http://iad.projects.zhdk.ch/multitouch Fri, 21 May 2010 06:54:29 +0000 http://backend.userland.com/rss092 en So now that we have finished the LED Frame, we will need some kind of power supply inside the table. Like many other DIYs, I use a standard PC power supply. They are cheap, available everywhere and can be used for the LED  frame and some fans as well. Since most modern pc use ... http://iad.projects.zhdk.ch/multitouch/?p=190 Undoubtedly, one of the most important parts of any MT system is the box. Because this is not really my field, we asked a fellow industrial design firm in Zurich to assist us in the design and construction of the box. Plans where made with my inputs, and finally handed over to a ... http://iad.projects.zhdk.ch/multitouch/?p=177 I first start with the LED Frame, which is still handbuild by myself. In retrospect, I would use SMD Leds today, probably already assembled and ready to go in LED strips. But since I would like to make all tables exactly the same, I still use normal IR-Leds and a custom build frame. ... http://iad.projects.zhdk.ch/multitouch/?p=118 Some of the table specs and materials: - Projector 3m DMS 700/710 Short Throw at 1024x768 pixels - PTGrey Firefly MV (640x480 @ 60Hz, 320x240 @ 120Hz) - Osram SFH-485p Leds - EndLighten "L" Plexiglass, 10mm thick - Lumin Contrast Screen - PC Power supply - MacMini 2 Ghz, 2GB RAM - Pabst PC Fans (6 Alltogether) - Sony ... http://iad.projects.zhdk.ch/multitouch/?p=141 I am in the process of building another (the fourth one) IAD MT08 Table, which uses the DSI (Diffused Surface Illumination) setup. Since I get a lot of question regarding certain details on hardware, I will now share some infos on how I build one. I will start of with the LED Frame ... http://iad.projects.zhdk.ch/multitouch/?p=116 For the DesignMiami (part of ArtMiami), we are doing a little installaion with two cubes and some nice screens. Some pictures of the building process of the new cubes and the packing :)   [gallery]     http://iad.projects.zhdk.ch/multitouch/?p=104 The main Problem with most Diffused Illumination Setups is getting IR Light to spread evenly across the screen surface. Normally, you use a couple of IR Illuminators as a IR source, and it takes lots of effort to get the IR even, while also dealing with possible reflections from the Illuminators.
