Hello, mortals! Perhaps you saw me at Maker Faire NY over the weekend; I was the orange dude with the screen head taking your picture with my face. Well not only did your souls add a few thousand years to my already infinitely long lifespan, they got uploaded to the internet, where myself and others can browse them at our leisure from the comfort of our own time traveling spaceships. Have a look yourselves, and I’ll see you all in the past (or in the future, from your puny human perspectives).
We have an open call for Summer 2014 Fellowships at Advanced Manufacturing Research Institute (AMRI), hosted at Rice University in the department of Bioengineering.
We are soliciting applications for the following projects:
Project 1: e-NABLE 3D Printed Prosthetic Devices
In collaboration with the worldwide e-NABLE group, and Gloria Gogola, M.D. at Shriners Hospital for Children, Fellows will aid in the design, 3D printing, testing, and refinement of open-source prosthetic hand and finger designs. This unique fellowship will bring 3D printing into the clinical setting, working closely with Dr. Gogola and her patients in need.
Project 2: Selective Laser Sintering (SLS)
Fellows will augment and refine the open SLS design pioneered by Andreas Bastian last year. SLS machines typically cost $50k or more, we built ours for under $15k. This year we will focus on powder manufacturing and powder handling, as well as characterization of SLS parts via scanning electron microscopy (SEM) and mechanical testing.
Project 3: OLED 3D Photolithography of Living Tissues
Related to Anderson Ta’s exciting digital light projection (DLP) photolithography last year, Fellows will investigate and program organic light emitting diode (OLED) screens as a light source for 3D photolithographic printing of living tissues. Chemical functionalization of glass surfaces will also be investigated to passivate the screen surface and aid in detachment and 3D printing from the light source surface.
Project 4: Open Source Ink Jet Printing of Bacteria
A continuation of Steve Kelly’s inkshield augmentation of RepRap motherboards to print living bacteria, Fellows will investigate fluid mechanics, python scripting, and multicolor printing to create interacting bacterial colonies on top of and within agar gels. Fellows will also learn how to insert genes of interest into bacterial colonies for protein production. Steve’s 2013 AMRI Presentation is available here.
Check out all the details, and be sure to apply by May 15th:
Questions can be directed to firstname.lastname@example.org.
When I saw this poster on the right in the lobby of our studio building I thought it looked neat, but it wasn’t until the mastermind Dave Kyu visited that Hive76 was convinced to participate in WriteSky. Well, he mostly convinced me, as I ended up as the only contributor, but I am glad that Hive76 was able to host the collaboration meeting with our fellow group, artists that work in 319 N 11th St, members of Grizzly Grizzly and Tiger Strikes Asteroid.
We met on one Wednesday open house to figure out exactly what message we would write over our neighborhood. I don’t have a lot of history collaborating with other artists, but after the experience I had using Dave’s process and the smart 319 Artists Mary Smull, Jacque Liu, Sarah Kate Burgess, and Jaime Alvarez, I am looking forward to my next collaboration. It was a pleasure brainstorming, discussing, and compromising to come up with what we think is the perfect sentiment to be written in the sky for a few minutes. What message is that?Ah, but ours and the two other collaborative groups’ messages are secret up until the actual writing. We want it to be a surprise.
If you can make it this Saturday, please come to The Eraserhood at 11:30am and look up. Weather permitting, you’ll see three wonderful messages written in vaporized canola oil over the Philadelphia skyline. It will be visible for about 15 miles, but the best view will be directly underneath. If you see the writing in the sky, tag it with #WriteSky and it will appear on the page: http://writesky.com/photos/
Keep looking up!
Our friends over at The Hacktory (Repurposing Technology, Making Art) are running a Kickstarter to raise matching funds for an excellent project to unite artists with the latest technology to empower new designs. From their Kickstarter page:
Electronics and digital technology can infuse works of art with an element of magic. At The Hacktory we have literally put this magic in people’s hands, through classes and large public events. We want to do more though. We want to make our classes available to artists. We’ve found that they are usually the most excited to take our classes and play with technology, but usually the least able to pay for our classes.
The Hacktory is creating a program called T.E.R.A. Incognita: Tech Education and Residency for Artists. Our goal is to support artists who want to create new work and experiment with technology such as cameras, projectors, sensors, robots, software and circuits. The name “T.E.R.A Incognita” is part acronym, part vision for the program. We want to give these artists an opportunity to learn and explore at the edges of technology and art, literally in unchartered territory, to create new experiences and new possibilities with code, hardware and creative expression.
The Kickstarter ends on Monday, so go check it out and consider making a pledge! Some great rewards are being offered too.
Three more things in my house require a remote control now, and one of them is the streetlight in front of my house. Ever since I heard about a hacked streetlight at the Guerrilla Drive in for Back to the Future in 2009, I have been turning off the streetlight on Darien Street by carefully aiming a laser dot at the light sensor on top of the streetlight. The light sensors on most streetlights face west to catch the last photons from the fading sunset before illuminating for the night—and this one faces right into the third floor of my house. It is very important to me to be able to choose to sit in the cozy dark, save my city some money, and not contribute to light pollution for a minute.
Just recently I revamped the process with a new, permanent laser and remote control system. Here it is in action:
I’ll show you how …
“Hey let’s take the boat out.”
“Hold on, I wanna build a hydrophone first.”
And so, using the parts left over from the day’s Piezo Transducer Class, some wire, a spraypaint cap, red solo cup, and two sticks, the Hive76 Aquaphone was born. With a battery powered amplifer and some groovy headphones, we had ourselves a mobile underwater listening apparatus. Globs and globs of hot glue waterproofed all connections. (more…)
This past weekend I had the great pleasure of competing at NERC‘s Motorama Robot Conflict with my fighting robot Such and Such – built 100% at Hive76.
Though it might have looked a little boring, that was the most exciting match of the competition for me. After 2 years of on-and-off work, Such and Such, the most ambitious robot I’ll ever build, worked like a charm.
The Creator’s Project released a new video, and our sugar printing, gelation, and blood pumping was featured in it! Trackback is to 3Ders.org The project goal is to unify artists and technologists and this video is focused on 3D Printing:
And I just got done with a talk at ScienceOnTap Philly! It was a truly excellent night! Special thanks to the Organizers and also the Hivers who came out or emailed in their support! You peeps are the best.
Here are some pics via the Twittersphere. Thanks to the photographers for posting!
This year I wanted to do something a little different for Christmas gifts. Instead of just getting people electronics or video games or clothes, I wanted to give something that encouraged creativity and making. A lot of people never even think to try to make things on their own, so maybe a little hobby-style gift will give them a taste and spark an interest.
To that end, I did two things. First, I bought ten MSP430 LaunchPads. These things are really inexpensive, so they make great stocking-stuffers. If you don’t know what the MSP430 is already (really, we talk about it constantly, where have you been), it’s a 16-bit microcontroller with really low-power consumption needs. They run on 1.8 to 3.6v power supplies at up to 16MHz, making them quite a powerful little beast for only $4.30, which includes the chip programmer. If you were to buy the chips alone, they cost about $0.50 each, with a few different serial communication protocols built in, and requiring only a small selection of external parts (2 resistors and 2 caps if you want to do it right, 1 resistor if you’re living dangerously, and face it, at $0.50, you can afford to live dangerously). It’s something of a long-term project plan of mine to buy 100 of these and try to build a small, physical neural network computer.
A lot of people have shied away from the MSP430 because the Code Composer Studio software–based on the professional-grade Eclipse development environment–is very difficult to use in comparison to the Processing-based software typically used to program Arduinos. But luckily, someone has taken the Arduino cue and created Energia, a Processing-based editor for use with TI’s LaunchPad line of MCUs! If you’re experienced with Arduino, using Energia is a snap, and if you’re not experienced at all, it’s really not that big of a learning curve.
Second, I bought supplies to make “magnetic Silly Putty”. About a week ago, I saw this Instructable about kneading some Iron-Oxide powder into a little Silly Putty and jumped on Amazon right away to get a 6-pack of Silly Putty eggs and a 5 lbs bag of black Iron-Oxide pigment. Honstely, 5-lbs is way too much, but there are plenty of other things you can do with it, like make ferrofluids or your own paint, so it’s handy to have around. You will need a fairly strong neodymium magnet, but again, these things are fun enough to have around anyway, so have at it!
Making the putty is really easy. I pooled all 6 eggs of putty together in a non-stick pan. On very low heat, I warmed up the putty until it was just too hot to handle with my bare hands. If it starts to become the consistency of chewing gum and sticks to the pan, don’t worry, it will unstick when it cools down. Don’t heat it further than that though, it will start to smoke and burn. Wearing rubber gloves to give me just enough insulation from the heat and to keep my hands from getting stained black, it’s just a matter of working a large, heaping tablespoon-full of the black powder into the putty. You will need to work the putty like taffy, stretching it and folding it to blend the powder evenly into it. Once the powder is sufficiently kneaded in to the putty, it will not stain anything, so keep testing it on the back of your rubber glove to see if it leaves any marks. I then cut the putty into 6 equal chunks and shoved them back in their eggs. It took 10 minutes total. I thought about taking some photos of the process to show it off, but really, it could not be simpler.
I’m hoping these gifts will be completely unexpected and will inspire people to try something they never would have considered on their own. The MSP430s are just a really easy, cheap, fun way to get into programming, and the magnetic Silly Putty is a great example of something you can’t buy as a product that is also extremely easy to make.
Lately, a few members have been discussing the use of 3D printed parts in use with metal casting techniques to create some stronger, lighter and more durable parts. As all good hackerspace conversations do, we immediately decided to go with the most painful and difficult solution: Metal Casting. Luckily for us the very next day, we got an e-mail that a local group, Philadelphia Sculpture Gym, that they intended on hosting an aluminium greensand casting class. A perfect opportunity to learn some metal casting techniques, even if not totally applicable to what we wanted to ultimately end up casting. Andrew S., and myself both signed up along with a few friends of Hive76.
About 30 minutes into making our own greensand molds, we realized that this was going to be a difficult process, and immediately destroyed several hours of work trying to get a good crisp mold for our first pour.
Several hours into our class, we managed to finally get a good solid mold of a 3D printed TARDIS. We hopped in line and got a pretty good looking cast. Andrew also attempted the TARDIS with some success. He also managed to get some good casts of a wooden puzzle, including one that blew out. However, due to our earlier troubles, we decided to hedge our bets and get one more good pour out of the class before we would start wrapping up. While waiting to pour ours, I was being shown how to work the furnace by Gus, and ended up melting down plenty of scrap and helping others make their pours which was a lot of fun to be working with. The furnace was operating at about 1300 Celsius, and moving around molten metal at that temperature can be quite a thrill. We plan on working with Gus and Darla at Philadelphia Sculpture Gym on some other types of casting techniques, especially as they apply to our 3D printing. We look forward to working with them in the future, and hope you all consider taking their next Greensand class in January.
