Maybe put the emitter in a jar of mineral oil. In the center of the jar the heated oil will rise and make a thermal current to cool off the bundle of emitters. You could make a really nice camping lantern with that and a mayonnaise jar.
did i hear my name? i’m happy to answer questions about my boards if there are any. wish i found BLF earlier, you guys seem to be way more into diy than some other light forums i’ve been on…
welcome to the best flashlight forum on the internet 
Hi tterev3, I generally would like to have the creators knowledge and approval before adding links to the op even though these are already posted as shared at Oshpark. That’s not always possible but glad to see you’ve registered so you can officially give your approval.
Antoninodattola, is that a board Mattaus designed for you? If so, then great. If not, then I’d like to wait on his input in case it’s for someone’s pet project.
Hi Rufusbduck, go ahead and add mine. Here are the links and some other info on my blog (where schematics, source, etc. can be found):
MELD1: OSH Park ~
Everett's projects: MELD v1 boards and Olight S10
MELD 2: main board: OSH Park ~
SEPIC daughter: OSH Park ~
LED board: OSH Park ~
Everett's projects: MELD v2
and here’s another that’s not on OSHpark (i did it before they existed) but I’ve seen a few 4x7135 boards on this thread that would work with my code so i think it might be relevant: Everett's projects: Super RGBWUV flashlights
thanks for organizing this thread!
Hey tterev3! Welcome!
I was wondering where you sourced the UV leds you’ve used.
It seems the MELD will get a UV LED that fits on cree XQ pads. On the Super RGBWUV, might that be a “3535” UV led that fits cree XP pads?
Unfortunately uv tends to be really expensive. I’ve been fortunate enough to be able to use some R&D parts for most of my projects but if I have to buy them the luxeon UV is a pretty good part, very high power. It will fit the Cree xq pad that I have on the led board
Are the issues with Meld V1 enough to advise against ordering it or are both versions good to go?
Welcome tterev3…there are a BUNCH of absolute geniuses and artists here (I’m just the cheerleader 
), I stumbled across your build and video’s and about tripped on myself trying to find someone to invite you here to enter into the fray…with your expertise added to the pool…there is NOTHING you guys can’t whip up! I’m 100% positive on that!
tterev3, I just watched the videos- Very cool. Do you sell or have you considered selling some of your drivers?
I’d recommend going with v2. V1 has a flicker issue that can be solved, but it requires cutting a trace so small I needed to do it with a microscope. If you would much rather the single board solution, I could send you one of my v1 boards that I’ve fixed—I’m not really using them since I got v2 running. I’d let it go just for the cost of the components. Again v2 is a much better option though
I’ve thought about selling but I think the cost may keep most people away—there’s a lot of pricey components on the multicolor boards. If there’s interest I would certainly consider it though
How pricey are we talking?
I would estimate around $20 for a parts kit and maybe in the $40 range assembled
I’ll pm you to not tie up the thread. Thanks.
The name here might be budget light forum but quite a few members wlill drop a good bit of money into a flashlight.
The vias are open, I can see daylight through them, but there needs to be some kind of sealant between the PCB & body anyway so that's really not a big deal. They're a little thicker than the originals but that's a good thing - the switch bezel will clamp the PCB tightly, compared to the stock parts where the PCB floats around even when it's all screwed together tight.
Just got my 3x 7135-based SRK boards in today. They’re very nice. Not only do the purple and gold boards look great, they feel like they’re well made. I have my parts on order (though I may be waiting a little while for my 7135 chips from FastTech)
Overall, very pleased w/ OshPark (and shout outs to the board designers too).
I’ll post the links in the op if I have wifi in the next few days. Do you have parts lists for these and are you going to provide firmware or sell flashed mcu’s?
That’s a pretty amazing bit of programming in that video.
I’ll put together a parts list today or tomorrow and post it. It looks like most of you are set up to program Atmel parts, so it’s probably easier for me to provide programmed PICs, but if anybody wants to build one and has a PIC programmer I can provide the source
