Hi all,
I was working on a 445 nm laser build, and in the middle of it, a tornado hit my place. Damage to the house was pretty minimal (we got very lucky!) but several trees fell on the house, and shook the house earthquake style. Dust everywhere, plus changes in pressure and shaking make me worried something's broken.
I have a pair of A140 diodes and a pair of Microboost drivers. I am testing with one of the drivers set to about 350-400 mA. My test load shows the Microboost putting out the proper current (the test load is 6x 1N4001 diodes and a 1 Ohm, 10 Watt resistor. Yes I know 10 watts is ridiculous. :scowl: It's what I have.) The diode is LEDing on me. I tried swapping with the other diode, but got the same thing.
I'm trying to think of all the things that could cause the diodes to be LEDing on me, but I haven't been able to find a coherent list of possible causes in the forums. Maybe I'm just bad at searching :thinking:
Any ideas?
Thanks!
