Embedded

Elecia tries to get a handle on whether Agile works with embedded software.  Curtis Cole (@citizencurtis) argues in favor of user stories, scrums, and story points. Agile software development on Wikipedia Test Driven Development for Embedded C by James Grenning   "Many forms of Government have been tried and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of government except all those other forms that have been tried from time to time." Winston Churchill

Andreas Eieland (@AndreasMCUguy) from Atmel joined Elecia to talk about how the AVR processor line came to life, why there is an AVR in Arduino, and the spirit of making things. Arduino AVR Freaks Atmel’s AVR home OpenCores AVR FPGA implementation Elecia’s new dev kit is a SAM D20 Xplained Pro

Artist Kristin Anderson of Idle Creativity spoke with Elecia about the technology of working with slumped glass, getting started on Etsy (Elecia mentioned her craft electronic ideas), and moving from Silicon Valley technology to artistic pursuits. Kristin's Etsy store, blog, and Facebook page Elecia's intial craft electronics idea and some followup Great book for getting started: Contemporary Fused Glass Kristin suggests Marketing Creativity and  Handmadeology as blogs to help build a craft business Etsy is a great resource for learning to use Etsy: forums and video tutorials.  Bullseye Glass, see classes, especially "Set Your Kiln on Fire" [That does sound fun! -El] Monte Vista embedded Linux Kristin suggests Marketing Creativity and  Handmadeology as blogs to help build a craft business Etsy is a great resource for learning to use Etsy: forums and video tutorials. 

Christopher White ( @stoneymonster) emerges from his producer responsibilities to chat with Elecia about starting a podcast: the gadgetry, the software, the distribution, and, the big question, why we do it. Links from the show:  Libsyn, a dedicated podcast audio hosting service. SquareSpace, fast and easy website building and hosting. 5x5, Dan Benjamin's (@danbenjamin) phenomenal podcast network. Starting a podcast, Dan's guide to podcast equipment. 

Dr. Edward White spoke with Elecia about how technology has changed medicine. He described gadgets used in surgery (harmonic scalpel!), how hospitals acquire tools, and why engineers should be focused on patient benefit.  iPhone based EKG

Karen Lightman (‏@khlightman) joins Elecia White to talk about the infinite awesomeness of tiny MEMS devices. Recorded at the (somewhat noisy but lovely and delicious) Blue Brasserie during SEMICON West. Karen is the Executive Director of the MEMS Industry Group, the nonprofit trade association advancing MEMS across global markets. This the group that wrote the standard definitions that make MEMS easier to use, see the Resources section of their website. MEMS Executive Congress in Napa, Nov 7-8. Please bring new MEMS devices to the pitch event (Elecia is a judge!).  They mentioned some ignorance of RF MEMS, looks like someone need to read this book. Energy harvesting kits we discussed were from MicroGen. They have a neat youtube video. Redux of the Feynman's There's More Room at the Bottom  lecture.

Jen Costillo (@r0b0ts0nf1r3) joins Elecia White to discuss the secret parts of C, keywords that only embedded software engineers seem to know about. They talk about interviewing and why these keywords make good questions for finding folks who use the language to its full potential. On the show they mention a list of embedded interview questions with answers. (Note: Elecia's book has many excellent interview questions and what interviewers look for when they ask them.) Producer Christopher White sends along a more concise introduction to the often unused register keyword. 

Randi Eckstein grilled Elecia White (@logicalelegance) on inertial sensors: when to use accelerometers vs. gyroscopes; gyroscopes vs. rate sensors; how to make an inertial measurement unit; the basics of quaternions and Kalman filters; what products need which sensors (and why). Other good resources: Sensor Wiki (excellent visualizations) Guide to using IMU  (step by step practical information starting with ADC capture) Sparkfun inertial sensor buying guide (descriptions on what's available and how to differentiate between them)

Elecia White is on vacation. Please enjoy some music from the Ballistic Cats!

Josh Chan and Tarun Pondicherry, founders of Light Up, join Elecia White to talk about how to teach electronics to elementary and middle school students. The Light Up Kickstarter ends on June 30, 2013, click on that link to buy your kit or to see the video (including the augmented reality smartphone application). We also talked about going on Kickstarter, being a startup and about HAXLR8R, an accelerator to help hardware startups. El's version of the traffic model of analog electronic components came from There Are No Electrons: Electronics for Earthlings.
