I had no Space on the Ground for a Large Tv so i went for a eMachines V700 Projector and a DIY Mirror Construction called "MirrorPod" in order to Project the Picture onto the spacious empty ceiling.ExplosionDrawing should explain how to put it all together. While cutting out the Baseplate watch out for the 4x4x8 mm Bolts > dont throw em away they are used to bolt everything together(watch out for the 4x4 mm square holes). Depending on your Laser Settings you might still need some Acrylic Glue .Mirror Dimensions: 225mm x 140mm x 4 mm All SheetParts are Made from 4mm Acrylic.made @ http://www.Happylab.at
