8 Channel USB sound device for LaserBoy
« on: January 25, 2009, 01:40:47 am »
The USB 8 channel card is a +3.3VDC device, so it needs less of a negative voltage offset and more gain.

The 6 channel USB board is +5VDC so it needs a bit more negative voltage offset but less gain.

This version can be set to compensate for just about any sound card.

It also has excellent adjustment accuracy!

AND it features a nice solid, integrated 25 pin laser projector connector!

Love the pretty colors!

The big star is glow-in-the-dark!

It's so I can see where I'm supposed to be when the lights are out!  ::)

I like to play with it and my BluRay laser.  ;D

I found it on the road one day when I was going for a walk. It must have been my lucky day!  ;)

Ha! I just fixed that one crummy channel 7 on the second board I made. That's the second bad trim pot I've had to find and replace! I guess I should test them before I put all this stuff together!

This is the progress on #4 so far...

I'm really running out of parts!

Dig the IC sockets man!

I had to pull pins out of other sockets and arrange them into 8 pin dips!

All of the parts are in place. Now I have to wire it!  ::)

At this point I can make this layout without even looking at the drawings!

I just ordered 2 more of those 8 channel USB sound cards.

HERE:
http://usbgear.com/computer_cable_details.cfm?sku=USBG-SOUND-71&cats=121&catid=121,637,136

I also figured out how I'm going to make a nice box for the sound card and the correction amp.  ;D

It's just too freaking cold to work in the garage!  :P :-[

Putting it in a box!

This is Lexan (polycarbonate). I cut it on my table saw today!  ;D

Tough stuff!  :o

I still have a lot of work to do, but I'm pretty sure this is the material I'm going to use.

Well, I tried Super Glue and it didn't work. Then I looked it up on the Internet and I found that I need a very special kind of glue for polycarbonate!

Pat Catan's doesn't have it, so I guess I'll have to mail order some.

I have the box figured out and it's going to be really cool!
