Oshpark Projects

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.

Bookmarked. Thanks for designing them and putting on one page. :slight_smile:

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
:slight_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.

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!
