The Imposible

Well it took me about 5 hours but I did it, yep I did what others said could not be done
I put double drivers in and egihnmas host and with two copper heatsinks for the drivers I might add
So this is a black powder coated 18650 direct press egihnmas host and it had a single driver in it and I was asked to put two drivers in there by the owner.
He said he had asked several other builders here to do this and all turned him down stating it wasn't doable. guess I showed them :beer:
so here is some of the pictures I took while doing the work.

This is what I got, some not so good wiring and bad solder joints, that didn't really matter as it all came out.


so I made a couple of custom fit solid copper heatsinks to mount the drivers on.

After setting the current I wired the two drivers up.


then a fit up to be sure all will fit inside and then some arctic silver to hold them in place and to draw off the heat.

And here is the result a nice output just what the owner ordered


Thanks for looking, feel free to post if you want.

Peace All...

That is a tight fit in there! Even in my custom 26650 host dual flex's was somewhat hard to get in there together

Very nice work Jeff!

Thanks Jay, it wasn't easy for sure, kinda like stuffing an elephant in a pickle barrel.

Ehgemus*

Nice build you got there Jeff Thats a tight fit!

BTW have you m-140's arrived yet?

Enjoy your week!

Sweet!! I alsways enjoy watching the "unacheivable" being obtained

Very well played, Jeff... quite efficient use of space.

Man.... your like an old watch maker....:gj:
BTW what are you reading at 7mW...:thinking:

Great job on that. I thank DTR put two drivers in one of my pen host but I don't thank they was heat sinked.

7mW is my noise level on the kennometerpro it used to be 15mW.
so now it's between 5-7mW after trevor did a software update.

maybe I need to get one of your 2.5 watt meters :thinking:

I really don't have any thing good to say about the kennometer as the support help from ken sucks hind tity, this is my second one the first one that I payed full price for came un-assembled and after many inquires to Ken I still don't have a schematic to assemble it with. he tells me every time I contact him to send it back and he will put it together for me but I'm not letting him solder on my stuff, I want to do it. I tell him that and he says he'll send me the schematic but I have yet to see it. this since he first offered it, what over a year now.
so I bought this one second hand before you came out with your more powerful model and it's as noisy as a badger in the hen house.

I'll save some cash and get one of your new models :beer:

Does the reading hover between 5 and 7 milliwatts? If it does, that's something you can fix by pressing the Zero button. The +/- 2mW after that is attributable to air currents.

My Kenometer USB was prettymuch the noisiest Ken built and my code stabilized it to to within a milliwatt... ><

I guess I was not one of the builders he asked.:eg:

Great job though. looks very professional.:beer:

Yes I have put dual sinked drivers in a 14650 host before but in that host I sinked them back to back.

It looked like this.

Well how about that you can learn something new every day, and I been hitting the reset to try and clear it to zero.

but what is funny is the display reads peak, average and minimum.
with 0mW in the min column when I hit the rest button minimum goes to 5000mW
and if I'm taking a reading and I push the zero button it quits accepting the laser
beam, it doesn't matter what button I hit after that it will not take readings any
more till I turn the power off and back on again, that's messed up

Well... good to know you can zero it now.

I've introduced the ability to reset the zero level by holding down the Zero button in LumenOS. It was going to take a significant rewrite to modify the original firmware to do that though, and I wanted to keep the upgrade free. :undecided:

LumenOS is actually rewritten from scratch. Hoping to get that released soon, but beta testing is going slower than expected. ><

Are you sure the buttons are functioning as they are indicated...:thinking:

The defective Kenometer Pro that we completely modified that CDBeam
was sent as new had 2 of the buttons mixed up..

After our mods... it now has ZERO hovering with no Laser input..
It is a solid ZERO... as it should be...

Sounds like he just meant that zeroing the meter with a laser directed at the sensor will make it start to ignore input (because the zero "level" is set so high).

Jeff, if you like I can put together a simpler solution (for resetting the zero value) for you than installing LumenOS.

...also, not pressing the zero button while metering a laser could work too I guess. Still worth a fix though.
