Thanks again guys! :D Jerry the host is awesome man. It feels like one of the larger, more sophisticated hosts by the way it's been deisgned - except miniaturized!! :beer:

Nice build and tutorial. Thanks for sharing.:beer:

Keep us updated on the life of the unit. I had a 1W unit that I built but it only lasted a few weeks with minimal use.:cryyy:

Also I did not see it say what current the driver is set to?

Thanks and you're welcome!! I've followed & learned from only the best, I should be thanking you. I know what you mean also about its lifespan at 1W, it fears me to think that it could go anytime :(:angel:

To my surprise though, it doesn't get too warm after a minute or so of runtime. I know that doesn't have everything to do with how long it will last but I thought for sure the host would get hotter than it barely does with such a small heatsink. Nonetheless, because this seems to be an uncommon 12X - I'll keep an update on it! :beer:

EDIT: the driver is around 650-680mA, it fluctuated a little when I was testing it

Welcome to the 1W 405nm Club.:wave:

You got yourself a Great diode there. 650mA and putting out over 1W is Very good.:)

I love it!
Now I want 1.
Nice work, maybe your new house helps.

Thanks Angelos!! Feels good to be in the club, hopefully now they wont charge me for parking anymore!:crackup:

Thanks, and so far it hasn't helped! I've been unpacking, redoing plumbing, adding shelves, installing electricity, rebuilding my studio, ect for 2 months until about a week ago. If it weren't for this place I'd have 10 new lasers by now!

HA I'm kidding man, the new place is great :beer:

A nice thick layer of compound is used for maximum bonding & heat transfer

Shouldn't the thermal adhesive used be as thin as possible just to cover up all the microscopic gaps in the metals? This is from my experience with desktop CPUs, where a thick layer of thermal paste will have poorer thermal performance then a properly done thin layer.

Very nice build, tutorial, and power, 1W :beer:

You got a very efficient diode here, I hope yours run for many hours :yh:

+1 for you

strange, cannot find my old post...

I was saying that I found it very hard to solder on the aluminum cases too, it seems it
just don't like to stick on to the metal.

Generally yes, however in this case I needed to use a thick layer so the resistors that stick up off both sides of the PCB on the driver do not touch the aluminum pill. The thermal compound provides maximum heat transfer with no conductivity, if I could stick the aluminum heatsink directly on the drivers' main resistors that quickly heat up without shorting the circuit out believe me I would :beer:

Thanks piferal! I hope it lasts too! :D

Solder does not stick to aluminum at all, I do not have the battery contact soldered to the pill. It may look that way in the picture but that is not the case, I have solder on the edge of the battery contact that creates a conductive wedge between the board and the pill :beer:

Thanks Cheech. 1W of 405 is something else man, especially in this compact host. This little bad boy throws a lot of power, some of my other lasers are actually afraid of it hehe! :beer:

405nm is my fave colour , and 1w of it will shred a balloon meters away! , get the sucker pointed at some GITD stuff :D

Indeed, a balloon massacre is definitely in order :eg:

good work sir!

yu should know the first words to come out of my mouth upon seeing the readings were " holy***" " followed by "Wow...". I remember having quite a bit of trouble with the 405s and to me what you've done is a real milestone, at least to me it is! I agree on the scary price though.

How well does it burn? What kinds of stuff do you think it can ignite? I'd love to see a "burning stuff" youtube video. Progress like this is really inspiring to beginners like me.

Wow! You using a 405G-1? (1 element glass?) 1W is pretty darned powerful.
We need to throw a 1W 405nm party or something?!?
