USB Audio DAC mod + LaserBoy Correction Amp

[James Lehman]

What's the word on the new LaserBoy ILDA output? Have you tried it yet?

James.

I have not tried it. It might be awhile since I am kind of busy getting ready to go on vacation. Thanks for adding support for those formats.

[James Lehman]

Well, at this point I have nothing to go on but the document you sent me and the fact that I can save and open the files in LaserBoy. That doesn't prove anything, really.

The application I sent you a link to is able to read and write those file types so you should be able to use it for all the testing you need.

Hey guys, I have got a bit of trouble here, It seems to be a blanking issue but im unsure, Any Idea's ?

can you snap a shot of frame 31 of the default file.

you may need to adjust your offset.

That definately looks like a scanner to color mod timing issue.

Your scanners are electromagnetic devices that actually turn an electrical
signal into physical motion. This can not possibly happen instantly.
Therefore there is a delay between the electrical signal driving the
scanners and the real position of the mirrors.

The blanking on your laser, however is instant! It is purely electronic.

So, if you feed a set of signals into both the scanners and the blanking,
the blanking will be ahead of the scanning; or rather the scanning will be
behind the blanking.

LaserBoy has a feature to correct this.

From the main menu, go to menu 'b'. Choose option '4'. The first thing it
asks if for an offset for both X & Y. Input 7. Now you can [Esc] out of wave sample offsets. You have just said that you want the signals for X & Y to arrive 7 samples before the signals for the colors (almost)!

Now you have to apply this desired offset scheme to the wave. Choose option '5' from the wave utilities menu and enter the name of the wave file you want to shift.

Ta Dah!

The sample offsets are stored in the header of the wave file so you can
apply a different offset scheme and LaserBoy will know how to un-do and
re-do it correctly.

Thanks for posting the picture. That always makes my day!

Cheers james. That worked great, But is there a way i can fix this without having to change settings, so that it will work with other apps, like zoof's games and Spaghetti ? coz the offset is well off with Laseroids and tennis ?

[thesk8nmidget]

yep just need to change your offset.

i will walk you through it when i get home.... i am at work and will be there in about an hour


EDIT:

just saw james beat me to it!
