455: Snaps!

Uri Shaked surprises us with a chat about silicon design when we were expecting to talk about a web-based board simulator.  If you want to try your hand at silicon design, check out Tiny Tapeout, a way to possibly get your design on to real silicon. The digital design guide is a great way to start looking at how chips work. If you aren’t quite ready for silicon, Wokwi has a Verilog simulator where you can learn to do the digital design. The Verilog Simon Game on Wokwi is amazing.  Wokwi is a web-Based simulator, simulating processors, boards, and peripherals. You can build a whole system there, from Dancing Servos to 7-Segment display from 30  LCDs and Arduino Mega to Raspberry Pi Pico boards you can program in C when you click More Options on the front page. You can also create your own peripheral using the Chip API. Or learn to use  Zephyr on Wokwi. And now there is Wokwi for VS Code.  All that and Wokwi is open source: github.com/urish Uri recommends reading Relax for the same result by Derek Sivers Previously on Embedded 396: Untangle the Mess Transcript

454: Printf Hello

Nathan Jones has been talking about building command line interfaces, good design practices in C, creating MCU boards, wielding the PIC of destiny, and going beyond Arduino. As we are too lazy to attend the conferences, we asked him to give us the highlights.  Nathan is giving two conference talks at Crowd Supply’s Teardown 2023 June 23-24 in Portland, Oregon:    Make Your Own MCU Board    Build HackerBox #0040 and Wield the PIC of Destiny!   He spoke recently at the Embedded Online Conference about Object Oriented Programming (well, really good design practices). He has a  related github repository so you can look at the examples for yourself. He also gave a workshop on creating a simple command line interface (another excellent github repo full of examples). Probably the best place to start is his Embedded for Everyone Wiki where he collects all the bits and pieces you might want to know about getting into embedded systems. Transcript

453: Too Dumb to Quit

Julia Evans spoke with us about how computers compute. We discussed number representation including floating point as well as Julia’s extensive collection of ‘zines and comics. Julia’s zines about debugging, managers, Linux commands, and more are available on WizardZines.com. If you want samples, check out the comics section. Also, the experiments (aka playgrounds) are great additions to the zines (and fun on their own), letting you explore without changing your own DNS or removing all the files from your root directory. If you want to check out numbers, look at  memory-spy (or from other sites like https://float.exposed/ and https://integer.exposed/) Julia also has a detailed blog on jvns.ca and active github repositories Transcript

451: From Concept to Launch

Kari Love joined us to talk about soft robotics, robots in religion, and squishiness. Kari co-authored  Soft Robotics: A DIY Introduction to Squishy, Stretchy, and Flexible Robots. Her website is karimakes.com. She was previously on Embedded 189: The Squishiness Factor One of the pneumatic drives that we mentioned was a Hackaday Prize Winner: FlowIO. Another was the Soft Robotics Toolkit. However, Kari recommended Amitabh Shrivastava’s Programmable Air (Crowd Supply page for Programmable Air). Some search terms for getting started with soft robotics: “DIY Jamming gripper”,  “Positive pressure gripper”, and “bendy straw robot joints”. (That last one leads you to the delightful video Make a Robotic Hand with Straws.) Polysense conductive dye for making sensors out of found objects. (On Hackaday.) Simulation of Soft Bodies in Real World Applications (for squish and stretch) include SOFA, Abaqus, and DiffPD. Transcript An incomplete list of power systems people have used for generating soft robotic motion:   Pneumatic - air and vacuum   Hydraulic - using liquid   Electrical - using currents   Thermal - using temperatures   Cable control - using motor control   Magnetic - using magnets   Chemical - using reactions   Photonic - using light   Biological - using living cells   Hybrid systems - multiple sources in tandem     An incomplete list of things people have used to make soft robots:   Fabric   Silicone or other rubbers   Flexible plastic   Plastic films   Metallic films   Paper   Carbon fiber   Silly Putty   Shape-changing alloys   Electroactive polymers   Liquid metals   Gelatin or Gluten   Cell tissue

30: Eventually Lightning Strikes

Jonathan Bradshaw spoke with us about working with hardware engineers, schematic reviews, and FPGAs. At the end of the podcast, Jonathan made a pitch for folks to submit proposals for the IEEE Southern Power Electronics Conference in Auckland in December. The FPGA boards Elecia mentioned were the XLR8 board and the Papillio platform (more on the latter in show #66). By the way, The Amp Hour is our “enemy podcast” but we actually like their show quite a lot. It is a joke. But do feel free to tweet their shameless advertising tweet with the link replaced with one to our show.  And weta are neat! (Image, wiki)

He was a columnist for The C/C++ Users Journal, Embedded Systems Design and several other publications. He also served as secretary of the ANSI and ISO C++ standards committee in its early years.  We touched on some of his articles:  Poor reasons for rejecting C++ Preventing dynamic allocation Calling constructors with placement new  Andrei suggested Sams Teach Yourself C++ in One Hour a Day, Seventh Edition by Siddhartha Rao as a good primer for experienced C programmers reluctantly learning C++. NOTE: The contest already ended.

94: Don't Be Clever

James Cameron of One Laptop Per Child (OLPC) tells us about Forth, science fiction, and laptops. We have some tickets for ARM's mbed Connect conference is Oct 24, 2016 in Santa Clara. Will you be in the area? Want to go? Contact us if you want one of our free tickets! (There are still some tickets remaining.)  One Laptop Per Child is one.laptop.org.  Some getting started information on Forth: Mitch Bradley's Forth and Open Firmware Lessons James has been writing about putting C Forth on a Teensy (more on the Teensy from the creator's site). He also has a post on using Forth to snoop the Milo Champions Band's BLE.  James is Quozl on most sites that require a unique ID (such as Github:  https://github.com/quozl). This is from a book called Quozl by Alan Dean Foster. The other older-sci-fi reference was to the Pern books by Anne McCaffery, specifically to the White Dragon.

52: Maximize the Sonic Boom

Atmel’s Andreas Eieland (@AndreasMCUguy) spoke with us about low power chips and benchmarks, including tips for measuring and achieving the lowest power possible. EEMBC has a low power benchmark: ULPBench. EETimes wrote up a great introduction to the benchmark. Atmel’s SAM-L posted some excellent numbers for ULPBench. Chris wanted to look at processors between Cortex-M4 and phone chips. Andreas suggested the SAM7, SAM E, and Cortex-A5.  Programmable logic blocks (Look Up Tables) Coding tips and tricks for AVR micros (most things apply for all embedded development) App Note:  Ultra Low Power Techniques App Note:  Performance Levels and Power Domains Andreas was also on Episode 15: Robot on the Front, speaking about how the AVR processor line came to life, why there is an AVR in Arduino, and the spirit of making things. The Planet contest ends Friday June 12 (at midnight your time). Check out their jobs and send in your contest entry. Also, check out  Elecia’s BLE Intro.

36: Drive the Boat with a Wii Mote

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.

Chris and Elecia talk about <a href="http://en.wikipedia.org/wiki/Memetics" rel="nofollow" target="_blank">memetics</a>, learning, and processors.  Elecia was coy about the Pasadena party May 9th and 10th, but <a href="http://hackaday.com/2015/04/20/hackaday-los-angeles-event-develop-your-hacking-superpowers/" rel="nofollow" target="_blank">Hackaday announced it</a> so you can <a href="http://worldwide-la.hackaday.io/blog" rel="nofollow" target="_blank">invite yourself</a>.

98: Figments of My Imagination

James Grenning (@jwgrenning) returns to discuss TDD, Agile, and web courses.  James was on Embedded.fm episode 30: Eventually Lighting Strikes. James' new company is Wingman Software. His excellent book is TDD for Embedded C.  James suggested Training From the Back of the Room! as resource to people looking to put together a class. He uses and recommends CyberDojo as a coding instruction tool. Before Agile was Agile-for-business, it was Extreme Programming. James recommends Extreme Programming Explained. James will be the keynote speaker at AgileDC in October.

307: Big While Loop

Chris (@stoneymonster) and Elecia (@logicalelegance) chat about the year 2038, their projects, their new finds, and future shows. The year 2038 problem is real. Elecia read some of this tweet thread about it. Single file libraries list on github: (https://github.com/nothings/single_file_libs), including the STB image handling library Chris was originally looking for. Chris is working on a MIDI project with a NUCLEO-144 (STM32F303ZE) board and various breakout boards from Adafruit and Sparkfun. Elecia talked about the NASA Innovative Advanced Concepts Program (NIAC) and  curved crease origami. She also talked about PID controllers and Tiny ML. We are now soliciting sponsorship!

319: Squidly Tentacles

We talked to Craig Cook about learning embedded systems. He recently attended an embedded edX course through University of Texas.   The microcontroller and boards used in the course Craig's next course will be Interactive Python through Coursera As we discussed Craig's alarm clock we mentioned many parts including:  FM Module ESP8266 WiFi Module Electric Imp (Sparkfun or Digikey, don't forget the April breakout board)  Chris has also been looking at Particle.io's Photon board for WiFi + cloud development. This will be mentioned on other shows (as well as on The Amp Hour).

Christopher (@stoneymonster) and Elecia (@logicalelegance) babble about their current projects involving ants, guitars, machine learning, and party planning. A video of Christopher’s ants Some tweet threads about our tour of Santa Cruz Guitar Company.   Arrival (also: very old wood)   Wood is awesome   Adding science to precision craft   Elecia has been reading  Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow by Aurélien Géron. While the 2nd edition preview is on  O’Reilly’s electronic library (formerly Safari Online), it will be available via Amazon on July 5th. Or pick up the first edition. Phillip Johnston of Embedded Artistry (290: Rule of Thumbs) is looking for blog posts, exchanging editing and exposure for posts that make sense on the site. Contact him with a topic idea before jumping in. For the Embedded blog, related to the show with Phillip, Elecia wrote a post about learning to give feedback. Listener Brian asked about a CS degree for going into firmware. We mentioned our show with Dennis Jackson (211: 4 Weeks, 3 Days). Listener Craig asked about PICs. We suggested taking a look at Jay Carlson’s Amazing $1 Microcontroller. We talked to Jay in 226: Camp AVR vs. Camp Microchip. Listener Happyday asked about UL testing. We added FCC testing then asked if any of you could help us. Hit the contact link on Embedded.fm. Embedded has a Patreon. There are new sponsorship levels! Nothing has changed though.

26: The Tofu Problem

Professor Ayanna Howard of Georgia Tech joins us to talk about robotics including how androids interact with humans.  Some of her favorite robot include the Darwin, the Nao, and, for home-hacking, the Darwin Mini. Ayanna has a profile on EngineerGirl.org, a site that lets young women ask questions of women in the engineering profession. Elecia has been working on a typing robot named Ty, documented on the Embedded.fm blog. It uses a MeArm, on sale in July 2017 at Hackaday.com, with coupon noted in show. (don't use PayPal to check out or you can't apply the coupon).  Other robots for trying out robots: Lego Mindstorms (lots of books, project ideas, and incredible online tutorials!), Cozmobot, Dash and Dot. Some robotics competition leagues include Vex, Botball, and FIRST.

He has Savage Circuit TV which are the longer, more in depth videos and Short Circuit for the shorter ones. Also see his forums. Chris works for Parallax and had some kit suggestions: BOE-BOT (board of education bot), its successor the ActivityBot, and the ELEV-8 Quadcopter Kit. Chris is also a writer for Nuts and Volts. At the top of the show, we mentioned Chris' wife. Here is Ken Gracey's request for help. Or you can skip that and use the PayPal link on the Savage Circuits thank you page.
