Any electrical engineering buffs on tonight? I'm new to electronics and I'm currently working on an exploratory project: making a battery tester using a ИB-15 lamp that I found with some scrap electronics (pic related). The only info that I've been able to find on it so far is this page: http://www.radiomuseum.org/tubes/tube_iv-15.html. But being new, I can't make any sense of how to actually get the tube to light up
apply electricity to the lamp

Another pic of the tube

Plug it into a wall socket, something will light
Bumping for a legit answer
whyd you post the lamp name in cyrillic letters?
anon, are you russian?
>>51551202
Cuz it's the name of the tube
>>51550799
You are going to need 12v DC and probably 5v DC, yes at the same time in two circuits. Not practical for what you are trying to do.
>>51551321
I understand that it's not the best thing for me to do, but like I said, this is mostly just exploratory. The main thing I'm trying to figure out is how to actually use the tube at all, not just with a battery tester. What voltage on which pins? Which pin is ground?
>>51551355
There is no ground, the pins that go to the coil are 12 I think and the other are 5. I would start very low just in case I am full of shit
>>51551355
well the shorter pin would be the negative one and the longer one is the positive. im amusing that the other two are an enable pin and the ground for the enable.
So probably you have to have like 5V to the negative and a resistor so it doesn't instantly pop, and then have the ground grounded for both grounds, and then you probably also have to put the enable wire on some volts too, probably also 5 for it to actually come on.
also im not like a techie or a engineer or anything i dont really know for sure im just kind of browsing but since no one else has really answered yet..

What I've gathered so far is 12v on pin A, 5v on pin G, and according to the website in OP, .6-.9v on f+

>ИB-15
EE student here. I just recently started researching tubes for a class project. If your new to electronics in general I have to advise you that tubes are about the worst place to start. I'm trying to find the datasheet for that particular tube you're using but so far haven't had any luck. I really can't tell you anything about it without the datasheet. If I find it I'll let you know.
>>51551510
This website has the datasheet in russian
http://tubes-store.com/product_info.php?cPath=44&products_id=673
Impossible to find english verson
>>51551534
>>51551510
And this is the datasheet to the american equivalent of the ИB-15, but it's not the same tube

>>51551573
Do you have access to a multimeter?
>>51551620
No. What's a multimeter? If that's something for drugs, I don't want any part in it. Sorry dude.
>>51551620
Yes, I do
>>51551665
LMFAO
pic related.
I was about to suggest you ask /diy/ for help but I see you've already started a thread there. You can probably get better advice from /diy/ than what I was going to give you. Good luck!
>>51551688
I do believe I have been trolled.
Anyways, check the resistance between pins 2 and 3.
>>51551705
/diy/ is super slow compared to this board, and I can use all the info I can get.
>>51551705
Cheap brand multimeter says 150Ω
>>51551836
150kΩ
I'm an EE. Currently working on a nixie tube clock.
You need to apply a bit of voltage on the filament to get the lamp hot (this is the way vacuum tubes work)
You then apply 10 to 50 volts on the anode (I think pin 5). apply 0 volts on pin 1 to turn off, 5 volts to turn on.
>>51551836
Plugging the minimum voltage (.6) directly into the filament is going to exceed the max current (.001) listed by the Russian website you gave me. .6 V will give you 4 mA. I'm inclined to believe the max current stated by the website is incorrect. If it's not you're going to need tome technical wizardry to get the filament current in check that I just can't get in to at 3 in the morning. I can take a look at it tomorrow probably. In the meantime, have a wallpaper.
Also those lamps chew through a crapload of power so I don't think making a battery powered gadget is a good idea/feasible idea.
>>51551906
That k makes a big difference. .6 V going to the filament will be fine.
>>51551929
Listen to this guy.
>>51551964
No way in hell a lamp filament has 150kohms, are you shitting me
Do the measurement correctly OP. And also pretty sure 6Vrms into the filament would work. IIRC that's the "standard" lamp voltage.
>>51551987
If I had 4 hands to take a pictures of my multimeter I would, but the reading I got was indicated by this picture: >>51551836
>>51551987
4 uA does seem kinda low to make anything heat up. I wouldn't say it's impossible but it did strike me as odd.
>>51551999
That doesn't sound right...
>>51552022
Yeah, that filament is supposed to get pretty darn toasty
How big is this tube OP? Give me a similar sized object.
>>51552052
>>51552113
christ, fuck off with that shit
>>51551381
>There is no ground, the pins that go to the coil are 12 I think and the other are 5
that makes no goddamn sense
you need to have a referent zero
>>51552147
No
>>51552113
Even smaller than I expected. That explains the 4 uA although it still seems low. I'm trying to make sense of the other pins.
>>51552196
Ight man, I really appreciate all the help I'm getting. I've been trying to figure this out for a week
>>51552224
I'll take another look at it tomorrow. I gotta get some sleep.
>>51552188
> just in case I am full of shit
>>51551940
Did some googling, seems 0.6-0.6V filament voltage and ~150 ohms are correct.
Anode (centre pin) should have series resistor for protection, 3.3K or higher. 20+ volts
Grid doesn't need any resistor, just apply voltage.

>>51551381
He is right, I am sorry. I was thinking of this
