I reserve the right to do anything I want to do on The LaserBoy Forum!  ;D

If I want to turn it into my own little head trip, that's my problem!

I like to read parts of it more than once every now and then.

Besides that..... This forum is really for the aliens who come to Earth ten thousand years after the end of human civilization. I want to make sure I left a good impression.

Ok,


So I ordered the spacelas 20k's.

So today after I got home (working 2000-0800 right now)

I decided to dig into setting up my studio/office/pcroom/lab.. LOL


I believe I ran across a 7.1 pci sound card still in the box/w cellophane.  I will revisit that box when I get home in the morning. 

James.... I have done some searching on modifying a soundcard.  I like to read read read.. then attempt it.

oooh.. while box hunting today.  I found a Greenie Pointer.  I have it here at work with me.

I was wondering if anyone was up to tossing me a link for building a TTL/analog driver for the greenie.  I was thinkin of heading over to the machine shop and seeing if I could make my own heatsink for it tonight :)

ramble ramble...

Hopefully this weekend I can get Laserboy loaded and tested athome.   Oh if I plan on running it on a laptop should I go looking for a USB ext sound card?

.... ooohhhh shiny....... :P

This one right here is OK.

http://usbgear.com/computer_cable_details.cfm?sku=USBG-SOUND-71&cats=121&catid=121%2C637%2C136

It works!

It's not the most perfect thing in the world. It has a couple of issues. For one thing there is no voltage regulator on the board, so the audio gets some noise from the power supply.

But it is cute and convenient for the job of lasering with a laptop!

I use one!

In my rig I used a FlexMod to convert a green pointer to lab style analog

That blue box is really only 6 channels of analog audio out.

There may be 8 channels of digital audio on the optical, but that does you no good.

Other than that, it works well. It is a bit better than the 8 channel version.

Both of these devices have C-Media USB chips in them.

I have working laser DACs made from both of these USB boards.

As soon as I say that I'd need something more. haha.  I sold my 100Mhz teks when I moved here and now just have the one I got from you.  I finally ordered some test leads for it last night.  I'll need it for TTL testing very soon.
