Re: Easiest way to pot mod a 5 mW green laser poin I have done the pot mod to some of the early LeadLight lasers but I don't think it will work on any old green laser. To say that all you gad to do was pop off the button was a stretch. I had to totally disassemble the laer, hook it to external...

I have killed at least 6 for various reasons. Some were overdriven, some had broken connections and some for reasons unknown. One reason I suspect is just plain static. During testing I think I killed some by just touching the driver board - I now cover all the connections on the bottom of the...

I am probably going to put a pistol grip on the hex one to get that true ray gun look. KW

To answer one question sorry I don't build hosts for sale.. I have a home shop with CNC and manual equipment but don't have the time to build the stuff I want let alone stuff for sale. Both of the hosts were built from solid stock and took some time. the one with the clear cover was 100% CNC so...

A year or so I bought one of the crystal assemblies off of EBay but was never able to get it to work with my ir lasers. Probably would have helped if I built some kind if rig to hold everything so I could work with the alignment. KW

Just because I have the tools I tend to build my own hosts. Both of these are a work in progress but getting there. Hex one it a 120mw bule and the one with the clear cover a 200mw red. KW

I'm sure many people have see the same thing but the glass optics for red are the way to go. I tried it on my blue laser but it didn't do anything probably because the IR coating it optimized for red. Anyway I put it on my red laser and there is a way visible increase in output. I don't have a...

Thanks guys - spot on diode was hooked up backwards. I have wired several of these but somehow got off track. In a perfect world they would be reversed so you could use the solder tabs on the back of the drive to solder the third tab too. Thanks KW

So I just got my new rckstar driver and dummy load. I wired it up to the dummy load and adjusted to 120ma. Circut gets warm so I assume it's working. I then soldered on n 803 diode and nothing. Thinking I had a bad diode I took off the diode and re-attached the dummy. Everything tested good...

OK so I just did the test again with a proper 12v powere source. I tested the circut with my meter in series with the batteries and then in series with the diode. LarryDFW is correct the current draw on the battery was the same going to the diode - in this case about 110ma. I had always assuned...

Yes I was using a standard 9 volt battery. Thanks for the info on the current limitations of this battery. Once I get the right battery and the 1 ohm resistors installed I'll repeat the test. I live in a small town and one ohm resistors are a little hard to come by. I'll have to wait for the...

We'll don't read it then. One of those speed typing things when you get half way through and realize the caps were on and lack the ambition to type it over again. KW

SO AN ANSWER TO MY OWN QUESTION. i HOOKED MY DIODE UP TO MY lm 317 DRIVER AND HOOKED UP MY METER IN SERIES WITH THE 9V BATTERY. i ADJUSTED THE CURRENT UNTIL IT WAS DRAWING 120MA FROM THE BATTERY. I THEN PUT THE METER IN SERIES WITH THE DIODE AND FIRED IT UP. CURRENT TO THE DIODE WAS 82MA AND I...

Re: Violet Laser from HighTechDeals-Aixiz Rkcstr B Interesting comment about the static in the coat pocket. I had one of mine at work yesterday and it worked fine. I put in the pocket of my fleece jacket and when I got home it was toast. It really wasn't in a housing but all the connections...

sO BACK TO THE POINT OF MY ORIGINAL QUESTION. What is the difference in current draw between the battery and the circut and the circut and the diode. The LM317 I'm sure wastes some power just like any regulator. I have been measuring my ma draw in series with the battery and I know this is...

So I have 3 or 4 blu lasers up and running and the same number in the garbage can looking like dim blue LED's. I haven't used the 1 ohm resistor method of measuring current to the diode and generally check current at the battery. Knowing the drain on the battery is different than the current...
