8 Channel USB sound device for LaserBoy

[James Lehman]

Check this out! I just got two of these today! It is a CM6206 chip; which is a second generation to the C106L that is on the other USB sound device.

It has a full sized USB input port. That's nice!

I still don't have this one all figured out yet. Whe I measure the idel voltage on the outputs before the decoupling caps, I get about 1.25VDC. That's only half of what I should get. Maybe I should work with it like a sound card first, before I go hacking it! It has push buttons on it for external volume. That might be something to have to work around.

you finally got it in?

geez! well keep us updated on it!


also im pming you right now!

Yep.. See those surface mount caps and resistors after the decoupling caps. I bet their there to eliminate white noise AKA, hiss at idle. I'd suggest removing the electrolytic caps and bypassing that portion of the circuit all together. That's my opinion, I maybe wrong, I'd have to look at the traces to be sure.

Well... I got two for a reason!

I'm off to bed now, but I'm going to jump all over it tomorrow.

BTW I am one of the featured artists in a thing called 5² (Five Squared). It is a gathering of 25 artists from the community I live in. Every artist was chosen for a different medium. The piece I will be recognized for is...............................................

LaserBoy !!!

Now it's official. LaserBoy is f**king art man!

Cool, this is a lot easier than soldering onto the 2 extra pins of the 6 channel card, for those who want 8 channel. Hopefully the data isn't processed on its way to the card as well!

[James Lehman]

I have an 8 channel USB DAC !!!

YEAH !!!!



DrLava figured out that this card runs off of 3.3 VDC, not 5. So the offset is less and the output is too.

So I modified my original prototype once again and made it work.

Nice! Do you have plans for X/Y/R/G/B/V/I/? outputs from laserboy or something else?

More like X, Y, R, G, B, I, AUDIO_L, AUDIO_R !!!!

This device will be able to play back ALL eight channels of an ADAT show that has been transcribed to hard drive or DVDR.

how about x/y/r/g/b/dmx/Laudio/Raudio

pangolin did it with the cadamod

Hmmm, I have a portable DVR that has surround out, I wonder if I can put my 8 channel waves on that & play back though. Would make for a nice portable controller for laser boy
