So I've though about building a laser projector for some time now, but I never got around to it. Plus it was slightly daunting to me with the various choices of DAC, Software and hardware.
Well, for my college course I need to build a project, so I decided to get a two for one and get a laser projector and fulfill my project requirements.
So this project is still mostly in the theoretical phase. so of course any suggestions will be helpful. Since I'll be DIY making everything except the scanners my plans are bound for a few revisions along the way to the finished project. So my current plans will not necessarily stay consistent.
Hardware:
I'll have all the optics on the projector mounted on a 7"x15"x1/2" aluminum plate. I'm going to try to put it in an aluminum carrying case. Mirror mounts and dicro mounts use 2" by 1.5" Al angle. This puts the beam height at about an inch.
Diodes are Mits 500, PLT5 450B, and PL 520.
Aluminum plate before cutting.
Optics:
I'll be using the FS mirrors, dicros and lenses from DTR. The 638nm mit's will be corrected using salvaged single axis positive lenses and DTR's lenses.
Electronics:
My current plan is to use (THIS) design for my diode drivers. The 5V is for the input, 9V is power and 8V is simply a consistent voltage for reference. Circuit design is not something I am very good at so I'm figuring it out as I go.
For the DAC I plan to use an arduino possibly with a few external components.
Software: Whatever free software I can find to play with.
So, HE laserscan and LFI.
The projector will be powered by a 16V 4A laptop charger for wall power or 8*18650 Li-ions in series. For the scanners I plan to get some cheap Chinese ones from ebay. While not the best quality. they will work fine for what I want it for. So far my build costs looks like it will be between $300 and $400, so I'm hoping to keep it under $400.
