Hello guys, from Southeast Asia, Malaysia
This is my first post... sadly not in the welcome section but the repair section. I thought I would post after I finish my first build from a DVD burner. Gotta have something to show the club right?
Anyway, I made the Lm317 circuit without the capacitor, a 4.7ohm resistor and a pot with min resistance of 0.2 ohms hooked up a 9v battery with a 16x red in Aixiz housing. (tested beforehand)
My second time trying to get the circuit to work (fried the first one due to impatience and lack of overall knowledge).
Potentiometer at max resistance, slowly wind down.... it started as a led sort of red light, then at a certain point, it started lasing (I assume it means the observation of bright red jumpy particles thingy). It worked, not very very bright, and the pot isn't at its end. (I had duty cycles)
So I tried to tune it further down, those few degrees made a LOT of difference in terms of brightness.
Near the end of the wheel, it suddenly became dim (no more bright particles)
My mind was like o.snap.
I turned resistance back up and then proceeded to slowly decrease it as I did before.
It started lasing again, Yay. (I don't know if it still has the same threshold current)
And then, after awhile, it went led even when I turned resistance all the way down.
Here's the confusing part, it occasionally (rarely) lases for brief moments when it is passed the threshold.
Do you call that a led diode?
A DVD diode is probably like the utmost cheapest laser here, but as a Asian student from a middle class family, there is little left of money that you won't feel guilty for spending.
Perhaps it's true that right now, all the reason I wish to own a powerful enough laser revolves around pointing them, looking at the beam, burn stuff; which is in essence, not constructive & not useful.
But those are the things which has brought me here, and hopefully make me stay in some way.
Right now I feel so stupid, angry, sad and confused
there's people out there who just hook up batteries and they get similar results as one would with a driver. Yet I play by the rules and all kind of unforseen circumstances come to play. Annnd, my diode probably died. At the same time, I still haven't any clue (pretty sure I'm not gonna get anything by searching: "my diode fluctuates betwen led and laser")
Was looking around at degree courses also, apparently there's :
PHOTONICS ENGINEER just, wow.
