    DIY Goggles and Head mountable displays and other ideas and projects

    EDIT: UPDATE
    Welcome to the DIY Goggles and other cool projects thread.......I am editing this first post after about 300+ post and wanted to let anyone new to this thread know it is FULL of info and links and is worth the read. .

    Below is where I keep the ''Highlight Posts'' (kind of an index) and links to the pages they are on so you can navigate the whole thread easier.

    If anyone sees a post they think should be highlighted please pm me the post number. Keep in mind the post before and after will have info as well.



    INDEX INDEX INDEX INDEX INDEX INDEX INDEX INDEX INDEX

    Link for 2.5 inch displays...........http://www.artronic.pl/o_produkcie.php?id=1246?

    This is the INDEX for the thread.......the links will get you to the right page then just scroll down to find the post number....Have fun!

    Post #1 Bottom of this post is the original post that opened this thread. I kept it here just to keep the thread in tact despite the addition of the index. I thought the index should be put first now because it is getting so long now.....lol
    No link....just scroll down to the bottom of this post #1

    Post #10 (bottom of this page), #21, #43 and #47 These are the post numbers my build thread of the Head Mount Display (HMD) that started this thread.....Its kind of scattered throughout, but the page and post # is published at the bottom of eaach installment so it is easy to navagate.

    ORGINAL POST BELOW

    I noticed that if you do a search on FPV lab for ''DIY Goggles'' not much comes up that is useful to the DIYer either.......not even Bobs thread. So with that said I decided to start this thread so it will be easier to find for others, a good source for ideas and of course a place for us to show off our projects.

    I will start.

    I have some pictures of my DIY goggle projects over the past year and I have finally come up with one that I think is a winner. It's comfortable, user friendly, and relativily cheap and easy to build. It is also my ground station......all in one, no wires to plug in at all. The only wires you would need is if you were to plug in a DVR or another set of goggles to it.......and it all fits on my head.......and I look stupid as Hell....lol. When I came out of my work shop all proud of my design my wife looked at me and said ''If you ever want to get laid by me again you will take that off your head right now''....LMAO. Of course she was joking (I think) but on the good point she said they were way better than anything else I had built.......(I added the ''way better'' part.....she actually just said ''better''......) Luckily I am not in this hobby to get laid......Which she responded ''obviously!''

    Anyhooooooo......I digress

    Here are some of the designs I have come up with over the months. The last one I will be doing a build log on here very soon.....tonight probably. (Edit: build log starts at post #10) In the mean time feel free to post some of your ideas and pictures.

    My first attempt.......obvious problems here but it worked really well and was very immersive. The hood is made out of dollar tree foam board and it has a Fresnel lense as do all of the other ones I have built. This one had what seem like 50 wires comming out of it that I had to hook up, but one of them was the head tracker that you can see on the top of the helmet. It uses a 7'' inch display.

    My second which I was happier with. I actually just took the visor off of the helmet and attached it to an old welding helmet head suspention set. It worked really well but still had wires.

    This is a set of the Bob's ECO goggles that I built out of the foam body he sent me......the body is hot wire cut foam. I zip tied them to a set of ski goggles that I had replaced the lense in with a Fresnel lense. It uses a 3.5 inch display off of ebay.

    And finally here is the newest one that I am doing a build thread on very very soon. This one I am proud of. It has nothing but an on off switch to worry about. It is entirly self contained with the VTX (5.8) incorperated into it. Just put it on your head and turn on the single switch and you are ready to fly. It uses a 7'' non blue screan display and a Foxtech VTX. It has plugs to plug in a DVR or a passenger set of goggles but then you would have external wires. If someone wanted you could build this with one of thoes 7'' displays that hav a DVR built in.......its only money...lol
    I will cover this goggle in much more detail in the build thread.

    Search Philips PD9012


    Fresnel lens sources…
    Honestly... whatever you can find. Turns out it's not terribly critical. 3X is good, any stronger seems to cause distortion. Full page, A5 or at least bookmark size (credit card can work but you'll have to mess with 1 per eye and that gets you into IPD, lens shift and keystone issues... )
    Ebay... search for 3x Fresnel then look for the focal length.
    Amazon... if it doesn’t give any specs, check the reviews for focus distance (4-5 inches or less)


    Cheers,
    Vince L.

    I am looking forward to your review on the lense from www.3dlens.com. I have always used the ebay ones and had great luck but I havent been able to compare them either. I just wonder what ''better'' looks like.....lol....it will be interesting to see.

    Thanks for droping in and posting. I will get my build up as soon as I can.

    Just tried one of those page bookmark fresnels after reading about this experiment over on mtbs3D, must admit the groove pitch is finer than I expected. Focal length is a bit long (200mm) though (=long box, small FOV). 120mm would probably be good. edit: the lens i tried was this one, not the one referred to in the mtbs post

    Not happy with the 2.5x headband lens solution after proper flight testing: FOV not wide enough (for me) and more crucially eyes started feeling strained after 10mins or so.
    However it spurred me into figuring out how to mod my RCV922's and now life is SWEET

    3DLens lists their bookmarks as 120mm focal point, so they should allow a shorter hood. You can also cut them in the center and move the pieces inward to try this Prentis Rule stuff to avoid eye strain.

    They have a $10 minimum, so I grabbed a bunch of bookmark lenses (2.5*7.5 in) plus a few "pocket" lenses (3.75*5.3 in). I’d also like to see if using the bottom of the lens will offset the screen vertically so it can be lowered and shorten the moment arm... but that's for later.

    I know the vertical thing works.......I used it to slightly compensate for the droop of the first wleding helmet type hood I built. It was heavy so it would drooop slightly. I simply used the right part of the lense to bring the screen back up to center......works like a champ. I also experminted with the prentis rule a bit but wasnt succesful with just holding pieces of lense in front of each eye....lol...I wasnt trying to hard......I just happen to pick up a couple of pieces of lense and goofed around with them.

    After experimanting with several designs of DIY goggles and/or head mountable displays I finally figured out what I was looking for in a design.

    First...........it had to be comfortable. DUH! I want it to be easy on the head and easy on my eyes.
    Second.......it had to be practical. In other words not so expensive or hard to build that just buying off the shelf goggles woud be easyer.
    Third..........Easy to use. Not a bunch of cords to plug in and get tangled or pulled out at the worst time.
    Fourth........I dont want it to blue screen at the worst possible time either. If that dosent make a guys nut sack tingle......lol
    Fifth...........Good looking.....at least to other FPVers. I know Im not going to win a fashion show and if I walk through a Post Office or airport I will probably get arrested......but to the community of FPVers I wanted it to be presentable and make pilots want to try it on even if they give me a bad time doing it.........then I want them to say ''Wow.....nice!'' when they do try it on.
    Sixth..........Off the shelf components.

    With that laundry list I set out to build this my most successful DIY goggs yet.....Which you all probably saw in post #1

    I built it out of this stuff......Yes thats a bathroom garbage can, a grinding shield with a knob on the back that tightens the head band, a Fresnel lense, a 5.8gig foxtech receiver, and this 7'' non blue screen monitor I got off of eBay
    http://www.ebay.com/itm/Feelworld-8-...item27cad00eaa
    As you can see I stripped away the outer case of the monitor down to the screen and PCB's as well as removing the VRX from its case. I need to get rid of as much weight as possible......LOL

    So thoes are the components I used. I got the grinding shield and trash can at my local hardware store and the VRX from hobbyking but they are available on ebay also. The Fresnel lense came from ebay as well......just search fresnel lense and get the page size cheap lense. There are more expensive ones you can use from www.3Dlens.com if you like but I havent tried them yet.
    Like I said the monitor is a non blue screen monitor which means that it will not go blue screen when it loses to much of the video signal. Our friend Flying Monkey tells me that if you put a DVR between the VRX and the monitor it will keep any monitor from blue screening because the monitor senses the DVR regardless of the quality of the video signal comming in. Either way you go the cost will be about the same......or just go with a cheap monitor, dont push your video range, and hope for the best......My first displays are the cheap ones and I got tired of holding my breath everytime it blue screened so I bought this one.
    So there is your shopping list.......go down and get this stuff so you can follow along.....lol. Just kidding....... but I am pressed for time and I will continue with more latter.

    See post #21, on page 3, for next installment
