GE Garage And Chicago Ideas Week

October 12, 2013 by 4 Comments

I’ve been on vacation and managed to get a day to play at the GE Garage mobile fab lab currently setup in downtown Chicago. GE has partnered with Chicago Ideas Week to bring the future of fabrication technologies to a space where the community can walk in off the street and work with some amazing hardware like CNC mills, laser cutters and 3D printers. The group is also giving classes at select times on using the equipment and general electrics. Unfortunately I was in town near the end of this event which will be Oct 20th. If you are in the area I do recommend jumping on the excellent transportation you’ll find in Chicago and have some fun at the space. Here are more details on location, classes and times.

I didn’t expect to squeeze any work into my vacation but I did take a guided tour of the fab space with my iPhone 5s.  You can join me after the break to watch the tour, which is a bit rough but still covers a lot of fun topics. Get at look at their line-up or Replicator 2 3D printers. See some fantastic prints from metal made on industrial scale printers. Learn more about the up-scaled CNC seen above that was cutting out skateboard decks. And finish up with an injection molding machine.

European Hackerspace Tour

October 12, 2013 by 48 Comments

Eurotrip

Wow! What a response we received on our Calling European Hackerspaces post! First off, thank you for such a warm welcoming to your hackerspaces. It looks like HaD is going to have to be way more active in touring and profiling hackerspaces!

Now unfortunately we’re just not going to have time to visit all of the ones suggested, but we’ve outlined a few of the ones we definitely want to check out!

We created a Google spreadsheet to help do this, so if your hackerspace has been mentioned, OR if it happens to be very close to the others and you really want us to come, please fill out some contact info on the spreadsheet so we can setup a time to visit! If you don’t want to put contact info in a shared document, send an email to the tips line instead with the subject [European Hackerspace Tour]. Because its unlikely our trip will coincide with any open nights, we’d love (need) to have someone to show us the space at potentially odd hours!

I will be writing an individual post for each hackerspace tour with lots of photos and details on all the juicy projects you guys are working on. And if we have time, we might even film the tour!

Once again, thank you for the amazing response and we can’t wait to meet all of you in person!

SSTV Beacon Based On A Raspberry Pi

October 6, 2013 by 17 Comments

The Budapest hackerspace did some joint work with a local ham radio club and created an SSTV beacon housed inside a CCTV case that takes an image of its environment and transmits it using slow-scan television over ham bands.

As the title says, the build uses a Raspberry Pi to process the image taken from its camera and then transmits it over the air using a Ricofunk UHF transceiver with a main frequency of 433.425MHz. On the software side, PySSTV is used to convert images to frequency/time tuples, UNIXSSTV then creates the actual audio file and finally sox plays it. To avoid screwing up the Raspberry SD card, every part of the filsystem is either mounted in read-only mode (things like /home and /usr) or uses a ramdisk (things like /tmp and logs).

The plans, schematics and source code are available, so they hope that other hackerspaces will join the ranks!

How This Power Racing Series Car Got On A Plane To WMF

You really should check out the monthly meetings at your local hackerspace. It’s an excellent opportunity to hear the most interesting stories. Like the tale of how the guys from Sector67 got this electric vehicle on the plane with them. Not only did it go up in the air, but they did zero planning ahead of time on how they would actually pull it off.

[Bob Baddeley] posted an album of the PRC experience at World Maker Faire. There are captions that somewhat tell the tale, but we’ll fill you in as best we can on the rest of the story behind this second car from the hackerspace — lovingly known as the Lamebourghini.

Calling European Hackerspaces!

In a few weeks time, I will be in Düsseldorf on business for the world’s largest plastics and rubber industry trade show, the K-Show. That’s not very interesting for you, but afterwards a coworker and I will be traveling for a week in Europe, and being the geeks we are, we would rather visit you instead of the typical tourist attractions (mind you I have lived in Germany for half a year).

The majority of our Hackerspace Intro pieces thus far have been limited to North America, so we would love to visit your Hackerspace in Europe! Take pictures, ask a few questions, get a tour, and share it all here!

If you are part of, or know of a cool hackerspace in approximately the geographical doodle shown on Google Maps above, let us know in the comments! We will be traveling around October 19th to the 24th.

Project Thumper Walkthrough

The Geek Group is at it again! Many years ago they built Project Thumper, a 1,600V @80,000A electrical impulse … well … “thumper”.

For those of you that don’t know, The Geek Group is the world’s largest not-for-profit Hackerspace. Lately they have been working on developing better videos for their YouTube channel, and have just released a stunning CGI animation of the build, operation, and explanation of Project Thumper.

So what is Project Thumper? In the simplest terms, it’s a giant capacitor, or more specifically, an entire server rack filled with capacitors. The Hackerspace uses it for experiments and demonstrations — but from the looks of their videos, they mostly just use it to blow things up, as shown in their 2008 Project Promo video. I think we would too. They even used it to blow up an iPhone! (Skip to 3:00 for the explosion). We think someone with a high-speed camera really needs to film Thumper in action!

The awesome CGI animation explanation of it is after the break.

Revenge Of The Glueless Stool And A New Folding Chair

September 18, 2013 by 17 Comments

glueless stool

[Vincent] is at it again, with the final iteration of his glueless stool and a new project.

As many of you commented on the original post, three legs might not be enough. He might have taken note, as the final design contains not 3, not 4, but five legs. After the break we have a clip of it being used, and it looks quite sturdy!

But is that it? Is [Vincent] done with innovative wood furniture? Nope. Not since his wife came up with a challenge to create a practical, foldable, and especially, not ugly — chair. He began by researching the dry subject of chairs and determined the approximate popliteal height that his chair should provide. Keeping with the theme, he wanted this chair to be cut from a single piece of wood, just like the stool. A few sketches later and he had a basic design ready, still glueless, but unfortunately this time requiring hinges. After a few hiccups in his CNC program, he had a working foldable chair, but our guess is it’s not quite the final design.

Just like last time, all the files are freely available from his Github, so if you happen to have a CNC router, or maybe a laser cutter, you can make your own!
