anybody think any of these drivers would be appropriate in driving SenKat's GB Diode?

specifically im looking at the "EU-37 laser diode driver board" or the
"EU-38 laser diode driver board"

gazoo; wouldnt the EU-37 laser diode driver board be more realistic since the GB diode from SenKat in CW mode only draws 130mA?

in other words;

if i was to 'overclock' my diode, rated at 130, 200 would be as much as i'd want to risk it no?

I've pushed one of the GB diodes to 500 mA !!!!  That's with TEC cooling.

I would recommend staying at 250 to 275 mA ( WITH HEATSINKING) untill you have a feel for the circuit and diode.  Once you are happy with the laser, push the other one to the MAX !!!  Be Careful..

I must have a computer problem here, many posts here don't show capital letters or punctuation.  I gotta check this out - It makes reading difficult for me.

The point is even if you want to run your diode at 130ma, what are you going to do 6 months from now if we find 300ma diodes. If someone did a GB for the EU-38, I would but a few.

And Mike is right, don't push your diode too hard to begin with. You will be surprised what 200ma of current can do. ;)

Gazoo --  

You got it -- Start in a LD "safe" area, enjoy and then start pushing the limits.  There's a bunch of us who went for the MAX right away and went to bed unhappy.
Ooohhh -- you won't believe what 350 mW can do !!! Slash tape !!!

Well I have already went to bed unhappy a couple of times. I don't think it is because I pushed the diode too hard, but rather ran it too long. I need to be more careful.

I have my TEC cooler and LD independently powered by two of daedal's circuits, but running off the same power supply.

My RS rheostats came today so I have very good control over the TEC and LD.

THose EU-38's look good to me!!!

Does anyone know the cost per unit, or what the shipping works out to be....

I can see myself getting 1/2 dozen or so right off the bat!!!

Maybe we can coerse Daedal to do another sample deal for testing.....that way we can know what we're getting before we order!

If I had the proper equipment to be able to test .......

Oh well....

But seriously..those look like WINNERS to me!!!

Just imagine the flashlight mods we could do!!!!

WOOHOOOOOO

And here is the other side with the rheostats. I love 3M double sided sticky tape.. ;D
