Hackaday Links: July 23, 2017

Hey, you know what’s happening right now? We’re wrapping up the third round of The Hackaday Prize. This challenge, Wheels, Wings, and Walkers, is dedicated to things that move. If it’s a robot, it qualifies, if it’s a plane, it qualifies, if it passes butter, it qualifies. There’s only a short time for you to get your entry in. Do it now. Superliminal advertising.

Speaking of the Hackaday Prize, this project would be a front-runner if only [Peter] would enter it in the competition. It’s one thing to have a cult; I have a cult and a petition to …read more

Soluble Molds For Composite Parts

People have been experimenting with 3D printed molds for fiberglass and carbon fiber for a while now, but these molds really aren’t much different from what you could produce with a normal CNC mill. 3D printing opens up a few more options for what you can build including parts that could never be made on any type of mill. The guys at E3D are experimenting with their new dissolvable filament to create incredible parts in carbon fiber.

For the last year, E3D has been playing around with their new soluble filament, Scaffold. This is the water-soluble support material we’ve all …read more

My DIY BB-8: Problems, Solutions, Lessons Learned

Imagine trying to make a ball-shaped robot that rolls in any direction but with a head that stays on. When I saw the BB-8 droid doing just that in the first Star Wars: The Force Awakens trailer, it was an interesting engineering challenge that I couldn’t resist. All the details for how I made it would fill a book, so here are the highlights: the problems I ran into, how I solved them and what I learned.

The Design Criteria: Portable and Inexpensive

I had two design criteria in mind. The first was to keep it low-cost. Some spend $1000 …read more
