Hi all...so I'm guessing that voltage not current control may have resulted in runaway current burn out but I'm not sure...I have a 10mw green laser module...standard module driver + diode in housing... I made a little circuit with a 555 and Tip32...thought pulsing would allow a little 'overclocking' without burnout. The system worked perfectly and for a week or so I was using it intermittently on my benchtop. Then all of a sudden one day, with no warning, no smell sound or smoke...it just stopped. I checked the circuit with an LED and also another (red) laser and it worked fine (although I then unhooked the red laser so I didn't lose another). I'm not sure what the problem was so if anyone has any suggestions please let me know..
Thanks in advance
