    Default Lists of current laser DACs & Control Software

    Hi all, I came across a pair of posts ages ago that tabulated the then current list of Laser DACs & Control Software. I bookmarked them, but it now seems that they are not on the server any more. I tried to search for them, but to no avail.
    Does anyone still have copies of these resources? It might be a good idea to maintain them as a 'sticky' or similar? Sorry if I've posted to the wrong forum, or if I've missed something obvious.

    I have a parallel port DAC & a copy of Popelscan. My 2W RGB laser should be delivered soon, which has a standard ILDA interface, but I don't have a DAC/Control solution to control it! Are there any freeware or low cost solutions? I've heard of iShow & Helios DAC. Also one which is based on an Arduino, but it would be great if there was a central resource to list them.

    The last controller I used was the Laser Systems (Wales UK) Magnum hardware controller back in 1987. This setup was on the roof of a nightclub in Spain, & used standard General Scanning Galvos & a nice 20W Coherent Argon laser. So it's been a while!

    Many thanks, Simon B.

    The current state of that art for free is using a modified sound card (to remove the dc blocking caps and amplify/scale to match ilda levels--just takes a few opamps) with laserboy http://laserboy.org/ (also has details on the sound card modifications) openlase https://marcan.st/projects/openlase/ or LFI player https://sourceforge.net/projects/lfiplayer3d/ Of those three I find LFI player to be the most straightforward to use, with the ability to directly generate abstracts or play back ilda shows (note - to get the demo files for abstract generation you need to go to the downloads page for the older 1.1.5 version).

    More recently lasershowgen http://pages.bitlasers.com/lasershowgen/ added the ability to work with laser dacs and while it is not free ($30 for full version) it is open source and even the free version is more capable than the aforementioned 3 free ones.

    There is a really nice kit available of the LaserBoy Correction Amp to build a modified sound device.

    I also provide very good tech support for you to build it.

    That page was probably the Wiki. It yet needs to be resurrected.
