Doh! Well, I just got word that the Laser Boy Correction Amp is no longer available. Guess I need to look for something else, or build it myself.

Did you check with 300Evil? He has his own version of the board.

[djpsych]

Perhaps he just ran out, or he doesn't have all of the components to complete the kit?

He does not have anymore complete kits just the Bare PCB.

Where did you end up ordering your parts from and can you tell me the cost?

Here is a list of all the parts I ordered for the Laserboy Correction Amp. These parts can be found at other places also, but these are where I ordered the parts. The quantity listed is what you need for the amp, but sometimes there are minimum quantity needed so you will have to buy more.

Parts List:

Also if you need hookup wire I recommend getting the 22AWG solid 100ft from Jameco with your order [Part# Black: 36792, Red: 36856, Yellow: 36920, Blue: 36768, Green: 36822, White: 36881]. For building you will need wire stripers, solder, and a soldering iron. You may also need to purchase four standoffs.

Im curious, I just see six channels in the pics. (5.1) Six caps to wire from. not eight.

Yup, looks like two channels are unused. I tried to trace the two pins (which appear to be the side speakers) from the chip but had no luck - either they are not soldered down or the trace runs under the chip - either way, the 7th and 8th channels are there on the chip, so someone with some mad soldering skillz should be able to attach some leads.

I'm only building a single color projector with intensity, so I won't need all of the channels for my application, the 6 channels it provides is more than enough.

Thanks,
Oryx

Hi Oryx

So you just need 3 channels, for now
Later you can put 2 more colors
So 5 channels.

Cheers,

Hi Oryx, sorry about being sold out of the PCBs. 300Evil here can probably hook you up, or, you could go all the way and print your own PCB using toner transfer method. It's a single sided copper layout so printing is pretty easy.
The sound card you have linked looks to be a good solution, better than the newer L-shaped PCBs on DX that don't have the 3.3V preregulator, which is important to minimize hum and noise in the signal.

I've attached leads to these chips as you describe to get the other 2 channels, but it's only useful if you want to play back 8 channel wavs. All show software that uses the DAC as a DAC uses a separate audio card for audio output.
Have fun and welcome!

Oh wow, thanks for listing all of the components out and providing the links! I added the correct quantities and the total isn't all that bad. *I'll order the PCB and if it ships, I'll order the components and just build it myself.

*EDIT: Spoke too soon, drlava posted that the PCB is sold out.

Thanks again, great info there. I hope I can get to those steps sometime soon

Oh no! Well, I guess that answers my question. Do you have the templates for the PCB or know where I can get them from? I definitely wouldn't mind making the PCB myself.

Thanks,
Oryx

[300EVIL]

Yep, I do have audiolase kits available. http://www.photonlexicon.com/forums/...ight=audiolase

[Oryx]

Yep, I do have audiolase kits available.

Just a bit on the pricey side, no offense

I'll craft my own board, will give me something to do this weekend beside hitting the slopes. Thanks though!

I uploaded a PDF of the board copper to the PL ftp site. Let me know if you need tips on printing. I have found the waxy backing of printable mailing labels makes a great transfer medium after it has been scratched up with a card.
