Some info on the table:
Box:
My tables dimensions are roughly 60cm(l)x80cm(h)x60cm(w) and screen size is around 60cmx45cm roughly again.
Box is made up of 12mm MDF from bunnings. One of my graphic designer friends donated the vinyl and other one covered
the box with it which gives a smooth glossy finish.

Screen/Diffuser: I used acrylic and white plastic table cloth as a diffuser and projection surface from Warehouse in Melbourne.
I tried clear frosted film and frosted glass but I think this table cloth thing is better projection wise. Ill try different materials in the future and report here.

Projector: Projector is Sharp Xr-10x. great when it works. it is famous to blow lamps prematurely. I bought it with a burnt lamp then changed
the bulb with a new one from chine which costs 50$ shipped smile. this bulb has 60-70% brightness of the original. you get 100% brightness with most projectors though.

IR Illuminators: I used 4x of 48 led illuminators from china bought a 12V 2A power supply with 4 outputs. I think Ill get another one to illuminate
the center which should give better coverage.

Camera: I used Xbox live vision cam after Fairlanes suggestion. Its very easy to remove the filter. I used 2 layers of exposed film.

Mirror: Mirror is a 4$ mirror from warehouse. it makes ghosting but not that much.

Fans: two 120mm fans. one is intake the other is out-take smile (what is the word?) smile
I know I need grilles for them :)

the box is also 4 wheel drive with four furniture wheels from bunnings :)

hi, nice MT

a am buliding MT table too. i will use DI tehnology. i have ps3 eye and two ir reflectors but a am wondering what you use for diffuser. i dont have any idea about what to use for good diffuser

[efendy2]

First of all, if you've got budget try to add another 2 of the IR illuminators. of course if you go for a screen size as big as mine. for the diffuser, I used a $2 disposable table cloth from warehouse in Australia. People at nuigroup forum (cradle of amateur MT) used the same table cloth and got good results. and lately a guy found an American equivalent of the table cloth. If you're in USA I think you can obtain it. check out the related post here nuigroup (.) com/forums/viewthread/3176/P45­/

Excellent and very professional build, be proud. After watching several videos, i have decided that DI is the way to go, My projector is coming, as well as my IR. one question though. I am thinking of using the WII remote, since it is an IR Sensor. But it only has the capability of tracking 4 blobs, have you really needed more that 4 points in using your system?

[efendy2]

Hi. Glad you liked it. I had no experience with Wii. Actually I havent thought about how many points I am good with. But it is good to have the freedom of using all the fingers at the same time. after all MT used at home is to show off to friends :) and you need applications in which you use all the fingers :) I say dont limit yourself to 4 points

cheers

Hey mate..what exact camera do you use?

[efendy2]

I used Xbox 360 live vision cam, IR filter replaced with two layer of photo negatives.

cheers

Is there much multitouch software for mac at the moment?

[NateTheGreat555]

Hey, I'm making one as well. Do you think frosted glass would make a decent diffuser? I found a cheap 18x24 inch sheet that's 1/4 inch thick for 22 bucks...

[efendy2]

hey thanks for the comments! camera is AUD 45 and projector cost around AUD 250 as I bought one with blown up lamp and refurbished it with a bulb from china which costs US 50. another AUD 200 on other stuff like illuminators and the box itself. around AUD 500. check nuigroups for more info

cheers
