*Updated Video 3-2-08*
<center>

New video - 3 - 3 - 08

So I’ve been tracking my progress on my blog, but I’ve been so busy I haven’t been able to update with all my current progress. It’ll take me a couple weeks before I can update the blog with proper documentation, so I thought I’d do a quick post here of the (almost) final table. =)

Updates *3-02-08” - Pictures of the inside of the box!

The black thing on the left is a 6A 12V power supply. It’s powering the other things you see on the left. A 200w amplifier/eq and a firewire soundcard on top.

Right side is a power strip. I have a bunch of things that need power. Leds, soundcard, amplifier/eq, projector, camera. You can also see the right speaker.

The mirror is mounted to a wood board and has hinges in the front (you can see the screws coming out), which secures it to the box. Then L shaped brackets are setting the angle under the mirror. The camera is taped (for now) to a wood piece that is fits in between some brackets that are mounted to the box.

The projection goes slightly over the mirror but that isn’t a problem since that part doesn’t need to hit the screen anyway.

Projector and screen.

You can see that the projection is slightly over in the front.

dsc01683ls7.jpg
Left side of screen. The projection is over by a few cm (inch or so).

dsc01684tf2.jpg
It’s hard to see, but the projection is slightly over on the right by a few cm (inch or so) also.

</center>

I still have to put on the other side of the box which opens up on hinges from the top. I’ll post on that once that part is completed (hopefully in a day or so)/

I’ll be updating this post and my own blog with more information/pictures (such as how I did the paint, and wired the speakers (there’s 4 of them), sanded and prepped the box etc). Questions/Comments are welcome. =)

Looks great Cerupcat! Can’t wait to see inside… I’m working on one about the same size as well using DI. Looking at the video the screen operates well in a relatively dark environment. How well does it operate in a room with normal or soft light? I’m trying to make my table so that you don’t have to dim the lights TOO much to operate it well.

Hi fairlane. The only reason I darkened the room was so the video camera could see the projection good. The screen works well with all the lights on still. My table is FTIR though. I’ll post some inside pics as soon as I can.

great work cerpucat!
What aspect ratio is it? Doesn´t look like 4:3 or 16:9 really.
Maybe its just the angle of the pictutures too smile

I really wish I stayed with piano classes when i was 7…

Thanks Tim! You have a great eye! You’re right, the screen size isn’t 4:3 or 16:9. It’s actually in between. I originally didn’t consider the aspect ratio when I started construction since I wanted to go with that I thought was a good “useful size.” I liked the idea of widescreen, but I thought the width wouldn’t be big enough compared the the height if I did that. The screen is 22in x 35in (56cm x 89cm). So it’s like 8:5 ratio.

Well I just run natively what my projector runs which is 1024 x 768. Yeah, I’m loosing some projection space but very little. Almost the same amount if it was normal ratio. The projection is about 1in (2.5cm) over on each side of the width and then about .5in (1.25cm) over on the length side. So that’s really not much more than you’d loose if doing normal ratio since you want to make sure even if someone bumps the projector the slightest bit that it still covers the whole screen (so I would make the projection slightly bigger than the screen space anyway). It’s hard to say if it it would have been better to do a normal ratio or not; I really like the extra space I get on the width that I wouldn’t have if I went widescreen.

I’ll try and get a picture of the underneath so you can see how the projection lines up.

Haha, ya. The speakers sound mighty fine too. I’ll be posting about them at another time. =)

Looks really good, cerupcat. I’m very interested in seeing an internal diagram of your projector/camera/mirror layout. Great job!

Great work Cerupcat!  Did you spraypaint it or brush it on?  The overall display looks very clean and minimalistic, I like it!

Great work!

I am interested to see the inside the box (the placement of projector, cam and speakers.....).
If you have used the mirror, what are the dimensions of the mirror with respect to screen ratio 8:5?
and does it has any effect on the projected distance (from projector to screen)?
