DIY Goggles - The Facebox - great and cheap FPV Goggles (alternative to Fatshark Dominator HD)

From the comments on my Fatshark Dominator HD review I see that this is a hot topic. So many questions about alternatives to the expensive and hard to get DomHDs.
One really good one is also the cheapes one with extra large picture, good quality and good comfort. I saw these first on a FPV meet (Poolnoodle Challenge) and was amazed by the clear and huge display. Pricing is around 100$, buildtime maybe 1-2h - but really easy!
If you have some questions, comments - don't hesitate! Good luck with the build and have fun!
Check out my blog post here for more details and all the pictures (which are also in the video at the end).
Short shopping-list:
1. Frame (styrofoam) from UK http://goo.gl/pikyzS
2. 5" TFT display from Dealextreme http://goo.gl/Vd419Y
3. better fresnel lens (optional) http://goo.gl/TlJlzp

►►Update: just before publishing this vid I did a 2nd testflight with the MiniQuad. The picture is really big, great to fly BUT: the blackscreen issue can be tricky/scary. So not sure yet if I'd trust this goggles for an expensive, bigger, unstabilized platform. So if you have some other safety features (second monitor for emergencies) it's ok.
Hover recommended routing it throug a DVR - this might eliminate the black/bluescreen. Or optimal: search for a similar size display without bluescreen.

Hallo RCSchim,

danke erstmal fuer die infos! Ich habe die billigen FPV Brillen nachgebaut und verwende ebenfalls die flexible Fresnel Linse die Du empfiehlst.

Insgesamt finde ich das Resultat sehr gut aber ich bin nicht so zufrieden mit der Linse. Das Bild koennte besser sein und ich spiele mit dem gedanken die vergoesserungslinsen von einem Kopflupe zu verwenden, zB. http://www.ebay.de/itm/Neu-Profi-LED-Stirnlupe-Kopflupe-Lupenbrille-Brillenlupe-Licht-Lupe-/121419296235?pt=Uhrmacherwerkzeug&hash=item1c45276deb
Hast Du da empfehlungen oder Erfahrungen damit?

Danke nochmals

Gruss

Mark

hi, ich find die große Fresnel Linse (von ebay) recht gut. Kaum verzerrungen. Hast die vielleicht falsch herum rein getan? Bin nicht sicher aber ich glaub die Rillen müssen richtung screen schaun.

Und ein wenig geradebiegen schadet auch nicht.
