Re: Dual driver Skyray

you could sell just the driver manifold:thinking: I'll call it...

Re: Dual driver Skyray

Nice!

i just made a 445nm laser in the same host although i used a single driver.
really love this host and the gaint heatsink to was my first self-made heatsink:beer:

i like how you made your driver heatsink to:gj: mine keeps overheating... lol

That's a much better name... Driver tray doesn't sound half as good. Thanks, if you don't mind, I'll adopt that! Driver manifold is great. I have been asked about them already and it's a great idea to make them available as a stand alone or even as a mod to currently available sinks. This design would fit well for you interchangeable modules I think.

Nice!

No, 'long run', tests have been done as yet so mine may overheat too! I'm hoping not though. How long does it take for yours to drop out? What driver and current are you using?

I really like this host and think it has a lot of potential. Large internal space for the heatsink and lots of bare ally to bond it to. The fins make the surface area up to a host at least half as long again I reckon. I'm not totally keen on the rubber rings but this does seperate the hand from the host which also will improve dissipation to minor degree.

CAD drawings will be made in the coming week or so to go for manufacture. This may make them cheaper than if i had to hand build each one so I'll keep you posted on this.

Cant wait for the power readings, and hopefully the longevity of that soon to be very busy Diode haha

Well done. +1 for you.

Very Nice Morgan...

Can't wait to see this in action and power tested..

BTW... you can use a cheap glass ND filter in front of your
LaserBee I to up the Power Handling capabilities of your
meter.

Take a <1000mW 445nm Laser and test it on your LaserBee I..
Lets say it reads 700mW...

Put a Glass ND filter in front of your LaserBee I and measure the
same 445nm Laser again..
Lets say it that now reads 300mW...

Your ND Filter at 445nm has an attenuation factor of 700/300= 2.33.
which will allow your LaserBee I to measure up to 1050 X 2.33 = 2449mW
(Different cheap glass ND Filters from different manufactures will have
different results with different Laser wavelengths)
The only thing that will change is the reading resolution.. Instead
of having resolution of 1mW on the LCD screen... your resolution will
be 2.33mW per count with that ND filter 1mW=2.33mW

Just take your LaserBee I reading with the tested ND filter and multiply
your results by 2.33 (in the example above)..

Less talky, moar finishy!!! No really I cant wait to see it completed Morgan. You have made me take longer looks at my dual 18650 host!! Idea's idea's idea's.............

Brilliant! It just so happens...

I picked some up not so long ago and figured it would work but didn't know if the factors would be linear. Now I have to build a sub 1,000mW 445 for calibration? Where's the fun in that?!!!

I don't have a sub 1,000mW 445 at the moment which still leaves me beached, (only a 1,300mw measured on another meter increasing the possible errors and I'll never be happy with that!). I guess the response will be different with different wavelengths? Again, I don't have a suitably powered laser to do this either at the moment in fact.

I will just have to send it away or do some real rough measurements, (which I hate!). I think send it away, and keep saving for a LaserBee II!

Thanks for another cool tit-bit of laserometry Jerry! :bowdown:

N/P....

Even with the same ND filter tested at 445nm and giving you
a factor of "X"... using the same filter at other wavelengths
will not assure the same "X" factor..
Each wavelength you have would need to be tested and
recalculated...

BTW... why not just turn down the current of the 1300mW
Laser to do the ND test..

Or....

Take a 2nd ND filter and attach it to your 445nm 1300mW
Laser.. That should bring it below 1000mW and use it (with
the 1st ND filter attached at all times) to perform the above
ND test with a 2nd ND filter on your LaserBee I...

i use a single microboost drive inside the aixis module (i use the whole module ) with small termal pads on it, running it @ max it overheats in about 40 sec but i do get 1,16W for 40 sec

and yea i love this host to!
much room inside, sturdy feel, good finish, a decent clicky switch wich wont die on high currents, and place for a big heatsink
Im now looking for a way to use the assault crown bezel thingy on it as a focus adapter or attaching it to a focus adapter, im using a focus adapter from my pocket mini from Jay atm lol

p.s.
you can just peel those rubber rings off they are like ugly fat O-rings, i hate the looks of them

here are some pics of mine.

it aint a masterpiece but it was my first try on my mini lathe

i did have a small spring at the end of the module but i felt that there was to much tension so i removed it and made a solder blob for battery + connection.

@ Jerry - Two ND filters! Of course! I now have to wait for my 1,300mW to come back from testing too now then! I ain't winning on this one at the moment... :yabbem:

@ Xtrm2Rick - Yep that's a cute little number. When you say maximum for the driver you mean the standard 1A not the modified output of 1.2A? I think because it's not heatsinked and inside the Aixiz is the reason it will be overheating. That being said, who needs 1.16W for more than 40secs right?

[jander6442]

Whats up with people haten on the o-ring of late. I remember when people liked that look.:thinking:

 

[Morgan]

Do you mean the O-ring on the body? I'm not adverse to it on other hosts. I like it very much, for instance, on Mohrenberg's scratch built jobby. On this host though it's a big blocky square cross-section ring. It kind of looks a bit of an afterthought.

It would be a dull old world if we didn't have different opinions though jander! I'd just have perferred a little more girth to the body than the O-rings.

[jander6442]

I see the rings now... sorry, at first they looked like those pentagonal sections that some host have. I'm not one to bash others opinions it's just that in the last week or so I've seen members haten on o-rings. I say if you need them for funtional puposes( for keeping current from a contact) use them.

its running @+/- 1A no mods done on the drive just the solder bridges.
And yea 40sec @ 1W or higher is more then enough, i dont even use it to burn stuff i just like the bright fat beam in the night sky or in the morning dawn:shhh:
And ofcourse making the laser was a joy in itself to:beer:

btw i didnt know it was possible to connect 2 boost drive together to 1 diode

Ah, I see. I haven't seen any posts with hatin' in them. Yes, if they serve a purpose then use them.

I have other lasers I can be patient burning with. These start burning so far away from the actual focus point that they are almost too unweildy! Imagine that... A laser that's too powerful for us to be happy burning with!

Now you know! It was something that came up a while back but can't remember how.

That's awesome work there!

Very creative with the driver mounting and stuff... :gj:
