Hello, I have had a set of 20k galvos (with show card), a red laser pointer diode, and a green laser module laying around for some time and finally got a chance to put everything together but I have run into a snag.
To power the lasers I used a LM317 set at 3.05V and a TIP120 on the gnd side to allow the show card to control the lasers. This works beautifully for the red laser but not for the green. If I ground out the green long enough for it to come on to full power it will work for a while then fade out. Is there another way I can control this laser module or should it just go back into the parts bin? Here is the information I have on it:
Green Laser Module
532nm
<5mw
3.0V DC
<280ma
I believe this is the module (I bought it long before I found this site) : �DGM512-D001 5mW APC Green Laser Module Dot Laser Module - Laser Modules
-Thanks
