Thanks Matt. Wayne & I are very proud of that beastie.

Here's a walk-around I did today:

Thanks for the walk-around. I get goose bumps every time you show your project.

The build is DONE! I wish I could have been there to see first light in person.

We still need to tweak the image warping, but that's just details at this point. It works!
Now that we've worked out the vast majority of the kinks during the design process for display #1, display #2 should come together much more quickly. I guess this means I should start cleaning up my office...

Heh. Yeah, you're gonna need every spare square inch you can find.

There is actually one more thing to make - the cap on the top of the whole thing. I'm thinking some 3mm black Coroplast would do the job quite handily. We can attach it using velcro. The display is quite bright even with the shop lights on, but it looks nicer with them off. We'll need a "blackout skirt" around the outside perimeter of the table too - black canvas would work there.

All I can say is "WOW" and then again "WOW"

Gene and Wayne,

You guys have been doing great work. Very impressive!
Best,
Mike

Thanks folks! The nice thing is that mine ate up all the growing pains so Wayne's build shouldn't take more than a few work days.

Just a few tweaks left. I'm going to be cutting parts for new projector mounts in a few minutes. The mounts I purchased are great for ceiling mounts. However, they're crap for what I'm using them for. You look at them wrong and they move.

This is VERY bad, especially when it takes 2+ hours to align the pre-warp maps properly.

here's the new mount:



It takes up the same space as the original (3-1/4") but can be locked into place much more firmly. The top bolt will hold the mount to the support frame and some sandpaper glued to the top will ensure it never moves once the wing nut is tightened down. I'll add a metal spacer to the pitch axis adjustment so it won't break the mount if that gets tightened down too much.
