dvd rw diode help

[mybeat]

I've dissasembled my HP dvd 840 (can burn @ 16x) and took out the diode.Well actually 2 diodes.How can i tell which one is the right one?They look the same.
I hooked them to 2 AA batteries seperatly and noone had any visible beam.What could be wrong?
Maybe i need some sort of a lens?
I've ordered Aixiz housing for it but, i dunno will it work or not.

Start by reading the threads here.

And welcome to the best forum on the planet!

Start by slapping yourself hard in the face for connecting 2 AA batteries directly to an LD.
;D ;D

Thanx.
Now need to create a driver. :
Sad part is that i dont live in usa and it would really be a pain to get all the right parts for it.

I know this is offtopic but i dont want to create another thread.
What would be a best best buy Novalaser X 105 or Alpha105? Does alpha comes with the box?
Which one is brighter or are they simmilar?

 

[a_pyro_is]

I don't know about the boxes, but they are both guaranteed to average at least 105mW. The Alpha has a longer runtime as well as several nice safety features.
All this can be found in the Companies and Reviews boards.

i've found a capacitor 160v 47uF, could i use it?

 

[wooooooolazer]

yes that would work fine altho you dont need 160v thats a little overkill, just hope you didnt break the diode by connecting it straight to 2aa's, were they completely new or slightly used, because if they were completely new there is a bad chance that they could of killed the diode from the surge after sitting unused for a year and the large amount of ma it would give to it. Hopefully since you didnt use the aa's on it to long it should still work.

...lazer... ;D ;D ;D

it may be too bulky to fit in some casings, but you could use it anyway. If you are planning on using it in parallel with the LD, a 10 or 16V 10uF tantalum cap would be a better alternative
