So, I bought gen 1 ir polish tanker nightvision goggles online.
When I touch the power connector to a 9 volt battery, the pack on he back buzzes, but I cannot see anything through the goggles, just black. I have:
1) made sure the helmet is set to 12vdc, not 24vdc.
2) goggle covers were removed.
3) I have not powered them up in daylight, just a darkened room in my basement.
4) I used a flashlight and the ir headlight covers to create ambient ir light.
Did I buy a bum pair or do I need the 12 volts before they'll power up green? I dont know anything about night vision goggles, should I be able to see through them anyways without power?
Also if anybody knows what the white thing is an what the black paste is for, that'd be cool too.
And this extra connector. I assume it was for the ir spotlight that was not included.

Sounds like you burned out the resistors using 9v instead of 12v, hence the humming.
good job bricking an already useless set of NVG
>hurr, if I plug a 220v appliance into a 110v socket, will it werk???
>>29714168
white thing is a battery. black shit is shoepolish for the leather.
cord is for the extra-fat battery pack for your belt.
im this guy >>29714196
>>29714196
Not wise, but why would i burn out resistors using insufficient voltage?
>>29714216
the better question here is why didnt you pull the battery out of your car to test it instead?
>>29714228
I tried my car battery charger set to 12vdc at 2 amps, and then 10 amps, just a weird clicking sound.
9 volt makes a hum.
When should the goggles glow green?
>>29714326
>I tried my car battery charger
Is this a fuckin troll thread? if you used a battery CHARGER, then you more than likely burnt that bitch out without a doubt. Before I was just messing with you with the 9v smoke detector battery burning it out, but I guess your stupidity really knows no bounds.
Use your car battery, and make sure you disconnect the terminals first before using jumper wires.
>>29714379
>12vdc at 2-10 amps
>implying a car battery doesn't put out 12vdc at a much greater amperage
You sound like the retard here.
>>29714202
>cord is for the extra-fat battery pack for your belt.
Well, that was good information. I was able to lop off the weird ass connector on the end, now I have a whole cord of wire to play with.
I hooked it up to a car acessory charger I had for an old cellphone jammer and tried running the thing through my car's accessory slot.
Same humming, no noticeable difference in the nightvision though. Although I have no idea what voltage that chink shit adapter was raterd for though.
Order a proper 12 volt battery pack and an ir led flashlight to do further testing with.
>>29715018
Where and how much did you buy this for?
they look sick as fuck if they work
>>29715098
https://www.varusteleka.com/en/product/polish-pnw-57-tank-helmet-with-infrared-goggles-surplus/24667
They might not work, as the page suggests. I just read online how easy it was to get them hooked up to a 12v source and am a sucker for novelty hats even if it doesn't work.
>>29715127
did yours come with the IR lamp?
>>29714196
Wrong
Low voltage will be fine
>>29714152
To Answer your question, the Transformer/Energizer on back will buzz when it's on, but you need adequate power (12vdc)
>>29715192
Any idea how many amps? or does it matter?
>>29714152
There is a blade switch under a little screw cover on the bottom of the transformer (box at the back of the helmet. Chances are it's set to 24V, not 12V. Turn the switch and you should be good to go.
>>29715018
>I was able to lop off the weird ass connector on the end
Why the hell would you do that? You've made your job way more difficult than it needed to be now.
>>29715171
No, but it did come with glass covers that are either for the lamp I didnt get or to cover vehicle headligts to.make ir spotlights. So I just ordered an ir led flashlight.
>>29715304
I loped off the connector on the battery pack cord so I didnt have to mess with the cords on the actual nvgs.
And I am almost positive it is set to 12v
>>29715379
Yeah, it's set for 12V. You may need to change a pair of diodes found in the transformer. A replacement pair should be in your transport crate. They're cylindrical and made of plastic.
>>29715474
the white battery type dealies as seen in >>29714168
>>29715482
Yeah, do you have two of them?
>>29715493
Yeah, but I won't change them just yet. I'll wait until I get a proper 12volt battery box and wire that in.
That way I'll eliminate the power source as a problem before troubleshooting the diodes.
>>29715518
You don't want to do that, proper procedure is setting up the unit first, then working on the power source. The unit is polarity-specific, you don't want to wire/solder anything and then have to redo it because you got the polarity wrong.
If you want help with replacing the diodes, I can guide you through it. I've helped many anons with this before.
>>29715555
I get the polarity issue.
But apparently I am not understanding the diode issue.
Right now, the NVGs hum when power is applied, but I do not see a noticeable difference in green glowing. This, to me indicates low voltage.
Once I wire in a proper 12 volt source, and I notice the glowing doesn't increase, I'll troubleshoot the diodes.
THAT BEING SAID, I'll gladly listen how to do it since I might have to in the near future.
I assume you open the metal pack at the back of the hat by removing the 4 screws and swapping the diodes like AA batteries?
>>29715609
>Right now, the NVGs hum when power is applied, but I do not see a noticeable difference in green glowing.
Are the lenses glowing at all? Reading the thread, I thought you were not seeing anything at all, correct me if I'm wrong.
The unit will run on 9-12V, it's not incredibly particular.
>I assume you open the metal pack at the back of the hat by removing the 4 screws and swapping the diodes like AA batteries?
That's more or less how it's done, just be careful while disassembling the unit, one anon fucked up his wiring because he rushed it.
Inside the casing, there is a little triangular hatch cover, underneath which lies the diodes. You must orient the diodes as specified by the hatch cover (the cover should be marked with "A"/"B" to correspond with the "A" and "B" ends of the diodes).
That's about all there is to it, just be sure to take it slow and not to apply excessive force.
>>29715733
Looking through them, there is a greenish tint., and I guess no glowing at all.
I am mixing up the tint and the glow I guess.
Well, give me a minute, I'm going to upload a picture for your opinion
>>29715733
Top right: battery cable spliced to a 9v connector.
Top left: nvg cable.
Bottom: nvgs.
When I connect the battery cable, I get humming.
Does this consist of a sufficient power source an should I notice some glow from the goggles?
>>29715829
And using them in this state, in a darkened living room, I get no glow, and looking at slightly bright things, like limp light from a room down the hall, the nvgs are actually dimmer than my eyes without them, so they musn't be working at all.
>>29715829
The 9V should be giving it enough juice to function properly. Is it a new battery? If not, the unit will not work.
You'll know when the unit is working, the difference is dramatic.
I have to go out for a bit and I won't be able to post for a while, if you have any other questions post them and I'll answer when I return.
>>29715883
>>29715893
Did you try them with the IR flashlight?
>>29715908
No, I don't have one. Ordered one today when online research suggested ambient IR is not sufficient to support the NVGs
>>29715949
maybe the goggles are working and you just need the IR
>>29715966
I tried with a normal flashlight under the ir headlight lenses, no dice.
But give me five minutes, I might have a revelation
>>29715983
Whelp, I tried something basic, like switching 9 volts. I noticed that the humming changed, so, I went back outside to the battery charger, and with an alligator clip attached to either half ot he 9 volt connecter, powered it on at 12vdc.
The humming became a fast tick, and, though there was no noticeable nightvision, I did notice the left eyepeice was flickering slightly, and even blinded me for a split second when it seemed to go full power. The right eyepeice had no change.
The power source is still questionable, but I leaning towards the expert's opinion that the diodes have crapped out, unless the actual googles are damaged in some way.
>>29716230
As a guy who has no idea what all this electrical stuff means could you explain everything you did to get this together. Also what kind of battery and tools you need to complete this.
>>29716265
It is still incomplete, since they are not functional yet.
Pretty much, so far, the NVGs, like all electrical appliances, have a cord. In that cord, is two wires, the positive and the negative. I pretty much cut open the cord, attached 1 cord to the negative side of a 9 volt battery, and the other to the positive side. This caused and electrical humming in the NVGs, but no night vision. I then hooked it up to a car battery charger, which has a negative and positive wires, capable of putting out the 12volts DC required to make the goggles work. They still didn't work, but they made more noise and flashed slightly.
The next logical step would be to change the diodes as suggested by NVG Guy, but I'll wait to see if he has any commentary on what I just did with the battery charger, and since I want to wait until amazon sends me a proper 12 volt battery to wire into the nvgs.
>>29714196
>>29714379
do you just sit around lurking and insult everyone who asks questions? Is that what your parents did to you? fuck, man.
>>29716265
A couple of oridnary cylindrical 12volt batteries would work right?
>>29716355
meant reply to
>>29716315
>>29716355
I was just hooking up a 9 volt, which NVG Guy suggested was sufficient, but I ordered pic related instead for ease of use. It is a 8xAA battery holder that has an on off switch. Instead of just connecting wires to a 12 volt, I will be able to use AA batteries and have an on off switch.
>>29716373
thanks anon these things are seriously cool
>>29716416
jesus fuck whats going on today
>>29716429
>>29716230
Okay, I'm back. The ticking shows that the transformer is working properly but the flickering in the goggles is not a good sign. I would replace the diodes before messing around with the unit any more to avoid damaging the unit.
>>29716445
Does the amperage make a difference? My battery charger can provide 2, 10, or 50 amps
>>29716463
ALso, is there a trick to opening the transformer? I removed all four screws, and assume it splits open in half, but no dice.
>>29716463
2 is enough
>>29716526
The casing should come apart with little effort, try being a wee bit more forceful.
Diodes swapped. Got a heck of a shock when I took the old ones out. An no, the 9v was not attached.
>>29716713
>Got a heck of a shock when I took the old ones out.
That's weird as fuck, I've never heard of anything like that ever happening before, I wonder what could have caused it
Make sure those metal tabs on the ends of the diodes are flattened, otherwise the unit may not work.
>>29716758
Yeah, nah, no dice, situation no change.
Left eye peice flickering a bit, right eye peice nothing.
>>29716992
Might just be the tubes, in which case you're SOL. It sucks but unless you can get new tubes and perform a transplant there's not a whole lot you can do. Such is life.
>>29717090
The question is if I cancel my order for the battery case and the ir flashlight in the dim hope that they fix it even though testing has proven they wont't
