Jeff Keyzer (@MightyOhm) joined us to talk about consumer manufacturing, how to solder, and having a full time job and a kit company. Jeff's blog is on MightyOhm.com. The Geiger Counter kit is available at MightyOhm.com/geiger. The really, really useful Soldering Is Easy comic book is MightyOhm.com/soldercomic. At Valve, Jeff worked on the Steam Controller (hardware specs at bottom of the Valve page or for sale on Amazon). There is also a neat video showing the manufacturing automation in action. We mentioned Glowforge, Dan Shapiro was on episode 125 (and if you are going to buy one, please consider using our referral link!) Elecia and Chris have a Hakko FX-888 soldering iron. Jeff suggests Kester 186 flux which you can get in smaller-than-giant containers on eBay. No, not the pen on Amazon. Or maybe the MG Chemicals 835 (which is in little bottles on Amazon). Flux seems like a very personal thing.
