184: Not Likely, Possible, or Safe

Ben Krasnow (@BenKrasnow) spoke with us about prototyping, Patreon, and staying current. And a whole bunch of stuff.

January 28th Hats and Hacks Party RSVP

Ben’s YouTube channel is Applied Science. His recent videos have been shot with the high speed Chronos camera (whose creator David Kronstein was on The Amp Hour #325).

Ben has a Patreon page which funds randomness. (Embedded also has a Patreon page, for randomness and mics.)

Ben was previously on the show: 119: Do Your Neighbors Have Any Idea?

For BLE prototyping, Ben mentioned the OSH Chip by Philip Freidin (146: The Loyal Opposition) and using Processing for Android to make quick-n-dirty test applications.

We mentioned the Wazer desktop waterjet.

Chris brought up this video describing impedance with a mechanical model.

One of Ben’s favorite videos that he did was the first one with an electron microscope, way back in 2011: DIY Scanning Electron Microscope - Overview.

Ben gets a lot of his news from Hacker News: https://news.ycombinator.com/

Ben’s Twitter criteria was that they didn’t post updates often too often for his one-a-day check and that they focus on tech:

And some of his favorite YouTube channels (Ben said it was very difficult to distill as there are many great choices):

  • mikeselectricstuff
  • tesla500
  • Matthias Wandel
  • NightHawkInLight
  • The Signal Path
  • Techmoan

179: Spaghetti Reducer

Miro Samek (@mirosamek) of Quantum Leaps spoke with us about making better state machines through actor objects and hierarchical state machines.

Miro wrote a book: Practical UML Statecharts in C/C++: Event-Driven Programming for Embedded Systems. He has an excellent YouTube channel explaining embedded concepts. We discussed his video that describes how a stack overflow works and the related in-depth post on EmbeddedGurus.com.

Elecia enjoyed his object oriented programming in C PDF for both the OO and the UML refresher. 

Miro mentioned the Software Engineering Radio podcast. We mentioned our favorite podcasts blog post. Also, we talk about Jean Labrosse's recent episode of Embedded.fm.

 

 

 

178: Alexa Stop

We spoke with Chris Maury (@CMaury) about using speech recognition to interact with devices. 

Note: Please turn off your Echo and Dots as we invoke Alexa a lot

Chris is the founder of Conversant Labs. They created TinCan.ai which can help you wireframe or prototype a conversational user interface.  They can also help you build Alexa Skills, though if you are so inclined, you might try it for yourself: Alexa Skills Kit

Chris will be speaking at the O'Reilly Design Conference in San Francisco, CA in March 2017, giving a tutorial on building voice based user interfaces. You can read more from Chris on his Medium posts medium.com/@CMaury.

174: It's Not Weird

We spoke to Evan Shapiro, CTO and cofounder of Knit Health (@KnitHealth), about baby monitors, IoT security, neural nets, and professional poker.

The Knit Health Kickstarter ends November 17, 2016.

Evan recommended Google Tensor Flow and Python's Theano for an introduction to machine learning. (If those sound familiar it is because Kat Scott mentioned them as well.) Evan also suggested that if you'd like to know more about the history of neural nets, check out this post by Audrey Korenkov

If you'd like a gentle introduction, check out a Narwhal's Guide to Bayes' Rule.

Evan mentioned some videos he did about poker, they are on Card Runners (NOTE: it is a paid site with free tastes).

Final quote was from Neil Gaiman's excellent Graveyard Book.

172: Tell Forth You Me Please

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

 

 

171: Perfectly Good Being Square and Green

Saar Drimer of Boldport (@boldport) spoke with us about the crossover of art to electronics and building a business around it. 

Monthly, the Boldport Club ships aesthetically-pleasing electronics kits. We discussed past projects include The Lady and Touchy on the show. The seahorse board is on the blog.

Micah Scott (@scanlime) has entrancing videos of putting together the first club project (Pease) and second one (Superhero).

Saar uses PCBMode to create his circuits. He also wrote the tool. It is open source.

Cratejoy is used for the sales and shipping logistics.
