: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
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:
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.
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.
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.
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:
