Modded EV800 goggles

I know this isn't a quadcopter but want to share as an example of budget yet very functional options for analog goggles. This setup costed $160 dollars Canadian. I couldn't get myself to spend insane amounts of money on analog goggles so I made what I had work!

My original EV800 non diversity goggles now have an AKK diversity module (could use any module you like) as well as video out and a dc5521 connector to power the goggles externally. Internals include a step down 26v max input (2-6s lipo) to power the goggles and a step up 3.3v in 5v out for the receiver module. I completely removed the old receiver because there was no other way to do this properly. It was soldered so that took some finess. A coat of white paint freshened it up as well :)

UPDATE: Flashed achillies and it's so much better with regards to menu and overall speed and ease of switching channels. I haven't been in enough of a multipath prone area to see how much of a difference it made with the receiving quality.

Nice job. Do you have stock receiver pinout? Or whole board layout? I want to repurpose my ages old EV800 with Eachine PRO58 module and some other niceties.

The only way I found the pinout was when I (very carefully) unsoldered the stock receiver board. It is labelled on the back. Keep in mind anything above 3.3 volts at those pads will blow something.

Thanks! I'm sure that stock module will go into bin anyway. Luckily I have good hot air station.

I don't have a hot Air station. It is possible with an iron but yes that sounds much better haha.

I'm looking to do something similar. How did you mount the receiver? Do you have a wiring digram?

The receiver is held by the 3d printed mount. It has a sliding door at the back that closes to hold the module. I had to de-pin the module otherwise it wouldn't have fit so flush. When I de-soldered the original receiver in the ev800 the pads on it were labeled. Googled the diagram for the diversity module and wired accordingly.

Nicely done. They look great, and I imagine the difference in performance is quite significant.

Thanks! Very happy with them. Speaking performance I was out 3km with my DC7 long range quad today at 500mw transmission and video was golden!

Thanks for sharing. This opens up some possiblities i didn't consider before. Let us know if you come up with anything else.

I will!I forgot to mention this whole endeavor set me back no more than 160 dollars Canadian, including the price of the goggles originally.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
