    Bobs ECO Goggles

    Hi All, first post, so be gentle ,

    One rainy evening i was thinking that goggles were a tad overpriced when you look into what involved with them. I thought there's got to be a diy solution to this.

    So I gathered some bits from the "bay" and started fiddling.

    The item list was
    1 x 3.5" 640x480 colour LCD screen, used for rear view parking on cars 15
    1 x credit card lens 1
    1 x AV lead 2

    I made the black epp case on my cnc hot wire

    I was not that optimistic , but the result is very good indeed, i have tested it with a few pals who use fat sharks (as do I), and they were amazed especially for 18 (approx 28 USD).

    the screen is at the back so you can get to the adjust buttons easily for contrast / brightness etc.

    The credit card lens is in front of the screen, this is the key to it all, and can be moved back and forward so that you don't go cross eyed

    Would certainly be good for a secondary unit or even a primary viewing unit.

    Super cool! I was thinking about making a set like these. I really like my video goggles, but these could offer a much bigger screen in front of your face.

    Hi Vitamin J,

    I have not attached the strap, that i will steal from a head light, the image is a little bigger than you see through conventional goggles, but its brighter and very clear.

    Its very light too...

    Cheers bob

    I had a look through these today, I was a bit sceptical when told about them but they are a lot better than I imagined.
    Much clearer than fat shark base model and much brighter too, also would work better than trying to view a screen when out at the field due to the light blocking.
    Good cheap option to standard goggles

    This is a great solution in a small package. I've been using something similar for the past 6 months but on a larger scale. I
    've been meaning to document it in it's own thread now for some time. It's basically a coroplast box with goggles on one end, a 10" LCD on the other with a high quality fresnel lens in between. It's as immersive as it gets. I estimate the FOV to be around 90 degrees as it almost fills your peripheral vision. I got the idea from commercial plane simulators which use fresnel lenses in front of their screens not only to magnify but to force the eye to focus at infinity. This fools the brain into perceiving a sense of depth. It really works! The only thing missing is an HD video feed to make better use of the perceived screen size. Will post a few pics tonight if I get a chance.

    I've been thinking about trying something like this as well for passengers. Does it not feel heavy with the screen being several inches out like that?

    That's cool man. I need to whip up a set for passengers. Is this similar to what you call "credit card lens"?
