I am Elecia White alongside Christopher White. We’re here to chat about the interests, careers, and lives of engineers, artists, educators and makers. Our diverse guest list includes names you may have heard and engineers working quietly in the trenches. Either way, they are knowledgeable, enthusiastic, and inspiring.
We’d love to share our enthusiasm for science, technology, engineering, art, and math (STEAM).
195: A Bunch of Sputniks
We discussed CubeSats with their co-inventor, Professor Jordi Puig-Suari, Professor of Aerospace Engineering at CalPoly SLO and co-founder of Tyvak Nano-Satellite Systems. The 2017 CubeSat conference is in San Luis Obispo, CA on April 26-28. More details at CubeSat.org. Information about CubeSats at CalPoly SLO can be found at PolySat.org. Tyvak is hiring for a number of different positions: tyvak.com/careers. For more satellite goodness, we spoke with Patrick Yeon of Planet about their CubeSat-based platform and deployment mechanism in Embedded episode 153: Space Nerf Gun. Thank you to Embedded Patreon supporters for Jordi’s microphone!
194: Something For Something
Shulie Tornel (@helixpea) joined us to talk about the 2017 Hackaday Prize (@hackaday and @hackadayio). Hackaday World Create Day is April 22nd, let them know if you want do a meetup so they can add you to the calendar. Elecia gave away all of her potential ideas, trying to figure out which one would work best for entry. It was probably Maxwell except for its lack of novelty (Embedded shows #17 and #54and there is a SparkFun Tutorial). Are you entering? The first phase (until May) is community driven (popularity contest). Post your entry here or tweet to us (@embeddedfm) and we'll like it. Also, it was Shantam Raj's Self-sustained Ultralow-power Node that we discussed in the show. Neon Demons (trailer) Embedded blog contributor Chris Svec was on the CodeNewbie podcast talking about robots and chip design. The following week Saron invited Elecia to record an episode about getting into hardware and embedded software.
