We had a wonderful time over the weekend at the 2015 SXSW Create. I was really excited to see that there was a very large area set aside for the Hackerspaces of the Austin area and they took full advantage of that. Most notably, ATX Hackerspace who had multiple tables and was drawing a huge crowd.
This table is a good example of the demonstrations on hand. Primarily It’s a collection of ultrasonic theremin. The classic theremin uses oscillator-based sound production (we’ve been running a series on that concept) with a set of antennas that uses your body’s proximity to tweak that signal. This version mimics the user interface but greatly simplifies the skillset needed to produce the instrument by swapping the antenna for an ultrasonic rangefinder and generating the audio digitally. The more astute viewer will have noticed the instrument being held. I neglected to ask about this but it sure looks like a Holophonor which is another great seed idea for your next project. Update: it’s a Hulusi.
I do think it’s worth noting that ATX also set aside a lot of table-space for their members to actually work on building projects at the event. We’re big advocates of this rather than simply exhibiting finished projects. It doesn’t really matter what you’re working on; seeing a table covered with interesting parts and tools, being worked on by fun people obviously enjoy each other’s company is the core message of a Hackerspace… right?
I talk with [Gardner] about ATX in the video after the break, and make a quick loop around the display tables.

The Texas Advanced Computing Center has built one of the largest tiled displays ever. They arranged 75 30inch Dell displays in a 5×15 pattern. The overall the system has 36GB of graphics memory and 108GB of system memory. They intend on using the system to display very large data sets. If you think the size seems arbitrary, it is. They just happened to purchase five more monitors than the University of California San Diego.
Maker Faire Austin is happening this weekend, October 18 & 19, 2008 at the Travis County Expo Center in Austin, TX. Maker Faire is a showcase of all things DIY. You’ll see robots, sculptures, live performances, and other wonders including many of the projects we cover here every day. We enjoyed our time in San Mateo earlier this year and the show keeps getting better and better. You can see photos from previous events on Flickr. If you’ve got a chance to go, take it.
Uber-geek [James McLurkin] was in Austin recently demoing his robot swarm. He’s on tour with EDA Tech Forum. [McLurkin] has multiple degrees from the MIT AI lab and worked at iRobot for a couple of years. Lately, he has been working on distributed robot computing: robot swarms.
[McLurkin] was an entertaining speaker and had an interesting view of robotics. He is optimistic that robot parts will become more modular, so it will be easier to build them, and more importantly, faster to design them.

- “12 engineer years to design, 45 minutes to build”
