Picked up a PHR-805 diode from Cajun Lasers for just $9.99 along with some other stuff that I needed so I decided to do a quick 405 pen build. Once again, clif is top notch when it comes to getting things out in a hurry and the customer service is second to none, even got some goodies with my last order ;). This build uses a Groove 2 driver set at 140 mA for a nice long lifetime, and is powered by 2x 10440 li-ions. Here are a few pictures of the set up:

I used a standard leadlight host that had been in my drawer forever, a bit worn but perfect for a pocket laser

It is worth noting that these PHR-805 diodes have a different pinout than the PHR-803's or 12x's

The driver assembly: before I pressed the diode into the module and wired everything up, I heated the module up on my soldering iron until it was hot enough to take a nice blob of solder,then I filed this down until the module fit nice and snug in the pen host

First LPM run: I expected to get about 110-120 mW, so I was pleasantly surprised...

The obligatory beam shot: it is hard to see in this picture but I decided to go with a fixed focus for this build. To do so I just removed the focusing knob from the lens and pressed the module a bit further than normal into the host. then I adjusted the focus as best as I could to infinity and pressed the front cover onto the end.

All in all I think this build costs around $40 to complete, thanks for looking!

Awesome job! Almost the exact same set up as I have! Except mine's focusable and in the black host. But I'm actually about to buy another leadlight to do the same thing you did which looks to be fixed focus!
Anyway awesome build. +1 rep ASAP!
 
It is being used as the positive contact for the driver through the host.
 
Nice and cheap build. Amazing wavelenght. quite perfect :).
Are you using the 3,7v aaa sized batteries?

Forgive me for the noob questions but I'm building practically the exact same build right now and I feel like yours conflicts with some of the information I currently have...please let me know if I'm wrong.

I was under the impression that I should be setting mine over 120 if I want it to last?

Isn't the case pin on the 805 actually the negative lead also? and the bottom insulated pin is not used? It was my understanding that the 805 is case negative meaning the case pin IS the neg pin and transfers the current to the driver without the need for anything hooked up to the D- input on the groove or to the 3rd diode pin...
 
One should have atleast one such laser which is always there for you.. :gj:
Love this build +1
 
@thedude, the "not used" or case pin goes to the V(-) with
the groove 2, keep the current <120 mA , had to replace
the diode after a couple weeks, couldn't handle the current.
Hope this clears it up for others, 120+ mA is not safe IMO.

That is a 660nm diode. If you want case neg. for 405nm PHR your going to simply fold the case pin over to the negative pin... Caution though you must use a driver with a continuous negative rail. The groove2 is a very sweet driver. I miss these builds I have a stack of PHR's waiting for that X-boost.

I was under the impression the 805 has a case negative pinout same as the LPC 815 and so connecting the "unused" pin is only needed if running an 803...please correct me of I'm wrong
 
Sure hoping one of you guys can help me...I got my first build all soldered up and nothing...
So I check each connection to see where the issue was. Finally I connected the negative side of the batteries to the aixiz module and voila! Beautiful purple light!...
so the next step was put on the back end of the battery cap and try connecting the inside of the host body to the aixiz...nothing.

For some reason my battery current is not running through my host...Before soldering the driver or diode I put in the switch assembly and tested the voltage running through the host to the switch and it was working just fine.

Any help would be greatly appreciated
