277: The Sport of Kings

February 07, 2019 by Elecia White

Jie Qi (@qijie) spoke with us about making paper-based electronics (@Chibitronics) and learning about patent law (via @Patentpandas).

Jie Qi is the founder of Chibitronics, a crafting electronics platform that uses paper and stickers to create (and teach) circuits. Building the company and working on electronics-filled pop-up books led to the realization that patent law does apply to open source maker-type companies. She started PatentPandas.org to share what she’s learned.

Jie is not the only one who has had issues with big companies patenting their open source work. We mentioned Jarek Duda and his fight to keep his compression algorithm unburdened by patents.

If you are having or wondering about having an issue, Patent Pandas is intended to be an amusing and gentle introduction. If you are looking for prior art, you can look at the Prior Art Archive and Patents.StackExchange. (If you have some free time, there are often requests to find prior art.)

If you are a maker wanting to ensure that your work has dated prior art, submit it to the Wayback machine (Archive.org).

276: Playing a Song on a Potato

January 31, 2019 by Elecia White

Jesse Rutherford (@BentTronics) gave us an in-depth look at the 555 timer IC (wiki).

Jesse runs Bent-tronics.com and wrote The Ultimate Beginner's Guide to the 555 Timer (Amazon).

Some great 555 projects:

555 Decimal Adding Machine
555 found in a drill trigger speed controller as seen on the Ben Heck Show
555 found inside a solar charger controller, video by Julian Ilett

Somehow, despite it being in the plan, we didn’t mention the Evil Mad Scientist The Three Fives Kit: A Discrete 555 Timer which builds a 555 Timer out of discrete parts. If only the creator would come on to talk about it and his other cool projects. Note that EMS also has a great description of how the 555 timer works.

The giveaway is Jesse’s book and the components to build the projects in his book.

275: Don’t Do What the Computer Tells You

January 24, 2019 by Elecia White

Janelle Shane (@JanelleCShane) shared truly weird responses from AIs. Her website is AIWeirdness.com where you can find machine-learning-generated ideas for paint colors, ice cream, and cocktails (and many other things). We never said they were good ideas.

Janelle’s FAQ will help you get started trying out RNNs yourself. We recommend the Embedded show titles.

We talked about BigGAN which generates pictures based on input images.

Janelle’s upcoming book is You Look Like a Thing and I Love You. Sign up for her newsletter to be the first to order it (as well as getting the PG-13 versions of her hilarious AI outputs).

274: Swiss Knife of Embedded Systems

January 17, 2019 by Elecia White

Ivan Kravets (@ikravets) spoke with us about PlatformIO (@PlatformIO_Org), IDEs, embedded libraries, and RISC-V.

PlatformIO is an editor, an integrated development environment with debugging and unit testing, and/or a library index. Its goal is to make embedded development easier and more consistent across host operating systems and development hardware. It is also a .org because the goal is to make all of this open source and free to engineers.

Ivan Kravets is the founder of PlatformIO.org. Personal site, Github, LinkedIn, and a neat interview. He recommends seeing the Dnieper River if you are in his area.

Ivan recently attended the RISC-V Summit. RISC-V is an open source processor core (like ARM but open source). SiFive was mentioned as one of the RISC-V processor vendors. RISC-V is being used extensively in research. Western Digital is planning to develop RISC-V based controllers. And MIPS recently joined RISC-V.

273: Off the Topic of My Jammies

January 10, 2019 by Elecia White

Chris and Elecia chat with each other about the new year. All is fine until she starts quizzing him about some language details of his new project.

Many object-oriented resources suggest using composition (has-a) over inheritance (is-a-type-of) (wiki). Where do swift extensions fit in? It seems to me (Elecia here) that extension is invisible composition that allows adding of functions.

For example, say you want a TiltSensor and you already have an ImuSensor object so you need to add a function for TiltComputation.

You could make the TiltSensor contain an ImuSensor (composition). You call the ImuSensor functions to check the readings when running TiltComputation function. You don’t need to know what is in ImuSensor, only what the API is.

You could have TiltSensor be a child class of ImuSensor (inheritance) so that TiltSensor responds to all ImuSensor functions as well as its new TiltComputation function. You could use the variables in ImuSensor directly for TiltCompulation but you will need to know what is in ImuSensor for that to work.

Or, in Swift, you could have TiltSensor be an extension of ImuSensor. Except it wouldn’t be called TiltSensor, it would be part of ImuSensor: any file that had access to your extensions would be able to create an ImuSensor instance and call TiltComputation as if it was part of the original ImuSensor API. The TiltComputation function would only have access to its extension’s variables and ImuSensor’s API. You get to add new functionality without breaking backward compatibility.

271: Shell Scripts for the Soul

December 20, 2018 by Elecia White

Alex Glow (@glowascii) filled our heads with project ideas.

Alex is the Resident Hardware Nerd at Hackster.io. Her page is glowascii and you might want to see Archimedes the AI robot owl and the Hardware 101 channel. They have many sponsored contests including BadgeLove.

Lightning round led us to many possibles:

It you were building an IoT stuffed animal, what would you use? Mycroft and Snips are what is inside Archimedes.
If you were building a camera to monitor a 3d printer, what would you use? For her M3D Micro Printer, Alex would use the Raspberry Pi based OctoPi to monitor it.
If you were going to a classroom of 2nd graders, what boards would you take? The BBC Micro:bit (based on Code Bug) or some LittleBits kits (Star Wars Droid Inventor Kit and Korg Synth Kit are on Amazon (those are Embedded affiliate links, btw).
If you were going to make a car-sized fighting robot, what dev system would you use? The Open Source Novena DIY Laptop initially designed Bunnie Huang

There were more software and hardware kits to explore:

For your amusement Floppotron plays Bohemian Rhapsody

Alex gave a shout out to her first hackerspace All Hands Active

Ableton is audio workstation and sequencer software. Alex recommends Women’s Audio Mission as a good way to learn audio production and recording if you are in the San Francisco area.

There is an Interplanetary File System and Alex worked on a portable printer console for it.

Elecia is always willing to talk about Ty the typing robot and/or narwhals teaching Bayes Rule. She recommended the book There Are No Electrons: Electronics for Earthlings by Kenn Amdahl.

270: Broccoli Is Good Too

December 13, 2018 by Elecia White

James Grenning (@jwgrenning) joined us to talk about Test Driven Development, dealing with legacy code, and cleaning out very large pipes.

James is the author of Test Driven Development for Embedded C. If you want to take his live online course, check out the remote delivered TDD classes on Wingman Software. His blog has many great articles including TDD How-to: Get Your Legacy C into a Test Harness and TDD Guided by ZOMBIES.

Book: Working Effectively with Legacy Code by Michael Feathers

James mentioned Given-When-Then, a testing design pattern (brief intro). Kent Beck also wrote about test && commit || revert style testing.

James and Bob Martin present IoT implementation strategies in a series of videos on Clean Coders. James mentioned working with a Synapse Wireless radio.

269: Ultra-Precise Death Ray

December 06, 2018 by Elecia White

Alan Cohen (@proto2product) wrote a great book about taking an idea and making it into a product. We spoke with him about the development process and the eleven deadly sins of product development. We did not talk about ultra-precise death rays.

Books we discussed:

Alan’s Prototype to Product: A Practical Guide for Getting to Market
Elecia’s Making Embedded Systems
The Mythical Man-Month, Anniversary Edition: Essays On Software Engineering by Frederick P. Brooks Jr.
The Manager's Path: A Guide for Tech Leaders Navigating Growth and Change by Camille Fournier

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 1982 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.

268: Cakepan Interferometry

November 15, 2018 by Elecia White

After many bouts of lightning round, we finally got our lightning questions answered by Eric Brunning (@deeplycloudy). Eric is a Professor of Atmospheric Sciences at Texas Tech University specializing in storm electrification and lightning .

You can hear some of Eric’s field adventures by listening to his episode of the Don’t Panic Geocast show.

The Wikipedia page for lightning will lead you down many strange pathways. Though the Wikipedia Lightning Energy Harvesting page may convince you that it isn’t feasible (though some math might as well, as discussed on this show).

For more about lightning interferometry, check out Michael Stock’s in-depth site.

You can hear lightning on Jupiter if you listen to the right bands.

Neat video of the Milky Way in radio waves reflecting off the moon

Elecia really enjoyed The Cloudspotter’s Guide by Gavin Pretor-Pinney.

267: Cute and Squishy

November 08, 2018 by Elecia White

Lindsey Kuper (@lindsey) spoke with us about !!Con West, being a new professor, and reading technical journals.

The call for speakers for !!Con West is open until November 30, 2018. The conference will be in Santa Cruz, CA on February 23-24.

266: Drive off the End of the Universe

November 01, 2018 by Elecia White

Chris (@stoneymonster) and Elecia (@logicalelegance) talk about conferences, simulations, and future episodes.

Simulation/Emulation: QEMU and Renode. Chris also noted there were QEMU for STM32 instances such as this one from beckus.

For conferences, we named several but had no particularly useful advice. We did recommend classes such as James Grenning’s training on TDD in Embedded Systems and Jack Ganssle’s Better Firmware Faster.

There are several (free) machine learning courses available from Udacity including Intro to Machine Learning which was part of the Self-Driving Car series that Elecia took.

The future basics episodes were grouped into:

Flow of program control (pre-RTOS)
Design patterns
RTOS information

Noah Leon made a film: Love Notes to Newton. It features the people who love and the people who built the Apple Newton. We spoke with him about the Newton and about filmmaking.

Noah runs Moosefuel Media. He wanted to mention Frank Orlando of OrlandoMedia, the art designer for the film and promotional material. Profits from Love Notes to Newton go to Be The Match, a registry of bone marrow donors.

You can sign up for the Newton mailing list at NewtonTalk.net. The book about the Newton development is Defying Gravity: The Making of Newton by Markos Kounalakis. The documentary about Compaq is Silicon Cowboys (Netflix).

261: Blowing Their Fragile Little Minds

September 21, 2018 by Elecia White

Helen Leigh (@helenleigh) is an author, education writer and maker. She spoke with us about making learning fun (and subversive).

Her latest book is The Crafty Kid's Guide to DIY Electronics, out in November 2018.

The instrument gloves were the mi.mu (full version) and the mini.mu DIY kit (coming soon to Pimoroni and Adafruit). The mini.mu uses the BBC Micro:bit.

Helen worked on earlier books including Mission Explore from the Geography Collective. These are out of print but still obtainable (and may be in your local library).

She recommends the book The Subversive Stitch: Embroidery and the Making of the Feminine. For meeting people in education and technology, Helen is looking forward to the next EMF Camp. As far as tech and education conferences, the BETT trade show is interesting.

We mentioned “Phoenix” a few times, that is Phoenix Perry who was on episode 204: Abuse Electricity.

260: We Talked a Lot
