As usual, there are just too many choices, so you'll have to settle for just the few that can fit in a podcast. The guys were excited about 3D printing -- both FDM and SLA -- as well as a few camera projects. Ever wanted your own starship? They do, too, and you'll hear about it along with portable radar and more. Want to make flexible PCBs? Fill up a carbon dioxide tank? Or play Doom via regular expressions? Tune in, and you'll find out about those stories and more. Follow along with the links , and as always, tell us what you think about this episode in the comments!
