Embedded

On Skid Row in Los Angeles, where thousands of poor, homeless people live — many of them black — questions of how police should use force and interact with people come up all the time. We embed with both the police and the locals after the police shot and killed an unarmed black man. And we see what police tactics, from glad-handing to tough love, look like up close.

El Salvador is the murder capital of the world, by many estimates. It has the highest homicide rate anywhere outside of war zones. The reason? Violent street gangs, exported from the U.S. We spend 24 hours in the capital city, San Salvador, when the gangs try to flex their muscle like never before.

Micah Elizabeth Scott (@scanlime) joined us to talk about her new art and engineering projects. Micah's site is misc.name/ and her YouTube channel is micahjd. She launched a Patreon page. Wiggleport has its own site (wiggleport.org) and github (github.com/wiggleport). Check out the art in the repo! The Bela project on kickstarter has some overlap. Micah will be keynoting the 2016 Open Source Hardware Summit in Portland in early October. Her Eclipse project (video) was at the NEAT exhibition at the Contemporary Jewish Museum in San Francisco, CA. Micah has been on Embedded.fm before: 101: Taking Apart the Toaster (mostly about Coastermelt) and 41: Pink Universes Die Really Quickly (mostly about FadeCandy). Micah mentioned Boldport and the kit-of-the-month club. (Video of her building the first one!) Also: the BigClive channel on YouTube. Thank you to Planet.com for sponsoring the contest.

A shootout last year in Waco, Texas between rival biker groups the Cossacks and the Bandidos ended with nine people dead, 20 injured, and a lot of questions. Hear bikers give eyewitness accounts of the shootout and their predictions for what's next in this "war." Find Kelly McEvers on Twitter @kellymcevers. Email us at [email protected].

Philip Freidin (@PhilipFreidin) spoke with us about his BLE platform OSHChip, debuggers, and consulting. Planet Labs is sponsoring a contest! Hit the contact link to enter. Also check out their careers page and apply to [email protected]. Both the OSHChip and the CMSIS-DAP SWD programming module are on Philip's Tindie store. While Keil is the suggested compiler for now, you can also use mbed (tutorial). The system is wholly open source, you can find everything at github.com/oshchip. (Philip gave an HDDG talk about OSHChip; we didn't talk about it but I thought it was interesting.) Philip's company is Fliptronics. Under Tips and Tricks, that site has his advice on consulting.

Kelly McEvers (@kellymcevers) joins us to talk about the definition of embedded. Kelly McEvers is one of the hosts of All Things Considered, NPR's award-winning afternoon news magazine. She is also the host of a new podcast called Embedded which takes a story from the news and goes much deeper into it. Her Embedded podcast launches on March 31st. Subscribe now on iTunes, listen on NPR.com or your favorite podcast app. Kelly's Diary of a Bad Year: A War Correspondent's Dilemma is an amazing listen. Kelly mentioned her interview of a drone pilot, Lt. Col. T. Mark McCurley, author of Hunter Killer. She also interviewed Sarah Pennypacker, author of Pax. Elecia does not squee on air. But it was a near thing.

Christopher and Elecia chat about the Hackaday prize, Unity class (and their games), the blog, hams, and IDEs. Embedded.fm blog posts we discussed: Chris wrote about ham radio practice tests and his plane's maiden flight. Elecia is working her way through her book about taking apart toys. Chris Svec is taking a microprocessors approach in Embedded Systems 101. And Andrei's current Embedded Wednesdays posts have been about number format and accelerometer output. Sign up for the Embedded.fm newsletter to get blog content in your email box. Hackaday Prize! Yay! Sign up early and often. Chris and Elecia have been taking a Unity course on Udemy (pricing becomes more sensible after April 1). Elecia's game is live for the next 30 days, you can play it from your computer's browser (but not Chrome). Audio "enhances" the experience. Also: you were warned. Atomic Game Engine is another game engine but open source. Justin has 8 reels of 800 of Atmel AT32UC3A3256S-ALVR. Let us know if you'd like to be connected. Elecia liked the Ed Emberley Make A World drawing book. Bipedal robots at RobotShop.com for software programming or SparkFun's Redbot kit for more hardware oriented fun. If you missed last year's April Fools Embedded.fm: The Elon Musk of Earth. Feel free to listen to it again on April 1 as there will be no such gag this year.
