Actual wiring diagram

Broken pages. Look at the doggies!

fixed!

I bought the uxcell amp and got it in the mail yesterday. I'll be testing and posting my results tomorrow. I'm in finals right now, but going to take a break tomorrow and get something done on the GBZ.

[mention]Kilren[/mention]good reason to take a break!!!

just FYI, I did NOT do mono with mine. I did L and R wires going to my wheel. Hopefully you get it working and can figure out my problem. If you have time, please put together a little diagram of what you have if you get it working of course.

Yeah, I am doing stereo as well. I'll definitely get you hooked up, at least with where I am at by tomorrow. I'm hoping to have a finished system though, I was really close when I had to put it down for a couple of days.

Does any one have the wiring without using complex usb sound cards etc...?
I just need the volume wheel + adafruit mono amp + speaker + headphone.

You may have to wait for wermy's video. I am pretty sure that is what he is doing.

Looking at your picture and looking at your diagram, I am not seeing where you soldered both AMP GRD to the Switch B on the headphone jack? Also I do not see your USB Sound Card GRD either?

Now with labels! See if this helps...

Is there and reason you used LIN (left channel on the amp) instead of RIN? I used RIN which is why I ask to make sure that doesn't matter in my connection.

Nope, just picked one. I'd really rather send in both signals and let the amp return a mono signal if possible...I've noticed that in some games where the sound pans left to right I'm missing half of it. I saw someone wire up both left and right to the Adafruit mono amp (using both the A+ and A- inputs) so I'm going to try that and see what happens.

I think I might have found my issue. After looking at your last post, I noticed on the GB Wheel you had your first connection going to L on the sound card. I saw this from someone else and it looks like it is backward for R and L.

I think the way it should be is
5 = L in
4 = R in
3 = R out
2 = L out
1 = GRD

Question though, why not ground the GB Wheel to the ground on the headphone jack?

Well, you should be able to swap L and R without any problems, as long as you swap both 5 and 2, and 4 and 3. 2 is the output from 5 and 3 is the output from 4.

So if you leave off the ground it acts like a "rheostat" instead of a potentiometer. Even after reading this I'm not sure I fully understand the difference: http://electronics.stackexchange.com/qu ... a-rheostat

But when I was using my voltage meter to figure out how to wire up the volume knob I saw the resistance range from about 20 ohms to 9.5k ohms between 5 and 2. That gives a pretty wide range for volume so that's what I did.

If you hook up the ground wire I think the range wasn't as wide...but I wouldn't swear to that: I'm not an electrical engineer, maybe someone else can explain the difference!
