Yes, if your software supports it. LFI has entries for 8 channels, but I don't know what the AR and AL stand for. You'd also need support for the extra channels on your correction amplifier.

I must admit, I didn't get the Amazon one for the 8 channels, but rather because DX takes so darn long.

Nice find, the layout seems pretty manageable. Everything is easily accessible, with a clean arrangement.

I just finished my version of the correction amp, is like that of dr. lava but is a bit more sturdy
if someone need it i can send gerber files or copper layer mask

Another video of home-made laser projector:
YouTube - Testing portable laser show with 12V inverter

I have it hooked up to a 12 volt vehicle inverter to test for when I do an outdoor show in Key West, Florida at the end of this month.

It can easily project to 200' x 200' image from 1000 feet away and even light a match from across the room: YouTube - 2 Watt RGB Laser Projector

Lookin' good Paul!

Make sure you post some pics of your show.. I wish I was in Key West right about now.

I've run projectors off inverters fine. Even the cheap square wave inverters will work, as the AC is just rectified as soon as it gets into the switchmode power supplies anyway.

Yup, that should be no problem at all. In fact, virtually all off them will run on 150-300 volts DC as well.

a Question, for that i could not google an answer:

How much Computer power the EzAudDAC needs to play shows smoothly with full XYRGB and 16bit? On my 1,86Ghz Centrino it pushes the CPU really hard, making the fan squirl on max. Any chance to run it from a Atom based Netbook?

 

[carmangary]

I'm not sure I understand.

 

[Bionic-Badger]

At least on my computer, most of the CPU usage is from the line drawing in the preview in LFI, not from the data being transmitted.

 

[carmangary]

I'm not sure I understand.

Windows 7 also removed the hardware acceleration for GDI graphics (which weren't great in Windows XP either). I guess he could run LFI with the screen preview off or use Spaghetti or something else.

 

[carmangary]

I'm not sure I understand.

Just ordered the Audiolase from 300evil as suggested by the first post. Hope to be able to see some ILDA action soon Now I gotta search in my couch cushions for some more more money to buy Spaghetti -.-

 

[chipdouglas]

pm carmangary. he was offering a crazy sale price on spaghetti. i got the full version for $20. i don't know if the sale is still going though.
