Got a lot of interest at Maker Faire, so I've gone ahead and posted the files in their current state. Not final, and it will be hard for anyone to build one until I put together a BOM and maybe some instructions, but they're there for those who want to take a look.

Weird issue, I tried activating Z lift, and suddenly my prints looked underextruded and were stretched vertically. It looks like it is lifting on a G10, but not dropping back down on a G11. Anyone seen this before?

I've been building a little something.

I'm calling it the Cranestyle Mini.

We've posted module 1 of our (+Whosa whatsis and my) Hacker Calculus project - a little Circuit Playground based device you can make to visualize acceleration. Details on the device:

Does Youmagine support Markdown or not? Every time I try to format something, it looks fine in preview, but the formatting doesn't show up on the published page. Even the links don't work unless I just include the URLs as text. I also wanted to embed a youtube video of the design in action. That showed up in the preview but on on the page as well.

I made a blinky.

I'm looking for a purely-mechanical mechanism that will keep two rotating shafts at the same angle with a variable distance between them. The best ideas I've come up with so far are a pair of 4-bar mechanisms attaching to a third point or putting a keyed linear shaft through the two with bevel gears or universal joints, but is there anything better? I don't need full rotation, just 180 degrees. Any ideas?

Latest book (our sixth!) in collaboration with +Whosa whatsis is now available for preorder. Some pretty cool models!
