Multitouch Display: CD burner infrared laser short test
This is a very short post compared to the ones that I write normally.Anyway, I was looking around to find how I can achieve the great results that AlexP got in his laser multitouch. I really suggest you to read that link, Alex method is really cool!So, basically I was guessing where I could find a suitable infrared laser to use for generating a very thin flat plane of infrared light just in front of the multitouch screen.Googlin' around I found that the laser included in the DVD player/burner is not good as it is a visible red laser of...
Multitouch Display: a plexiglas case for the LCD FTIR multitouch (part two)
Look at this, isn't it wonderful?!?! Yessss!!! It looks very very nice!Anyway, of course it is still to be completed, I need to prepare all the braces for the circuit boards, the bracket for the webcam and, of course the infrared setup and the front mask.So, let's start with this second part of the construction notes! After bending all the parts, I had to refine them because, as I said, I abounded with measures because I was not knowing how much material I would loose with the bend. In this phase I discovered how useful is the circular saw for...
Multitouch Display: a plexiglas case for the LCD FTIR multitouch (part one)
As you surely remember, three weeks ago I posted about my first test with an LCD panel for multitouch applications. I saw that it had enough chances to work out but I was so scared about the fact that the bare LCD panel is extremely delicate. So, as I was saying at the end of the post, I started to think, then work, to a case for this multitouch display.Of course I thought about a case that should also look nicely, what's better than a plexiglas one? So, after some weekends of work, this is how the case is looking...
Multitouch Display: testing LCD screen panel for FTIR
Quite a long time has passed since I did something more for my multitouch display. My last post on this topic was on November!Unfortunately I did not any progress basically because I don't own a projector, so, everytime I should ask to someone to lend me a projector then I have limited time to do some tests with it. This is not exactly comfortable especially because I have very limited spare time and quite never in consecutive days.So, in the last months, I was thinking more often that it would be nice to achieve the goal to use an LCD...

Multitouch display, build your own: silicone rubber and a wooden frame
Finally I decided to build a wooden frame for my multitouch display. Basically I'm trying to build a light frame that may hold the plexiglass with the alluminium frame holding the IR LEDs together with the projection surface and the compliant surface that I'm going to make with silicone rubber. Here you can take a look at the actual stage of the wooden frame, it is quite complete, the glue is drying! On the right side you can see the silicone rubber I bought to make the compliant surface.Once the frame will be ready I hope to handle more comfortably...
Multitouch display, build your own: the video of my first test
Probably you already saw the page called Multitouch Display. which is in the Projects section of this site.Probably you were just scrolling it trying to figure out what this bunch of LEDs, wires and plexiglas are used for.Probably you perfectly understood what that page was talking about but you thought that it can't work.In every case, I was finally able to upload a video that I recorded the first week of August, it is the video of the first test of my Multitouch Display! Here we go: Please excuse me for the poor quality of the video but my camcorder...
