Embedded

Sarah Petkus offers to let her robot lick Christopher's leg. Christopher agrees reluctantly once we determine the saliva will be anti-bacterial hand sanitizer. Sarah is a kinetic artist and some of her projects include a robot army (built your own from parts printed out or purchased at robot-army.com), Noodlefeet, and Carl (the flamingo of pendulum inversion). Her Zoness.com site is an umbrella for her drawn and robotic art. Specifically, you may enjoy her webcomic Gravity Roads, her YouTube channel, and/or her Robotic Arts blog. Some other topics we discussed: Sarah got into mechatronics at her time as SAIC.

Andrei Chichak and Chris Svec join us to talk about our new blog: Embedded.fm/blog (!!). Andrei was on 114: Wild While Loops, about error handling, as well 99: You Can Say A Boat, about MISRA-C. Andrei has been teaching Embedded Wednesdays, an embedded systems class for the Edmonton New Technology Society. It uses the STM32F401C-Discovery board. His course materials are on his site (chichak.ca). Chris was on 78: Happy Cows, about empathy driven development. He's also working on a different embedded systems introduction (Embedded Software Engineering 101). His blog is chrissvec.com. Our new blog will include their coursework, excepts from Elecia's new book on taking apart toys, project notes from Christopher, and various other news.

Chris (@stoneymonster) and Elecia (@logicalelegance) answer listener questions about BASIC and their meet-cute story. (Sadly those are unrelated. That would have been cute.) Dennis Jackson at Airware is looking for a senior EE and an EE technician. Contact us and we'll connect you to Dennis so he knows to look out for you. Dennis' episode was 94: Don't Be Clever about drones, simple code, and learning. As for other interviews, Elecia was on The Amp Hour and The Engineering Commons Podcast. Elecia and Chris were both on The Amp Hour's 256th show.

Dan Saks answers many questions about C++ in embedded systems: where it works, where it doesn't, and a path to getting started. Dan Saks is the founder and president of Saks & Associates. He was a columnist for The C/C++ Users Journal, Embedded Systems Design and several other publications. He also served as secretary of the ANSI and ISO C++ standards committee in its early years. We touched on some of his articles: Poor reasons for rejecting C++ Preventing dynamic allocation Calling constructors with placement new Andrei suggested Sams Teach Yourself C++ in One Hour a Day, Seventh Edition by Siddhartha Rao as a good primer for experienced C programmers reluctantly learning C++.

Inventor and Youtube-er, Simone Giertz (@SimoneGiertz) tells us about building robots to "help" her daily life. Simone's YouTube Channel. Some of the videos discussed in the show: Chopping Machine VLOG and its TV commercial (Also: the servo motors used) Listener Feedback with TENS machine Wake up machine Simone's blog, with additional robot build details is at simonegiertz.com. For relaxation, Simone visits the Hello Denizen YouTube channel and watches hamsters eating gourmet meals. She also mentioned her preferred Reddit feed. Like robots?
