I built a 1 watt blue laser in a survival laser S4 host but I managed to LED the m140 while putting it together. Just a few days ago I got the replacement diode and driver in the mail. I put it together last night and i am happy with it. I am also really digin' the Survival Laser driver. I can put in one 18650 and get a lower power (few hundred mW's) and a crazy long duty cycle or i can use 2 RCR's for full power. these pictures were taken on low power because the RCR's are still in the mail.

this picture was taken towards the aperture.

this was taken towards the 'dot'.

Which Survival laser driver are you using? I just ordered a 1.4 host bundle to build something similar, and it's got the 1.5Amp driver.

Blackwolf congratulations on your new laser, you have to go through failures a couple of times or more to gain experience unless you have electronics experience coming into this hobby. I have a M140 build I did several weeks ago with parts from SL and DTR, be careful with that thing I almost started a fire yesterday trying to kill a spider.

SquiRoFL you made a good choice, I assembled a M140 with the Survival Laser 1.4 host bundle and am very pleased with it. You can take a look here: http://laserpointerforums.com/f65/assembled-m140-c6-pic-heavy-83543.html
Get more than one pair of batteries because you may be disappointed with the short battery life unless you got the extension tube and are using 18650's, works fine with 16340's just short battery life.

I am using a 1.25A driver for longer run times and diode life.

I definitely did order the battery extension tube along with the 1.4 host bundle. I actually ordered the host bundle and opted for the (cooler looking, IMO) S4 body and the nickel plated brass diode module (which I now might regret getting instead of the copper, as this is a pretty high-end diode)

I also ordered 4x 16340's + charger, 2x 18650's + charger so I can have a shorter, more portable laser if need be.

Also regretting getting the bare diode now that it's arrived. DAMN those leads are tiny. I'll just have to get a coworker from my previous job to solder some leads on it. He's really good at really, really small connections, he can do SMD work :)

And what actual output would I expect to get out of this thing with 2x 18650's in it? I was thinking somewhere above 1.5watt and closer to 2watt? I lack a LPM so I very well may send it out to someone with an LPM to test it.

And how short of battery life are we talking with 2x 16340's? a matter of minutes before the thing dies? I did order two sets of these, so I might be okay...ish.

if you are looking for longer lead wires on your diodes next time you should try dtr. with him you cant go wrong the leads are like 2" and they come standard in a copper module. I get good run times with my trustfire 16340's. Also I think to get to/exceed 2 Watts you need a "G" lens and a 1.8A driver

I did order from DTR. He shipped SUPERfast, but I didn't realize at the time that the one that was 11 bucks more also -would fit- into the Survival heatsink as well as being pre-soldered.

Will be ordering from DTR again. Great shipping, and managed to get it in before labor day so it arrived yesterday!

i'll do a battery test tonight. I did record some data a few days ago. the batteries were at 4.24V (batteries were almost done but my parents had a fire so i forgot to check them). ran the laser for about 1min30 (put holes in a guitar pic melted soldering wire ruined a "black back" ps1 game) checked the batteries and 4.16V. since then it has been run for about 5min (beam admiration lighting fireworks killing bugs scaring a mouse onto a glue trap) I'll check the voltage when i get home. I still need to burn the front wrappings off all the candy bar wrappers in a vending machine then it is back to wavelength collecting (the purist of all laser based activities).

I am excited to See some pictures with the RCR's Please keep us posted! I am building virtually the same laser ATM with a different driver, the X-Drive. But you seem to think this driver is good. Which one is it?

they are at 3.73V I'll take some beam shot photos as soon as the batteries are full

VERY nice beamshots. That's with 2x 16340's I assume? Not bad at all, makes me even more okay with my splurge to get the 16340's as well as the 18650's. Mine will almost certainly run a little bit less time on the smaller cells, though, as I -am- pumping 1.5 amps to the diode.

yep that was with both 16340's in the time it took to take those pics my batteries drooped .6V

Good choice on batteries chargers and extension tube. As for output something in the area of 1.5W with a 3 element lens and probably about 2W with a G2 lens would be typical. Of course that's with fresh batteries, the output will be the same with either kind of batteries but with the 16340's I get a power drop after only a few minutes, they are most of the way discharged after only about 6 or 7 minutes of use.
