My Monster 6+ watt Laser Build Has Started !

No, not other than the odd lens in my 150-200 lens collection, the 3 elements I have a dozen of are actually 31mm when removed from the holder, I call it 25mm because that's what's in the clear when in the holder.

However that 3 element set clips and the further the focus the more it clips as you push it away to focus further out, we need a more aggressive grind, a spherical grind perhaps.

Really just use what we have and the 3 element and sanwu 3X, that RX is pretty good, it blows the 2.5-3.0w NDB7875 away in reach and burning power by far and away.

I would like to see a 25-30mm long FL lens and housing, maybe even an anamorphic primary that is mounted on a can that you screw in until it bottoms out on a threaded ring that you can adjust so that you reshape the beam but leave it positive as far as divergence and then your main lens has a long thread range to tune the focal point.

But this is daydreaming, the average buyer wants a blue one and buys a thor or whatever is 59 dollars on flebay with lots of lies, I have 2 good solutions, #1 use a 3 element and sanwu 3X.....#2 use a G2, 6X Cyl pair and sanwu 3X

If someone would order wider modules and lenses, someone who knows how to calculate the needed grind, I would buy some, I would like to build a ring of 8 or so diodes in heat sinks that are articulated and align them to galvo mirrors that I could converge at a point.

Really a wider housing with a long FL lens and I would just converge a bunch of them, it's how much do you want to spend, the less you can start with the better, maybe soon it will be time to converge a dozen 7875's each with a 3 element, have you tested any, 4 of the 7875's with 3 elements will give a corrected and lensed up 44 a good run for a ways, really a dozen BDR-209's all converged, but any way you go it's 1000 dollars plus, I wish next month we would see an economy projector with 1 big SOB blue diode, I will find some lenses to make that sucker work and we are talking 600 dollars with some possibly repurposable optics.

Sorry I am rambling, go with a 3 ele and 3X, it works pretty good for 0-30 feet, or as a 3rd option you can use a G2 and the 6X cyl pair and leave the BE off, it's nice to have a fixed focus burner that works, that's what a laser should be in my opinion, ready to go as is.

No that's ok, ramble away because the more you do the more I learn !

the only laser I've tried to play with is my Americanised Thor M II which had a M-140 diode and I was trying dif lens which were one of the G2 and a couple of 3 elament lens.

as of right now I'm in the middle of changing the Americanised Thor M II M-140 into a 2 watt M-462 diode.....

Well this laser build is no longer going to be call the "Green Monster", I'm changing hosts to this one !





It can hold 2ea 26650 Li-ion batteries ! Mow Power, Moe Power, Moe power !

I think this is a better looking host, should make a fine build, and one sweet looking unit! Waiting for the unveil. Fingers on the :drool: button.

It looks even better with the Intel heat sink installed ! :wave:





Plus the threads on my host look better than the threads in those stock pictures..........

You know; for sticking a CPU heatsink on the end of a flashlight body, that actually doesn't look too bad. Good on you for being resourceful!

Your right, it does!

While I'm waiting for parts to show up I'm also reworking my Americanised Thor M II and I'm installing a M462 2.0 Watt 462mn Diode, But the main rework is the battery section which I'm heavily modifying to take 2ea 22650 li-ion batteries which is a big jump up from 2ea 16340 li-ion !

I also have a pair of IJOY 26650 40A 4200mAh Li-ion batteries on their way ! Here is the specs........

The new king of high discharge 26650 batteries is this IJOY 40A battery. This is the best 26650 size battery for high power lights and e-cigarettes and other very high current applications. The voltage drop is very low at high C rates, much better than any other 26650. Until now if you wanted this great battery you would have to order from overseas, but we have them in stock in PA.

Up grading the power with my thor M II, Huge Battery size Ungrade !!!

Interesting idea, that's a heck of a step up. You won't be rechargeing those very often. Thanks for the head up about them being state side I might look into some myself. :thanks:

Nice work, even for a guy with a thumb that bends backwards. Rep when I can.

I've done all the modding with just hand tools and a dermal, A lot of cut, grind, press, And some more cut, grind, And press, Talk about doing it the hard way !

Yea, but that's the fun part, seeing if you can

You forgot the other part.....

seeing if you can, with what you got at home !

To true!! Haaaaa

It's a challenge to hold 1 laser in each hand, balanced on the window seal and keep them both on target, I do it but combining 2 diodes would sure make life easier, then we could double wield twice as much.

It's a continuation of making it work, I also build stuff with very few tools, no lathe, no milling equipment, but I can find a way and dual wielding 5W lasers is another way of getting more by finding a way, and it's fun as well as challenging.

But seriously I want a lot more horsepower, lets get our " make it happen " heads together and build some fun hobby toys for our safe enjoyment, that will scare the hell outta the girls.

:lasergun:


Notice in this video how I fumble on the 1st one then I do better, but I do have a little tripod in my way so I can't get my elbows in there as usual.

RCB, some time back I was thinking about a way to make a three headed laser pointer which had cables, or some other kind of mechanism running to each head, if cables, they could pull each head on a swivel to adjust from a close, to a far cross-over point. This would triple the power delivered to one spot. Wanna build that? Might be better just to knife edge all of the beams together, but I thought a cool idea for a laser pointer. EHgemus agreed to build it for me but I kept getting kicked out of the cue by other obligations to the point I cancelled.

I built a triple NDB7875 and had a pair of adjusters to adjust the 2 outside lasers onto the middle one, it works but is not as convenient as a NUBM44 with a 3X BE and gets about the same results, the NUBM44 is about 2.5 times as powerful as a NDB7875 in the real world and the beam size is about the same at 75 feet between a 7875 with a 3 element and a nubm44 with a 3 element and 3X BE.

Three NDB7875' with 3 elements and 2.4a drivers is about 250 dollars while a NUBM44 with a 4.5 amp driver and 3 element + 3X BE is 190 dollars.

So you get about the same result for less money that's a lot less fuss to manage by going with the nubm44 and 3X BE. Now put the other 60 dollars into a 6X CYL pair and you have a better burner all the way around.

Maybe a ring of a dozen NDB7875's with 3 elements in simple articulated mounts like the angle iron swivels I used before with 660nm reds and the total power and ease of simply converging them could save money and build time as 4 x NUBM44's would have to be combined and corrected and both PBS pairs knife edged, only the operation would be easier usless a audrion driven galvo system was used.

I still would like to build a ring of about 24 BDR-209's, but I am really waiting for the next gen projectors, I am hoping for 1 big 40 watt diode.

Also a dozen 7875's and drivers/ect or a quad combined/corrected 44 build are both going to cost well over 1000 dollars, I would rather build a 60w C02 or a 50w, you have to pay attention to the beam spec, sometimes a 50w is much better than a 60w and 100w tubes are too expensive, a 40w or 50w with tight beam specs could be run off a ZVS driven flyback regulated by a DC to DC like that Chinese fellow built, I bought ZVS switches, flybacks, and some DC to DC buck/boost boards but never bought a tube, I'm really hoping for a larger blue projector diode to play with, if it's a GBall then I would have several ways to deal with it keeping the GBall intact.
After all the bright visible beam is part of the fun.
