"RA" a DIY 3d Printable Virtual Reality Head mounted display Fov: 120+ deg Weight: 1lb 8oz Cost: $450 Headtracking: yes video showing the FOV range.http://youtu.be/p10V3lca-DY video of RA in Use.http://youtu.be/pujeMSP6dmo Instructions You need a 3d printer with a large print volume, this was designed to fit on the Ultimaker, but I believe the Replicator should be capable as well. Total cost of all parts comes to around $450 (see BOM below) download the .stl files provided here and print them out while waiting for the prints, order parts needed from the following BOMhttps://docs.google.com/spreadsheet/ccc?key=0Ao2v9-uDggLzdHJkRDMxcUtrTWg3ajliZVBTSnFlQ1E this is going to be a bit of a work in progress, I am working on a complete build log, with step by step instructions, might be a week or 2 before it's complete, check back! (the exploded view photo here should give you an idea how the pieces fit) follow progress on my build at the mtbs3d.com forums.http://www.mtbs3d.com/phpBB/viewtopic.php?f=140&t=15247&start=510#p83258 Notes: the zip file contains the gerber files needed to make an LVDS -> HDMI breakout board, just send the zip to a place like itead studio etc. or etch your own. you need to print 2 of the RA_HELMET_MOUNT.stl, the 2nd one should be mirrored There are 2 "Lens Plates" in this design, one for a LEEP optics variant for the 120+ deg fov, and another that uses 50mm lenses, that give you a 90+ deg fov. the choice is yours, if you do use the LEEP optics, read the notes below regarding the lens grinding jig. if you printing the leep lens holders for grinding the lens edges, you need to do the same, print 2 of each and mirror the 2nd one, for left/right lenses. the holders are used to clamp the large lens of the 2 lens set, you then use a belt sander to grind the edges down till they are flush with the printed jig. simple..
