I've got some upgrading going on. First, I procured a new projector. I was worried the old one was running out of bulb life, and I borrowed it. Similar throw distance, well a little less. And I decided to switch from FTIR to DI for an upcoming event. So now I can just get a now projection screen and solid surface and be set until the next build.

I didn't want to purchase IR emitters from anywhere and have to get all new IR filters for my webcam, so I decided to make my own. In a process not too different from making the FTIR sides, I made light emitting bars, I figure a string of lights would cover more evenly compared to a spotlight anyways.

And I didn't want to keep using the wood rails I made for holding the first projector. This time I opted for aluminum. Plus it'll be good practice for my next build, coming soon hopefully, just waiting on a little more seed money. The metal was much much more stable than wood btw.

So a final test with CCV. Success. The only fault is that the screen is off a little, skewed a little, but with the app I'll be using in an upcoming event I'll be able to crop in the screen a little and no one would be the wiser, except you reading this post...maybe I shouldn't put this in then. Oh well. (^_^)// Build and Learn...and experiment. CCV was running about 30-60 FPS solidly (mainly cause it is hooked up to a slow computer).

Then one this I'd like to point out is a combonation of a screw thread and nuts and washers to help fine tune the mirror. But I think I'll be looking into a front mirror thing, I'm tired and forget what its called exactly. [Surface! Front Surface Mirror, thank you fashionbuddha, first to fill in the blank]

And what kind of build would it be without some type of battle damage? A boring one right? POW, scratch from a drill bit. DONE!

Now time to fine tune a couple of last bits. A new top and some sides. Luckily still enough time to not worry about everything. But check back in 3 weeks, I may be freaking out about the time left.
