3D Printed Syringe Static Mixer

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.

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.

You can download the design files and read the build instructions on Thingiverse.

As a bonus, they also provide some great Miami Vice lighting, just in case I wanted to film my own episode of ContraPoints.

Metal Parts from 3D Prints

After testing the Flat-Pack Camera Arm I built, 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 anywhere. The big breakdown 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 hacking in frame.

So, I set out to make some locking plates for the arm, and I think people could find some interesting uses for the process I came up with. The broad strokes of the method are that you design the part you’d like at the end in CAD, design a floor under your part with walls around it (I call this a bathtub), print the bathtub mold you designed, cast the mold using 2-part silicone (making sure it’s nice and level), and cast your final material into that mold. Once you’ve got the knack of replicating parts using 1-part molds, you can get fancier: adding vent holes for letting air escape or labels for your parts or building multiple parts for your molds for even more precise geometry.

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.

3d Print-able Sleep No More Mask

Stitching up the scans into a single surface.

Sleep No More is an incredible production: an immersive live performance staged on an expansive five story set inhabiting New York’s abandoned McKittrick Hotel [I have been informed that the bit about the set being built out of an abandoned hotel is just PR fluff… SNM actually takes place in a warehouse scratch built to look like an old hotel. The more you know]. I don’t need to sing its praises. Other folks have done so amply, effusively, and more successfully in other formats. Just Google it.

I saw it live a few months ago, and it’s stuck with me. I especially liked that I got to keep the mask I viewed the entire performance through. Being a rebel, I brought along a sharpie so I could give it incredulous eyebrows. Fuck the police.

The finished, watertight model, ready for printing.

I thought it would be fun to get more folks in on the action and share my favorite part of the experience, so I teamed up with the impossibly amazing Numidas Prasarn to scan, assemble, and release a life size 3d print ready version of the Sleep No More mask. So, here it is, on Thingiverse and ready to be played with. I intend to shrink it down into little Lego man helmets when I get the chance.

 

DIY Guy Fawkes Bandana Remix Fun Pack!

The good folks at Coilhouse were kind enough to release something I’ve been working on for a bit: The DIY Guy Fawkes Bandana Remix Fun Pack Genuine Revolutionary Occupy Experience Machine!

The general idea is that I’d like people to be anonymous, wearing protection, projecting a captivating image, employing creative disruption, and in possession of crucial data whether protesting or no. I also believe in opening up the source as much as humanly possible/ethical/feasible on all of my projects.

However, I was worried that releasing a full source would diminish the value of the initial product to the people who have been buying them to support both protesters in the street and myself as a business. I’ve also been afraid (based on some laughably earnest emails) of people looking to copy my design for profit.

I felt like giving people a Creative Commons pack full of resources, info, and stencils might be the right tack to getting anyone an OWS bandana regardless of finances without pissing off the folks who have so graciously bought bandanas and haven’t yet come to burn my house due to late shipments.

Hopefully I’ll have a chance sometime soon to cut out some stencils and provide a tutorial on how to make your very own bleach printed OWS bandana. I designed the stencil to minimize the cutting without sacrificing the design or readability. Since there’s a PDF version, converting things for laser cutting is a snap, and I’m fairly convinced this wouldn’t do poorly as a spray painted symbol as well.

Hackerspace Stamps do my Heart Good

Look at this. The folks from Dangerous Prototypes are totally rolling with the Hackerspace Passport train. It’s beautiful watching the stamp design progress on their forum. Their design features a check box for the continent where the visa was applied and a line for the location and notary’s signature.

This is exactly the kind of innovation and mutation I was hoping for when I released the Hackerspace Passport Remix Fun Pack. I’ve got a feeling that there will soon be a pile of mutant passports on the way. I, myself have some plans in the mix for passports with printed paper circuits integrated into the design.

Downloadable Source for Hackerspace Passports

People have been asking for a more customizeable version of the Hackerspace Passports as a launching point for their own projects. I’ve made a kit packed with the illustrations I made for the passports, psd’s for all the patterns, stamp designs for the hackerspaces used in the passports, and the original InDesign file. This should be everything you need to build your own customized slice of awesomeness.

Everything’s released under a Creative Commons Attribution NonCom license, so remix to your heart’s desire. As long as you aren’t selling off the elements or removing the credits or something reprehensible like that you’re free to make ’em, remix ’em, distribute ’em, download ’em, share ’em, and make the world a better place with the collaborative magic that happens because of ’em.

Resume Rekindled. Portfolio Polished.

This is the man who would, ostensibly, be working for you.

It’s been a year since I tended and reviewed my whole resume/portfolio package. Recently, I’ve had enough freelance and word-of-mouth work that it hasn’t mattered much. Still, I’m still eager for that big dream job – that flexible, profitable, secure, and above all challenging career that will fill my best years with purpose and a string of successes.

So, in that spirit, I’ve primped and preened the best of my work into a little portfolio for the world to see. If you happen to be in the market for a go-anywhere do-anything obsessively focused designer who’s equally comfortable in the metal shop as the computer lab, you might want to take a look at my resume as well.
