are also available for the VCV Rack, a Eurorack simulator that you can use to build your own modular synthesizer.
Leonardo has a YouTube channel where he goes in depth on signal processing: youtube.com/c/LeonardoLagunaRuiz. He’s also written about modeling vintage analog sound on the Wolfram blog.
For more information about the Vult programming language (or an example for how to build your own, check out the github repository: http://modlfo.github.io/vult/overview/
This episode was sponsored by Qt, a cross platform application framework for desktop, mobile and embedded devices. That means you get a full set of libraries for nearly everything you can think of, plus a world-class GUI that will give you a native look wherever your code runs.
Try Qt for free at www.qt.io/download (qt.io/embeddedfm ! And check out Qt for MCUs!)
Favorite Ways to Make Noises
Helen Leigh (@helenleigh) joined us to talk about music, electronics, books, and starting a new job at CrowdSupply (@crowd_supply).
Helen was previously on Embedded #261: Blowing Their Fragile Little Minds where we talked about subversive geography, her book The Crafty Kid's Guide to DIY Electronics, and the mini.mu musical gloves.
Helen has a book coming out in 2021 about DIY Music Tech including a soft version of the Michel Waisvisz' CrackleBox (Kraakdos). Check out some of the projects in HackSpace magazine issue 36 and 37 (the book will be serialised in HackSpace). Or look on YouTube for some examples of Helen’s purring tentacle and her circuit sculpture harp.
Helen mentioned Bunnie Huang’s Precursor, an open mobile phone, on CrowdSupply (campaign ending shortly).
The Giant German Congress mentioned is the CCC Congress Festival
Helen’s preferred thread (the one you can actually get) is Madiera’s conductive threads. Hit the contact link for purchasing. (Helen notes you can use it for both sides in a sewing machine!)
