[Chris Rybitski] developed this low-profile robot to help move scenery on stage. The test footage shows it to be spry and able to move hundreds of pounds of cargo. The demo shows the addition of a wooden platform about twice the length of the metal chassis with casters at each end to support the extra weight. It seems to have no problem moving around with the weight of a couple of human passengers on board.
Crafty systems for changing huge sets has long made the theater a natural breeding ground for hacks. Balanced turn tables, rails systems, and the like are common place. But we think this has a ton of potential. Right now the electronics seem convoluted, as there is an Arduino running the motors which connects to the LAN using an Ethernet shield and that Linksys wireless router.
We think he should patch directly into the serial port of the router. If he loads DD-WRT or OpenWRT he can easily make the remote control a web interface. We also wonder about the possibility of making it a line-follower that can precisely position itself automatically using patterns on the floor.

The worst computer keyboard, ever
[Gerardus] found an old BBC Master Compact computer for $15. The only problem is the computer didn’t have a keyboard. It’s not a problem if you can make a keyboard out of an old breadboard. It’s not a Model M, but it works.
Emergency ribbon cable repair
[Thomas] works in a hospital. One night, a piece of equipment went down because of a bad ribbon cable. Doctors were yelling at him to get the equipment up and running so out of frustration, he took stapler to the cable. It held up until a replacement arrived. Check out these pics: one and two.
Nobody remembers Little Nemo: Adventures in Slumberland
Here’s [Alan]’s gigantic Nautilus art car with a huge mechanical iris. Just watch the video and be amazed. We won’t hazard a guess as to how much money went into all that brass and copper, but we can confirm an Arduino controls the iris. Check out the build page.
Light up street art
[Grissini] put up an instructable for a light box that displays [Bansky] street art. We’d go with some RGB leds and a [Keith Haring] motif, but more power to ya.
A theater wind machine
This wind machine was built by [Willaim] for his High School’s choir concert. It’s basically a concrete form tube with plastic lids taped on and a piece of pipe serving as an axle. The machine makes a wind noise with the help of some nylon pants.
After a visit to the local theater and discovering the use of IR 3D glasses (for films such as Avatar), the team over at Furrtek wondered how they worked, and more importantly, how the glasses could be manipulated to tick off audience members. While the original intentions seem a bit childish, they did mention that their final setup could also be used for a home cinema with IR 3D glasses.
Onto the good stuff: the glasses receive IR light pulses timed with the movie to black out the appropriate eye with the appropriate frame and producing a 3D effect. With the use of IR Investigator the team grabbed said timings; it was then simply a matter of building their own IR projector, and bringing it back to the theater to annoy the crowd setting it up for their 3D home cinema.
