Hello M. Polak,
Also please allow me bump this thread one again and to offer you great thanks for this post. Unbelievably easy to implement this in software for my ESP32 based test box and ILDA/WAV player ILDAC-WAV (see: https://ildac.com) . I can't quite wrap my head around why the simple math...
After I got the main intended functionality working with the included software, I did not proceed with changing anything further.
To be honest, if you want to use it as a stationary laser, I think you will be better served by just buying a cheap show laser instead.
At this stage in the game, I have only found NOS. Kevin (Junktronix) is who I bought mine from. https://www.photonlexicon.com/forums/showthread.php/23344-Junktronix
Oh yeah, like those sold by Laser FX, Laser Show Systems. I'd forgotten our PLF info exchange in that thread. (I just found Laser FX's weblink on the R4-077).
Who else sells them?
In the past, I found that they performed about a 1/4 as well as the g-124s, even as big as they are!! (Of course, that's as-is not comparing to g-124s with the accelerator cards). They are tanks, though!
