The acrylic frame

Well this weekend I finished the frame that will hold the acrylic screen (See picture). It cost me about £5 from the timber yard + alterations and cutting. If I had more time I would build a table like so many others have, but I don't.



I would have got more done but I was working on a novel this weekend, which I'm glad to say is finished, but I am currently re-drafting (see Dominic Took.com)

Today I am going to re-calibrate the screen using the software provided by Tbeta which interfaces with a flash application to provide interactivity in the form of a multi touch screen (It's pretty neat!). I hope to get a half decent video up on youtube sometime soon.

I will let you know how I get on...

Blob tests...

The set up works, but its configuration is a little unstable. But there are a few fixable reasons for this. I tested the blobs first of all (Blobs are impressions made onto the acrylic surface (The touch surface) which disrupt the infra red field.) So the first test was successful, I managed to create blobs just by using my fingers on the surface, however I had to use the opposite to the side I expected, to achieve this...which still has me a little confused.







That was last night, today I've been trying to re-configure the hardware. I set everything up on a more stable surface, though I have nothing built to hold the screen in place...which is going to become annoying. I've found out today that the LED strip at the edge is interfering with the software picking up the blobs effectively, without that I can't really go forward.

So now I am going to try taping off the LED bleed with electrical tape.

Moment of truth!

The surface is now complete, the first image shows the fabric stabiliser stretched over the surface of the acrylic and the projection fabric stretched on top of that layer. Now I'm ready to add the LED's and tonight I will know if all the parts, (Webcam, surface, software) actually work properly.








It's the moment of truth...
