Defiant Mitsu500 Pen

Hi Folks,
Hi just wanted to share a pen build that was fun to do gotta love these small builds. I know the Mitsu is capable of high Wattage out put, but this one i kept at a conservative load. Hope all enjoy as much as i did.
Inside is;;
Mist 500 diode
X boost set to 860mA
1 Efest 10440 cell and 1 dummy cell i made from AL bar stock insulated with electrical tape. Works great and looks good to
G2 lens which i changed to a 3 element lens for divergence purposes

Very impressive! It's hard to build into small hosts like that one. Gotta love that red-orange 638nm color!:drool:

Anyways, whats the duty cycle on that like?

Curious why you decide to use a boost driver. The 10440 is a 3.7 volt, isn't it? It is a nice small build.

Hi Phil,
Thank you very much for looking at my pen build.
I like small intubate builds for a change from large mass heat sinked builds. it takes a lot of time but it's worth it. Modifying a small host for a laser diode makes you better at building a better laser in my opinion. thanks again buddy for checking out my stuff.. If you need help PM me ant time.

At Paul,
i like to use a Xboost on diodes that either use an X boost or XDives drivers . it all depends on what i have on hand .
If i use an X Drive then i can use 2 cells for this diode, the same goes for the Oclaro 700. but the 500 is more forgiving in terms of how many mA's you dish out to the diode..I could have set the driver to 1.2A or 1.3a to get over 1+w's but i opted to go low this time.i have a few builds that go over 1+W's for a 638nm diode. sometime you need a change brother..

I have a question. How do you managed to get the module inside to host? A press fit?

Fits right inside the pen. I've built a bunch too. Actually have a few special bead blasted ones I haven't built anything into yet and plan on picking up a couple more at Home Depot next time I'm there.
Nice unit and it is kind of funny that you chose a boost but I've done some funny things too that have been questioned. If it works it works. Makes it easier to fit everything with one cell and the aluminum spacer.
Yes 10440 is a 3.7V/4.2V.
Bh the way, if anyone buys a piece of aluminum rod which is very inexpensive make sure you DON'T grab the anodized ones by mistake as both places that had them here (lowes and home depot) had them mixed in with the aluminum ones. Anodized aluminum is not going to conduct.
Can't REP you yet

@ Hibro,
Well first i cut the AL back half of the module just enough that when i screw the battery tube on it presses the module up against the front of the pen . The inside of the front piece needs to have the anodizing removed with a dremel bit to ground it to the host.

Hi Pman,
There very scarce around here so when i see them i by a half dozen or more of the pens . I don't even see them online i think they are phasing them out so i scoop them up.
And about the X Boost i used well it was the only driver i had at the time, to where i could have used a regular X Drive. You bead blasted yours sweet, i'm going to try different color spray paints then hit them with a thin coat of Poly clear coat for durability.
Hey even with the 1/4in rod being anodized it will not effect the current because the two ends are cut bare. Oh and thanks for the update that lowes has them i didn't look there but i will now Buddy..Once i get all my drivers in i'll be doing a PL520B 1 in those pens.And i still have a 209 sled for a 405nm build..

I ran both my oclaro and mits with a buck driver. I first used two cells before i knew much about forward volts. I actually got higher output with a single cell

Nice work Lifetime17
Black and orange-red look awesome together
I (had) a Oclaro in a Hugsby it looked awesome.

Hi 10,
Yes i usually use an X Drive , but thats all i had to work with and i had the building bug that day . Just wanted to do it, so i dug up an X Boost driver and applied it. I to run my 638's with two cells , and it all depends on the hosts structure to.

Rich

Thank you BBB, you do great builds also buddy, it's nice and clean 638's i never get tired of but divergence is another story. Over all it's a great stand by diode for one of those weekend morning builds with a cup of good coffee.

Rich

Are you taking those pics at gym room or it is you home?

It is possible someone could get a poor connection depending on how they cut the anodized rod so I was just being overly cautious and of course you could just scrape it off. Just don't want anyone buying it and measuring it on the sides or one end and a side and getting confused. Should have explained it better. Definately don't buy it and assume the anodized outside would never short out to the inside of your host. You would still want to cover it with tape or heatshrink tubing. Hopefully that explains it better

Hi Pman,
OMG i didn't say that i cover the outside of the rod with electrical tape, i'm so sorry for that Brain fart buddy. Of course yes i do insulate the outer surface of the rod. And when i was referring to the ends i was referring to the cuts after measurement of the length ..So basically the anodizing will not affect the grounding or any chance of a short. Thank you so much for clarifying this pal. Good Man Pman !!!

@ Monkeydan,

Yes this is my gym at my home it's right behind my work shop. I lift and lase. LOL !!

Oh and by the way i would like to thank the awesome moderators for deleting the but holes spam on my post. Love you guys
