My first major find was the guys from Easel. They produced a CNC drawing software that handles all the GCode creation as well, plus it sends it to a Shapeoko CNC cutter, all in one software application. And it's Free! They basically created for CNC cutting what TinkerCad does for 3D printing and more. I thought it was still in Beta mode but it has apparently been officially released per the Easel guys. And who was there checking it out at the same time I was? None other than Ben Heckendorn of the Ben Heck show. We were both bombarding them with questions but Ben got to try it out first so I just watched. It's really awesome. I plan to add a Shapeoko to my lab so I'll have both 3D printing and CNC capability. They were routing out a circuit board when I first walked up.
3D printers have clearly taken over the Maker Faire. What was interesting is I saw very few electronics booths or Arduino booths other than the big Make Magazine tent. It appears that most of the electronics sellers with custom shields and boards that were at past Faires have either quit Maker Faire - Detroit or got sick of competing with the Make Tent. That is a shame because the first few years you could find just about any electronics you wanted. Raspberry PI was at a few booths but they were just showing something it could do. Arduino presence was not big either outside the Make Tent.
Overall, I thought it was another great Maker Faire - Detroit. Outside the weather was hot but perfect. Inside the museum was cool and crowded. The fact that it's actually in Dearborn, not Detroit, at The Henry Ford and costs $28 to get in for the day makes it the most expensive Maker Faire I know of. But people still crowd the place. I continue to be amazed by the crowds that this Faire draws. It is well worth the trip if you get a chance.
