Hi! I'm building my second red laser project, is a more compact version of my actual red laser. It uses a 24X DVD burner laser diode (from a LG GSA-H55N [my favorite burner for getting LD's]) that runs at 415mA, I don't know how much mW they put out, I think is around 250mA, if someone know let me know! :beer:
Instead of building it from a ready MDF box like my other laser, I build it using a custom format of 11cm X 3cm X 7cm. Since every shape of MDF have 0,3mm of thickness, it gave me a internal space of 10,5cm X 2.4cm X 6.4cm, was a bit complicated to get all in place.
Most of the pieces used here was brought from a technological recycle center, avoiding to be wasted.
Here the shapes of MDF:
The box pre-mounted:
Size comparison with my other laser:
First simulation of the pieces in place:
Done the fan opening:
Driver assembly (the resistors of the DDL driver are on the other side of the board):
Glued some lateral MDF shapes:
Generic aspect of the laser:
Test of the driver:
Lens (salvaged from a old Creative 24X CD reader) in a LD housing:
Lens glued in place, but not well focused:
The unfocused "DOT" (rings are common using that lenses :yabbem: ):
Focused beam (not a good photo, but is OK):
Beam melting insulation tape (only to confirm that is powerful):
Assembling the things:
Done the assembly and working:
Now the next thing I need do is pass a varnish into the MDF to make the laser most beautiful like my other laser.
Tomorrow I'll done the varnish and my new laser will be ready to rock! :drool:
To be continued ...
