Hey guys,
I'm having real trouble figuring this out.
So I built the cicruit, and I used an NTE956 regulator, as the LM317 I had did the same thing, so I believed it was faulty. Its the same chip, just by a different company.
My problem is this:
When I measure my mV, which would give me my mA, across a 1ohm resistor in series with a 100ohm load I have in place of a laser diode, I get a stable output ~41.4mV (this is for a bluray) This doesn't change in any way.
I then put my bluray diode in place of the 100ohm load, you'd think everything would be fine right? WRONG.
I get ~41mV right when I plug it in, but then it slowly drops... and drops... and drops... until it reaches zero. What is the problem here?
Is something wrong with my diode?
I uploaded a video, and the dot is BARELY visible on my hand, it looks very brihgt in the video however. I took it with my phone, so forgive the quality.
