Ehgemus 32650 and 2X32650 Sandblasted Hosts​



e4jdw.jpg













So here we go again with another amazing Ehgemus creation. I am sorry if this review seems a little less detailed but I have had very little time lately but I really wanted to get it posted. These two units are massive and can handle high powered builds very well. They are are a mix of polished aluminum and a sandblast finish with sweet looking rings that give the host some appeal. The craftsmanship is as I would expect from Ehgemus. Top notch.:beer:

1.7W/1.9W Aixiz/G-1 2X32650

We will start off with the big boy. This is a 2X32650 host and It is massive. This is the largest host that I have seen from Ehgemus. Being a direct press head this host provides great heat dispersal.

Here is how the host breaks down. As usual you have the tailcap, host body, driver pocket, direct press head and focus adapter.

I had decided to go with a Jib 1.8A linear driver. This driver needs a little help dispersing heat because of the high current. I took one of my gold dollars and cut it up with my dremel.

p1015914.jpg








I used the larger piece to sink the regulator and I have the coin in physical contact with the walls to allow the heat to be dissipated into the host. I used a second piece to beef up the resistors which also get pretty hot. I used thermal adhesive to hold it all in place and allow good heat transfer from each medium to the next.

Next I pressed a diode in the direct press head.

Now that I have my pill all set up and a diode pressed I wired all three leads to the diode. I used the case pin for the driver negative input. Sorry I forgot to add a picture of the driver soldered to the diode.

After I soldered the diode I closed up the module and used a little thermal adhesive to keep it closed. Then I screwed the module into the head of the host, screwed the focus adapter with an Aixiz lens in it into the head and fired it up.:eg:

1.8W/2W Aixiz/G-1 Single 32650 W/M140 diode:evil:





Next we have the single 32650 host.

I had decided to put one of the M140 diodes in this host and it turned out very well. There is not enough data to say that they are binned any higher than the A series but @ 1740mA I got 1870mW with an Aixiz lens which is great.:evil:






This host breaks down the same as the last.

Now that Flexdrives are back in stock I am ready to get some dual Flex builds going. And I am certainly stocked up.:san:

p1015938.jpg








I set up two flexdrives in parallel each set to about 875mA for a combined 1740mA.

I sinked the drivers back to back on a thick piece of aluminum. Since they are running under 1A I just wanted a little extra heatsinking which should allow the drivers to run continuously.

p1015978.jpg







Then I wrapped it in electrical tape so that it will not short out against the walls of the host.

p1015951.jpg








On this one when I pressed the diode I bridged the case pin and the negative pin to provide path to ground. It reduced the amount of wires I had to use and in turn made it easier to pack everything in the driver pocket.;)

Then I soldered the driver to the diode.

Next as I did on the last build I got out my thermal adhesive and used two small dabs on two spots on the top of the driver pocked to keep it closed. I use a small amount so that I can get it open again in the future.

p1015956.jpg








I let it sit for 10 minutes while the adhesive hardens.

After it dried I screwed the module into the host, screwed the focus adapter with an Aixiz lens into the head, threw in some batteries and fired it up.:gun:

1870mW.:eg:

Conclusion

These are some amazing looking hosts that are true performers. The mix of the polished aluminum and sandblasted surface is amazingly done and the rings give it an upscale look. I am really impressed. Anyway thanks for reading my haphazard review on these amazing hosts.:beer:

Damn! :eek: Me likes!!! :) I'm really digging the two different textures on one host.

There's an error in your post DTR. Those aren't lasers. They're art.

Ultra cool! DTR, would you see if Ehgemus would make a 3 LD pocket head with the shorter type 32650 host for my red project? ;) -Glenn

Glenn - what's your 3-LD red project? I've dreamed about something like that - but always feared that the beams wouldn't be parallel.

Well, for my project, parallel beams are not needed, each 20 mW pulsed red 635nm laser will be spread into a line w/ line generating lenses and all will be scanned over the test subject for low level laser therapy studies... ;) But I would also like one for a 445nm to just do blue beam photography as well if I can manage the cost...

DTR, what do you do for a living to afford all these awesome builds? haha cause thats what I want to do now :san:

I have these two hosts with the same set-ups. DTR is getting a bit more out of his, but they run forever ;)

And, yes. they are gorgeous!

Does a duel driver configuration differ or compare in regards to heat build up, duty cycle, and overall performance Vs a single "random" driver configuration? Curious as to efficiency of both of these hosts assuming both are configured as close as possible except for drivers.

Please don't mistakenly drop one in my package...lol


Great Work Gentleman!

DTR, you had a rest from making lasers for a while but now, Your back and better then ever :D

Beautiful work Ehgemus and DTR

I can be bothered looking around for you Ehgemus but if you post here I will give you some rep and DTR too :D

Wow these are awesome!! At some point I also want a laser in the single 32650 host :)

Great Jordan +:beer:

M140 diode? As in the replacement or in addition to the A140?

Apologies in advance Ignorance isn't an excuse ...

Those are Pretty Sweet. Almost looks like sandblasting is stone.

I like the big one.:na:
