Embedded

Christopher White resurrects an Apple ][+ with his brother Matthew White. This is a show about the software Christopher and Matthew wrote when they were kids and the hardware they wrote it on. Matthew's favorite fictional robot (we should have asked): Venus Probe from Six Million Dollar Man. We did ask about his favorite fictional computer and there is a video for that too. Apple ][+ Wiki Timex Sinclair Z81 Wiki  Eric Schlaepfer's Monster 6502 Grant's 6502 Computer Kerbal Space Program for the Apple ][ Elecia got to $42 in Lemonade Stand by the end of the show Matthew's Nebula Wars and Eye of Eternal Death BASIC games circa 1985 and 1981 respectively. If you feel like it, you can try out an Apple ][ in your web browser, with tons of disks available at the Internet Archive or in a Javascript Emulator. Elecia's book is Making Embedded Systems.

Elecia went to Hackaday's SuperCon, got to announce the Hackaday Prize 2015 winners, then talked to the organizers about their conference. The guests this week were (in order of appearance): Amber Cunningham Dan Hienzsch (115: Datasheeps) Adam Fabio Brian Benchoff Aleksandar Bradic Sophi Kravitz (77: Goldfish, Fetch My Slippers! and 91: Save Us from Astronauts) Mike Szczys (69: Look at this Entire Aisle of Standoffs) Tamagotchi Hive Adam promised us a list of contributors to the goodie bag.

Nadya Peek (@nadyapeek) joined us to talk about making machines that build things.  Nadya's website is infosyncratic.nl, which includes her blog. Nadya's dissertation defense on Making Machines that Make: Object-Oriented Hardware Meets Object-Oriented Software was standing room only. MIT Center For Bits and Atoms, which studies "how to turn data into things, and things into data." Mods.cba.mit.edu Machines that Make: MTM.cba.mit.edu

Valve's Alan Yates (@vk2zay) spoke with us about the science and technology of virtual reality.  Elecia looked at the iFixIt Teardown of the HTC Vive system as she was unwilling to take apart Christopher's system.  Alan shared some of his other favorite reverse engineering efforts: Doc OK’s Lighthouse videos, documentation on github by nairol, and a blog by Trammell Hudson. Alan's sensor circuit diagrams were on twitter: SparkleTree sensor circuit (think simplified) and the closer-to-production Lighthouse sensor. Make Magazine talked about Valve's R&D Lab. This is important in case you want to work at Valve (they are currently hiring for EE but if that doesn't describe you and you want to work there, apply anyway). Alan also has a website (vk2zay.net) though it doesn't see much updating right now.  

Kat Scott (@kscottz) gave us an introduction to computer vision. She co-authored the O'Reilly Python book Practical Computer Vision with SimpleCV: The Simple Way to Make Technology See. The book's website is SimpleCV.org. Kat also suggested looking at the samples in the OpenCV Github repo.  To integrate computer vision into a robot or manufacturing system, Kat mentioned ROS (Robot Operating System, ROS.org). Buzzfeed had an article about SnapChat Filters. Kat works at Planet. And they are still hiring. 

Daniel Hienzsch (@rheingoldheavy) and Majenta Strongheart (majentastronghe_art) gave us suggestions on setting up a home shop and information on setting up a maker space. Daniel is the resident engineer at SupplyFrame's Pasadena Design Lab. He still the owns and runs RheingoldHeavy.com, a company devoted to educational boards, as we talked about on episode 115: Datasheeps. Majenta's web page is MajentaStrongheart.com. We talked more about School of the Art Institute of Chicago with Sarah Petkus in 142: New and Improved Appendages.

Chris and Elecia talk to each other about compiler optimizations, bit banging I2C, listener emails, and small-town parades. Games to learn/play with assembly languages include The Human Resource Machine by Tomorrow Corporation and TIS-100 by Zachtronics. We've been enjoying the Embedded Thoughts blog. And Chris is reading Practical Electronics for Inventors and liking it.  We talked a little about Interview.io's adventure in voice changing. Shirts are gone for awhile. New logo stickers are available at StickerMule if you'd like to support and share the show. 

Fabien Chouteau (@DesChips) of AdaCore (@AdaCoreCompany) spoke with us about theMake with Ada Programming Competition. Giveaway boards are GONE.  The Ada programming language (wiki) is interesting in that it was designed for safety critical embedded systems (actually designed, requirements doc and everything!). The Ada Information Clearinghouse has a nice list of tutorials and books as does the very helpful Make with Ada Getting Started page. Elecia's favorite was Inspirel's Ada on Cortex. Some neat projects in Ada that we mentioned on the show: Fabien's CNC Controller (with code in github) Tetris on a Smart Watch (with a formal proof via SPARK) Nano drone flight controller (with formal proof via SPARK) The platforms supported in the contest are on the Getting Started page but you can expand that by looking at the SVD files in the AdaCore drivers on github. (Also, SVD files are neat.) One of the platforms already supported is the Crazyflie nanodrone. 

Robb Walters of Flybrix (@flybrix) spoke with us about LEGO-based drones. We graciously let him leave with all his hardware. This time. For a limited time, you can get an Embedded.fm tshirt: teespring.com/embedded-fm. Order by the end of June or miss out. (More info about the shirts.) You can order your Flybrix kit and or read their controller code on github (or their controller app code). Robb mentioned a C++ book he liked, it was Effective Modern C++: 42 Specific Ways to Improve Your Use of C++11 and C++14 by Scott Meyers. He also noted LEGO bricks resale sites: Brickowl and Bricklink. LEGO Digital Designer looks like a fun way to design builds. Cascade PID controllers are on Wikipedia (though I found this tutorial a little easier).  The congratulations offered at the top of the show were to Meshpoint.me for winning the Best Humanitarian Tech of the Year at the Europas Conference.

Jeri Ellsworth (@jeriellsworth) spoke with us about the latest developments at CastAR, hiring engineers, and her favorite engine. Embedded.fm T-Shirts are available until the end of June on Teespring (more info). CastAR is making an augmented reality system. They are in Palo Alto, CA, USA and they arehiring.  They work with Playground. Jeri was last on Embedded.fm episode 23: Go For Everything I Want.
