Paul Sidenblad spoke to us about his engineering career, starting off with GE's work on theGambit spy satellite.   Google Protobufs Elecia read Eye in the Sky: The Story of the CORONA Spy Satellites a few years ago and remembers liking it, though this was the first time the information was useful. 

Torie Charvez spoke with us about what it takes to start and run your own business in the US. We talked about starting your own consulting company, selling your latest gadget, and all of the bookkeeping, tax issues, and details involved. Torie's company is Tax Goddess. The write-off publication she mentioned is on the IRS site isChapter 8 of Publication 535. Elecia mentioned her Snow White's Guide to Your First Stock Options.

Craig Smith (@OpenGarages) spoke with us about hacking the software in cars.  His book is the Car Hackers Handbook. There is a 40% off coupon toward the end of the show. OpenGarages is Craig's site to improve and encourage hacking. Some tools he recommends for getting started are USB2CAN and CANTact. An older (shorter) version of the handbook is on OpenGarages. I Am The Cavalry (iamthecavalry.org) is an excellent site for learning more about security.CERT.org is also good. Theia Labs is Craig's company.

Saron Yitbarek (@saronyitbarek) spoke with us about Code Newbie, a site that help people learn to program and about the Code Newbie podcast. We mentioned Paul Ford's Code Newbie episode discussing his Bloomberg issue code. Saron also has a personal blog which has her post I am not a tinkerer. Saron spoke on Punching Your Feelings in the Face at ELA Conf 2015.

Micah Elizabeth Scott (@scanlime) joined us to talk about her new art and engineering projects. Micah's site is misc.name/ and her YouTube channel is micahjd. She launched a Patreon page. Wiggleport has its own site (wiggleport.org) and github (github.com/wiggleport). Check out the art in the repo! The Bela project on kickstarter has some overlap. Micah will be keynoting the 2016 Open Source Hardware Summit in Portland in early October. Her Eclipse project (video) was at the NEAT exhibition at the Contemporary Jewish Museum in San Francisco, CA.  Micah has been on Embedded.fm before: 101: Taking Apart the Toaster (mostly aboutCoastermelt) and 41: Pink Universes Die Really Quickly (mostly about FadeCandy). Micah mentioned Boldport and the kit-of-the-month club. (Video of her building the first one!) Also: the BigClive channel on YouTube. Thank you to Planet.com for sponsoring the contest. Check out Planet.com/careers! 

Philip Freidin (@PhilipFreidin) spoke with us about his BLE platform OSHChip, debuggers, and consulting. Planet Labs is sponsoring a contest! Hit the contact link to enter. Also check out their careers page and apply to embeddedfm@planet.com. Both the OSHChip and the CMSIS-DAP SWD programming module are on Philip's Tindie store. While Keil is the suggested compiler for now,  you can also use mbed (tutorial). The system is wholly open source, you can find everything at github.com/oshchip. (Philip gave anHDDG talk about OSHChip; we didn't talk about it but I thought it was interesting.) Philip's company is Fliptronics. Under Tips and Tricks, that site has his advice on consulting.

Kelly McEvers (@kellymcevers) joins us to talk about the definition of embedded.  Kelly McEvers is one of the hosts of All Things Considered, NPR's award-winning afternoon news magazine. She is also the host of a new podcast called Embedded which takes a story from the news and goes much deeper into it.   Her Embedded podcast launches on March 31st.  Subscribe now on iTunes, listen onNPR.com or your favorite podcast app. Kelly's Diary of a Bad Year: A War Correspondent's Dilemma is an amazing listen. Kelly mentioned her interview of a drone pilot, Lt. Col. T. Mark McCurley, author of Hunter Killer. She also interviewed Sarah Pennypacker, author of Pax. Elecia does not squee on air. But it was a near thing.

Christopher and Elecia chat about the Hackaday prize, Unity class (and their games), the blog, hams, and IDEs. Embedded.fm blog posts we discussed: Chris wrote about ham radio practice tests and his plane's maiden flight. Elecia is working her way through her book about taking apart toys. Chris Svec is taking a microprocessors approach in Embedded Systems 101. And Andrei's current Embedded Wednesdays posts have been about number format and accelerometer output. Sign up for the Embedded.fm newsletter to get blog content in your email box. Hackaday Prize! Yay! Sign up early and often. Chris and Elecia have been taking a Unity course on Udemy (pricing becomes more sensible after April 1). Elecia's game is live for the next 30 days, you can play it from your computer's browser (but not Chrome). Audio "enhances" the experience. Also: you were warned. Atomic Game Engine is another game engine but open source. Justin has 8 reels of 800 of Atmel AT32UC3A3256S-ALVR. Let us know if you'd like to be connected. Elecia liked the Ed Emberley Make A World drawing book. Bipedal robots at RobotShop.com for software programming or SparkFun's Redbot kit for more hardware oriented fun. If you missed last year's April Fools Embedded.fm: The Elon Musk of Earth. Feel free to listen to it again on April 1 as there will be no such gag this year. 

Dan Luu (@danluu) spoke with us about processor features, startups vs large companies, error handling, and computer science research.  Dan's blog is danluu.com. Some posts we talked about: CPU features since 1980 Working at Startups vs. Large Companies Recurring Postmorten Lessons Efficacy of Computer Science Research Areas Dan mentioned some conference proceedings he monitors. For computer architecture: ACM/IEEE International Symposium on Computer Architecture (ISCA):http://isca2016.eecs.umich.edu/ IEEE Computer Society Technical Committee on Microprogramming & Microarchitecture (MICRO): http://www.microarch.org/ High Performance Computer Architecture (HPCA): http://www.hpcaconf.org/ For software engineering: International Conference on Software Engineering (ICSE): http://www.icse-conferences.org/ Foundations of Software Engineering (FSE): http://www.cs.ucdavis.edu/fse2016/ He also mentioned Operating System Design and Implementation OSDI: https://www.usenix.org/conferences/byname/179

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 herRobotic Arts blog. Some other topics we discussed: Sarah got into mechatronics at her time as SAIC. Festo's air jellyfish on youtube Algodoo.com 2d physics simulator Woodgears.ca for 3d printable gears Also, please check out our new embedded.fm/blog or if you prefer email updates, sign up atembedded.fm/subscribe.
