Does it wick the heat off pretty well since it has a PCB rather than a copper plug underneath?
Can you get a triple XP-E one made up?
It has a bunch of vias that wick the heat through. Better than a board with dielectric layer but not as good as a noctogon. I’m know he had thinner boards made but not where. Xpe’s should fit xpg noctogon footprint. Same base with a different die on it.
The hole in the center is too small for good sized wires but that can be addressed with a drill.
Bookmarked. Thanks for designing them and putting on one page. 
Would extra solder paste on those vias help, as in a solid solder plug from the top side where the emitters sit to the backside where the copper plating is located?
My guess is they aren’t pushing 3+ amps thru to each emitter? Do they have a XPE version or are you recommending the XP-G noctigon over something like this?
I think it’s rather intriguing…but fear it might not adequately cool the emitter at higher current levels some are wanting to push em too.
Similar to this
It was designed with 3A per in mind and in fact he and Pilotptk crammed 7 XML’s onto a similar 20 mm board. Enough solder to fill the vias without floating the LEDs would be ideal.
7 XM-Ls on a 20mm board? SuperMule! (TM) Blinding in direct drive, for around 15 seconds at a time!
I have to find Scaru’s thread on that one but I don’t remember if he ever did any beam shots. It’d be a hoot to see a video of it.
I have couple of ideas for PCB designing gurus here:
8mm, 10mm and 12mm wide round boards for 4 pin momentary push buttons (button on one side and soldering points for wires on the other side):
20mm, 22mm, 24… up to 30mm battery contact boards with solder mask for clean spring soldering, like this one:
I would do that by myself, have Eagle installed but that stuff requires some serious training, not possible to get results overnight unfortunately. :_(
Also, if someone has enough time and will to arrange NANJG 105c components to specific PCB dimensions please let me know, THANKS
Sirius9, a similar idea was done by Old Lumens on a copper pipe build using a star to solder the switch. Here
Pretty nifty in its simplicity, but I like your idea, that would make things more simple for the drivers that can use a momentary switch.
P.S.: I too suffer from a lack of knowledge on those design programs.
Subscribed :-)
Switch pcb’s are dependent on switch terminal layout so a different one would be needed for each size and terminal layout. It may be that someone has already done some switch pcb’s, have you searched at all? Oshpark doesn’t seem to have an internal search function and projects are seen in reverse order of submition. I like the idea though and am certainly willing to have different subsections of Oshpark projects indexed in the op.
The momentary switch with pcb steel, it's a great idea!
I mounted one of the zebra on SC600, another life!
I tried Eagle, after a couple of hours, I was able to understand a little how it works, it is not difficult, congratulations to all the boys here!
It would make a great beginner project.
Where does one get downloads of eagle?
We are into suggestions now, right?
And I am not into Eagle, and will never be as long as I can get other people (who are far better in doing that than I will ever be) to design what I would like to see 
Ok, I would not mind a triple AA battery carrier (the diameter would be 32mm), for direct driving a modern led on copper with Eneloops. It could be something like what I picture below, but I am sure it can be thought out better than I just did in a hurry, and the better design is very probably already there somewhere. The design could be accompanied by a contact board for the head part.
(And I guess a 4xAA battery carrier would come in handy also).
I never thought of a battery pack… A 2S2P 18650 pack, that would be cool too.
Edit: I just answered my own question from earlier post. Eagle for the hobbyist is $169! That’s a lot of batteries, lights, emitters, copper etc. maybe we could commission designs for a small fee?
Oh yes, I knew I forgot something, battery carriers thanks djozz 
how cool would it be if we had 3xAA serial, 4xAA serial and maybe 2S2P because I remember looking at Sunwayman D40A battery carrier and thinking how nicely it is made, would be good to copy that design. Also 3x18650 serial and parallel and 4x18650 serial, 2S2P and parallel…
This is not hard to do (on paper but I doubt that OSH Park accepts hand drawings), and it was one of the reasons I instaled Eagle but I thought it would be like: add board, specify shape and diameter, add pads, via holes, solder mask and milling marks but after about 30 minutes I couldn’t even find how to draw a board shape I expected to see component libraries and then just drag & drop resistor, d&d mcu btu noooo. 
It’s discouraging to think that it would take me 2 days if not even more to make something that PCB gurus here would do in just 5 minutes…
If anyone has anything they want designed in Eagle please PM me and I'll see what I can do. Please note it helps if YOU have a very good idea about what you're after first. I find it difficult to get motivated if I'm doing all the thinking on a project I have no meaningful/personal attachment to. Sounds odd I know lol.
