diy is cheap (relative).
for about 250 dollar’s you’ll have all the items needed, and no need for a laser cutter.
a bit of electronics, woodworking en patience and you’ll have a good solid table for a whole lot less.
a projector goes for about 400 dollars here (netherlands), a simple wooden table to use as a base is 50 dollars (IKEA :P). that makes a grand total of about 650 dollar. that’s a complete table.
software comes from the almighty internet or the guy behind the keyboard. or from the touchkit site, as their code is free (see faq).
so that’s 4 complete tables for the price of 1 expensive touckit.

actually the specific material they are using, just for the back piece cost a few hundred dollars and the camera again is a few hundred and the time to cut the pieces cost money (unless you have a laser cutter, but then you’re looking at a 10k piece of machine)

I tried to DIY, it cost a lot more then you’d think.

$$: While that may be true for you, many people (such as myself) don’t have access to the equipment to build one of these, let alone with such quality.

seems to m they are charging thousands of dollars for about 60-70 dollars worth of materiel, instructions and code can be found all over the net, and its just two accrylic sheets sanwiching ir leds and a translucent sheet, seems a little ridiculous to me.

I agree with $$, a bit steep for a part.I would be curious as to how many they actually sell at that price. I just assume build myself.

For that price, you think they could include a projector!

Build your own for less than a 1/10th of the cost of this system.

This will work with any optical multitouch system not just openframeworks tracking soft! There are a multitude of freeware blob trackers out there and playstation eye cameras can be modded easy to work with FTIR, LLP, Rear DI.
