Better Snowmen in Finland
Becky Worledge of the Qt Company (@qtproject) spoke with us about application frameworks, organizing large code bases, and automotive regulations.
The best place to get started with Qt is the getting started page: doc.qt.io/qt-5/gettingstarted.html
Or skip that and head straight for the code: github.com/qt
Maybe backtrack to see what is available: qt.io/product/features
Hmm, was there talk of Qt and Python? PySide was it? qt.io/qt-for-python
But wait, Qt for MCU? What platforms are supported? QtForMCUs/qtul-supported-platforms.html
Finally, don’t get eaten by a Grue, sense when they are coming: doc.qt.io/qt-5/qtsensors-grue-example.html
Qt6 is coming out Dec 2020. So maybe replace all the qt-5 in the links with qt-6 to see if it is ready yet!
Oh, and Qt is hiring: qt.io/careers
The quote at the end is not from Abraham Lincoln. (Quote Investigator). Still a good thought.
Red for the Ones That Might Blow Up
Seth Hillbrand (@SethHillbrand), lead developer for KiCAD (@kicad_pcb), spoke with us about open source development, EDA tools, pronunciation, and inclusion.
Check out KiCAD!
Seth’s company provides support for KiCAD (kipro-pcb.com, @kiproeda).
Baby's First Hydrofluoric Acid
John McMaster (@johndmcmaster) told us about the process of opening up chips to see how the processors are structured and what the firmware says.
See John’s website for information on getting started (as well as digging much deeper).
John has given some interesting Hardwear.io talks including Capturing Mask ROMs and Taming Hydrofluoric Acid to Extract Firmware. His talks and many others are available on the Hardwear.io archive. Or sign up for the Hardwear.io Online Hardware Security Training, Berlin Jan 2021.
As mentioned in the show:
John wrote a blog post about his top lab accidents and explosions.
Paper: Reverse engineering Flash EEPROM memories using Scanning Electron Microscopy by Franck Courbon, Sergei Skorobogatov, and Christopher Woods
Rompar and bitract are the two programs mentioned as helpful for getting from an image to binary code.
Dextral or Sinistral
Chris and Elecia discuss transcripts, lightsabers, seashells, python, numpy, matlab and how to get into embedded systems development.
Embedded show transcripts are available at embedded.fm/transcripts
Elecia’s origami github repository includes a python script for generating origami shell folding patterns. The paper described was Analysis of Shell Coiling: General Problems by David M. Raup from the Journal of Paleontology , Sep., 1966, Vol. 40, No. 5.
Chris used this model to print his lightsaber: Star Wars Lightsaber (Normal version) from YouMagine

The State of the Empire Is Good
Ben Hencke (@ledmage, @im889) updated us on blinking lights and running a small hardware business. You can find the current PixelBlaze in the Electomage store on Tindie (tindie.com/stores/electromage/) or signup for a shiny new version on CrowdSupply.
Ben’s personal site (bhencke.com) has lots of projects including a page devoted to the awesome Pixelblaze projects (including the BioTronEsis alien light sea creatures which someone who hosts this show hopes will be in her Christmas stocking).
When Ben is making Pixelblaze, the brand is ElectroMage (electromage.com/) so you can see more about Pixelblaze there including the forum.
We didn’t talk about TapGlo, the arcade ping pong table that Ben is also working on.
Favorite solder paste: LOCTITE GC 10 paste (henkel-adhesives)
About his favorite acronym, Ben says, “XMLHttpRequest is my favorite because it perfectly illustrates how we're (developers) bad at naming things and like to come up with arbitrary rules for things. The story about how XML is all caps and Html is camel case is just too perfect, and it's popular use rarely has anything to do with XML”
Finally, There are 40 different flavors of Kit Kat. There are 12 flavors of candy corn, they all taste the same.
The Cilantro of Robots (Repeat)
Christine Sunu (@christinesunu) spoke with us about the feelings we get from robots.
For more information about emotive design, check out Christine’s website: christinesunu.com. From there you can find hackpretty.com, some of her talks (including the TED talk with the Fur Worm), and links to her projects (such as Starfish Cat and a Cartoon Guide to the Internet of Things). You can find more of her writing and videos on BuzzFeed and The Verge. You can also hire her product development company Flash Bang.
Embedded 142: New and Improved Appendages is where Sarah Petkus offers to let her robot lick us.

Books we talked about:
Accelerando by Charles Stross
Alone Together: Why We Expect More from Technology and Less by Sherry Turkle (MIT site)
Reclaiming Conversation: The Power of Talk in a Digital Age by Sherry Turkle (MIT site)
Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness by Peter Godfrey-Smith (Note: Elecia also wrote a whole octopus annotated bibliography in a recent post)

Great Geek Podcast
This podcast is great, if you’re a geek like me.
For all embedded enthusiasts out there
I really enjoy the discussions about embedded systems. Elecia and Chris are super engaging and entertaining.
Yay! An embedded podcast!
I’ve listened to other technical podcasts, but this one has really kept my interest. Elicia and Chris do a great job of discussing both software and hardware, and they do it in a really fun way. Its also technical enough that I’m always wanting to go to the show notes to get more details on the projects they discussed or that new micro I never heard of.
They interview some awesome people as well who seem to do some amazing things.
Thanks for the great podcast you two. It makes my commute to work and dishwashing after dinner more enjoyable. :)
