in loving memory of PHR, february 12, 2009 2:00p.m - february 12, 2009 2:01p.m. :'(
 





i had the driver set to 112mv. then i went and got a brand new duracell 9v. It went led on me while i was focusing it. i literrally died in 1 minute. And in case you are wondering, i even remembered to dis-charge the capacitor. :-/
 
Sounds like either ESD or overdriving.. I've killed many PHRs at currents above 100mA. I've found that for longevity, 80mA is ideal. I've had one running continuously for over 3 months at 80mA...

It could be that you killed it by an electrostatic discharge when you touched it to focus it. I've had that happen as well. It's relatively commonplace in the winter months since the air is so dry and the case of the module isn't grounded..
 
very interesting. when i get in some more i'll definately drive them down to around 80. thanks.

also under the red lasers section and the thread name "driver help" i posted a pic of how i am using my mm to test the load of the driver.

I have killed at least 6 for various reasons. Some were overdriven, some had broken connections and some for reasons unknown. One reason I suspect is just plain static. During testing I think I killed some by just touching the driver board - I now cover all the connections on the bottom of the board with tape. A couple died while in the pocket of my jacket - probably the cold winter day static thing once again. I think it's important to get them in the host ASAP to get some shielding.

If your circuit configuration will allow, connect the case center-pin to one side of the diode. I always connect cathode to case, and solder a .1uF or larger across the diode pins, and have never lost one to ESD. ;)

Re your red laser thread, the DVM setting you have shown there is correct for testing the Blu-ray. My comment just applies to the red.
