68: Dancing with Hundreds of Women

Angie Chang (@thisgirlangie) joined us to talk about the coding bootcamp Hackbright Academy, their upcoming hardware hackathon, Girl Geek Dinners, and the extreme awkwardness of networking.

Sign up to be a hackathon mentor (not gender limited) or to be on the waitlist to attend (women only). Get your team together on Hackathon IO.

Oh look! Elecia signed up to speak on Sunday!

The article on Peter Thiel and women founders by Kate Losse that Chris referenced toward the end of the show.


67: Software for Things that Can Kill People

In front of a live audience, Chris and Elecia talk about their experiences with FAA and FDA.

This show was recorded live in front of the Silicon Valley Automotive Open Source meetup group at Hacker Dojo

The Wikipedia article on DO-178B is a good place to get an overview of the FAA process (even for other levels of concern).

For FDA, their guidance is the best place to start. Also see their 510k information. Finally, note that all class III (3, very high risk) require the more difficult Premarket Approval (PMA) process.

Everything we know about car safety certification, we learned by reading Wikipedia's ISO-26262, including Automotive Safety Integrity Level (ASIL).

Jack Ganssle's Embedded.fm episode was Being a Grownup Engineer.

66: As Simple as Possible

Jack Gassett (@gadgetfactory) is the creator of the open source FPGA Papilio development board. He joins Chris and Elecia to answer the age-old question of how to get started with FPGAs.

Jack's company is Gadget Factory.

Chris got the Papilio Pro and Arcade MegaWing.

Chris and Elecia will be recording live at Hacker Dojo in Mountain View, CA on Monday, September 8, 2014 at 7 P.M. RSVP!


65: Resonant Frequency of My Butt

Darma (@Darma_inc) is a nascent start-up focusing on optical sensors in a seat cushion to aid in posture, stress reduction, and meditation. Chris and Elecia speak with CEO Dr. Junhao Hu and Sharif Kassatly about building a company, going through the Haxlr8r's accelerator program, and choosing a crowd funding platform.

Keep up with Darma on their webpage and on their Facebook page.

One of their advisors is NASA's Dr. Joan Vernikos, author of Sitting Kills, Moving Heals

64: Making Making Embedded Whoops

WHOOPS! We didn't record Elecia's mic this week and are taking a track direct from Chris' computer mic. Sound quality is not up to our normal standards. Sorry!

Chris (@stoneymonster) hosted the show, asking Elecia (@logicalelegance) what it was like to write her Making Embedded Systems book. (Thanks to Chris Svec for the request!)

63: Dingo-Rabbit Deathmatch

Steve Dalton (@spidie) told us about starting a hackerspace, visiting Silicon Valley with a homebrew incubator group, and tech and fencing Australia. 

Gold Coast Tech Space started off building the Rep Rap 3D printer

Steve's consulting group is Refactor

Silicon Lakes incubator just opened a call for applications to the SURF accelerator

The Arduino-like GCDuino, available on Little Bird

Rabbits are not indigenous and not appreciated in Australia. They have the rabbit proof fence and the Easter Billby

Steve had a podcast Six Degrees and now also listens to STEAM and Engineering Commons.

62: Costs a Penny to Go to the Bathroom

Josh Bleecher Snyder (@offbymany) joined us to talk about PayPal's Beacon, being acquired, the Go programming language, BTLE, computer vision, and working at a large company after founding small ones.

60: Fun Things You Can Make Out of Beagles

Jason Kridner (@Jadon) joined us to talk about the BeagleBone Black... and other things.

Some good books for Beagle :

BotSpeak - A programming language for internet endpoints

To contact Jason about ordering a bunch of units for your OEM use, see his contact info on BeagleBoard.org's About page.

58: Use These Powers for Good

Joe Grand (@JoeGrand) spoke with us about his life as Kingpin, hardware hacking, hosting a TV show, and being a Hackaday judge.

Joe's company is the Grand Idea Studio. His TV show Prototype This was on the Discovery Channel. He created an Atari game: SCSIcide.  Joe will be giving his hardware hacking training at Black Hat USA in August (as well as some of the other security conferences in also Las Vegas at that time).

Joe and Elecia are on the Hackaday Prize judging panel. There are some amazing projects if you want to check out your competition (or vote for the ones you like!).

56: Rodents of Unusual Size

Matt Haines (@beardedinventor) and Tom Byrne (@tlbyrn) spoke to Elecia and Chris about Electric Imp (@electricimp). This discussion goes far beyond our first with Matt (Episode 6!). It is more software and implementation oriented than last week's Amp Hour

In the vein of "what do I do after I've made an LED blink from a webpage?":

Finally, the SparkFun contest winner was announced. There were many great entries, choosing a winner was difficult. Ken M (@Deamiter) won the grand prize. Luckily, Matt and Tom brought two April board + Electric Imp sets to give away so Chris Svec (@christophersvec) and Alex Irvine (@EternalPractice) were runners up. Thank you to all who participated, your ideas were awesome and we loved to hear about them.


54: Oh the Hugh Manatee

Elizabeth Brenner (@eabrenner) returned to the show to talk about the are-you-ok widget that she and Elecia have been working on. (The initial problem-statement show is episode 17.)

There is now a SparkFun tutorial so you can build one of the are-you-ok widgets yourself. As announced in the show, there is a contest to get a SparkFun gift card, it ends 6/13/14 so get your answer in by then (maximum of two entries per person, please).

Elecia already took the name Sal Right out of the running (reference). In the photo below, are Maxwell, Hugh (Cation pattern!), Haley, and Grimes (from left to right) so those are all taken as well.

Noted on the show were two things El saw at the Solid Conference: 3D printed flexible materials from Kinematics and circuit stickers from Chibtronics. Also, we look forward to trying out the Fitbit channel for if-this-then-that (IFTTT) to see if that can monitor our loved ones too.

BONUS: From Solid Con

Elecia attended O'Reilly's Solid Conference, recording a few of the people she met there. Note: this episode is recorded in a noisy location.

Also, thank you to O'Reilly for giving away copies of my book


53: Being a grownup engineer

Jack Ganssle shared his wisdom on being a good embedded software engineer (hint: it takes discipline). 

Jack's website is filled with great essays and new videos. He's also written the Art of Designing Embedded Systems and The Embedded Systems Dictionary (with Michael Barr).

We covered a lot of ground, here are some of the highlights:


51: There is no crying in strcpy

Jen Costillo (@r0b0ts0nf1r3) joins Elecia and Christopher to discuss their experiences interviewing (both as interviewer and interviewee).

Elecia did an hour long webinar on how to conduct technical interviews. In this show, she mentions a good post-interview ratings system.

Google discovered that their brainteasers are not a very effective way to interview.

Despite the news that swearing is good for you, we tried to bleep everything.

Also, it is minesweeper, not minefield. What were we thinking? It was obviously all Christopher’s fault. Though we should have stood up to him. 

Elecia's book has more interview questions but from the perspective of how do you ask a question and what do you look for in a response.
