Hello everyone,
I'm new here so I hope this is the right place for this thread.
My plan is to make a collimated light projector for use as a HUD. All the graphics will be drawn by a raspberry pi with data from outside sensors.
I was considering using a simple small LED projector and collimating that, but they are pretty bad in terms of efficiency, and output a ton of heat for not that much light, and pretty bad blacks.
All I need is green lines anyway, so 2/3 of that projector goes to waste, and Vector drawing seems way cooler.
I've been looking at galvo sets like
this or
this on ebay. These seem like a right choice in terms of cost.
My question is, how can I output Vectors live from the Pi to those galvos. the boards that come with it have microphones, so I think this is for a musical show type thing, so It might by difficult.
Again, quite the novice at this whole laser thing, so any info/idea is greatly appreciated.
Thanks.
