Hello everyone,

I really like my old Fatshark aviators because of the large FOV, but i don't understand why they can make good goggles but in a stupid mask.
I never really liked the fatshark mask, the foam coming off, fogging up when it is cold and i never got it to fit exactly so it is time for a Fatshark "rebuilt"

I talked to Rob about it and he told me he could make a fine mask for me, well he did indeed so here is a build for my Fatshark mask, he is not finished yet but i will keep you updated.

To start.

First you need to take your Fatshark apart, it is not difficult but you have to be a bit carefull.
Take the foam of and turn upside down to remove the two screws

When you take the two parts apart be carefull because they are locked together in the center, i forgot to make a good photo of it.

Next you take the small screw in the center of the print out

Lift the print up carefully and you will find two more screws there

Take them out and carefully take the Kopin unit out, put the screws back in so you don't lose them

http://imageshack.us/a/img853/6219/20130323132331.jpg

Now Carefully turn the Kopin unit upside down and remove the connector that is attached to the board

Put the Fatshark mask back together and if you ever want to sell it in the Original state you can simply put the kopin back in and you will have youre Original back.

Oké, so now we have the Kopin unit we want.

But we need some more because i want 5,8 RX, headtracking and of course video in if i want to be directly wired to my GS.

So here we go
5,8 RX

Headtracking from the arduino diy project on rcgroups, works very well.

Power supply for the RX and Kopin

And of cours Rob's very nice mask.

First get kopin to work, i want the
power for my goggles from my Radio. I have a 3s lipo in there with enough power and since i am going to need a wire from the radio for my headtracker i might as well power it from there but i am going to build an option so i can power it with a seperate 3s lipo.

Let's hook it up and see how it works.

We have static

The right channel and we have a image

http://imageshack.us/a/img202/2226/20130323144323.jpg

I forgot to tell that you have to screw the kopin to a plate in my case some ply which i will make black for final installation.

http://imageshack.us/a/img15/5475/20130323142924.jpg

Now first let's install the 5,8 rx, the advantage of the fatshark is that you can switch it with a 2,4 rx if you like so you can use both

http://imageshack.us/a/img12/7521/20130323162544.jpg

http://imageshack.us/a/img145/1433/20130323162553.jpg

Now i want to be able to switch the rx on and off if i want to use a cable to my GS so there has to come a switch

http://imageshack.us/a/img189/2499/20130323164356.jpg

The power supply for the rx and kopin.

http://imageshack.us/a/img43/2218/20130323171020.jpg

And the last part for tonight the connector for external cable

The story will continue in a couple of days

Oké, part two

First thing that had to come in is my DIY headtracker, i really love flying with a tracker it gives much more feeling and i think it's easyer flying if you can look around and be able to see landmarks without having to turn youre plane.

http://imageshack.us/a/img11/9160/20130323142246.jpg

And here he is inside my mask.

http://imageshack.us/a/img94/8823/20130331135137.jpg

Now i need a cable from my radio to my goggles for power and my headtracker but i want it with a connector so i can use a seperate battery if i want

http://imageshack.us/a/img171/2558/20130331171208.jpg

http://imageshack.us/a/img16/459/20130331183813.jpg

This works very well, the cable needs to be pulled quit hard if you want to get it out

Now i want to be able to switch the tracker on and of so if i am not using it or i need to callibrate i can switch it off. So a second switch is in place.

http://imageshack.us/a/img607/5784/20130331183749.jpg

Now it is time to solder the whole thing together.

http://imageshack.us/a/img545/166/20130331183728.jpg

And finally put the kopin unit in there.

http://imageshack.us/a/img838/356/20130401140212.jpg

The kopin unit is screwd in so if necesary i can take the whole thing apart. The headtracker and bec are both held in place with (velcro it what you call it in english?) we call it klittenband in the Netherlands. The rest is also held in place with screws.

Now this is the final looks

http://imageshack.us/a/img838/9580/20130401140530.jpg

Tested everything here at home, tracker works fine, rx works fine both can be turned on and of, external works so i can plug him direct into my groundstation and best part.
He fits so nicely, there is no way you can compare this with a normal FatShark mask, finetuning on the kopin needs to be done but that is done on the field.

I'll get back as soon as i have been flying and give some results.

Hope more people have use for this build and if you have questions feel free to ask.

Oké, been flying for a while now with my mask and i must say it is a relief.
No more fogging up, no more liners coming off it's perfect for me know, the receiver and the tracker both work great.
Here is a video showing headtracker movement, the video itself has been taken from my groundstation because i don't have a video out on the goggles.
enjoy

Wouldn't a bnc connector work better for video as it will LOCK into place and won't pull out

Addy

I prefer a connector that doesn't lock, When i am hooked up to my groundstation i am Always sitting next to it so no one can walk between me and my groundstation.
And if for some reason someone is going to walk there and pull on the wire i think it is better that it get's pulled out, if you have a connector that is locked you're goggles will be pulled of youre head or he will pull the whole groundstation upside down.

Impressive build!

I am rather surprised though that you didn't just do the standard "Ski Goggle Mod" that so many others have done. Just take the strap off of the Aviators and then mount the entire goggle assembly directly onto a mask. Although your solution is nice looking.

Also, is that Rob from FPVPlastics? It looks like his ski mask setup.

With the standard ski mask mod there is no room for a 5,8 rx and a headtracker and you can't power it from youre radio so i decided to build it completly up from the ground.
This way you can "personalize" it to you're own needs wich in my case is 5,8 and headtracking.
And it is Rob from FPVPlastics that made the mask for me, we talked about it for a while and he made one for me with a flat bottom so there is room to mount stuf.
Hope to resume building tomorrow.

Thanks Addy
Btw you don t ware glasses

You buld this goggle for head tracker
And it s fit better on your head

Hey Rob,

I guess if you put the kopin unit further inside which is very good possible, i had about 3 cm space left you can wear glasses.
I don't know if having the kopin unit close to your eyes is the same as having the unit close to youre glasses, or is there a difference? maybe someone that wears glasses can answer this question.

My purpose was to have a goggle that i could use to build in so with space for headtracker and rx and be a whole lot more comfortable as the Original goggle and that worked fine.
Thanks for making a great mask.

Looking great Addy!!!!!

One Q though, i have the old fatshark base goggels and am thinking about doing the same as you but i would like to know if it is possible to ad a 5.8 module to it, to eventualy end up with the same as you have?

Regards T

Ps: If you rather answer in dutch you can pm me or here or under the same alias (Traveller) on FPVForum.nl

Hi traveller,

If you look close you can see that i added a 5.8 fatshark module on the left side of the mask.
Works great, pinout is actually quit simpel and he works on 5 v from the same bec that gives power to the kopin.
I can turn him on and off so i can use a external source also.

Hallo,

Ich habe die DIY Mask B, ich möchte eine "RV933 V2 Aviator 5,8Ghz" einbauen.

Benötige ich das 5,8Ghz Modul? Ist das nur für die Spannung und als Empfänger da?

Kann ich nur das Kopin verwenden? Welche Spannung benötigt es? Kann man die Helligkeit und Kontrast dann noch verändern?

Hat wer Genaue bilder zum Kopin einbau?

Hi Markus,

The part with the receiver on it also is control for brightness and contrast so if you take it out like i did you don't have control over that.
I only used the kopin which needs 5v that you can get direct from a 5volt ubec.
If you are only planning to use you're goggles with a groundstation i guess you can drop the receiver but when i fly "in the area" i am only using the SPW on my goggles and i don't need to bring a groundstation but that is up to you.
I dropped that part because i am not using 2,4 which was my receiver and i wanted power from my RC Tx since i needed a cable from my Rc Tx because of the headtracker i also used power from my radio so i don't need another seperate battery.

I don't have more fotoos from the build sorry for that but i guess you will figure that out.

Hi Addy,
i am working on doing this exact mod to my old fatshark aviators. I can't see your images anymore...could anyone help me verify the cabling that goes to the kopin module? I was guessing the red, black and yellow were +5v, gnd, and video and the others were for brightness, etc. my multimeter disagrees! Any chance anyone has these pinouts? The kopin website doesn't help much either.

Thanks!

Hello Jason,

Sorry for my late reaction, i'll have to see if i still have the image's.
I will look into it this weekend
