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).
40: Mwahaha Session
Evil Mad Scientist's Lenore Edman (@EMSL) talks about what evil mad scientists do on their path to world domination. Surprisingly, it consists largely of art, education, and soldering. Some EMSL items we talked about: LED Menorah kit (solderless breadboard and soldering version). ATtiny2313 Target Boards Bristlebot: a very cute, easy to build mini robot We also mentioned Maker Faire, a wonderful community, and Dr. Horrible's Sing Along Blog. There is a give away on this show: EMS's Snap-O-Lantern kit. Tweet to Elecia (@logicalelegance) or contact the show. Send in the name of the author of the final quote, first one to do so wins the kit! [Update: Matthew J has won the kit!]
39: I Blame Space
Jen Costillo (@r0b0ts0nf1r3) joined Elecia to talk about Jen's start-up: Bia Sport (@BiaSport). They discuss the difficulties of being in an underfunded start-up as well as the joys of shipping a new product and their upcoming conference talks. Jen discussed the company's focus on safety and privacy at the DesignCon sponsored Geek Girl Dinner. She will be speaking at : Wearables Device Conference. Beyond Activity Trackers: Sport Wearables Thursday, March 6, 2014 3:15pm. (Use the coupon code COSTILLO to save 30%.) EELive's embedded systems conference. Battle Out of Painted Corner, Thursday, April 03, 2014 10:45am. EELive's EE Times Fantastical Theater of Engineering Innovation (in the Expo, free!): Bia Sport Teardown. Time TBD. (With Elecia!) Elecia will also be speaking at EELive, on how the internet of things isn't serving consumers very well on Thursday, April 03, 2014 at 1pm, though the talk title keeps changing.
38: Blame the Monkey
Producer Chris White (@stoneymonster) and Elecia discuss some insurmountable problems and some strategies for approaching them. Google it (or look on Stack Exchange). Explain the problem to someone else… even if they aren't there (use a stuffed animal or write a really detailed email, anticipating potential questions). Draw a picture (system/subsystem architecture or code block diagram or a doodle). Make sure you are running what you think you are, start over from a blank slate, making no assumptions about how your hardware is programmed. Identify and verify your assumptions about the all the pieces involved. Get scientific: define the problem, create a hypothesis, run an experiment, record the results. Small steps! Also: get methodological and write everything down. Return to first principals: how is this supposed to work? Revert to last known good and diff to find the cause of a new issue. Logging functions: they take time but can lead to a better trace, better picture. Make it reproducible: there is information in the solution if you can find the steps to repro. Step by step, reduce the steps until you can nab it in the act. Remove the voodoo. Avoidance: accept the bug (it's a feature!) and go on. Sleep, go for a walk, or work on something else.
37: Surf's Up
Dr. Karen Shell and Elecia talk about modelling vs. building models, ocean albedo vs. ice, climate vs. weather, and science vs. policy. They gloat about being on vacation only intermittently. National Oceanic and Atmospheric Administration (NOAA) NASA's climate change home Help run climate models on your home computer at climateprediction.net Karen's class will be looking at data from NOAA's Climate at a Glance
36: Drive the Boat with a Wii Mote
Elecia gushes about her favorite logic (and protocol) analyzer to Saleae co-founder Mark Garrison. They also discuss start-ups, manufacturing, and covering yourself with rum and pretending to be a pirate when harbor patrol arrives. Saleae Logic 8 on Amazon (or from Saleae) Saleae Logic 16 on Amazon (or from Saleae) Space X reusable rocket video Saleae's blog talks about Mark and Joe's boat, start here The mooshimeter multimeter (as seen on Hackaday and Dragon Innovation)
35: All These Different Reasons Why You Might Want to Do Something
Want to learn how to get from idea to schematic, through layout, all the way to physical boards? Elecia spoke with Chris Gammell about his Contextual Electronics course to teach the missing steps between what an EE learns in college and what an design engineer's job entails. Chris is co-host of the excellent electronics podcast The Amp Hour and author of Chris Gammell's Analog Life. On twitter, contact Chris via @Chris_Gammell or ask questions about the course @ContextualElec. We mentioned UT Austin's online embedded systems course which starts soon as well. Contextual Electronics includes some in-depth KiCad instruction. Some intro (and free) KiCad tutorials: Chris' Getting to Blinky Series teho Labs Wayne and Layne Curious Inventor
34: Really Big Cabbage
Elecia describes to Christopher (@stoneymonster) how to design and create a firmware update mechanism. Hilarity ensues. 4k PC emulator Making Embedded Systems, the book, on O'Reilly (coupon in last 2 minutes of the show) or on Amazon.
33: Quitting My Finnish Lessons
Alison Chaiken (Google+) and Elecia discuss what you need to know to get into development for the automotive market. Check out Alison's she-devel site for a big list of links and resources or go to a Silicon Valley Automotive Open Source Group meetup to say hello. A small subset: Open source engine management system on DIYEFI Car hacking site MP3 Car Vehicle standards ISO-26262 CORRECTION: In the show, Elecia talks about airplane certification levels as though only the size of the plane matters. As listener Burko points out, the certification level also depends on how critical the subsystem is. Those seatback tray tables don't have to be certified to DO178A, but the artificial horizon does.]
32: Woo Woo Woo
Patrick Kane (@PSoC_Nation) is the director of the Cypress University Alliance, working with colleges to provide development kits and information to college (and high school) students. Happily, Patrick brought Elecia a new dev kit: CY8CKIT-042.
31: If You See a Dongle Run Away

In this in-depth technical discussion, Dr. Ken Lunde helps Elecia understand how to internationalize her (memory constrained) device. CJVK Information Processing, Ken’s excellent O’Reilly book on internationalization [Note: there is a 40% off print and 50% off ebook coupon in the last few minutes of the show.] Basic Multilingual Plane (BMP) Images of the bone ideograph that is different between Chinese and Japanese (U+9AA8) can be found on Wikipedia. Other sources of information: Ken’s CJK Type Blog at Adobe Unicode specification, surprisingly readable though large An introductory tutorial Elecia found helpful Open source type faces Source Sans Pro OpenType font family (for UIs) Source Code Pro OpenType font family (for programming environments) Adobe’s open source projects and Ken’s contribution to those: Adobe Blank is a special-purpose OpenType font, making webpages wait to load fonts until they have the correct one AGL and AGLFN (Adobe Glyph List) maps glyph names to Unicode values CMap Resources are used to unidirectionally map character codes CSS Orientation Test are lightweight and special-purpose OpenType fonts that map all Unicode code points to glyphs that indicate their orientation based on the writing direction. Kenten Generic OpenType Font provides glyphs suitable for typesetting emphasis marks in Japanese. Mapping Resources for PDF are used to derive content from PDF files that include CJK (Chinese, Japanese, and Korean) information. You can also reach Ken via lunde "at" adobe.com
25: Thunderdome for Antennas
Jen Costillo surfaced briefly from her startup-induced blackout to share her wisdom about manufacturing consumer products. They discussed new product development and working from (and making modifications to) Hacker Dojo in Mountain View, CA. Jen and Elecia pined for this (probably not really a two pack) microscope.
24: I'm a Total Fraud
Listener Jim Gf posed an interesting question about how to tell if you are a good embedded software engineer. Producer Christopher White joins Elecia to fail to give an answer. While they mention the embedded C test, they devolve into "why would you ask that question?", impostor syndrome, and methods for dealing with it. (Normally our podcasts are recorded during the day but this one was after a long, fairly grueling day for the co-hosts. You may hear the clink of glass as we drank a nice Pinot Noir from Hahn Winery.)
23: Go For Everything I Want
Jeri Ellsworth joins Elecia to talk about about co-founding Technical Illusions and their virtual and augmented reality product CastAR. Jeri gives an in-depth introduction to virtual reality, augmented reality and motion sickness. They also talk about hardware engineers working with software engineers, the CastAR's Kickstarter, children's toys, and tagging sharks for science.
22: Mincraft Is the New Apple II
Jordan Hart from Digital Media Academy joined Elecia to discuss ways to make science, technology, and engineering fun for kids through Minecraft, Arduino robotics, and music. DMA video: Robotics and Electrical Engineering with Arduino TED talk: The child-driven education which describes the "method of the grandmother" teaching style. Georgia Tech online CS Master's degree Sincere apologies to fans of Gottfried Leibnitz, he had a truly amazing career that went well beyond calculus, read about it on Wikipedia.
21: The Tent Is Flat and Everyone Is Wet
Rob Mitchell and Elecia discuss management, what they like about project schedules, and lessons learned on the path from engineer to manager.
