Hello,

I’m been busy the past couple days,

I manage to make the correction board
After blowing one tl082 *love that smell* and a lot of adjusting its working properly.

Al I need to do now is make a nice casing to protect it.

I test the correction amp with He-laserscan and the EzAudDac
That workt better than expected.
Tomorrow I give laserboy a go!

I hope to make some pics and post them here!

Hello,

I’m sorry i don’t told the hole story,

I like to control my 400mw green ttl laser
With 20kpps galvo’s and ilda port

First I was struggling with an lpt dac
That diddend work for me.

Then I found laserboy and the soundcard dac.

So I bought a pci 5.1 sound card
With a c-media CMI 8738 chip

And already solder wire’s before the caps

I have a  +/-12v from the psu
So don’t need the dc/dc converter,

I have some solder experience
So I want to give it a go.

Is this the right drawing?

Hello everyone,

I introduce myself considering I’m new here
my name is Frank Hoogeveen
I’m 20 years young
and from Holland

now I’ll like to order a Correction Amp but don't have a credit card.
To order It from http://hacylon.case.edu/ebay/laser_diode/LaserBoy_Correction_Amp.php
*Google checkout needs a credit card*
are there other possibilities to order?
