PF-114 RGV 300mW ILDA - anyone own one?

Yeah I know what you mean, the screws are really soft eh. Try another screw driver. post some pics when u get time. I still want to know what the scan speed is for the scanners. The builtin demos look like they run slow. Usually the animations are more flashy than the simple animated lines. I notice with ishow overclocking the scanspeed to about 40k the flashyness goes away and is ok on the simple vector demos but makes more complex ilda frames look mutant!

At this point all I have is the projector. Still groping in the dark. Don't know where to go next (DMX ???, DAC ???). I really need a VERY SIMPLE how to guide Like the "Dummies Guide To . . . ". I'm so lost DMX and DAC are just vague terms to me. Do I need both? Any sugestions?

a DAC is a Digital to Analog converter used to control ILDA enabled Lasers( 25pin connection port on the back of ur laser). Dacs are small boxes that just interface between the laser and your computers USB port *(or PCI slot via interface card.) usually bundled with basic laser control software to draw animations.(more info look here: http://en.wikipedia.org/wiki/Laser_p...ller_.28DAC.29 )

DMX controller looks like a sound mixer but its for controlling lighting that is DMX enabled using a DMX cable (PF-114 has this connection too, its the round one). Some DACs are hybrid and can do the ILDA animation stuff and also DMX control. (more info look here: http://en.wikipedia.org/wiki/Laser_projectors#DMX )

Soundcard DAC is a DIY DAC that uses a modified USB soundcard to interface with the 25pin ILDA port on your laser. Only a couple of laser software programs work with it that I know of, Spaghetti and Laserboy, might be more out there. If you want to make a SoundDac urself look at this tutorial, its very good: http://www.photonlexicon.com/forums/...d-DAC-Tutorial

If you want one made PM me and I will let you know more. I'm getting one made at the moment.

hairspray, man i wouldnt want that all over optics.....

Yes, good that the Airholes have a Filter...

Xer0,
thank you for pictures and video,

Can you make some photos inside? (will be good to see quality of adjust devices... lasers and galvanometers mounts... their temperature safety...)

there's a pic on the first page of this thread. It looks like the optics mounts are adjustable, so that's pretty sweet..

Yes you can adjust optics, very easy to calibrate, my laser was way off when I received it, tool 30 sec's to get the red centered on the Violet.

I would be interested to know if anyone managed to hook one of these units up to a better DAC? I have a PF213C (Supposed to be 30K) and with iShow it looks dreadful. Would like to find out if it is the galvos or the iShow DAC that is the major problem.

Cheers

Hi djtuffer, I will let you know on this thread once I have tested with a soundcard DAC, i'm getting it made at the moment. I have a funny feeling that these aren't 30kpps as advertised because the built in demos look crappy nothing near 30k. I show DAC makes no difference unless the scan rate is near 40Kpps+ but of course the image looks distorted at that speed (same on spaghetti and ishow software using ishow dac)

Gary from spaghetti software has tested ishow DAC and says looks great on his 30kpps RGB projector but needs scanrate to run a little faster than 30k due to ishow DAC firmware and lack of documentation.

For anyone following this thread here is an example of a 30Kpps laser scanner. I'm not sure what DAC is being used to control the projector here but the PF-114 looks no where close to this speed (tested builtin examples/ishow DAC ishow/spaghetti ) ..

[Xer0]

Yes, you can see the difference like day and night. especially on the very complex bird and rose animation

PS: nice Track! i know its on my Phone somewhere... // it's on the Hardbass Chapter 13
