My blu-ray won't light a match!? PHR at 120mA!

That's exactly what I thought but I think a driver doesn't work like a transformer, I think there's a voltage regulator inside that works like a variable resisotr that adjust itself to keep it constant. I'm totally saying this while ignoring how does this really works, but I think we can't apply this to the drivers since there is not any kind of transformer inside :P

Right, it's more of a variable resistor limiting the output to the current you set on the pot, which IS a variable resistor. The way I understand it is it keeps your current stable to the diode. I'm not an electrical whiz but I'm pretty sure it's not the same as a transformer.:yh:
 





At what distances are you trying to light the match and cut the tape? As for me when i finish a build in focus the dot to about a foot and then work my way up an additional six inches for each new test.
 
I know with my build the sweet spot is about 8 inches. Here is a video I made and I had measured the distance to find the sweet spot but I still had to move the host to burn the flash paper. I moved it less the a few mm but it made a huge difference.

 
I've just been told that it's not a !rksctr, it's a lm317. I've made a new thread to discuss this because I now know the problem is that this driver needs 9V, something the CR2 cannot provide.

Yours,

well at least let us know if you get it fixed, you CAN EASILY measure current on the LM317. and turning the pot is MUCH safer as it is a 25 turn pot "most likely" not a 1 turn pot.
 
its a linear lm317, no pot. And the problem is not aboutthe driver malconfiguration, the problem is that it needs 9V instead the 7.2-8V The cr2 can give :S
 
There have been many other threads about this same problem. You said your lens is ok, but aren't you using aixis acylic right now? If so, be sure to cut off the back side of the lens. Just make the light entry opening larger. Since blu- rays have a shorter focal distance, the normal entry hole will be too small, blocking some of the light. Just allow more light through, and you'll be burning blu in no time!

But make sure you get that voltage fixed first! :)
 
ya know that could very well be it meatball, open the back of your lens up so it look JUST as wide as the front. it allows ALLOT more light in, and is said to improve blu diodes slightly due to their focal distance.

then again, i have a PHR that burns just fine with the closed back lens. "stock acrylic"
 
Isn't it ok this way alredy?

where is this suposed to be? the piece of plastic lens or what? I can't see any part like the one in this picture rog :S
 
It is ths bit between the spring and the chrome focus bezel in your photo, the lens nut, the plastic bit that holds the lens with the thread on the outside.

Mine is alredy opened then, but as in the photo i uploaded, it's just a small black plastic, not a metalic piece...
