I am Elecia White alongside Christopher White. We’re here to chat about the interests, careers, and lives of engineers, artists, educators and makers. Our diverse guest list includes names you may have heard and engineers working quietly in the trenches. Either way, they are knowledgeable, enthusiastic, and inspiring.
We’d love to share our enthusiasm for science, technology, engineering, art, and math (STEAM).
127: Chicken Equals Duck Plus One
🐔=🦃+1 (or Why isn't there a duck emoji?) Christopher and Elecia talk about languages, twitter, listener emails, and Star Wars. Podcast Awards The Amp Hour talked about languages, they also referenced this compiler writing exercise C alternative tokens iso646.h and an up to date C reference (Harbison and Steele) $20 Linux board from vocore.io Real Strawberry DNA extraction technique (Elecia forgot the soap and the salt.) fromScientific American (with real science) or in easy-to-follow picture form on genome.gov.
125: I Like Cheat Codes
Dan Shapiro (@danshapiro), CEO of Glowforge (@glowforge), speaks with us about laser cutters and his book, The Hot Seat. If you succumb to the wonder of 3D laser printers, consider using our Glowforge link so you get $100 (and we get $100). Dan's book, the one Elecia gushes about, is The Hot Seat: The Startup CEO Guidebook. Some of that information is also found in Dan's blog. If you are in the Seattle area, Glowforge is hiring! Check out their jobs page. We didn't talk much about Robot Turtles, a game to teach programming principles to preschoolers.(Also on Amazon.) There is another interesting interview with Dan at Tested.com.
124: Please Don't Light Yourself On Fire
Windell Oskay (@Oskay) of Evil Mad Scientist Laboratories (@EMSL) told us about co-authoring a book: The Annotated Build-It-Yourself Science Laboratory. Some great EMSL links: A signed copy of Windell's book Dis-integrated 555 timer kit Candle flicker LEDs Food in specimen jars EMSL blog post Spherical pen plotter (EggBot Pro!) The book Chris brought up was Thinking Physics. Windell is also on Google Plus. Contest to get Windell's signed book ends 11/13, send in your entry!
123: Banished from Running Linux
Bob Coggeshall (@BobCoggeshall) runs a boutique assembly house. And he co-wrote sudo. There are sandwich jokes. Bob's business is Small Batch Assembly (@SmallBatchA). (There might be a discount on your first order near the end of the show. Maybe.) His pick and place machine is a Mancorp MC400. Octopart's Common Parts Library We mentioned OSHPark a few times, Laen has been on Embedded.fm: 92: Everybody Behave, Please Boldport makes nonlinear traces (SEAHORSE!!) Relevant XKCD panel My Date with Drew How did we not know about Astromech.net? Bob's Wifi Nixie driver board (also: how Nixie tubes work)
122: Glue a Board to Your Resume
Chris and Elecia try out their new recording location, give advice for getting a job in embedded software, and respond to listener emails. SparkFun's Pit of Despair is a blog post about how to create products from prototypes. Visual Studio has plug-ins that support microprocessors, see Visual Micro. The Guardian reports that 2016 VW models have a different defeat.
121: The Idea of Mojo
We spoke with Fran Blanche (@contourcorsets) of Frantone about guitar tone. Fran has several articles and posts about space, electronics, and assorted whatnot at her design writings page. Her video blog is on YouTube. There are many different guitar pedals you can build for yourself as a way to get a better handle on analog electronics. Elecia found these at Mammoth Electronics. The song that was the first to have flanging was "The Big Hurt" by Toni Fisher in 1959.
120: Boll Weevil Eradication
Kathleen Sidenblad discusses her career through Silicon Valley, from engineer at Systems Control Inc in 1976 to VP of Engineering today. For more about Kathy, check out this Storehouse interview.
119: Do Your Neighbors Have Any Idea?
Ben Krasnow of the Applied Science YouTube channel talks with us about scanning electron microscopes, generating liquid nitrogen, and cookies. Hackaday Conference is Nov 14-15, 2015 in SF, CA! Call for proposals. (Ben and Elecia are Hackaday Prize Judges.) Contact Ben through twitter: @BenKrasnow Applied Science YouTube channel (and don't forget the associated Patreon). Some specific videos we talked about: Cookie machine Electron microscope scanning vinyl record Faraday effect (control light with magnets!) LED contact lens (not for the squeamish) Other people's videos and projects: Brady Haran's Periodic Videos Veritassium channel Build your own waterjet Amscope microscope and low cost hot air rework soldering station
118: Awesome and Frequently Useless
Morgan Allen (@captain_morgan) spoke with us about Sphero and Node.JS. This is all not-so-secretly a discussion of the BB8 robot. Correction: Despite Elecia's repeated insistence that these are steppers, she's just wrong. The motors are DC which only makes sense in a consumer product. More details on this in a later episode. BB8s from Amazon (probably won't arrive until next year) More info on Elecia's teardown and talk: embedded.fm/hddg The BB8 toy is based on Sphero (buy). They have an open SDK and a wonderful education program. Check out the clear SPRK (buy). It also has a teach-your-kids-to-program app that is pretty neat (but doesn't seem to work with BB8 yet). Morgan has been involved with NodeBots (@nodebotsSF). They use Node.js (wiki) to send Bluetooth serial commands to Spheros. Their issues list is where new meetups are posted. Johnny-Five is also a popular way to do computer based robotics with an Arduino (or other dev board) as a hardware intermediary. IPFS: Distributed file system ESPruino is a Javascript board. People's Open: Free Wireless Internet and Local Network in Oakland, California. Also in Oakland, check out Sudo Room hackerspace.
117: In as Much as Which
Chris and Elecia discuss listener emails and other assorted topics. Preprocessor fun BLE 4.2 writeup from EETimes and the FAQ from Bluetooth.org Drones should follow existing aviation keep out standards (Nick links us to some wiki pages) Automatic dependent surveillance NOTAM Federal Aviation Regulations: Temporary flight restrictions NYT Amazon culture article Cake under a microscope
116: You Have to Care
Glenn Scott (@GlennCScott) spoke with us about API design and techniques for writing good software. Glenn glossed over his bio but it is quite impressive. You can reach him via his PARC page. PARC's Content Centric Networking home: ccnx.org which we talked about in 75: End Up in a Puppy Fight. Literate Programming by Knuth And the more recommended Bob Martin's books While latest source code requires licensing, the binary version of CCN includes the LongBow tools (in user/local/parc/bin). Description of tools and doxygen docs. The LongBow getting started guide should be part of the mid-September binary release. PARC's C Style Guide and C Function Naming Guide
115: Datasheeps
Daniel Hienzsch (@rheingoldheavy) spoke with us about reverse engineering a board, bypass capacitors, and serial protocols. Rheingold Heavy is Dan's company for educational boards. The one he started with was the I2C and SPI education board (its fulfilled kickstarter page). He brought us the theGraphic Equalizer Kit and Bubble Display Experimentation Pack. Dan's Arduino from Scratch blog series looks at the Arduino hardware in great detail. Contextual Electronics course for learning to build boards Chris wrote about his Photon based garage door opener on the Linker blog TinEye for searching schematic snippets
114: Wild While Loops
Andrei Chichak rejoins us to discuss error handling. Andrei's website says how to reach him or email embedded 'at' chichak.ca Windows 10 "Something Happened" error Hitchbot Book Elecia mentioned: Kindness of Strangers by Mike McIntyre Elecia's book covers logging module in Creating a System Architecture (pp 21-25) Robots and children
113: A Noddy Little Program
Clive Turvey (Clive1), master of the ST Forums, talks with us about ARM cores and answering difficult technical questions for fun. Some answers: NVIC Interrupts on the same pin number STM32F4 PWM channel 3 ST's Cortex-M7 Books (though we talked more about these being good authors, these are the ones Chris and Elecia have or want): The Definitive Guide to ARM Cortex-M3 and Cortex-M4 Processors, 3rd Edition (Joseph Yiu, 2013) The Definitive Guide to ARM Cortex-M0 and Cortex-M0+ Processors, 2nd Edition (Joseph Yiu, 2015) Z80 Assembly Language Programming Paperback (Lance A Leventhal, 1979) Programming the 6502 (Rodnay Zaks, 1979) A bare metal Scheme interpreter for ARM.
112: My Brain Is My Resource

Natalie's site and blog Hardware Excuse Generator Original CCC 2012 talk: Many Tamagotchis Were Harmed in the Making of this Presentation CCC 2013 talk: Even More Tamagotchis Were Harmed in the Making of this Presentation Natalie's upcoming BlackHat talk: Attacking ECMAScript Engines with Redefinition Flash exploit article for Project Zero: One Perfect Bug: Exploiting Type Confusion in Flash Tamagotchis are still available as are the works of Shel Silverstein (Snowball is in Falling Up).
110: Happiness Is a Warm Puppy
BeagleBone's Jason Kridner (@Jadon) returns to tell us about his new book. Jason co-authored a new book: BeagleBone Cookbook: Software and Hardware Problems and Solutions (or at O'Reilly). His older book is Bad to the Bone: Crafting Electronics Systems with Beaglebone and BeagleBone Black. Previous Embedded.fm episode 60: Fun Things You Can Make out of Beagles BeagleBoard.org's Google Summer of Code page (including BeagleSat and underwater drones!) Some information about putting Xenomai on a BeagleBone Black for real time response. Chris mentioned Brillo, an alternative Google supported OS that isn't on the BBB. Project Ara: an open source smartphone Ardupilot: Autonomous drone piloting. Dronecode: Drones in Linux OpenROV: Underwater vehicles Mars lander Beagle 2 (the Apollo 11 Lunar Module was the Eagle despite some comical confusion). [UPDATE: Listener Mark Stevens pointed out that the Apollo 10 Lunar Module was named Snoopy who was a beagle.] TI's E2E Forums BeagleBone Green
109: Resurrection of Extreme Programming
James Grenning (@jwgrenning) returns to discuss TDD, Agile, and web courses. James was on Embedded.fm episode 30: Eventually Lighting Strikes. James' new company is Wingman Software. His excellent book is TDD for Embedded C. James suggested Training From the Back of the Room! as resource to people looking to put together a class. He uses and recommends CyberDojo as a coding instruction tool. Before Agile was Agile-for-business, it was Extreme Programming. James recommends Extreme Programming Explained. James will be the keynote speaker at AgileDC in October.
108: Nebarious
Jen (@RebelbotJen) joined Chris and Elecia to discuss security, privacy, and ethics in wearable computing. Elecia's Linker post is especially relevant this week: Device Security Checklist.. There is already a standard for privacy and security: HIPAA (Title II). While not easy to read, it is a reasonable starting place. Another good (but not quite on-point) resource is the EFF Secure Messaging Scorecard, especially if you consider your device as messaging your user (it's a metaphor, ok?). Also, read all the way to the methodology, not just the pretty checkboxes. Mike Ryan has great explanations for how to easily crack BLE security. Video to watch. His website has more resources, papers, videos, tools. The Embedded Systems Conference (Silicon Valley) will be held at the Santa Clara convention center July 20-22. Wearables and IoT Growing Up: Talking To Your Products About Security And Ethics(Jen, Wed 11am) Teardown: Wearing Security on Your Sleeve (mostly Jen with Elecia telling jokes if/when things go wrong, Tue 1:30pm, on the show floor so free to attend with an Expo pass. We'll be taking apart a Nymi band.) Faker to Maker in 45 Minutes or Less (Elecia, Wed 1:30pm) Casino article: Breaking the House Chris and Elecia were guests on The Amp Hour. Jen is interested in putting together a workshop/conference on the intersection of art, dance, and technology. Contact her on Twitter or email info at rebelbots dot com.
107: Until They Are Spaghetti
We talked to Craig Cook about learning embedded systems. He recently attended an embedded edX course through University of Texas. The microcontroller and boards used in the course Craig's next course will be Interactive Python through Coursera As we discussed Craig's alarm clock we mentioned many parts including: FM Module ESP8266 WiFi Module Electric Imp (Sparkfun or Digikey, don't forget the April breakout board) Chris has also been looking at Particle.io's Photon board for WiFi + cloud development. This will be mentioned on other shows (as well as on The Amp Hour).
