Yo dawg, we heard you liked macs. [Charles] got sick of his Mac mini looking nice and pretty and decided to cram it into an old beige box. This old beige box just happened to be an old Apple II disk drive, so we guess that gives it some more street cred. The original disk drive sold in 1978 for $500. Man times have changed.
[thanks BluRy]
[Dave] sent us these fantastic instructions on how to hack a rear projection tv to be a multitouch interface. They’ve converted a 67″ inch TV by adding a couple of PS3 eye cameras and an infrared laser plane. There’s lots of great information, like how to replace the lenses on the PS3 eye cameras and how to create the custom fittings needed to make it all fit nicely. You can download the code, but it is Mac only. They claim that this is the first conversion of a commercial rear projection TV to multitouch, but we know better. You can see a video of it in action after the break.

[Pedram] Sent us his USB missile launcher interface project. He happened to have some of the USB missile launchers lying around. having lost their initial draw, he wanted to do something to spice it up. He wrote an interface in python so he could control the launcher via his iPhone. We don’t see how this is any different than controlling them by the computer, but he seems to have put a decent amount of work into it.
Touch screen interfaces are generally hard and flat. Impress tries to break from that tradition by making the display flexible. Allowing you to feel more like you are interacting with the display. In the image above, the circles seem to physically fall into the dent made by your fingers. Another application shows some rudimentary 3d modeling being done by physically pushing on the vertexes. This prototype is very interesting, we’d love to see much higher resolution on the input side of things. It states that it does pressure sensitivity, but we weren’t able to distinguish it in the video. Maybe you can, catch the video after the break. Maybe laying one of these on some foam would be another alternative.
For those of you who don’t recall, the Wiremap is a 3d volumetric display built from hundreds of tiny strands. An image is projected onto the strands to achieve 3d effects. [phedhex] has posted an in depth instructable on how to build a wiremap. He covers the construction with lots of good tips as well as giving links to the software for Windows, Mac, and Linux. Check out the video after te break to see some fairly impressive 3d patterns.
If you’ve ever wanted to play with tangible tracking systems quick and cheap, you might be interested in this super quick tracking surface for trackmate. Trackmate is open source software for physical object tracking. Making a surface for it isn’t that hard in the first place but this one is probably the easiest. All you really need is some Plexiglas, some c-clamps and a web cam. The whole thing packs into a backpack or over the shoulder bag. This would be perfect for live performances.
TinkerKit is a collection of 20 different sensors and 10 actuators. It’s meant to make prototyping of physical computing devices much quicker/easier. The devices plug into a Sensor Hub Arduino shield. There is also a similar hub board that can emulate a keyboard; it translates sensor input directly to key strokes. It looks like a very ambitious project and it’s still in development. We love the idea though and think the wide variety of components will foster better final designs. The TinkerKit site covers the current component lineup and there’s a demo video embedded below.
