Hi,
Just wanted to say hello, and say why I am here.
Really quite new to Lasers, can tell you how laser light is produced at the atomic leave as electrons jump between energy states, but I have to say my knowledge really is from the science side and not at all engineering.
My wife got me one of these a while back Laser Star Projector and its a great (if simple) laser display which has now been taken by my two year old as her night light
. I recently purchased a Raspberry Pi computer board which I have been using to generate random star field grids. Basically I am computing a list of X,Y points and there brightness.
So the next part of the project is to translate this in to a laser display. All i know is that this will require some Galvo's and a DAC/amp to drive them.
I am not sure if I should purchase a DAC, or attempt to build on my self, and the same with the scanner. I no i need to read up a lot on this, but I am hoping to get some pointers from this forum as well.
IF I can get a scanner working and projecting my current images, I will be moving on to be creating real star maps rendered in real time by the Raspberry Pi, along with other generated star fields. I know many people have done this kind of thing before, but I just want a little project to play with.
Looking forward to meeting you all.
Aaron
