2 Place Collimated Display

IT WORKS!!

Go to http://youtu.be/LrvjA6dF0PY for a short video.

Was hoping to do a flying demo. Unfortunatly, was way too successful in sealing the chamber and the mylar draws down to the collimated position and beyond with the vacuum pump running at the minimum speed and the controller and pump have to be turned off after a few minutes to avoid over stretching and damaging the mylar. Also need to install and position the two side projectors. The yellow vertical and horizontal lines are reference/alignment aids.

Hope you enjoy the video. Now I have to buy some HD 1920x1080 projectors. Cha-ching!!

Cheers

YAHOO! EXCELLENT!

See, I told you there was no need for a fancy vacuum system. Now ya gotta find a _small_ shop vac.

You should shoot a walk-around video showing just the mirror with no image on it.

Congrats!

Very nice work. I'm with Gene... a nice walkaround video!

That looks Great! How's the depth effect as you reach the proper draw depth?

Fair question. At this point, hard to say. Was unable to sit in the cockpit as I had to monitor the mylar draw and disconnect the power to prevent overdrawing the mylar. I did not expect that. With the shop vac set at the absolute minimum, was unable to use the active arduino controller. So I tried turning on the vacuum until the mylar touched the reference point, counting to three, killing the power, and then running back to the cockpit. One thing I did notice. Being unable to fly, I set a visual view point high above the runway in a later trial. While it was fleeting, I did have a real sense of being in the air and looking over the nose down at the runway as the mylar started to relax.

Going shopping for a small portable car vac or something similar. I thought of installing a small air valve on a section of the exhaust pipe, but that might produce a whistling or hissing sound; beside using less power is always the better option.

Okay, by popular demand here is a short video of the mirror setup

That's great! Thanks for posting it!

I had to laugh at the walls - it just goes to show that building a simulator requires a padded room. *laughs*

EXCELLENT video, thanks for the walk around! It sounds like your projection screen is about the same size as mine...and if you ended up with a 17ft frame for the Mylar, that means my planned 20' room will just about do the job. Good to know.

Gene: I'm thinking that's not for mental condition, that's for when you build a motion platform and the darn thing throws you off like a bronco.

Don't recall if I mentioned room size in the video, the room is 22x17. At 20' it's doable, but you mind find it a little tight. You will need to access the top of the frame to either mount projectors or fold mirrors. Best to do that from the back side, especially after you've attached the mylar.
