Weekend Wrap-Up with a Look Towards the Horizon

If you happened to pass through the door of Suite 519 in the 915 Art Studios building this past weekend, you know what a busy time it was. Things kicked off early Saturday morning with the focused goal to start and finish a new 3D printer build, the MendelMax. A few folks started to filter in after a while: some to lend a hand, some to hang out, and some to work on their own projects. At around 2 PM, more people came in for our hosting of the monthly Philadelphia Star Trek meetup group. Afterwards, Dan was awesome enough to run through an impromptu class on how to develop your own Pong clone using the Unity 3D game engine with some of the Trekkie attendees.

Sunday also got off to an early start with the Ubuntu Bug Jam hosted by Hive76’s own jedijf. Jim was pleasantly surprised to have some Linux newcomers on hand and jumped at the opportunity to teach some command line skillz in a way only he can. In true geek fashion, they were rolling along on IRC by the end of the session! Shortly after the Bug Jam got underway, Jordan and Matthew were back at the MendelMax, determined to have it printing well, and packaged up to be shipped out by the end of the night. On the heels of the Bug Jam was the first installment of the Philadelphia Game Developer Collective which brought such a turnout that we actually ran out of chairs! This meant that our next meeting, the PAFA build group, had to get together in the lobby to hash out some last minute details and designs. While these two groups were meeting, and the MendelMax was being built, Brendan and Robert were plugging away at the hand-built custom control panel that they’ve been working on. It really looks awesome.

Flys like a dream!

Despite all of these things happening at the same time, everything could not have gone better. We were able to introduce some new people to our space, greet a few familiar faces, teach some new technical and mechanical skills, brainstorm new ideas and projects, and get some really great work done! I was pleasantly surprised with all of the spontaneity happening within and around the edges of these groups.

That said, if you missed all the action this past weekend or would like to come back for more, we’ve got some up coming events that you won’t want to miss!

Wednesday, March 7: Our ever popular weekly open house! This is the number one best way to meet the people behind Hive76 as most of our members are here on Wednesday nights. You’ll get a nice tour of the space, exposure to some of the projects that are in the works, and plenty of great conversation! Always FREE!

Thursday, March 8: PAFA After Dark: Turned On! Finally, come out to see the fruits of our labor! Hive76 and the Hacktory have teamed up once again to bring you some awesome interactive installations to play with in between checking out the excellent art of Henry Ossawa Tanner. Tickets are available for $10 (non-PAFA-members) here.

Saturday & Sunday, March 10 & 11: Art Hackathon @ Hive76! Come join Hive76 for an eight hour, two day art hackathon where participants will have a chance to really get creative under a common theme with recycled materials and various art supplies. A fee of $25 is being requested for supplies and food. Email smcbeth_at_hive76.org ASAP to RSVP.

Monday, March 12: Our March installment of MMMM is coming up! If you’ve got a soft spot in your heart for microcontrollers or are eager to learn a thing or two about them, this is the workshop for you! Designed to be beginner friendly, this workshop is open to everyone. This is a FREE event!

Be sure to keep an eye on the Calendar for upcoming events, or better yet… join our discussion list or hop in our IRC channel, #hive76 on freenode and have a chat! Hope to see you soon!

Timelapse: Building a RepRap MendelMax 3D Printer

We got Matt Wettergreen’s MendelMax up and printing in two days. Thanks to all those at Hive76 who helped out with the build, especially Chris, PJ, Brendan, and Rob! Here’s a timelapse from the first day:

Below is a video of the finished bot printing with the latest Marlin firmware (smooth acceleration and fast travel times)! It turns out PLA sticks to a heated aluminum bed provided in the MendelMax kit. Wow. Completely Awesome. I couldn’t believe how little of the heat from the aluminum bed actually radiates away (you can only barely feel the heat an inch off the bed at 75 degrees celsius). That’s a huge feature.

Congrats to the Mike Payson and the MendelMax Team on their inspired Mendel remix. It’s a fantastic RepRap 3D Printer.

Philadelphia Game Developer Collective March Meeting

It’s almost time for the first meeting of the Philadelphia Game Developer Collective. We’ll be discussing our ideas, projects. We will also be looking at the multiplatform game engine Unity.

Join us as we delve into the depths of games!

The meeting starts at 6 PM on March 4th (Sunday).

UPenn Grasp Lab Robotics Demo

The University of Pennsylvania’s General Robotics, Automation, Sensing, and Perception (GRASP) Lab is performing a demonstration of their work on Saturday, March 24, 2012 from 1:00 PM to 5:00 PM (ET) at NextFab Studios, 3711 Market St., Philadelphia. The event is $30 to attend.

I don’t have very many details on what the event is about, but given GRASP’s description on their website that it “…integrates computer science, electrical engineering and mechanical engineering in a vibrant, collaborative environment that fosters interactions between students, research staff and faculty”, it sounds like it could be a very interesting demonstration of some top-of-the-line robotics research projects. From the details on their site, it looks like they do some work with autonomous drones and quadrocopters. Could be really interesting.

My Blade mCP X Mods

She ain't pretty, but she flies great

I’m a noob when it comes to RC helicopters. I got a Syma S107 for about $30 a year or two ago and it is incredibly stable while being ridiculously bulletproof. I can fly it into walls, and I’ve never replaced a part. If it’s laying on its side on the floor, I can often get it to right itself by just gunning the throttle. (Do I recommend it? No. Do I do it? Sometimes.) A wire fatigued off the board once but that was the only thing I’ve had to fix. It’s a hell of a bargain and it’s treated me great, but being so stable and easy to fly, it has some inherent performance limitations. So I decided to step up a few levels.

I heard about the Blade mCP X helicopter, the first “real” helicopter of its size that came stock with 3-axis attitude-holding stabilization electronics. It weighs maybe double what my S107 does but its performance is amazing. It can do inverted flight, flips, all sorts of crazy stuff. That is, when supplied with an appropriately-skilled pilot, which I certainly am not. But I can fly it in my backyard in 30 mph winds, and this little beast can take it — pretty impressive for something that weighs the same as a good quality 9V battery. Being such a noob, I crash constantly, but I can usually patch things up without needing to buy replacement parts. Here is the list of mods I’ve performed on my helo so far, mostly out of necessity:

  • Grommet mod – tightens up the swash, reduces vibration (not my idea). Works great
  • Tail boom from mCP X2 – comes with a more aggressive tail rotor which helps with yaw authority
  • Created a simple tool to speed up resetting the main gear after crashes – just remove the battery and push this drilled-out rod over the gear hub to click it back in place, no need to remove the canopy or landing gear. I keep it zip-tied to my transmitter since I crash a lot 🙂
  • Lengthened tail boom – added perhaps 1/2″, seems to help with yaw authority
  • Added magnetic breakaway tail boom mount – after a crash the tail boom pops off instead of breaking, can be reset by simply moving it back in place and letting the magnets lock it down. Works very well, but be careful because if you have too much slack then with the right kind of crash the tail motor wires can get wrapped around the head. I’m sure I’ll keep experimenting with this one
  • Masking tape holding my canopy together? Classy
  • Hot glue holding my landing gear together? Not perfect by any means, but it keeps me flying until I buy a spare
Aluminum piece presses into the helo frame like a stock tail boom, but has an embedded magnet. Tail boom is hot-glued to a piece of bamboo skewer that fits into the channel, and has a magnet glued to it using CA and baking soda. Rubberbands or o-rings might be better

Event: Art Hackathon @ Hive76, March 10th and 11th, 2012

Hive76’s Art Hackathon

March 10th and 11th, 3pm to 7pm

For the second weekend in March, Hive76 is hosting a day of smashing, cutting, gluing, taping, painting, and general making and frivolity. We’re calling it “Art Hackathon”. Inspired by the Bravo TV Series Work of Art, and following closely in the footsteps of Art Hack Day, the event will focus on the rapid creation of meaningful works of art out of a provided supply of recycled materials.

Hive76 will provide massive piles of cardboard, tubs of glue, masking tape, tubs of spackle, box cutter blades, and a few cans of various colors of spray paint, to let every participating individual or team create a work of their choosing. The works will be based on a single theme, to be announced at the beginning of the event.

The event is split across two, four-hour days. While participants are free to use the time as they wish, the time is designed to provide time for planning on and a moderate amount of building on the first day, with some drying and curing time overnight before finishing up the next day.

A fee of $25 per person will be charged at the door, to cover the cost of materials and food that will be provided during the event for both days. Please RSVP for the event before March 6th by emailing smcbeth@hive76.org.
