What's the rating ohm rating on the resistors? I would also like to know the type of transistor (NPN or PNP) and the amperage input/output I can see 9 volts input unless the battery happens to be dead. Btw what's the headphone style jack for? (in short I'm wanting the technical details for how to build my own laser using the same kind of diode)

I think he said it was an LM317.

That looks like a lot of heatsinking. Is it a a130 or a140 Tesla? If a140, I would think it should be able to last with that much heatsinking and based off other's. Mine is a portable running at 1.25A and it hasn't died yet (though I do do short duty cycles). What current is it at right now?

sorry haven't been on this thread in a while the resistors are 5 ohm and its set to 1 amp but i've run mine for hours

Yup. Now I need to add 2W, 3W, 4W and 5W signs. Oh how those 445nm keep getting more powerful.
Here we go. Download and print out on HQ sticker paper or vinyl if you've got a wide format printer.
These are infinitively scalable. VECTOR based.
Normally these kinds of graphics are pay...ie) $35 a shot! .
Hope you guys can use the signage.

Yes indeed, it works well for flashlights and pointers. However mine are vector based and can scale to any size to infinity.
