TwoBitCircus: The Business of Building Interactive Entertainment

The Hackaday 10th anniversary was an awful lot of fun, and part of what made it awesome was all the cool things that the community brought to the event. We hadn’t really had a chance to get down to meet the guys from TwoBitCircus before now but they were more than happy to bring along their excellent Hexacade machine. The 6-player custom built arcade game that was an absolute blast!

After the party TwoBitCircus’ fearless leaders [Brent Bushnell] and [Eric Gradman] invited us over to their space for a quick look at their workshop, and to give us a personal invite to the Hacker Preview day for their upcoming STEAM Carnival. No this isn’t Steam as in Steam-punk, but STEAM as in Science Technology Engineering Art and Mathematics.

Their space is really quite amazing, part of The Brewery Art Colony near downton Los Angeles. The building is actually an old steam power plant with incredibly high ceilings. The TwoBitCircus crew is now about 30 people all building interactive games and art pieces for events. They call themselves a digital circus and a lot of their work harkens back to old carnival games of yore with a new digital twist.

[Eric] and [Brent] spared a few minutes to give us a quick run down of what sort of games to expect at the STEAM Carnival. There will be a wide array of entertainment: giant marble runs controlled by see-saws, whack-a-mole/twister mashups on huge glowing button walls, laser based foosball, and the more extreme immolation dunk tank! It will be a most entertaining and educational event. The main public days are on the weekend of 25th – 26th of October, but there is an invite only hacker preview for the local community on Thursday October 23rd which we will be attending. If you’d like to go to the main event, use the code HACKADAY for $5 off the ticket price of $25.

What was most interesting about TwoBitCircus for me as a maker of things was how these guys have turned their hobby into a thriving events business. Brent tells us that they’ve been at this for 8 years now and the company has been around for 3. They’re doing pretty well too, making incredible things for some of the biggest companies around. This really is the best possible job for any inventive hacker sort, building crazy stuff all day for people to play with! I left the place feeling incredibly envious.

Check out the photos below for some impression of the sort of craziness you might see at the carnival!

Musical light show is far less complex than you might think

color-changing-light-tube

[Matt and Jason Tardy], who make up the musical performance duo known as AudioBody, were recently featured on Make: explaining how they put on one of their trademark segments. The most popular portion of their show features color changing tubes of light which the pair spin and fling around not unlike a higher-tech version of the Blue Man Group. While the visuals are pretty slick, the technique behind it is far simpler than most people initially imagine.

As you can see in video below, the tubes look to be nothing more than simple white lights. As the brothers work through their performance however, the tubes switch from white to blue and back again with a liquid-like transition between the colors.

The [Tardys] say that most people peg a microcontroller or other complex electronics as the source of their light wizardry, but the real answer is much simpler. Embedded in the end of each tube is a bright LED flashlight. A sliding blue filter positioned inside the tube provides the silky smooth transition between colors – no fancy electronics required.

If you would like to see how they were built, be sure to swing by the AudioBody web site for a how-to presentation by the [Tardys] themselves.
