Christopher (@stoneymonster) and Elecia (@logicalelegance) talks about vacations for learning and hobbies then answered listener questions.

Chris' toys include the Prusa I3 Mk3 and the UAD Arrow.

Elecia likes Camille Fournier's book, The Manager's Path. She also got to plug her own book, Making Embedded Systems: Design Patterns for Great Software.

Brandon Wilson (@brandonlwilson) shared his stories about hacking TI calculators (and other things).

TICalc.org has the latest on getting started yourself including Z80 assemblers, or start on Brandon's website: brandonw.net

Bradon will be speaking at Hardwear.io, a security conference for the hardware and security community. The conference consists of training (11th - 12th Sept 2018) and conference (13th - 14th Sept 2018). It is in The Hague, Netherlands. His talk is The Race to Secure Texas Instruments Graphing Calculators. He will also be hosting a village called Dumping the ROM of the Most Secure Sega Genesis Game Ever Created.

We spoke with Axel Poschmannof DarkMatter LLC(@GuardedbyGenius) about embedded security.

For a great in-depth introduction, Axel suggested Christof Paar's Introduction to Cryptography class, available on YouTube. We also talked about ENISA's Hardware Threat Landscape and Good Practices Guide.

Axel will be speaking at Hardwear.io, a security conference for the hardware and security community. The conference consists of training (11th - 12th Sept 2018) and conference (13th - 14th Sept 2018). It is in The Hague, Netherlands.

DarkMatter is hiring.

Elecia has some discount coupons for the Particle.io Spectra conference.

Derek Fronek spoke with us about FIRST robotics. His TechHOUNDS (@TechHOUNDS868) team is based in Carmel, Indiana. They won the state competition and placed 5th in the high school FRC championship.

Derek mentioned the roboRIO controller board, TalonSRX speed controller, and the Spark motor controller. Many of these offer deep discounts to FIRST robotics participants.

Check out FirstInspires.org to find a team near you. The game comes out in January but many teams start forming in September.

Derek's personal website includes his other projects and a way to contact him.

Sparkfun has an autonomous vehicle competition, this is their 10th year.

Elecia wrote a related blog post for Derek, a few notes about media training.

Gabriel Jacobo (@gabrieljacobo) spoke with us about embedded graphics, contributing to the Linux SDL, using MQTT, and working far from his employers.

Gabriel's blogand resumeare available on his site mdqinc.com. His github repo is under gabomdq.

SDL is Simple DirectMedia Layer (wiki). It is not so simple.

For MQTT-based home automation, he uses the Raspberry Pi Home Assistantbuild and many Node MCUs(ESP8266s running Lua, Micropython, or Arduino Framework).

Micah Elizabeth Scott (@scanlime) came to talk about Fadecandy, a really neat way to control smart LEDs (NeoPixel, AdaFruit's term for the WS2812). The conversation ranged from beautiful LED control algorithms and open source embedded projects to triangle tessellations, art, and identity.

AdaFruit has a great intro to Fadecandy.

Fadecandy is open source hardware and software, see the repository.

Micah's blog is a combo of art and technology.

Burning Man's Ardent Mobile Cloud (also a lovely still pic).

Elecia also mentioned Deep Darc's hack of the GE Color Effects lights.

Jen Costillo (@rebelbotjen) joins Elecia White to discuss the secret parts of C, keywords that only embedded software engineers seem to know about.

Jen and Elecia 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.

NOTE: This is a repeat episode from before we'd settled on our name. Note that Jen is the co-host of the Unnamed Reverse Engineering Podcast.

We spoke with Kathleen Tuite (@kaflurbaleen) about augmented reality, computer vision, games with a purpose, and meetups.

Kathleen's personal site (filled with many interesting projects we didn't talk about) is SuperFireTruck.com.

Kathleen works for GrokStyle, a company that lets you find furniture you like based on what you see. GrokStyle is used in the Augmented Reality try-it-at-home IKEA Place app.
