Embedded

Andrei Chichak joins Elecia and Christopher to do a deep dive into the world of interrupts.

Andrei writes on our blog: Embedded Wednesdays. He has written specifically about interrupts in multiple ways: general introduction, buttons and debouncing, peripheral data transfer via DMA, and so on). The knock-knock joke comes from Chris Svec’s Embedded.fm blog post on interrupts.

Christopher (@stoneymonster) and Elecia (@logicalelegance) chat about listener questions and things they’ve been up to.

A listener turned Chris on to Ray Wilson and his Music From Outer Space website on DIY analog synths and book Make: Analog Synthesizers. After collecting parts for a total DIY, he found and built a neat kit: Kastle Synth (as heard on the show) and has connected it to his Roland SE-02 Analog Synthesizer (on Amazon). BTW, his ham radio WSPR kit is the Ultimate 3 in case you are behind on hobbies. You can hear more about it in 197: Smell the Transistor.

Elecia has been working through Udacity’s Self-Driving Engineer nanodegree. She completed term 1 with its computer vision and machine learning and is on to term 2 with sensor fusion, localization, and control. She blissfully is unaware of the cost because she got to be an industry expert for the Intro to Self-Driving Cars course.

Listener Simon asked about non-fiction books. Elecia gets many of hers by looking at what is on discount at BookBub’s science section which lead to two books she highly recommends Spirals in Time (snail facts) and Tristan Gooley’s How to Read Water (beach explainer).

Chris has been reading Scott Wolley’s The Network: The Battle for the Airwaves and the Birth of the Communications Age and How Music Works by David Byrne.

Some show-related recommendations include Gretchen Bakke’s The Grid (hear Gretchen on episode 213: Electricity Doesn’t Behave Like an Apple) and Jimmy Soni’s Mind at Play (hear Jimmy on episode 221: Hiding in Plain Sight). She’s reading Tim O’Reilly’s WTF book about the future in anticipation of an upcoming episode. That's a good reminder: we, of course, also recommend Making Embedded Systems.

Zach asked about Michael Barr’s Embedded Software Training in a Box. Apologies if we weren’t specific enough, it would likely make a better blog post.

Also: $1 Microcontrollers!

Jonathan Beri (@beriberikix) spoke with us about his double life: Particle.io product manager by day, maker by night (and weekends).

Jonathan wrote a chapter about piDuino5 Mobile Robot Platform in JavaScript Robotics.

Product manager resources from product.careers and Ken Norton's Newsletter. For an alternate take, there is good cartoon about effective product management from Henrik Kniberg.

For getting into open source lines, see the guide from Github. Also, there is a newi-sh consortium, the TODO group, with guides and resources about running open source projects.

There is also the often useful Google's developer documentation style guide.

Ben Hencke (@im889) spoke with us about OHWS, Tindie, and blinking lights.

Ben sells his Pixelblaze WiFi LED controller on his ElectroMage store on Tindie. It is based on the ESP8266 and uses the DotStar (APA102) lights.

To hear John Leeman’s trip report on the Open Hardware Summit (OHWS), listen to Don’t Panic Geocast, Episode 140 – “Juicero of Tractors”

Ben’s websites are bhencke.com and electromage.com. Go there if you want to see some of Ben’s projects, including Synthia. You can also find Ben on Hackaday, Github, and YouTube.

We talked with Charles Lohr about ESP8266 WiFi controlled lights and ColorChord on Embedded.fm episode 102: The Deadly Fluffy Bunny (With WiFi).

Jared Kushner has taken on a lot of responsibilities in the Trump White House, from tackling the opioid crisis to negotiating Middle East peace. But like many members of the administration, he has no previous government experience. In this episode, we examine Kushner's business dealings and his family's history to better understand how he might handle his government work.

Now that Steve Bannon has left the Trump Administration, he says he is waging #war against the Republican establishment in the name of populist nationalism. But before he got involved in politics, Bannon spent decades in Hollywood, and his time there can tell us a lot about the origins of his beliefs.

When Donald Trump came to Rancho Palos Verdes in Southern California in 2002, he was greeted as a "white knight." Trump was buying a golf club that had gone into bankruptcy when the 18th hole had literally fallen into the ocean. But what followed was a decade of public insults, lawsuits, and broken rules.
