do you need to view in darkness, can you use multiple cameras? Also do you not need to modify the lcd screen (assuming there is no FFC issue), as in, just put camera in place with other computer components, open up app and work? Me confuzzled. Do you need IR leds around edge either? Many thanks, good work.
@Owener94: Not exactly in total darkness. With CCV 1.3 from nuigroup, u can use multiple cameras. I didnt modify my LCD and my LCD doesnt have FFC issue, I just disassemble the LCD and put accordingly to fit the table. If you use FTIR method, then you have to put IR LEDs around the acrylic edges.
I've been reading up on how to build a FTIR table all week. I've actually started looking for material, because building one is going to happen! I noticed you did not use a projector... how is this possible? I haven't been able to find information on building one without a projector, yet!
@crunksamm: From what I know so far, FTIR table can be constructed using projector or LCD screen. It is possible to build one without using projector, which is using LCD screen as what I done.
@crunksamm: Yes, I just bought a LCD monitor (Samsung 740N), and disassemble it. You need to know which LCD have no FFC issue (mine dont have), check the LumenLab LCD database to see which LCD monitor have no FFC issue.
Sorry for the late because before this I can't post a single comment or reply in Youtube.
The LCD doesn't really require a cooling fan as it doesn't generate that much of heat that will damage your setup. I put because most of my parts are placed inside a closed box and therefore it will be better to have air circulation system.
i'm actually building one myself, but we've still got problems with the blob recognition through the lcd. We're using diffused illumnation.
You should try and add one of the backlight diffusers again, so one can't look "into the box" while the display shows white and the brightness is more even.
And also, did you figure out how to solder the LED's from NuiGroups? Cause I want to make this, but I would get totally lost for a while when it comes to the specifics there.
And where'd you get the acrylic/what was behind the extra power supply? Did you have one for the computer parts and one for the LED's, both inside the box?
Sorry for the questions, but you seem fairly knowledgeable in this field, obviously...
I saw your comment but I just can't post comment or reply previously, I dunno why!
Yes, I really use 30 IR LEDs, which are the combinational of 2 arrays of 8 LEDs and 2 arrays of 7 LEDs, so total 30 LEDs.
They are just a bit warm, not hot. Total power dissipated in the 4 arrays are around 4.82 Watts. I followed the wiring diagram and resistors suggested by led*linear1*org / led*wiz (replace * to .) for my LEDs arrays design and soldering.
I get my acrylic from one of the acrylic selling shop in my country.
I did have one for my desktop computer and one just for those LEDs, so they are two different power supply. There is reason why I do not want to power up those LEDs using the same power supply with my computer parts is because if something happened on my LEDs for example short circuit, then it just happens on the other power supply, but not the one you using for your desktop computer to prevent damage to your computer parts.
@ CrazyEngineerAsh: My next plan is to apply Rosco Grey to further reduce background infrared from disturbing my blob recognition. Also will roll a compliant surface to make the touch more sensitive.
@ normixxxx: I built my own plan and design, which took me few days.
ur mother should use this to use the iron or watch movies while she cook shows or for more oranis presenations when pointing out something to the family etc....
Really bad hardware specs, a little more power should make it even more responsive, still nice work.

@alextan87 So you just bought an LCD screen? or is that something that I need to look into and research as well...

Does it work wneh i torn the light on in the room?
Or i need a dark room?

I tried with light both direct and indirect shining from top of the screen.
For direct case, it for sure will affect the gesture recognition.
For indirect case, the gesture recognition still works well if the brightness of the light is not too strong.

Did you really use 30 LED's?
Won't that make it excessively hot?
And also, did you figure out how to solder the LED's from NuiGroups? Cause I want to make this, but I would get totally lost for a while when it comes to the specifics there.
And where'd you get the acrylic/what was behind the extra power supply? Did you have one for the computer parts and one for the LED's, both inside the box?
