Super-wide screen made from a single large sheet of bacterial cellulose “paper”
PJ and a number of other Hive members have been fortunate enough to participate in preparations for the Drexel Design Futures Lab “Projects 12/13” exhibition. PJ was almost certainly the most involved Hive contributor — he helped with the development of a number of key software elements for several of the exhibits.
Side view of a BC culture, showing the cellulose pellicle (white “gel” on surface), growth medium and some bacteria/yeast colonies (dark brown structures). The bubbles are CO2 produced by the yeast.
I wound up getting involved in the creation of a special display screen that was part of an interactive piece which allows people to “play” with a computer model of bacterial swarms. This piece was part of Tashia Tucker’s exhibit, and she wanted an “organic looking” display surface. After some brainstorming that included condemnations of the high price of silicone etc., PJ suggested bacterial cellulose. What!? The idea of a movie screen made by real bacteria to show movies of simulated bacteria was too “meta” to pass up.
I had grown some fairly large sheets of bacterial cellulose in the past, and was interested in having an excuse to grow something even larger — so sign me up! Tashia wanted a sheet that started out about 4′x8′ so that the final screen could be cropped to dimensions that were about the size of a slightly gigantic person.
Yikes — this was literally a tall order. Bacterial Cellulose (BC) is created by the same organisms that are used to ferment Kombucha — in fact, the “Shroom” or “Scoby” in a Kombucha culture is a big lump of cellulose. So this was simple, in principle, but the scale of the piece left a lot of novel details that had to be worked out.
This Thursday, please join us at a FREE exhibition of the work of Cornelius Varley (1800-1860) put on by the venerable American Philosophical Society. It is a fantastic exploration of the life work of this fellow tinkerer and inventor who’s insight and explorations reminds me a lot of our Hive76 members!
A few of us will also be presenting at this event! We will have live 3D sugar glass printing, exhibitions of Brendan’s boom cases, Dan’s 8 mm RockBox, PJ’s electronics, Corrie’s textiles and artwork, Chris Terrell’s wood burning, and maybe a few more things.
We hope to see you there! Deets and directions below.
On Thursday April 25, our series of events for Philly Tech Week continues as we open our doors for DIY Music Night (5pm-???). If you’re into music, making music, or making things that make music, you won’t want to miss it! If you’ve been to the space before, you’ll know that we run on a steady diet of tunes. And on Thursday, we’ll have all our audio and music-centric projects out in what is sure to be the loudest night of PTW. Come by and see the space, make some amplified noise, hang out, or share your own projects.
We’ll have guitars, amps, synthesizers, sequencers, speakers, fuzzboxes, tremolo pedals, signal generators, oscillators, speakers, drum machines, pickups, karaoke machines and probably alot more – all made at Hive76.
Plus we’ll have a handful of contact microphones to give away! We’ll help you turn anything into an amplified electric instrument in 10 minutes flat.
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.—

***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)***
Our grand finale/blowout/party for Philly Tech Week will take place on Saturday, April 27. Everything from the previous week’s events will be on interactive display, and more. It’s an all-day exhibition of everything that goes on at Hive76 and everybody’s invited!
For Philly Tech Week, I will be showing visitors how to take a shape from Adobe Illustrator into the popular open source CAD program OpenSCAD and make a 3D model suitable for 3D printing.
Draw in Illustrator, extruded in OpenSCAD
I’m sure you know Illustrator. It’s the most successful vector drawing program <clarkson>in the world.</clarkson> OpenSCAD is less well known. It is best described as coding for objects. You make a solid with the function cube() and cut a cylinder() out of it with the difference() function, etc. But sometimes you want a more organic or complicated shape to start with. That’s where artist JK Keller stepped in and made a script that automates some of the process for you. What you need for this workshop:
On Tuesday April 23, Hive76 will be hosting Fighting Robot Night as part of our week-long celebration of Philly Tech Week. We will have four miniature remote-controlled robots designed to battle one another in a table-top arena. All are welcome and all are invited!
Show up Tuesday and sign up for a spot to drive and fight, or just hang out and watch the destruction. Ask questions, check out our space and get your robot rocks off. This will also be a preview of an upcoming fighting robot class to be offered at Hive in which participants will build machines similar to those featured at Fighting Robot Night (TBA, check back soon!).
Hey everyone, as you may know, Philly Tech Week is coming up in late April. Hive76, as always likes to make ourselves as available possible during the week, and offer as much as we can. We’ll be open from 5pm-10pm Mon-Thur, and Noon-10pm on Saturday while showing off one unique and interesting aspect of what we do each day.Update: There’s no registration required for these events.
Monday: 3D Printer / OpenSCAD modeling class where we help people model ideas with OpenSCAD and Illustrator, and then allow them to print it on our 3D printer.
Tuesday: Combat Robotics Demo: Duke it out with miniature R/C machines in tabletop matches – it’s Robot Wars on a hand-held scale. Choose one from a field of 1-lb robots designed and built by Hive76 to drive and fight in a display of electro-mechanical fisticuffs. Learn the basics of building and strategy, and get a taste of upcoming combat robot classes offered at Hive76.
Wednesday: Open Hack Night, for anyone who wants to come and build, hack, or program. We’ll also have a Microcontoller session for individuals who want to become more familiar.
Thursday: Music Night: Come talk to our best music hackers and learn how to build effect pedals, make anything into a speaker and learn about amplifiers.
Saturday: Hive76 Ultimate Open House and Expo: Hive76 will have everything from the previous week available for display, and to play with.Also available will be Karaoke, Music, Movies, Food and Refreshments.
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.
A simple gear was too difficult
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.
