Cheap and simple goggle


Marek Rokowski known earlier as producer of EPP models also for FPV (eg. Ursus) ask me for test his new product: cheap goggles.

Simple idea first time in (just) ready made product.
Photos worth more then 1000 words:

















Goggles are made from black plastic.
Inside is 3.5" lcd display.
Weight: 200g
IMHO in comparison to Fatshark the screen is bigger and they are more comfortable in use.
And the most important thing (for me): You can use it with glasses.
Marek sell it as easy to assembly kit with lcd or without
Currently he use this one: http://www.ebay.com/itm/3-5-Digital-...item257f7d134f

Assembly movie: https://www.youtube.com/watch?list=U...&v=fetXd5wQ8co

Interesting idea. Anybody done an actual review?

Unit is 54€ plus 9€ shipping comes to 63€ or $87 USD, plus $17 for the monitor is $104. If you want to cheap out on FatSharks, eBay is full of video glasses that look like a pair of sunglasses for $87 complete and shipped. I'd want the resolution and experience to really wow me.

Thanks for this product!
These HMD looks like its well thought out....I like it!
These are great for bi-focal users and convient for passer-by's, pedestrians.

I'm glad you guys made this, because I was seriously looking at these.
The monitor is just a bit bigger and they are LED's, 60 degree FOV.

Got one of this. For me, they're just better.

Why? Many points, for example weight. Complete Marek's solution is 200g, FatSharks has 216g with cables and 110g naked. Trimersions has 544g - yap, it's real helmet indeed



They have bigger field of view comparing to these two, and if u need to have glasses there is no problem to put them inside. Big foam around the whole will mask all of the sun.

Also because of the only one LCD monitor inside, there is no problem with stereoscopy. When I'm using FatSharks - for the few seconds after wearing I've always two different images. And when flight is finished I need to blink few times to have normal vision
When using Trimersions haven't got this issue, but you know, have you tried to put it on fast?



For the testing purposes, having Marek's goggle it is enough to look inside like on the normal small TV, you don't need to wear it up. Also there is no problem with distortion in the corners of the screen all visible screen is readable. So, changing paramateres through OSD is now simplier.



Power consumption. Producer of the LCD screen says that the power consumption is 44mA, my Turnigy wattometer says 0mA but anyway comparing to 250mA for FatSharks they're super duper economic green and almost BIO solution




At the end I would like to add one plus for the Trimersions. They've better advertisement:

Is there Audio (Sound) through those 3.5" monitors you guys are using?
Audio is important for me with viewing monitor.

No, there is no sound in LCD. You need to use headspeakers for example.

Thanks for response,
so there is a univeral 3.5mm Port for our headphones for audio?

The Title should be changed on this thread,

I think you'll find that the only way to bring sound in is either via a lead from your ground station or by attaching the vrx etc to the goggles to make them self contained.
This is what I had to do with the "flyingwings d.i.y goggles kit which uses the same screen

I'm sorry for the not so clear answer Goggles are based on LCD from the ebay. They're 3 input cables:
- RCA white - video input 1
- RCA yellow - video input 2
- red socket - power supply 12V
There're 2 RCA's because this LCD is able to switch the video between 2 inputs. We're using just one of these two. But you can connect second video source. If you do this LCD will show only the active video source. If both are active - will show video from the priority input, also there is a trick to switch to the second source even if primary is still active.

There is no sound. No port, nothing. So if you would like to hear something - you need to connect directly to the video receiver - audio port.

Hi Krall, does this screen go to blue screen or black with loss of signal? I asked one seller, but got an inconclusive anwser, and it looks to be the same as the one you have a link to.

Is there an English version of Marek's page? It's Ok I figured out how to translate the page

Heppy, they all go blue/black screen the only way ive found to kinda get around the blue screen is to hook my DVR ahead of the goggle ( i made my own) it will go through static for a bit before it goes blue screen but when signal is regained it comes back pretty quick.

RMRC 5" has 16:9 screen ratio, most fpv equipment has 4:3. How it will look? It adds black bars or distorts the image?
