Thanks! It’s not really my objective to make music

thanks both! I send and analog signal through Ilda, it's just voltages, ilda is not digital. check my website www.jestern.com

@@thejestern thanks! Hmm, I might just connect the galvo's to an audio amplifier so I can use a cheaper laser. Lasers with ILDA are always more expensive. Would a normal glow in the dark surface work with a blue laser instead of a UV laser?

@@erikpoephoofd yes that should work as well.

Hi the canvas is custom-made using some pigment and transparent paint. It took me few trials to perfect it. It’s difficult to quantify the time but I would say 10-20 seconds to disappear. So it allows me to draw quickly. Some material stays lit too long. It’s the UV part of laser light that excites it, eg red or green would leave no trace.

​@@thejesternhave you thought of diluting some of the UV paint for a second attempt to cut down the retention time? I'm not 100% versed in the science of phosphorescent materials, so I'm not sure if that would help it or just dim the output. Ah what am I saying you probably have

HI @@Enderdragon91it's still something I'm currently working on: understanding ow the material works. for now I have a satisfying mix. I noticed that with less material I get less brightness. The property of how long is the retention depends on the material itself, e.g. some compounds last longer and the effect is undesirable. So it's two variables: amount equates how bright, while chemical composition equates luminance time.
