510: The Secret Chip

Christina Cyr spoke with us about building cell phones, entrepreneurship, social purpose corporations, awards, lithium recycling, and her interesting career path.  We talked about Christina’s Cyrcle Phone, the related kit from dTOOR, and her CES Innovation Award. We also mentioned Fairphone in the section about social purpose corporation. There is a great paper from Nature about lithium-ion battery recycling: The evolution of lithium-ion battery recycling | Nature Reviews Clean Technology Christina Cyr Personal Website  Wellfound (formerly AngelList) is a startup focused job site that may lead to non-fulltime positions. Crunchbase may help you figure out is the startup has capital (also Pitchbook thought that generally has a cost). ADH connectors by JST and the SparkFun JST Battery Removal Tool The quote was from Hemlock & Silver by T Kingfisher and it was a lovely fantasy mystery with an incredible first chapter. Note: there are some audio artifacts on Christina’s track, we apologize as there was a technical issue that couldn’t be resolved. We’ve tried to clean it up with post-processing.

506: How Do I Fit a Whale Into an Apartment Building?

Dmitry Grinberg joined us to talk about running Linux on small microprocessors (physically small and/or 4-bit). Dmitry does this by emulating a MIPS processor. Boot times vary between minutes and days, depending on the processor.  Dmitry’s projects are on his website (dmitry.gr) including: 8-pin Linux (Cortex-M0+!) Linux on an 8-bit micro? Linux/4004 Dmitry recommended NandGame, an online game about building up a processor. We mentioned Eric Schlaepfer of TubeTime. He was on the show on 419: Fission Chips, with EMSL’s Windell Oskay, talking about their book Open Circuits.
