My new TI-V2 host with Tritium






Dear Alaskan
It was sold to a member here, if you want, I can do another one,Please let me know if you want to add tritium just like in the photo.
 
3 each 36650 batteries, and instead of 70 mm diameter head like this one, 100 mm OD and 30 mm longer inside chamber.
 
Be careful what you wish for, I could do that, he made five of them for me.

Waste heat builds up really fast with two 044 diodes, I built a 3 x 7875 before and waste heat built up super fast.

How long is the run time?

yes,i have
what host do you want??

I put 3 x ndb7875 @ 2.4a into a round aluminum head that was 65mm wide and 65mm long and it was hot in about 60-75 seconds.
So 2 x 044 @ 4.5a each will likely get hot just as fast.

The 7875 is ( 2.4a @ 5v ) 12w in and 3w out for 9w of waste heat each and that's 27w waste heat for all three.
The 044 is 4.5a @ 4.7v so that's 21 watts in and 7.5w out for 13.5 watts of waste heat each so two would mean 27 watts of waste heat, the same as the 3 x 7875's I used before, so runtime will be 60 seconds from a cold start with 2 minutes cool down but the thing that really stood out was how fast it went from a little warm to hot so if not cold but only cooled down then run time might be 45 seconds, but this is just an estimate based on indoor 72F ambient temp and what I remember, but I do remember it got hot fast once it saturated.
