101: Taking Apart the Toaster

Micah Elizabeth Scott (@scanlime) spoke with us about Coastermelt, art installations, FadeCandy, teaching electronics to artists, and mental health. 

Her Toronto International Film Festival (TIFF) installation is mesmerizing, some videos

In her Coastermelt project, Micah uses the IDA disassembler.

FadeCandy is for sale at Adafruit.

Zen Photon is online, demonstrating ray tracing.

Micah's website shows her current projects. 

Micah's previous Embedded.fm episode focused on FadeCandy: 41: Pink Universes Die Really Quickly.

Robot Odyssey looks awesome.

Captain Awkward is a site where you can get advice on how to say things and deal with difficult situations/people.

Micah's shop has a TypeA 3D printer (note: Tuco's favorite bolts) as well as an OtherMill

100: Unintentional Radiator

Star Simpson (@starsandrobots) and Jen Costillo (@RebelbotJen) catch up with Elecia and Chris, discussing how hobby projects have changed over the last two years since the show started.

99: You Can Say a Boat

Andrei Chichak spoke with us about MISRA-C and ethics. 

Linker post: It's dangerous to go alone! Take MISRA-C

Embedded.fm listener survey (please!)

Andrei's has personal website (we failed to talk about his kite aerial photography, it is really neat though) and his company is CBF Systems.

Plum Hall C Compiler Validation

PC Lint

JPL Coding Standards for C (and the mentioned video discussing Mars Code)

ISO 26262 Automobile software standard

Cortex-R for high reliability systems (ARM's description)

National Society of Professional Engineers code of ethics and Canadian Engineering Guidelines on the Code of Ethics

Offline, Andrei recommended two books and another podcast about MISRA:

 

98: Figments of My Imagination

Chris and Elecia talk about memetics, learning, and processors. 

Elecia was coy about the Pasadena party May 9th and 10th, but Hackaday announced it so you can invite yourself. She will also be speaking at the Solid conference in June in SF (email for a coupon!). She'll also be at ESC-Silicon Valley in July

Star Wars Teaser #2 and SpaceX almost-landing

BLE fun: TI's CC2640 and Nordic nRF51822 (Elecia likes the BLE Nano with the free, online mbed compiler for getting started with the nRF5122).

Everything seems to be a Cortex-M0 these days (including the aforementioned CC2640 and nRF51822). The new Atmel SAM-L series is Cortex-M0 and even more low power than usual. On the other hand, the MSP432 is low power and is a more powerful Cortex-M4 (and inexpensive dev kits!),

Elecia has a book: Making Embedded Systems. It makes a great gift.

 

97: Bubblesort Yourself

Professor Paul Fishwick joined us to talk about CS and STEM education, excellent analogies, and the crossover of art and technology. 

The Linker post related to this episode managed to be reasonably topical for a change.

Paul's work:

 Radiolab Color Episode

Forrester System Dynamics

Max is a visual programming language for music and multimedia.

CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. 

There are many bubblesort dance videos (mindboggling) but this is the one Elecia knew about previously.

The Computer History Museum is awesome. If you are in the area, you should definitely go. 

Conference and contact notes:

96: Yarn Is Very Serious Business

Carrie Sundra (@AlpenglowYarn) spoke with us about doing a Kickstarter on her own… and nearly failing.

The SkeinMinder is an automation tool for small yarn businesses (and enthusiastic amateurs). When the successful Kickstarter nearly fell short, Carrie candidly wrote about it (includes a great description of the economies of scale).

Carrie’s yarn company is Alpenglow Yarn. You can use the contact page there to ask for electrical engineering help as well. Carrie is active on Instagram and her blog is a blend of crafts and engineering.

Ravelry is the social media site for knitters and crocheters (requires free account to see anything)

The insanely popular Potato Salad Kickstarter

 

94: Don't Be Clever

The linker post for this episode is Be Excellent to Each Other.

Dennis Jackson spoke with us about drones (and Airware), simple code, and learning. 

Hobbyist drones and UAVs on Amazon: tiny and cheap,  medium (Christopher's gift), and please-I'm-drooling-right-now. Only the last one may be an Airware platform (Dennis could neither confirm nor deny).

Airware's breakdown of proposed FAA rules

Simple code:

Dennis has also worked on DEKA's iBOT and at Avinger's OCT system.

Dennis had a list of suggested articles and blogs on safety critical software development:

Joel Sherrill (@JoelSherrill) spoke with us about real time operating systems, free and open source software, interns, and space.

RTEMS home page and wiki

Google Summer of Code (the FAQ is the best part!) and ESA Summer of code (awesome tagline: In space no one can hear you code).

The LEON is the ESA Sparc core with open source VHDL and extensive use by ESA.

Some projects RTEMS is used on include the Magnetosphere Multiscale Mission, the ExPRESS Logistics Carrier, Mars Curiosity, and the Dawn spacecraft that is visiting the Ceres asteroid.

92: Everybody Behave, Please

The Linker post for this episode: Make Anything

James @Laen Neal from OSHPark spoke with us about starting a business, helping open source hardware, and throwing wild parties. 

OSHPark got its start from DorkbotPDX.

If you are in Portland, Oregon, check out their meetup (started out on Mondays, now first Tuesday of the month, look at the CymaSpace meetup calendar for the Maker Meetup).

90: Stick It in a Pumpkin

The Linker post for this Episode: Solving a Different Problem 

ThingM's Tod Kurt (@todbot) joined us to talk about the most important part of every embedded system: blinking lights.

ThingM has been making I2C lights (BlinkM, MinM and MaxM) since 2006. 

The newer, more productized USB light is the Blink(1) (there is a coupon near the end of the show). Blink(1) had two successful kickstarters (second one).

The BlinkMs have an ATTiny85 (which is also on the Adafruit Trinket). The Blink(1)s have a PIC processor that is small, cheap, and supports USB quite well (PIC16F1455-I/ML and dev kit).

Other smart LEDs include WS28xx  (aka NeoPixel) and APA102 (aka DotStar)

Seeed Studio was discussed as a way to get boards built, assembled, even housed. Elecia mentioned Tindie's new CM review site.

Tod is cofounder of Crash Space (@CrashSpaceLA), a Los Angeles based hackspace. They (including Tod) were on the short-lived Mythbusters-hosted Rube Goldberg devices show called Unchained Reaction.

Tod has worked on some neat art projects, including the Crystal Monster and the Cash Machine.

Tod's blog.

Speaking of blogs, Chris and Elecia are going to start writing after (podcast) action reports for Element 14. More announcements (and actual links) soon.

Don't forget the Chris Savage (Parallax) call for assistance!
