:bowdown:My most comprehensive build to date using the 9mm 445nm diode with a circular 15W TEC and a cooling fan. I give you.....:bowdown:​


Titan's Fist
IMAG0418_zps9c6dc137.jpg



The biggest hurdle to a TEC build is the wire path, well to me anyways so I sourced two 26mm pielters with a 10mm center for a great price. Once I received them I put together a mock sink to see if it was even worth the effort and man 15W Qmax I think dose the job nicely:wave:

It all started like this:
IMAG0261_zps48b20307.jpg


Once I had the design in my mind I drew it all out on paper then I used some of the ideas I had left over from the firefarter build.
IMAG0318_zpsc280e34b.jpg


The LED switch I ordered was a LED 250V 5A rated with SPDT. Being a automotive accessory switch there is no off/on offered on the switch, so I used my Judco 10A tailswitch mod @10A rating it was more than sufficient.
IMAG0291_zps0bb5cf3a.jpg


The thought was to run the 9mm with the TEC and fan on the first button push then just the TEC and fan on the second. So I had to use a blocking diode or just a silicon diode (1N5404) to stop the flow of current from on throw to the other (isolation of the switch).:na:

Next was to mount the switch into the host. I seen a you-tube from Old Lumination from CPF and added my own spin. The stock switch was dremmeled out and while I kept the steel ring inside the host I used it to mount 2 stainless screws to the modified switch this is a great way to use the LED switches instead of the stock mag-lite one... very sturdy.:yh:

Next is the heatsink... the most complex for me. I sandwiched the pielter between the upper (cool) and the lower (hot) I wanted to keep the drivers on the cool side like in the firefarter and so I used the same method. I tapped the the bottom of the upper sink and used some 6/32 stainless steel bolts... I came up with the idea to drill the lower sinks hole slightly larger than the bolts and then to use nylon washers to keep the bolts from wicking heat up to the upper sink.

Next was the fan. I used a Sunan 20mm x 20mm 5V .2A amp which I wired up to the TEC's driver. I also used nylon bolts and nuts to keep the heat from the fan itself... spins pretty good.

Next is the drivers... first I want to say I did not want to build this unit without consulting our local driver master builder lazeerer. Angelos, thanks man:beer: I know you bumped some folks to get me my drivers and I really appreciate it.:bowdown::thanks::thanks::thanks: I'm using his X-drive V7 adjustable continuous ground drivers for the TEC it has a 223 induction coil Angelos though it necessary, you should see it a true work of art. These are sweet drivers man, use them folks, they are that good.:worthy:

Copper module with the new backing plate being used.:whistle:
IMAG0393_zps40a86ef5.jpg




The TEC driver is set @2A right on the money and man its working hard for me.
The 9mm is running @2.4A and punishing the diode even in it's coo0ld home.


So all in all this build took about 8hrs, of course if you count on the waiting at the mail box and the time taken to think of the next task maybe 10hrs.

So here is the just of it. When the TEC and 9mm and fan are working 4.3A are being pulled from the cells I can use either 2 32600 D cells or 2 26650s. As far as a power chart for the laser I'm not even going to measure it. I only have a 2.5W meter and I can tell you right now that this is going north of that.:drool::drool::drool:

I ran a poll and it was split with 50/50 on show me the guts and hide that junk so stay tuned next week I should have a pleasant surprise for all and I have never seen it used here before... at least how I plan on applying it.:shhh::na:

In closing I will leave you with some parting shots and a small vid of this Titan's fist. Yea it's kinda heavy a real man laser as always folks get out there and build:crackup::crackup::undecided:

Now that's commitment. If you could mail that too me ill immediately meter and mail you back one that look similar ;)

Great job. I need to put some fans to use.

Can I ask where you found that tec?

WOW!

That backing plate on the module, it contacts the back of the diode to improve heat transfer, yes? that is a good idea indeed. too bad you don't have an LPM that goes that high, watching for a power drop could give you a good idea of runtime

is it possible to take the diode's temp while running? it'd be cool to see a graph with the temp increase of this build's diode over time as compared to a 9mm in a plain old heat sink. this would make visible the difference TEC offers

rep from me

True work of art Jander,

Your latest and greatest creation, the 'Titans Fist', is a testament to your superb skills and attention to detail.
Combining these qualities to bring to life an amazing work of laser art :D

I bet that TEC keeps the 9mm cool all day. Once the new 9mm 445 diodes come down in price you should upgrade :eg:

I envy all of you with a lathe. I would love to be able to make not only laser stuff but have the flexibility to make parts for anything.

Fantastic build!

Incredible! Did you get to measure the output and stability of this beast? :D

I think eBay.... worked out good gets nice and cold

Yep lots if testing needed on this bad boy. Thanks for the kind words.

Thanks for the kinds words yep more of these for the hot diodes looking for my next host.

Hard to save for the proper LPM, but it's on the list. Tune in next week when I upgrade the fist.:D

Very impressive build jander!!!
Love your attention to all the details; the whole package is A1!
The lathe work, assembly, and even the presentation and pics are very profesional looking.
Also, gotta like the ones in the grass, I haven't seen green grass around here in a long time! :)

Wish I could give you some deserved rep! Until the system lets me :beer:.

Wow.. this looks like something out of an old 1930's science fiction movie.
Masterful work of art and science combined. Who said science can't be creative.

;)

:D:D:D:D:D +1 rep when the system allows me to.

I hope you have someone here meter that beast. From what I've read on these pages the 445 diodes seem to really like being cold. What kind of temperature can you maintain on the diode in operation? + rep

Thanks again for the kind work... yep the TF needs some testing I really have it sitting there awaiting the upgrade still which is going to get the plexy glass window like TT.

Cool, I've been looking at round TEC's with holes in them for awhile for a build, where did you get yours? Price each?
