Grow Light Diffuser

Cheap grow lights are great – they’re energy efficient, ubiquitous, and the design pattern of the aluminum-backed PCB for dissipating heat is well chosen. However, unshielded high-output LED’s are a real pain on the eyes.

I bought a set of these grow lights to give the plants in my bedroom a little boost since their window faces a shaded courtyard in the center of my building. Rather than invest in something more expensive or put up with hot pinpoints of light stabbing my eyes every day, I designed a cheap printed diffuser to make the system more hospitable.

Metal Parts from 3D Prints

After testing the Flat-Pack Camera Arm, I was pretty happy with the results. Happy, except for one detail: the joint at the base of the arm would creep down over time. This wasn’t a problem while taking shots of projects at the bench, given how often I’d have to reposition it. The big pain was trying to capture time lapses. The creep was just too noticeable, and it would never stay in place long enough to keep the action of a day’s work in frame.

“Iterating on Soft Robots” talk at Maker Faire

Kari Love and I gave a talk at Maker Faire last year detailing how the maker mindset (tinkering to get an intuitive sense of the rules governing the system, hands-on learning, fast frugal iteration, and sharing) can be transformative for research into fundamental technologies and chronically intractable problems.

The key factor is going from zero to a working understanding of the ground truths underlying the problem you’re trying to solve as quickly as possible. From historical surveys of how transformative technologies have been developed in the past (like TRIZ), deeply focused research is no match for playful learning and interdisciplinary exploration.

Super-Releaser has signed a book deal with Maker Media

Super-Releaser has begun work on a book on soft robotics for Maker Media. Kari Love and I are writing a book that provides a history of the field of soft robotics, tutorials demonstrating its basic principles, more sophisticated projects like a control system and entire soft robots, and the potential of applied soft robotics from medical devices to human spaceflight to interplanetary exploration. As far as we can tell this will be the first book published demonstrating practical soft robotics.

Glowy Crystal Ring

Do you like 3D printing, mold making, industrial design, jewelry, and RGB LED’s? You’re in luck, then. I just finished this tutorial for Adafruit and think it’s well worth a look.

In this project, I attempted to make an Arduino powered device that was easy to use, easy to make, and self contained. Every 3d printed component can be done in a single build without support material. The ring has a battery, switch, and USB port. Once it’s together, all you need to charge or reprogram it is a USB Micro cable.

Print Your Own Robot: Part 10

Long time no see, folks. I’ve got some great news for you. I’ve finally found a method for getting super complicated geometry locked inside of a seamless skin. It’s taken a lot of prototypes to get here, but I think the results are more than worth the effort. There are some wrinkles to iron out (which I’ll get to below) but all in all I think I’m incredibly close to rapid-fire casting working quadrupeds, ready to go in just a few short steps after popping the mold. In other good news, I’ll be dropping some files very soon which should get you your very own working quadruped using any FDM printer. All you need is a Makerbot or similar, a few hours, and some casting materials to have an exact duplicate of my most sophisticated robot to date.
