Hey,
If I want my project to have a on and off switch, can I put a simple 2 wires switch on ONE of the AC current? -
Hi,
I would really like to know how those axis are working... because, there is only two wires, and I can't figure it out ??? ::) -
Or with a screw driver like I did :P
-
Errmm... strange, I just remarked that it's only when I'm listening music with Winamp, when I play a game, like Dance Dance Revolution for example ::) I do not hear those sounds... With Windows Media Player, I hear them, but they are not as loud as in Winamp.
-
Me say, anything... at least that it does the job ::) I only have a cheap Mastercraft that costed me around 60$ and it's really great.
-
Ok thanks :P And, with that part: "3.5 what? Potatoes? Eat them." you REALLY scared me :| My math teacher is always saying that!
-
Ok... but what happens if my computer AND my amplifier has both some 3.5 input and output?
-
Its a STK4171 if you need more info check out this post:
http://www.electronics-lab.com/forum/index.php?topic=4901.0
And if its really a -VDC, what do I need to do that? Is is a special regulator or something like that? -
Errmmm... yeah, why do you need RPGs anyway?
-
Hi,
I got some chip that is marked -VDC and a +VDC... of course, but how do i do that -VDC do I only use the ground of my power supply, like my power supply is build up that way >transformer>bridge>capacitor and on that capacitor I got a + and a -, well, do I plug those two wires on the chip?
Sorry for my "noobish" stage but we all went in that stage one day ^_^ -
Did you use shielded audio cables for the amp's inputs?
How do you do that? It's just a wire that I made my self, you know, 3 wires, plugged into my computer... -
Filter? lol
-
Geez, I got an amplifier (well 2 of them) and each time someone in the house open the TV or the light, my speakers does a *PACK* in them... the amps are from some Altec Lansing ACS90 speakers... I took the board off and modified it a little bit, but it was doing that before i modified it.
Someone knows why??? -
RPGs that you know of
that are available in
North America.
Secret of Mana, one of the best ever... well personally... -
Don't know what you mean 10 & 13 is output not ground.
Errmmm... you know, in audio you always have 3 (4) wires (when its stereo) well the third one, is it the GND?
BTW: Is 42VDC is enough for this chip...
Another BTW: The 2 channels INPUT, what happens if I put the - on the + and the + on the -? (In other words, if I inverse them...)
Another BTW2: Yeah, does someone wants to explain or have somekind of tutorial on the Compensation thing...? I know one meaning of that word, something that is given for a loss or damage...
Another BTW3: What is the muting and how does it works? -
Pinout STK4171
Pin 1: Left channel input (-)
Pin 2: Left channel input (+)
Pin 3: Compensation
Pin 4: Compensation
Pin 5: Compensation
Pin 6: Muting
Pin 7: Compensation
Pin 8: Compensation
Pin 9: -Vcc
Pin 10: Left channel Output
Pin 11: +Vcc
Pin 12: Bypass
Pin 13: Right channel output
Pin 14: -Vcc
Pin 15: Compensation
Pin 16: Gnd
Pin 17: Right channel input (+)
Pin 18: Right channel input (-)
Eh eh thanks alot! But, what is compensation... and for the second output of the channels, it's the ground right? And... why is there two -Vcc -
Help me a little bit... but what I would like is the Pin-outs... :P Like what is the pin 1, 2, 3 etc.
-
Yeah, what I would like to know is that what the pins are for... like you said Pin 12: Out Left.
And yeah, its something I want to build. -
Yeah, but, am I suppose to understand that pin out :-\ Is it the application I need to check? Sorry, kinda noob here ::)
-
Hi,
Does someone have the pin-out for the STK4171??? -
Clip a power resistor across it. A big capacitor would eat a chunk out of a screwdriver blade. ;D
Lol... I just took my screwdriver :P it's not a big capacitor, it's a 2200uF 35v. -
Yup,
I just made the experience of capacitors... geez, they can hold theirs charges for a long time!
So, is there anyway to discharge them? -
Hi LegendBreath,
Turn off the TV next time you record. I hear lotsa stuff going-on on your recording.
I can identify the sounds from most things, but I wonder where the flute playing comes from.
Audio equipment needs shielded audio cables to avoid interference like you have, and the transformer might also need a shield.
Instead of running the wires from a wall to the phone, try connecting the capacitors to the red and green wires in the phone's jack. A phone line is about 52VDC when not in use so use capacitors rated for at least 63V. ;D
Lol the TV and flute... probably from the girl I was speaking with :P
I'll try alone to see what it does...
And what the... me, swearing in background???
Thanks alot :D -
Hi LegendBreath,
You project isn't crappy, but your transformer might be.
What is the voltage at the input to the regulator without a load?
If you have three 47 ohm/1W resistors, connect them in parallel across the output of the regulator as a load, then measure the input and output DC voltage of the regulator. Don't leave them connected too long or they will get hot and the transformer might get hot too.
Ok thanks audioguru,
I'll try to find some 47 ohm resistors. And, without the load it is 7VAC and 12VAC.
A button pressed and the computer receive the signal?

Hey,
Is there anyway that I can use the parallel port so that I can press a button and the computer received the signal that the button was pressed? Or is there any other way than the parallel port?
