On Wednesday, April 24, Hive76 will be transforming our typical Wednesday open house into a special Tech Week Open Hack!
Over the years, we’ve managed to accumulate a plethora of electronic detritus, as one might expect from a hackerspace. We’d love to invite you to come to our space and help us clean it put the junk to good use! We’ll have some microcontrollers on hand and several members around to help you along your way. The idea is to split attendees out into workgroups that will concentrate on designing and building objects from parts we have available for you at the space! Wanna throw together a bot that responds to table tapping? How about something that plays like a musical instrument? Dig making LEDs respond to external stimuli? Just wanna learn how some of these things might be possible? Slightly annoyed with how often I ask questions in my posts?
—Please bring a laptop along if you have one available. Some programming experience is a plus, but definitely not necessary.—
Wednesday 4/24 5pm – 10
Gratis and Libre (free)

***ALSO: If you haven’t been to Hive76 and want to see what we’re about, stop by on Monday April 8th for our Monthly Monday Microcontroller Madness (7-10PM) or on any (other) Wednesday night for our weekly open houses (7-11PM)***
The critical shortage of organ donors in our healthcare system is the reason I’m registered to be an organ donor and motivates my research to develop suitable replacement technologies in the field of regenerative medicine. Video below! It was an honor and privilege to take part in TEDxYouth@SanDiego, which brought 400 San Diego high school students together to interact and think deeply about the future. It was incredible to speak with so many students who are truly the Architects of the Future.
Using simple yet illustrative analogies to help non-scientists understand his scientific discovery process, Biomedical Researcher Jordan Miller explains to his young audience how he developed vascular structures through 3-D printing. This exciting research is an important complement to advances medical researchers have made in 3-D printing bioidentical human tissue and organs in the lab. it’s a remarkable prospect for the future of organ transplantation.
Deriving inspiration from a cross section of bread and the sugar structure arcing over his dessert, Dr. Miller describes how he combined his background in regenerative medicine, a passion for the maker movement and reliance on worldwide open sourcing to develop viable 3-D printed vascular systems that he demonstrates actually transporting blood.
Jordan Miller, Ph.D. is a post-doctoral researcher in the Tissue Microfabrication Laboratory at the University of Pennsylvania. Involved with the 3-D maker community since its infancy, Jordan uses a 3-D printer in his work in biomedical research and regenerative medicine and credits open-source collaboration and the maker movement as important contributors to the success of his research.
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!
It’s a vidya game but not! A completely audio-based game, the objective is to use sonar to find the hidden submarine and destroy it with depth charges. But be careful! If you are not close enough to hit the submarine, it will get away and you must hunt it down again.
Got an Arduino Mega2560 on the innards side. Got the joystick and arcade buttons from Ada Fruit! Very nice quality, shipped very quickly, and not too expensive to boot. Box was just a little, prefab wooden deal from a craft store somewhere in the middle of nowhere. And the speakers, I think I pried them out of a few alarm clocks.
I gave a talk too where I delved deeper into the science behind our work with RepRap for research in Regenerative Medicine and I made the case that open source is a philosophy, not a checkbox. Try not to get caught up in semantics of open vs. not-open (e.g. one could try to label Arduino as not an “open” platform since it has proprietary Atmel chips on the board). Instead, try to think of open projects as those in which you see people as collaborators (“open”), not customers (“closed”). We all have many things we can learn from each other, and who doesn’t want more collaborators to learn science together? Some interesting Q&A at the end too.
Modified MendelMax #2 was born today. Isn’t she purty. This bot is gonna live at Hive76 for the forseeable future.
Thanks to all at Hive76 for help and support during this build, especially to Rich and Andy for hanging tough in the trenches, Chris and Brendan for troubleshooting and tools, and Morfin for extra supply bits.
We’ve got big plans for this bot. Stay tuned. And here’s a video of the first print!
anointed Hive76 as the most organized hacker space he’s seen. Quartermaster Brendan took appropriate pride in the observation.
Mitch basically talked about the Maker/Hacker movement in general, showed some of the kits that were keeping him company on the train, and weaved it all in a thematic web reminiscent of Arlo Guthrie’s is-this-guy-rambling-no-holy-shit-he’s-a-genius-because-it-all-makes-sense-in-the-end style.
After that, everyone bought a kit or two and lost themselves in the task of soldering. I don’t know whether it’s the solder fumes or just the act of soldering itself, but I felt pretty good at the end of it all.
The new space is completely awesome and turned out to be nearly perfect for the event. Hats off to Brendan, Robert, PJ and Jordan!
One of our core members, Jordan Miller, has just published a scientific paper using RepRap 3D printing technology to engineer living tissues for regenerative medicine. I’ll give you a rundown of the science and a step-by-step guide of how Jordan got to this great spot in his career. Jordan is quick to point out that this is work that would not have been possible 5 years ago, or without the help of RepRap, Hive76, and this wonderful city of Philadelphia.
There are other labs around the world that are attempting what Jordan and the rest of the team at UPenn and MIT have been working towards. The end goal of regenerative medicine research is engineered tissues and replacement organs for treatment of human disease. As Science news says,
Imagine a world where if your heart or kidneys failed, you wouldn’t have to endure an agonizing, possibly futile wait for a donor whose organ your body might reject. Instead, a doctor would simply take cells from your own body and use them to “grow” you a new organ.
Other lines of research are attempting to 3D print directly with living cells and gel. These so-called “bioprinting” approaches involve loading cells and gel in syringes to be used as feedstock to create a structure from scratch. The problem is that healthy liver cells, for example, usually die of starvation (lack of nutrients) and suffocation (lack of oxygen) while enduring the slow 3D printing process.
Jordan’s 3D printed vasculature approach was inspired by whole organ vascular casts like this one.
Enter Jordan and his innovation: since vasculature provides the lifeblood to resident cells, why not focus on the vasculature first?
Jordan and the rest of the research team at UPenn and MIT have developed a new way to create vasculature for living tissues. This 4 step process involves: 1) 3D printing a network of sugar filaments, 2) surrounding it with living cells in a gel, 3) dissolving away the sugar to leave behind a vascular network for 4) the delivery of nutrients and oxygen. He accomplished this with a custom built 3D printer, extruder and control software.
Here’s a step-by-step of Jordan’s many year process:
Get a crazy idea to link sugar and vasculature when comparing the interior of a 3D print to a capillary network.
You can read the Penn press release about this awesome science, an overview from Science News, or the full paper. A more detailed post about the hardware used in this project will follow and soon you’ll be able to make your own sugar extruder. (It prints chocolate too!)
