UMD? :-?

(Googling for some context...)

Oh, a handheld Sony PSP format? A Kind of disk?

Since it looks like it's just a disk reader, and not a burner, it probably uses a low-powered diode. Only DVD burners have the high powered diode because they need the high power to melt or change the structure of the disk to write the information on it. And they have to be really high power because the disk is spinning so fast, the laser does not have much time to melt the little dots of information into the track as the surface of the disk goes whizzing by.

I don't even know if a UMD reader diode is in visible red or not, it might be IR.

It might burn if it's anything significantly over 5mW and you focus it real tightly with a lens, but it would only do so at very close range, make very small burns, and wouldn't be what most people here consider "a burner".

Yeah, a UMD drive is just a miniature DVD drive, and since it's just a reader, it's most likely ~1mW.

Also, take that $20 and buy one of the group buy diodes! ;D

It has to be a BURNER or WRITER drive.

To simply READ a CD/DVD type of optical disk takes only a very low powered diode.

To WRITE or BURN, it takes a much higher powered diode to actually melt the the disk inside just a bit to change the arrangement of the microscopic pits and dashes that make up the data.

Heh, before you buy the DX 50 eager beaver, pot modding the DX lasers do nothing. They have a circuit, the last one before the voltage hits the pump diode, that limits the output current.

I got one DX 5 which I pot modded to a whopping 15 mW.... Not worth the effort. If you plan on modding a greenie, you must have the meters to know what you are doing and the driver has to have a pot - some don't.

i was going to try potmodding a untrue one and even if it does potmod it a little bit hemlock mikes went up 3x its original power so that would make mine a 150mw

I am afraid it does not work like that. Mike indeed trebled the out put of his, but look at it another way, he gained 10mW, you would be lucky to do the same on a 50mW, you may gain 10mW if you are lucky, making it a 60mW, but you will never treble its output to 150mW.

Yes pot modding a higher power green is kinda pointless. Most of them are already at their max in the first place so messing with the pot will give you little gain at all. Maybe a few mw at best. The reason Mike's went up so much is because it was a 5mw to begin with. A lot of companies turn them down a tad to get a more stable 5mw laser.

The best way to get more out of your higher power greens is to use some lithiums and that will only get you a few mw if that.

Reaper --

It is the luck of the draw on pointers and SOME DON'T HAVE POTS TO MOD.
You will need a very good understanding of SMT technology and all the equipment to get maybe 10 more lousy mW. *My other DX 5 was already maxed out at 10 mW.
Come back down to earth. *The old style DX lasers often put out a little more with e2 cells but they all have a limit to the output based on LD, MCA and $$$.

Mike

By the way -- you will need a power meter to "see" the difference between 5 and 15 mW. It's not worth the effort unless you are into electronics.
