[WIP] [DIY] LEEP- Optics HMD
Posted: Sun Aug 03, 2014 2:04 pm
Hi MTBS forum!
So this will be my first post and my first thread here.
Thanks to a lot of information i build my first prototype within 2 hours with my smartphone from a cardbox... i managed to get Interaction with my PC with splashtop and FreePIE and VireoSMT
I also tried the combination of Tridef 3D and a gyro mouse but having 3 dof was far cooler and the wrapped screen was better than the plain SBS of Tridef.
Here the embarrassing prototype xD: (mobile phone goes in the back, lenses were from cheap binoculars)
So i was pretty amazed by the 3D feeling and getting immersed and i started to get thinking about my first real build...
So for the head mount i found my old ski googles which are pretty comfy. Maybe ill attach another headstrap over the head not just around..
For the housing i will cut from polystyrene packaging.
For head-tracking ill use a Polulu MinIMU-9 v3 http://www.pololu.com/product/2468 and conversion to PC will be done by my Raspberry Pi, i'll make the output compatible with the FreeIMU support of FreePIE (http://andersmalmgren.github.io/FreePIE/) (if you need the vireoSMT plugin you can compile it yourself or i could upload it somewhere)
I will publish all code i will use or write for anyone intrested in rebuiding this one.
For lenses i will use an LEEP system.. I was searching pretty long untill i found the principe of leep Optics and a sketch so i redesigned it in OpticalRayTraycer 3.3 http://arachnoid.com/OpticalRayTracer/ 1 square is 5x5mm (right eye)
after my first mesurements this should give me a FOV of about 120-130° horizontal
Right now my problems are where i could get such lenses and not be poor afterwards..
and i need a monitor with a driverboard and the highest resolution possible, i could even find a 1980x1050 7" screen but 395 € were too expensive im looking more for something about 100€ max
right now im sticking to this one http://www.amazon.com/JBtek-Resolution- ... h+1280x800
Seems ok and inexpensive for this resolution...
and last but not least i will use a HDMI with a twistable jack:
I'm thinking about adding X,Y,Z tracking but i'm not sure if I want it...
Any suggestions and ideas welcome
PS: I will start building aproximatley in about 2 weeks (wating for salary xD)
