Hi, I´m new to this forum and I need some help making a driver circuit.
I´m trying to make a Blu-Ray laser pointer with this diode 150mW 405nm Blu-ray Blue Violet High Power Laser Diode - eBay (item 280459764179 end time Apr-02-10 18:10:21 PDT) (but I might go with this one PHR-803T HD-DVD laser lens with violet laser diode blu-ray [PHR-803T] - $10.49 : Modwerx Shop )
The problem I´m having is that I used the driver circuit on the picture (from kipkay) with the 150mW diode and it worked at first, bud then it ruined the dioed.
So what I´m asking, can any one help me make a driver circuit for ether one of the diodes so I can run them at their maximum power? (the smaller the circuit is the beater)
