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 a lot of power, you [...]

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 local carpenter for the actual [...]
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. This is probably
the obvious choice [...]
Some of the table specs and materials:
- Projector 3m DMS 700/710 Short Throw at 1024×768 pixels

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 and will continue to post [...]
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
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. But now
I found a material that [...]
Mhhh, this post was somehow hacked, I guess

Since I have been recieving quite a few question about DI setups and how to build
them, I wanted to point everybody to a guide from the c-base group. They have build
a really nice table quite some time ago. and took the time to explain their setup
in detail. I habe the chance to meet them, during [...]
I finally made a new video today..
Featuring Pawels touchEarth plugin for GoogleEarth..
also some old and new flash demos..enjoy
Comments welcome
Articles and information about okinawa hotels and japan hotels at myokinawa.net
There are lots of discussions regarding what setup is the best.
So I tried to write up some pros/cons, regarding both setups, since
I have build both setups. Please feel free to contact me, I will add
your input to this post..
FTIR:
* blobs are nice and clear
* setup needs an led frame which you have to make yourself [...]
Microsoft Surface
I was lucky enough to grap a ticket for the exclusive Microsoft Demo of their
Multitouch Table “Surface” here in Zürich. It was presented by Stve Ballmer
and the head of the Surface Group. My thanks goes out to the
Swiss Design Institute for Finance and Banking, which supplied the tickets for
me and Christian Itten from [...]

I´ve gotten a few emails asking about my setup, mainly dealing with the hardware used.
projection surface
Lee Filter, 225 Natural Density Frost
The projection surface is actually a foil, that is used with professional lighting for
filmsets, photoshoots, events etc. So its really not intended as a rear projection
surface. Its fairly cheap, diffuses quite well and makes a [...]
