I`m building an engraving tool for black plastic.
I intend on using the CD burning laser out of a dead DVD burner.
I made one about a year ago without any driver and it burnt out fairly quickly, of course.
I have a much better design with a large aluminum heatsink/stylus.
My question is:
What rating of driver do I need to protect the laser and regulate output?
Also: How much voltage is needed?
The one I built before ran directly off of 2 AAAs in an old laser pen.
I work in a Mold-making shop and I want to mark our test parts where the mold needs work done.
Space is not an issue because the power supply and trigger will be separate (project box) and have a coiled telephone cord to connect to the laser.
Also the laser itself is in an axiz module and press fit into the aluminum.
I also understand that this is a very dangerous tool.
It will only be used by me in a very industrial environment.
Any help will be appreciated.
