Here is the InfinitEye open source hardware HMD project release v1.0, so people (
including Palmer Luckey himself ) can start to make their own build and modifications.
Special thanks to MSat for the name InfinitEye.
I don't know much about licences (especially for hardware projects) but I think something suitable for a project like this, is Creative Commons CC BY-SA (and to be credited by the "BY" part, my real name is Lionel Anton (I'm the author of F-ZERO for TI68k if anyone tries to google my name))
Specifications:
- Horizontal FOV = 180° (calculated)
- Horizontal stereoscopic FOV = 63° (calculated)
- Vertical FOV = (to be determined)
- Weight without tracker and head mount = 412g (measured)
- Weight with head mount = 512g (measured)
- Resolution per eye = 1280x800 spread over 121° horizontally (calculated)
- Bounding box of the headset (without mount) = 310x220x140 mm
The components I used :
- 2 x N070ICG-LD1 + controller board from
ebay : 260$
- 4 x Fresnel lenses FRL021 from
optolife (size 165x105mm, focal length 120mm, thickness 2mm, groove 0.3mm) : 20$ + shipping cost
- 1 sheet of expanded PVC thickness 2mm from
castorama (french hardware store, but I'm sure similar light weight 2mm thick and flexible material can be found elsewhere) 500x750x2 mm : 8.45 eur ~= 11$
- neoprene glue
- headmount from faceshield from
castorama : 17 eur ~= 23$
cost ~= 320$
Additional components :
- Zotac mini DisplayPort to dual HDMI from
amazon : 69$
- YEI 3 space sensor embedded for head tracking (
website): 99$
total cost ~= 500$
Now the plans (Version 1.0) :
(I have no website to host the file so I'm just leaving it attached to this thread for now)
I made the following drawing to compare horizontal FOV between this HMD, the Rift and the other HMD I own: ST1080
HFOV-Comparison.png
Note that in the drawing, I used the 7" display to scale the Rift but with the 90° HFOV 100% overlap which is less likely (I think it will be something like 115-120° HFOV with 80% overlap but we'll see in march
)

(I can't attach other pictures, 15 files is the maximum)
Next steps :
- paint inside top and bottom parts in black
- glue the small parts to the box (green ones to prepare the LCD rails and then the yellow ones to maintain the box)
- glue the box nose part
- glue the lenses (top and bottom)
- insert the left LCD from the left
- insert the right LCD from the right
- insert the pink parts to maintain the LCDs in place
- glue the box left and right part to close it
- drill the holes to attach the head mount of your choice
Steps that I haven't done yet :
- extend LVDS cables (or tape the controller board to the headset, simpler but heavier)
- add head tracker
- modify VireIO perception drivers to make them compatible with this design
- say goodbye to reality and enjoy VR
Feel free to ask any question and post pictures of your builds in the thread
