@31alejandro90: you actually dont need the silicone compliant surface on rear di. As for me, I used 6mm acrylic as top and 7d513 on bottom. you would use acrylic on top and vellum on bottom

@31alejandro90: Me too, but that’s the beauty of this place! people are actually willing to help each other out. And yes, the sutup recognizes fingers and fiducials. In my opinion this is probably the best since he input is recognized directly on contact. Let me help you out a bit more though, here’s where i learned most of what i know:

hope it helps you too! and hope your project turns out a success!

Really great stuff here. I’m currently in the process of building one. I have an xbox 360 camera, the same 4 ir leds you have, using a card board box for now and a lame projector. I’m having serious issues with fiducial tracking. I’m getting strange blobs on the surface and was wondering if the ir leds were causing it. i have a 3mm plexiglass with an etch.... can you assist?
