Thanks Tom, I want this to be as inclusive as possible but it makes sense to be sure that these are working systems. Is the 7135 board a go? Matt’s larger designs are based on Comfychairs work on the nanjg east-92 which is well enough established by now but the 15 mm board uses a much smaller FET that has not been tested to any great degree if at all. I have some of the IRLM2502’s coming that I hope to try on a regular nanjg board within a week or so but they were an option suggested by Werner for a very similar project(I would call it a parent project in fact) that he was(and may still be) working on. Patience not being in abundant supply around here we’ve been jamming to get these done and ready to try but testing has been mostly limited to the 70N02 FET. I would suggest that initially at least people consider these FET boards as beta prototypes until they have been assembled and played with in greater numbers.

I "think" the Z8 7135 board is a go, but no experience myself. I'm all setup with the tools and able to program both Tiny13A and Z8 based drivers, just the Tiny13A's have a big advantage right now in developed/tested firmware. Tivo did an excellent job, but doesn't have battery management or e-switch support yet. Love the ability to re-program the boards from the spring side - I've used it and it's really nice, not having to dis-assemble a pill.

Thanks for doing this! I agree - it's moving way too fast. Waiting on build/test threads of the newly posted ones. Not sure what the thru-holes are for, like in the 17mm FET - was hoping it was for programming Smile.

If you were designing a board from scratch couldn't we just reroute the traces needed to reprogram the attiny13a to through hole points as well?  I don't know if there's enough room but it seems like you could do the same thing.

I got this one from Scaru. Triple XML PCB. Work awesome with the FET drivers. I’ll have to get back to that project.

I traded him for a few of those boards. I thought they came from another fabricator as they were thinner than 1.6 mm. Thanks for the link. If Scaru gives the thumbs up, there’s a category waiting for it.

18 of the original design with no ground ring already being made.

I didn’t even notice.

I think you can make a workaround.

Maybe I’ll work the boards and stencils around to the trash can, get the new ones. Wink

Just ordered 18 of the new layout, my 6 yr old will take great delight in learning the game of tiddlywinks with the first 18.

The stencils should be fine, right? Face or FET side will be the primary as the few components on the spring side are easy enough to do freehand and can’t be re-flow soldered anyway with the other side already populated.

Another work around at least for the 17’s and 20’s would be to add one of RMM’s contact boards and using 24 or 26 solid in the vias.

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.

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.

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.

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 Smile

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.

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.

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  0:)

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 Smile thanks djozz Wink
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 3×18650 serial and parallel and 4×18650 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. Sad
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.

I’d very much like to encourage projects and think each one should have its own design thread that can be linked to here but having them mixed up here would be a mess. Matt is good at this and these are great topics for general forum discussion as they can be very inclusive, stimulating a lot of input. I think battery carriers and switch plates are am excellent idea. Try and be specific when labeling them so that those using them later get the right ones.
