Sincere apologies to fans of Gottfried Leibnitz, he had a truly amazing career that went well beyond calculus, read about it on Wikipedia.
Rob Mitchell and Elecia discuss management, what they like about project schedules, and lessons learned on the path from engineer to manager.
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 as ExpressPCB). 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.

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.
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.
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.

"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.
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.

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.

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.
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:

Akkana Peck (@akkakk) joins Elecia White to talk about an introduction to Arduino workshop for high school students.
Arduino boards are a fantastic way to encourage people into embedded systems. The boards are cheap, the starter kits are great, there are lots of things you can do with them, and the compiler software is free.
Akkana's site (Shallow Sky) has the workshop outline, going from morning general activities to afternoon specific ones. The really simple circuit for the photo-theremin we had on the show is linked from there (and the latest code is on github). A separate post describes the the cheap motor boards she's been working on, including the specific chips (including the H-bridge).
The summer camp we discussed is GetSET and they eloquently describe themselves as "a program for high school girls of underrepresented ethnic groups to show them that engineering is fun, is creative, improves lives, and is an exciting career option". It is free to the student, funded through the efforts of the Santa Clara Society of Women Engineers (SWE) chapter.
To volunteer for Akkana's workshop (Wednesday June 26, 9am-4pm at Santa Clara University) contact her on twitter or email us here at the show (show@makingembeddedsysetms.com).
Elecia and Chris (@stoneymonster) discuss why they chose to go into consulting and what they've learned while building Logical Elegance into the company it is.
