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:

There may not be time to print everyone’s design, but you should go home with something 3D printed.

Fighting Robot Night at Hive76!

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!).

In the meantime, here’s some old Battlebots videos to get you excited.

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.

 

I just got back from the 2012 Open Science Summit which took place in Mountain View, CA. It was an excellent meeting and a great opportunity to meet others using open tools and ideas to forward Science! Check out the list of talks and you can also access videos of all of the talks. And you can also read more about the speakers.

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.

 

We are cosponsoring Cory’s Pirate Cinema event at IndyHall tonight, but since there’s not much for Hive76 to do, we decided to make him a present. Here’s a video of production last night:

That’s a 3D printed sugar head! Cory’s excited to see it in person. You should be too! Come to IndyHall 22N 3rd at 7pm tonight. Here’s the Anyvite link to RSVP. We’ll be bringing a boomcase for the PA too.

The gritty details: That’s a Baricuda extruder using air pressure to extrude molten sugar. Now I need to figure out how he can get it home to the UK in one piece.

Hive76 @ Maker Faire NYC 2012

Hive76 sure made the rounds at this year’s Maker Faire. With 2 tables in the 3D Printing Village, we had a steady stream of visitors both

eagleApex being interviewed

days, ranging from Chocolateers, Digital Artists, to young children asking about 3D printing toys and parts for their projects. Discussion started about 10 minutes after we left Maker Faire for what to do next year. Check out the album for some quick snapshots of this year’s events including Karaoke, Thumb Wrestling, and of course, the occasional interview.

 

At Makerfaire in NYC this Saturday, Hive76 will be running a race to test the quality and speed of any 3D printers that would like to participate.

We will have an announcement and official start in the 3D Printer village at noon on Saturday. But the basic premise is this:

  • We will announce and post a 3D model on this page.
  • Racers will download and print the model in any material
  • The model will need to fit on a metal part and hold water
  • The first part to hold water without leaking for 5 minutes wins!
  • The prizes: a Math Watch by eagleApex (me) and a file to print your own trophy!
In summary, printing an accurate, water–tight part quickly will be a good balance of those three 3D printing goals.

Besides this 3D printer vs Man race, I think this is the first race of it’s kind! I hope you participate and I’ll see you there.

Update:

Here’s the file for the race!

Hive76′s own PJ Santoro will be doing the “Main Presentation” at

the Philadelphia Area Computer Society‘s kickoff meeting, Saturday,

September 15th.

His topic will be “Arduino: Where It’s Been, Where It’s Headed, and Why You Should Care”.

After the main presentation, a beginner class will be taught in the Linux SIG.

PACS Schedule available here.

 

Rob Bishop, a developer with the Raspberry Pi Foundation, is going to be taking a short tour of US hackerspaces. We are pleased to announce that Hive76 has been included on that list!

Because we are expecting a very high level of interest in this event, we have decided that our studio space is a little too small to accomodate the number of people we are expecting to attend. Philadelphia’s University of the Arts has  graciously offered up some space for us to meet in. There are only 30 spots available, so act fast; this will sell out. Ticket purchased are limited to 2 per person. You’ll find the link below.

If you’ve been wanting to get a taste of the Raspberry Pi (:P), you will not want to miss this event. The event is free to the public, but space is limited! Rob will have Pi(s) for sale at $35 per board. They are still on back-order from major  distributors, so now is your chance to grab one!

Here is what to expect:

Rob Bishop from the RaspberryPi Foundation is touring popular hackspaces in the US throughout September 2012 with the aim of giving talks and workshops about the RaspberryPi to both the hackspace members and also RaspberryPi users in the local community.

The Raspberry Pi Foundation is a charitable organisation founded with the aim of promoting the study of computer science and related topics, especially at school level. The Foundation is responsible for the design and sales of the popular RaspberryPi single-board computer. You can find out more about the Foundation and the RaspberryPi here.

The event at each hackspace will informally consist of the following;

  • Talk:
    • RaspberryPi: Past, Present & Future – An introduction to the RaspberryPi, including an overview of its history and development, details on the technical specification and an outline of future developments with many cool tech demos along the way. Followed by a Q&A session.
  • Tech Demos:
    • A chance to demonstrate various OS’s and other demos
  • Workshop:
    •  A chance to play with the RaspberryPi hands-on.
  • Show & Tell / Prizes: 
    • An opportunity to display RaspberryPi projects from the community with prizes for notable projects.

The tour will be blogged/vlogged on the RaspberryPi website and we hope to attract RaspberryPi enthusiasts and hackers/makers from across the areas we will be visiting, allowing us to meet and support our community.

Here are the details on where we are meeting and at what time:

University of the Arts, Terra Hall, 5th floor

211 S. Broad Street, Philadelphia, PA 19102

Monday, September 24th, 7:00PM-10:00PM

 

Update: Corrected UArts address
