[Editor note: This is a guest post by the wonderful Chris Young. He's making his own 3D short film from the ground up. -eagleapex]
My goal was to make OpenDCP work on a Sony SRX R-320 and after numerous attempts — as an independent filmmaker, I am elated to say it worked perfectly! It wouldn’t have been possible if Terrence Meiczinger hadn’t developed OpenDCP.
Admittedly, a few weeks ago I didn’t know much, if anything, about creating DCP files… let alone a stereoscopic 3D-DCP. I had recently finished work on a self produced and directed short film, “Dead of Nowhere”, that I was able to make largely in part utilizing the crowd-based funding site Indiegogo. I used a Final Cut Pro / 2K Cineform workflow to edit and finish my film. I shot my film guerilla style in one day, handheld on location with the Element Technica Dark-Country beamsplitter rig, recording to a 1-Beyond Wrangler. When I learned that it was going to cost somewhere between $1,500 and $3,000 to have my ten minute film encoded in order to have it shown in a realD™ equipped theater, I knew I had to find an alternate “indie” solution to create my DCP.
While the notion of using an open-source command-line tool, still in development, isn’t for the faint of heart, and I am by no means a Unix Pro, the process was pretty simple once I understood how the OpenDCP tools worked.
There have been plenty of how-to posts, so I won’t get into a lot of detail here… but basically after getting my film into a Left Eye / Right Eye TIFF sequence at the correct aspect ratio (1998 x 1080), the frame rate at (24p), ensuring that my audio was the exact same length (intrinsic value) and the correct sample rate (24bit), it was a fairly straight forward process to convert to XYZ jpeg2000 (.j2c) using opendcp_j2k and then using opendcp_mxf to wrap the stereoscopic-picture and main-audio elements into separate mxf files. After figuring out that I needed to be sure to have the digest (-d) and annotation (-a) tags set in opendcp_xml, it was then just a simple matter of getting these files onto a drive to load into a cinema server.
Now, don’t get me wrong, this will probably not work the first time. I had to make several trips back and forth to the theater, trying various DCP versions (interop and smpte) and hard drive formats (I settled on NTFS).
If you’re an indie-filmmaker, trying to get your film digitally packaged for exhibition and don’t have the money to spend, or are the kind of person (like me) that enjoys learning about every step of the process — I couldn’t recommend a better, more rewarding way of creating a DCP.

We are proud, tonight, to continue this tradition. We would like to congratulate long time Hive76 member Adam Kaufman, also know as Adam on IRC, for joining the ranks of our elite.
Take a bow Adam. You’ve earned it.
As rumors of delicio.us shutdown rumbled through the internet, a bunch of geeks in a minor IRC channel started gabbing. They has a lot of info, links, tags, and data stored in delico.us, and were afraid to lose them, syncing, and all other good features. They realized as geeks often do, that if we owned the service, we wouldn’t have to worry about outside shutdowns if we had our own service. Thus hypatia spun-up Federated Bookmarks
The first output of this crew is something called gitmarks, based on work by Hillary Mason (of bit.ly). This is a little tool to store bookmarks, bookmark metadata, and page content locally for searching, using, and peer-to-peer sharing. Since it is based on git this system can use a central server, *or* it can share peer to peer. As the name implies, it uses a git backed for data transfer and versioning. It also has the ability to pull down content for a local cache, and for local searching.
This project is in Alpha, and if you want to test the silly thing, the basics work. If you want to help build a cool distributed tool, we could use some help! We need to building a server, building more git tools, xmmp messaging, and browser integration. We also hope to create tools that along the way that make it easy to build systems for Moglen Boxen.

Back in 2009, we ordered our first 3D printer, the MakerBot Cupcake. Since then, we’ve become pros at fixing, modifying, and mostly breaking it. We’ve even created new, awesome products for it which have been adopted by a good portion of the 3D printing community, and even sold by MakerBot themselves.
Shortly after completing our Makerbot, once-member fynflood decided to start building the RepRap Mendel, which is the 2nd generation of the RepRap Project’s 3D printer. He started by printing all of the pieces on our MakerBot, which took over 20 hours to complete, and gathered all of the required hardware with help from many of our members. A printer was born out of Hive76, and life was good. A few months later, there was a post on the reprap aggregation pipe about a new iteration of the reprap, called the Mendel Mini (now the RepRap Huxley), which has a similar build volume to the MakerBot, but can be assembled for under half the cost. Fynflood set out to print the parts on his Mendel, while I gathered all the required hardware and electronics. After a few months break over the summer, and a few more months being busy with the Holidays, the Huxley is now complete! Our printer’s baby made a baby!
At this very moment, we have 2 MakerBots and the Huxley all going at the same time at the space! If any more printers show up, we’ll probably have to start giving away USB Typewriters just to make room! Really, it’s an exciting time to be printing at Hive76, so if you have any interest in learning how 3D printers work, or even building your own, come by for open house on Wednesdays and check out all the awesome things we’re making!
Hit the jump for a few videos and images from the first few prints!
This is a busy weekend for Hive76, with classes and guest speakers and projects out the whazoo, so if you can manage to dig your way out of your snowy sarcophagus, come on down and see what’s happening.
- Friday, Jan 28th – At 6pm tonight, we’re having a new member orientation meeting. This will be one of the first times we’ve had so many new people join at one time to warrant a specific “orientation”. This event is open to new members as well as any old ones who would like to get more involved at the space. Afterwards, we are going out to a nearby restaurant for dinner and drinks.
- Saturday, Jan 29th – From 10am to 4pm we are running our “Making Things Blink and Buzz” class ($40, kit materials included) with Far McKon. This class is a hands-on workshop for building fun noisemakers without getting bogged down in drawn-out mathematics and electronics theory. A couple of seats still remain open and we do take last-minute entries if you are paying cash-at-the-door.
- Sunday, Jan 30th – From 5PM to 8PM we are running a special open house for analog audio hacking. This is an open house for anyone of any skill level to mess with audio electronics. The event is free, you may bring your own materials, or beginner audio kits ($15 – $30) are available to get you started. A few very knowledgeable geeks—Jimmie P. Rogers, circuitbender and designer of a popular Atari Punk Console kit, and our very own Brendan Schrader, cohost of our Guitar Effects Class—are on hand to help out with more advanced projects.
This is just the start to our new year of classes and workshops. We have a few exciting events currently in planning stages, including a workshop on Rapid Prototyping and a series of workshops on Mixed Drinks and Molecular Gastronomy. Also, don’t forget our weekly open houses, every Wednesday at 8pm, where you can meet our current members, get to know everyone, and join our ranks yourself. Members get discounts on classes and kits!
(ed: snafu on list of attending “experts” fixed)
Hive76 really wants to make one! So we have adjusted the pledgie where we are collecting donations to match the new goal: $2000. Here’s the cost breakdown:
- $570 Lasersaur Alpha kit: optics, electronics, belts, fasteners
- $500 Extruded aluminum rails
- $700 Fume extractor for exhaust
- Remaining funds for unseen costs
- Free: Laser tube from Meatcards, Stepper motors from Meatcards or elsewhere, Paneling is nominal.
You can read more about the original entry HERE.
We’ll be using the Ponoko gift certificate to design a housing for the electronics and make it more kit-able. Bench Science FTW!
“We’d like to create a magazine for the scientist in all of us.
It will have simple How-To’s, like extracting the DNA of a strawberry using kitchen materials. But on the next page could have a paper on the validity of using Bacillus Subtillus as a model organism. We’d feature extraordinary citizen scientists who are doing extraordinary things in abnormal labs (aka garages, closets, etc). We’d also give legal and safety tips to inform and protect citizen scientists from some of the dangers they could run into.”
Here is my entry for the Open Call for Open Science Equipment Contest.
I did this with help from Mike, Jack, Rob, Adam and others right here at Hive76. Thanks everyone!
Details and all source files for this project are available on Thingiverse.
The deadline for submission is December 15th, so if you have an idea for open source equipment you still have some time to submit your entry to the contest!
