I’ve been playing with origami, lately. Specifically, I’ve been exploring how to simulate, model, and fold origami shapes in ways that could be automated to create useful mechanisms. The system I’ve come up with is designed to fold rip-stop nylon, which I’ve worked with a bit during my time at Makani Power and research at Super-Releaser.
After some experiments with programs designed specifically for generating origami patterns, I found I wasn’t able replicate the patterns I’d prototyped in paper. Since I wanted to start out with a paper prototype, do some bench tests, and move to CAD from there, I needed to consider other options. I also wasn’t able to convert the output into a format that would play with CAD for printing and prototyping the resulting forms. So, I fell back on my old standard: SolidWorks. If you’ve worked with me before or you’re a regular reader, you don’t get any bonus points for guessing I’d find a way to turn this into a SolidWorks project. This video was very helpful for understanding how to think about origami in a SW context.
I developed this static mixer design to streamline casting demos. Often times, a casting demo can get bogged down with portioning, mixing, and degassing, especially when you’re trying to have a group of students get hands-on time with the casting materials.
With this design, you load up degassed silicone, store the unit until needed, and then dispense mixed material out of the nozzle. If you’d like to build your own, you can find all of the source files on Thingiverse. This project was also picked up by Hack A Day.
I’ve been experimenting with printed flexures, and wanted to make a simple tensegrity toy to explore the concept. This design (which you can download on Thingiverse) features both printed tension and compression elements that all build together into a slightly bouncy tensegrity sculpture.
I also optimized the design to allow everything to print at once on my Ultimaker 2+ buildplate. The sculpture assembles with a handful of self-threading torx screws to make it easy for anyone to replicate.
The Adaptiv is a futuristic sneaker design that features soft robotic elements to maximize performance while running, jumping, and breaking ankles on the court. The design was spearheaded by Jordan Diatlo of Leadoff Studio for the athletic data company SOLS. The project also featured research and development work by biomechanical engineer Richard Ranky. Super-Releaser contributed to the overall project, building a physical prototype that displayed the soft robotic mechanisms that dynamically adjusted the shoe’s fit and springiness intended to maximize performance during a game.
Leadoff deserves a ton of praise for designing the digital and physical elements in time to premiere at the NBA All-Star Week. I’d like to congratulate everyone who contributed to the project for their hard work and adventurous thinking, bringing such an unusual futuristic design to life. Also, I have to thank Jordan for bringing me in on the process and directing the show.
Makezine (and author Caleb Kraft) were kind enough to do a Maker Spotlight interview with me. In it, I was able to talk about my perspective on problem solving, mechanical design, and multidisciplinary research.
From the article:
I’m also really proud of the microscopic tardigrade aquarium I made for Midnight Commercial and Google ATAP. It was this microlens-array powered microscope that looked into a tiny self-contained biome of waterbears, algae, and other microscopic critters we mixed up as an artificial biome – all designed to live in your phone and let you watch this little world through your screen. I got to do everything from design biological research experiments, to diving into whitepapers on micro-optics and tardigrade lifecycles, to simulating EDM cut sheet metal flexures, to figuring out how to cheaply duplicate micro-machined lenses using silicone casting.
I was hired by SOLS to help out with their Adaptiv project. The idea was to showcase the procedural modeling techniques, materials, and technologies behind their printed insoles with a futuristic robotic shoe. Jordan Dialto, the industrial design lead at SOLS, approached me in my capacity as lead scientist at Super-Releaser to make a prototype soft robot shoe that could change shape and fit in response to the wearer.
The project started out with an external shell modeled by Continuum Fashion. Although the design was elegant, this posed a challenge for introducing the robotic elements and the engineered components that would stitch everything together. Since the external shell was generated in a mesh CAD program, it didn’t fit into SolidWorks’ reference frame. This meant using the mesh as a reference and generating a simplified surface to extrude the soft robot elements and retaining skeleton from. Continue reading →
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.
To start, the building used to be an IBM adding machine factory and showroom. When JJ’s took it over, they installed a lovely wood exterior. So, on the plus side, there is a lot of old NYC richness both inside and out. On the downside, the wood exterior had fallen apart in the intervening years. Part of my job was to see through the decades of wear and tear and come up with a plan for refurbishing everything to resemble the original without spending thousands on custom parts. Fortunately my friend Clark put me in touch with a few very talented carpenters. So, with some meetings and design drawings, they were rolling on building the elements for the exterior.
