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).
26: The Tofu Problem
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.
20: Soldered Together By Monkeys
Phil King of Weekend Engineering returned to give Elecia advice on how to fabricate a board, both in a professional capacity and for garage projects. EaglePCB is a commercial package which is also available as a free, noncommercial version for small 2-layer boards. Other open source packages mentioned include Kicad and gEDA. Some board fabricators provide free tools that work only with their fab houses (such asExpressPCB). Digikey's SchemeIt provides a way to get a PDF schematic (and a BOM), but falls down by not providing a way to generate a net list, a critical part of board fabrication. PCB West is this week at the Santa Clara convention center. How Printed Circuit Boards are Designed (1960 Edition) Hildy Licht electronic assembly and manufacturing
19: Bacon and Beer Event
Karen Field (@karenfield) and Elecia talk about 2014 DesignWest, the embedded systems conference, and how to submit your idea for a session. 2014 DesignWest is March 31 - April 3, 2014. Call for abstracts is open, submit your idea! Speaker benefits include speaker room, speaker party, full conference pass, conversation starting badge for networking, plus resume fodder.
18: Brine Solids Building Up in Strange Places
Elecia White and Amy Button discuss Amy's dream of going to Mars, her previous role in training astronauts to handle disasters, and her current work on a magic box of rocks that will keep Orion's air breathable. Mars One Amy’s applicant page (with video) Nixon's moon disaster speech Amy's favorite other applicant
17: Facebook Status: Maybe Not Dead
Elecia White spoke with Elizabeth Brenner about devices that can be used to help families worry less about grandparents who live alone (and 87-year-old neighbor friends named Dolores). Life Alert is the big name in senior push-button call systems. Life Call are the "Help, I've fallen and I can't get up" people. (See the commercial!) Life Call and Lileline have accelerometers to detect falls. Twilio allows programs to send and receive phone calls and text messages using its web service APIs. If This Then That (ifttt.com) connects channels to allow an event to trigger other events (i.e. "failed to twitter today" -> text family) . Fibit API for connecting Fitbit data to other applications. We didn't talk about this but it is a similar idea: Goodnight lamp.
16: Democracy Is the Worst Form of Government
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
15: Robot on the Front
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
14: Hot
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.
13: Introspective Nasal Gazing
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.
12: You Have a Jedi Sword
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
11: Tell Me I'm Wrong, It's Fine
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.
10: Hands Off, Baby
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.
9: Kidnapped and Blindfolded
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)
8: Studebaker Love Story
Elecia White is on vacation. Please enjoy some music from the Ballistic Cats!
7: Lights, Camera, Electrons
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.
