That's why I mentioned it.. I'm a pack rat and save almost everything.

The two open can LDs I have are from LG 18x DVD Burners. These are the two open can LDs "The Monk" was selling for $52. I'm very pleased with the deal.

Yes yes...DDL, please post back, or start a new thread of your findings when you test this Pioneer 112D open can diode!

I can see why you are happy with that deal! Thanks for the information...I went digging and found a resistor off of an MXDL and finished my MXDL 300. Here are some pictures of the build...

It was a pretty tight fit with all of the components fitting right onto the MXDL circuit board...

I wanted to build it this way if I could, since I am using the Meredith module for this one, and I like being able to remove the LD from the module for replacement if necessary. And didn't want the silicon diode and the cap soldered at the LD...

This circuit, using a 3 ohm resistor (MXDL stock), puts out 421mA. Using the Meredith glass lens, this baby cranks out over 300mW!

So, the title of this thread, turned out to be an accurate description after all!

Wow...nice work guys. Looks like I am going to have to order a couple of MDXL lights. One for a laser and the other to do that LED mod. I have gotten fairly good with these circuits, but I have yet to mount anything in a host.. ;D

You will really like the MXDL! Tell you what I'm going to do Gazoo. I'll turn out an MXDL heatsink for you if you want one. (I don't have time to do this for everybody, so please forgive) You have been very helpful, (not to mention patient) and I am very happy with my latest projects that you have helped me with. Just let me know weather you want it for a Meredith, or an AixiZ module and PM me your shipping address. My guess is, you will choose the Meredith!...
Jay

Thanks Jay...I really appreciate the offer and am definitely going to take you up on it. In fact I was thinking about asking you if you would and I would be willing to pay you. I will send you a PM...thanks.. And yes you guessed right...the meredith.

I noticed the MXDL is on backorder at DX. Does anyone know where else I can get them?

The link that amk posted is the MXDL model that I am using. This is the one that DDL posted in his original post about the DIY Laser Torch.
amk, I'm not that fast as a machinist and it takes me about 1/2 an hour to make one (plus material and clean up). So, I wouldn't feel good about having to ask about $20 a piece to make these, it would be very time consuming for me. I guess if someone really wanted one bad enough to pay $20 bucks plus shipping. But, like I said, I think it is too expensive!
Jay

Just a couple of tips on the MXDL:

The little treaded aluminum driver mount for the MXDL is already made for an emitter, so the Cree mod, is just replacing the driver and the emitter. (http://www.laserpointerforums.com/fo...num=1194770080) You will notice, that the driver that the MXDL comes with, is grounded to the aluminum treaded holder. Just take note of this circuit.

Now take a close look at the aluminum driver/emitter mount. The top (flat) aluminum surface has been removed (drilled/grinded) to allow room for mounting the LM317 and components. Use the small round circuit board that the MXDL comes with to mount the LM317 and components. Just take note of how the stock circuit is set up...which is the positive lead and so forth. You will find it easy... You could also solder the silicon diode and cap at the LD. This is how DDL first showed it in his thread linked below. Just check the amount of room inside when determining this...
Jay

P.S. DDL has some good pictures of inside the MXDL on this first page of his DIY Laser Torch thread:

Nice, i may have to make another one. I did one following DDL's thread, and looks like a DIY. Jay's looks professionally built.

Nice, i may have to make another one. *I did one following DDL's thread, and looks like a DIY. *Jay's looks professionally built.
Thanks desslok...

Well, I like this open can/MXDL set up so much, that I built another one the exact same, except with an AixiZ acrylic lens...just so the Meredith MXDL 300 wouldn't get lonely...

Here is a video of a nice match burn using the Aixiz acrylic! The distance wasn't real far... 4 feet. You can see that the matches ignited instantaneously! (except for the 2 that my aim was slightly off)

I'm sure there are many of us who answer in a similar tone to laser questions from the wife...

Default Re: MXDL Over 300mW! (LPM Reading Video pg. 2)

Hey I got some 2.7 ohm, 1 watt resistors today. So, I changed out the 3 ohm resistor in my MXDL 300 and tried it out! The new current measures at 468mA's. The power is now 328.3mW's. This is with the Pioneer 112D open can diode, and a Meredith glass lens. Just to show the difference here... When this LD dies, I will probably change the driver back to a 3 ohm resistor. It feels like the 20mW gain is not that much for a 47mA change in current. Now, if I had a really HOT diode like Gazoo got recently, then we're talking! But for the 'normal' open cans, I really think the 420mA area is the 'sweet spot', like we had discussed before...

P.S. In case you didn't see it, I'm selling these heatsinks now:
