Eachine EV800 Goggles DVR Mod 🛠✔👍🙄

[@maartenzeeful]

Dear Albert Kim, nice tutorial, looked all over the internet for the wiring. Also watched your footage, looks fine to me. I have the eachine VR 2D pro, witch has the same dvd recorder build in. I was looking for a way to get audio out to a microphone. Seeing this it should be a simple fix, connect to the audio of the receiver and the ground. With your research this would be the thirst from the right being the ground and the third from the right the audio. Will try, thanks for posting!

[@john1945xxxxxx]

Albert, getting hot melt glue off of anything is VERY easy. Put a few drops of ethyl alcohol (hardware store denatured alcohol) on the glue and it will let loose of whatever it is stuck to. I tried it and it works great. It doesn't cause it to get sticky or dissolve it, it just breaks the bond. Thanks for all your helpful videos. I have seen most of them.

[@creativeguy1138]

Out of all the videos I've seen of people doing this, you are the only one that has used a step up regulator. I wonder if other people had issues without it.

[@drwald9090]

they don´t ;-) - the ProDVR works internaly with 3.3-3.7v just like the most MC stuff. Putting in a step up - will drain your battery and the ProDVRs internal voltage regulator steps the 5v down again to 3.3-3.7v.

[@michaelsimi2397]

This is way cool! You are a freaking amazing the way you figured out where to connect the wires. These items will be in my next Banggood order for sure! From reading comments below, it sounds like the power converter is not needed, GreaT

[@DavidRodriguez-vt3pl]

Hi. Sorry for my English. Excellent video to connect a video output in the EV800. I could say if you can connect to that screen video input? Thank you.

[@robertanderson3058]

Hi Albert, Well I did it. Few mistakes but finally results.On the back of the board you can cut the trace and use your output on the other side of the trace.After pulling the cover off the receiver and tracing the video I found which trace to cut . I will send a picture of which trace it is so no one else will have to pull the cover off. And all you would have to do is cut the trace solder your output wire from the dvr to the other side .All the other wires stay the same. 5 min job.For sound just leave it really don't need it for the goggles playback.

[@AlbertKimTV]

+Robert Anderson Cool... How's the latency?

[@robertanderson3058]

Not noticeable.I would think there would be some but can't see it.Trying to add pictures but my phone is not cooperating .At&T is giving me fits with pictures sometimes they work sometimes they don't.Basically its the long trace on the bottom right corner behind the receiver. You can ohm it to the top output video second from the right. I went up about half inch ascribed the line to open it and soldered the output dvr above the break. Thats it.

[@AlbertKimTV]

+Robert Anderson cool. You should make a video and share this discovery!

[@robertanderson3058]

I have a picture so how do I send it to you reply or comment doesn't let me add pictures

[@AlbertKimTV]

+Robert Anderson hmmm, I dont know sorry

[@MrMrdamon1]

I did the dvr mod and my battery refuse to accept any charge. I'm gonna try your regulator mod insted of going the 2s battery. Hope it works.

[@AlbertKimTV]

The battery on the inside is a 1S.

[@seamusmjollnir9848]

well they just started to smoke. i now have no goggles. i am not a noob but... i will not recomend this anymore. glad it worked for yours. i got a few days of awesome flying at least

[@JohnJaggerJack]

Can i just power the whole board with clean 5V from a Boost converter? And then splice the DVR into the board? Cheers.

[@Reflexalzheimer]

Albert, can you tell me more about the Pololu converter ? You show us the Pololu S7V7F5 2119 but use another one ... i want to use the same like you in the yellow shrink tube ! TY Regards

[@AlbertKimTV]

+Nooky I've since learned the Polulu is not necessary as the DVR is able to run on 3.7v-5v.

[@befreestudios]

+marblekit I'm going to attempt this mod soon... is it true that a step-up is not necessary? If you do not use one, is there still video noise? Thanks!

[@AlbertKimTV]

+befreestudios I have been told other people tried this but I don't know how they didn't get video noise. I haven't tested that setup myself

[@batcavefpv5007]

Is the video pad same on the 800D? I simply want video out. Thanks!!

[@brianm6060]

Is there a video showing the result and footage? Am interested to see your results.

[@AlbertKimTV]

Here it is - kzbin.info/www/bejne/bqPNYoduiKh6n9k

[@robertanderson3058]

Great Video. Would it also be possible to run the sound and video straight out of the receiver to the dvr and then the output of the dvr back to the board where the rec out was. Then you could see the menu of the dvr and also play back on the goggles.

[@AlbertKimTV]

+Robert Anderson No you would get a feedback loop.

[@dazza9360]

Hi Albert, Does wiring up the dvr in this manner add latencey? or is there a better DVR wiring method you have come across since doing this vid? Many thanks in advance for any advice you can give.

[@AlbertKimTV]

+Dazza no latency.

[@fratetrain4207]

Could you use a separate battery and connect all the grounds to that new battery?

[@fotoamgamgfoto3695]

on the LD5800D there is a 5V regulator already at the screen driver, isn't it part of this board also? if not to reduce video noise you could use a cheap liner regulator IC instead of a stepper.

[@AlbertKimTV]

+FotoAmg AmgFoto I don't know

[@silbay]

So what linear voltage regulator can step voltage up? Oh yeah none. If you feed a higher voltage (7.4 or greater) than sure use an old school lm305 with a heat sink and melt the plastic of the goggles with the waste heat.

[@AlbertKimTV]

The Polulu (link in description) does step up the 1S voltage to 5V

[@fotoamgamgfoto3695]

I thought that the google runs from 2s so 7.4V battery as other googles sorry. If it has 1S that there should be already a step-up to run the LCD etc.

[@xnavigator1]

That's an excellent mod! Great work, do you know if I can use these with my jj, pro 200?

[@pablofpv]

Really good video and easy to follow. I have done the same MOD to my EV800 ,a problem I found was the video would just chop and cut ,go black. I found the cause to be DWRDR (wide dynamic range) setting (on) my RunCam Swift .switched off no problem clean and clear screen. My set up is pal 50hz ,did not make any difference if using internal battery, step up or separate 1s lipo on dvr? I have not had time to try this with another CCD or CMOs board camera, I just thought if you or any else has had this issue?

[@AlbertKimTV]

+pablo no, havent had that problem.

[@navarojimuralitharan7545]

Does the AV in still works with DVR on?

[@NaftulyART]

Thanks , can you also solder dvr to the "eachine one " ?? And can you connect the dvr to video in in them to see what you recording?? - hope to hear from you soon

[@AlbertKimTV]

+Naftuly Erenfeld hi. Sorry, I don't have the Eachine One.

[@NaftulyART]

+Albert Kim (marblekit) ok thanks Albert kim

[@AversusB]

I did the mod in your video! Awesome tutorial. I do have a question. How do you get to the DVR menu when it's all installed? I tried to follow the instructions that came with the DVR but no menu pops up on the screen.

[@AlbertKimTV]

+AversusB not possible because there's no switch for an additional AV output.

[@JohnJaggerJack]

Can i use an LM805 5 volt voltage regulator?

[@seamusmjollnir9848]

Hi, i love this mod. just did it but when i play the video back half of the footage is black screen. i checked everything and all joints as well and it all looks good. the video on my goggles is solid for the whole flight but not from the dvr. any ideas on what i can look at? i love it so much and would hate to have to take it off. Thanks.

[@RobStumvoll]

hi albert, thx for the great video! i do have a slight issue: when recording a video and the taking the sd card into the computer, the file is not watchable = no video playing, any suggestions what this might be? thx!

[@AlbertKimTV]

Your card may be corrupted and needs to be formatted. It could also be too slow. Get a better microSD card.

[@RobStumvoll]

Albert Kim i was thinking the same, but the funny/strange thing is that some videos (from the same goggles and dvr) are being watched without any problem

[@RobStumvoll]

hi albert, just wanted to say that i fixed the problem by formatting the card again :) now my next problem is that when i record a video the frame rate while flying is super low,... but im sure i can find a solution to that online :) thx again albert and keep up the good work!

[@sabeamixtades6658]

I have someine v009, but the receiver electronics is different, how can I know which pins are the signal and which are the audio, positive and negative for these glasses? Thanks bro!!

[@AlbertKimTV]

+Sabe Amixtades use a multi meter

[@sabeamixtades6658]

is possible know the video and audio with multi meter?? thanks

[@AlbertKimTV]

+Sabe Amixtades video voltage will fluctuate with the signal. Send a signal with just video and check

[@sabeamixtades6658]

ok thank you so much Albert!!! ;)

[@Josh_8300]

This is a pretty awesome mod video. Two questions..... 1- Is it possible to mod this into diversity? 2- Is there enough room inside to put a bigger 1s battery or a 2s with a stepdown?

[@AlbertKimTV]

Thanks! 1. Diversity not likely. The receiver is hardwired into the board. Only way is if they came out with a board with two receivers and a diversity switcher. 2. Yes, there's a little bit more room but not that much. You'll need to get something that fits that space pretty perfectly.

[@Josh_8300]

Holy mother.... That was 5yrs ago Krowtow...

[@DimplePoji]

so tempted to do on my skyzone v2

[@toshatappermakeuptutorials2869]

So I have the Spetrum goggles and want to do the eachine dvr mod on them. When I opened it up it looked the same but am a bit confused about the 5v. The eachine Pro dvr comes with the seperate +5v can I use that?

[@DanielJLopes]

Very nice, are you able to record in PAL? Or is that NSTC?

[@AlbertKimTV]

+Daniel Lopes I am able to record in PAL but the bottom of the image is cropped. This is a known issue with this product but is not a problem for me as I don't have any PAL cameras

[@ariehartansah4206]

hi.. is there any way to replay the recorded footage to the ev800 itself? thankz

[@stofffpv3128]

Hi wanna do this mod on my vr100s how would i know which pins to solder to, for the playback thru the goggles..which is the most annoying..as the cables go across to the left hand side of the goggles and they use the nasty phon type plug..thanks

[@AlbertKimTV]

I did it using a multimeter and a little knowledge about electronics. With this you can usually figure out how a lot of stuff is put together with almost no documentation.

[@bajaace7970]

Albert Kim so how specifically did you figure out what the audio and video outputs from the receiver pins were with a dc meeter... power and ground im sure i will be able to confirm on my specific receiver but audio and video i don't know anything about

[@ivanczar]

Does the cable come with the dvr?

[@AlbertKimTV]

Yes

[@joey48442]

Any idea how to change the DVR settings? Thanks!

[@AlbertKimTV]

+Joey Blatchford Yes. You do it through the video out connection. I didnt have a monitor that was compatible. Youll need to use one that is compatible to get the DVR settings menu.

[@joey48442]

Albert Kim ah, so you can't do it with the eachine ev800?

[@AlbertKimTV]

I didn't try it. I tried it with a couple different monitors when I was doing the setup and I could not get them to work with this DVR. I decided at that point I didn't care about the DVR settings and just went with the defaults so I didn't bother to hook up the video out... I'm not sure how I would set it up on this goggle anyway...

[@GEOFROGGYCOM]

Do I mandatorily need to use the voltage regulator? Thanks!

[@AlbertKimTV]

+Jose Ramon I've heard other people able to do this mod without the regulator.

[@MrMrdamon1]

I added the dvr and my battery refuse to charge, no light on screen at all.

[@simonwallace699]

Great video Albert

[@AlbertKimTV]

thanks!

[@mortache]

can you tell me which one is the rssi pin? does the receiver even have one?

[@AlbertKimTV]

Sorry, don't know.

[@villadseskesen]

What if you don't want to pop out the led?

[@Soldier1287]

what if you instead soldered on a rpsma coax cable to attach a 2nd antenna? possible doubled range mod?

[@Soldier1287]

and drill a hole in the housing

[@NaftulyART]

hi albert . I want to say that you really do not need the pololu - Today I connected directly and its works well also with Battery 7.2

[@AlbertKimTV]

+Naftuly Erenfeld yes, thanks

[@techvirus9541]

Which is better eachine vr006 or eachine ev800???

[@AlbertKimTV]

Get the EV800D's... the EV800's are outdated now.

[@polarbearjf]

Hey Albert, So just ran this mod on my Ev800s and the unit powers up and the screen from the Goggles also powers up, power is running to the fpv cam but dont seem to be picking up a signal.....any ideas?

[@AlbertKimTV]

It's possible something might have gotten damaged in the receiver? It could be almost anything, so can't really say for sure.

[@jjooyycc33]

did it work without step up voltage becose I see few vids without and it works but today I recive it and it dont work :D so mayby not enough of voltage ?

[@AlbertKimTV]

+ondřej župka I've heard some people having success and others not.

[@jjooyycc33]

now I have succes before I have conected only output from glasses so I wasnt able to see menu without input too glasses .D and also video dont record becose card wasnt formated :D

[@naorhazan7470]

Do you know if it's the same video resiver like Eachine 007 resiver?

[@AlbertKimTV]

Not sure. It's probably similar since they're both Eachine brand.

[@DonAlvaro14]

Where can I buy the step up??

[@AlbertKimTV]

It may not be needed. Others were able to run off 3.7v.

[@DonAlvaro14]

Albert Kim Thanks!!

[@jarecdiver]

hows the battery life after the install?

[@AlbertKimTV]

Seems a little less, but I've never had it die on me while flying. The only issue is the battery level meter is worthless. It pretty much drops to zero as soon as you take it off the charger. My estimate is an hour to 1.5 hours. I also always turn my goggles off in between flights.

[@jarec007]

+Albert Kim (marblekit) thanks my battery charge indicator seems to be working fine but I haven't flow. with it much. thanks for the video and the quick response. I'm new to the hobby and am excited to see where this goes. goggles seem to be nice. I had to add glasses to mine because my vision isn't good close up. but that was an easy mod.

[@CurtisBHertz]

It'd be awesome if you showed some dvr footage. :)

[@AlbertKimTV]

+Curtis .B Hertz okay... it looks just like any other DVR footage I took with the mini DVR previously but I'll upload some the next time I fly.

[@AlbertKimTV]

I will do a side=by-side comparison video of DVR footage from this setup and my Fatshark Dominator V3 DVR in a future video.

[@CurtisBHertz]

+Albert Kim (marblekit) That sounds fantastic!

[@oooooooo2348]

what voltage regulator did you used?

[@AlbertKimTV]

+oo oo oo oo used a pololu. Link in description

[@MicheleLagorio]

Ciao Non e possibile fare un Video input ? Vorrei usare con un cavo con orginale Hubsban Transmitter . Hubsan transmitter che Video output . It is not possible to do a video input? I would use a cable hubs H501 S Transmitter. Hubsan Transmitter has a video output.

[@AlbertKimTV]

+Michele Lagorio I don't think so on this google

[@Benny71]

Nice ,cool mod :)

[@jamesmanderson5311]

bro you have some awesome mods. going on thanks

[@AlbertKimTV]

Thanks!

[@jamesmanderson5311]

i have got a question i dont have to good of reception or distance on my ev800 i bought a pair of those 6 dollar mushroom antennas and they didnt do no good . i am pretty knew at this so i have been asking alot of question. so my question is what do you think about the tbs ibcrazy antennas, and you think it they will make me have a better distance and veiw

[@Fast1Guy]

Other users of this DVR have found it actually runs better and cooler on a 3.7v single cell LiPo. This was reported by several on RC Groups.

[@AlbertKimTV]

Yeah, I learned of this fact after I made this video. It's working fine for me so I'm gonna just leave it alone for now unless I need the Pololu for some other project, then I'll scavenge it out of the goggles :)

[@yayathidayat6678]

I did it. Thanks

[@a.e.m.i.productions]

Thank you, so I will connect the wires directly to the goggles board ..

[@victormanuelsaorin1686]

Hola Sirve este www.dx.com/es/p/mini-dc-dc-adjustable-voltage-regulator-module-blue-151211#.V9KM6vCLTcs But if the exit is 5v do you really need the pololu?

[@Naralex]

There are people who are on the video input, tell me where he is? I'd like to connect it to the wee eachine pro dvr so that you can immediately on the helmet and view. Thanks in advance. (Google translation)

[@danknee]

im about to install the prodvr on to a kds kylin. Did you just use trial and error to find out which was video and ground? I used a multimeter to find out which is +/- as well as voltages of the +. here is a link to a pic for reference: www.rcgroups.com/forums/showpost.php?p=35262150&postcount=319 Im guessing the .48 and 1.14V are the audio and ground... does this sound right to you?

[@AlbertKimTV]

+dqDronz I tuned it to a vTX transmitting a video and audio signal. When the receiver gets a signal you see the voltages move around for those two. The others did not move around. I had to guess that video would be next to power and I turned out to be right. I assumed this because a lot of other receivers are similarly configured.

Thanks. Like you, I was only able to get the DVR function working. The osd menu doesnt show up when holding the menu button. Could it be the that we need to solder more wires? I'm only using 3 wires. Video a red and a black
