Thanks for the donation. Iāll use it to build a couple of drivers for a GAW when Iām finally satisfied with the design.
:+1: thank you for creating BLF tech.
You guys are the core why manufacturers take us serious as a group with real information and input and not just a forum of consumers.
It is the likes of you that are making it possible for people like me to dare ask manufacturers to look at an idea and thus making BLF specials possible, not to mention the coolness of what gets done with super firmware, lighted tailcaps and what not 
So thank you again!
Pretty cool you wanna do a GAW! do people who donated to the funds and enter an extra chance?
Nice Mike. You receive a donation for work carried out that you will do more work and donate it away.
Thatās not a bad idea at all. Iāll figure something out.
Itās actually The Millerās idea. I tried to decline the donation but was talked out of it. Doing a GAW was the perfect solution
So Miller talked you into giving your donation away. Iāll have a few words with him for you and give him a good piece of my mind. He wont be doing that again. 
Thanks for the donation, The Miller! :money_mouth_face:
Mike C, I didnāt think I deserved to be on the list of recipients, but you sure do. Your work around here is undervalued, IMHO. Nobody talks much about your contributions, but IIRC youāre actually the guy responsible for a lot of the coolest ideas, like 3+ channel drivers for better efficiency. Itās cool youāre going to āgive backā your donation by building drivers and doing a giveaway. It reminds me of Old Lumens in a way. He had received lots of flashlights from manufacturers for reviewing over the years, and he never kept them, but always did a giveaway here.
Also, I want to take the time to say thanks to everybody that donated. I hope you all feel good about the decision The Miller made here. Iāll try to make sure whatever I do is a push forward for BLF somehow. Iāve learned so much in my time at BLF, that I canāt possibly pay back for the knowledge Iāve gained. I wouldnāt even be doing these kinds of mods, or designing my own boards, if it werenāt for the inspiration and encouragement of my fellow BLFāers.
Iāve already got a GAW going right now (gonna end today). So, in an effort to āgive backā my donation, I think Iāll try designing another crazy, cool, or niche driver board. My reasoning is that itās the guys on the fringe, making the niche items, that push most crafts forward in life. So maybe Iāll find another nifty host and make a driver for it. Then, if the build goes to plan, Iāll do a GAW of the modded light. The donation money will help me buy the board from OSH Park and the components to populate it, and maybe the host to put it in. I donāt know when Iāll get all this accomplished. Perhaps it will be done in time for my 5000 post GAW! :partying_face:
Hmm. Sounds like Miller has been at you also David. Iāll sort him out, dont you worry about that.
What you said above was very nice and Its members here like yourselves that make this place pretty dam good. Thanks guys. :+1:
Yeah, that scoundrel! I hope you work him over real good! :smiling_imp:
Is this a single emitter? How to send funds for the GREAT BLF GT project?
Well to get a āQā it needs 4 emitters 
If you donate and write GT in the note with your username t will be allocated to that project.
How can I send my donation for the "mighty" BLF GT?
You PayPal and write for GT in the note with your username and the donation will be allocated to the GT project.
Thanks for the donation here as well. if we can come up with a good design for a Q8 lantern I could get it 3D printed for testing.
For the Q16, the biggest issue here will be heat shedding. It will need a massive heat sink.
With 4x xhp50.2 or 70.2ās it should easily surpass 15k lumens, with xhp70.2ās it could get close to 20k or more.
The problem is that it would also be pushing upwards of 200-300W worth of power, which is going to get REALLY hot. So figure it will need to be quite large indeed to reach that level.
Honestly Djozzās spotlight idea that was tossed around for the GT at first would be ideal for this, it would allow for an active heatsink (aka a fan) and could actually handle that king of power.
Although it would most certainty not be considered ācheapā by BLF standards even if it was the best bang for the buck around.
Honestly, if something, whatever it ends up being; is the ābest bang for the buckāā¦. āBLF standardsā may have to possibly change a bit.
Many times quality and dirt cheap do not go hand in hand.
Sure, bargain for the absolute best price that can be achieved and then that is what it is. :+1:
IMHO anywayā¦ & I am far from being a monetarily rich man in saying that. 
Liquid cooling for the Q16.
+1 for the latern ( do anybody know where to buy the solarforce? Only to have it in my hands and play aroundā¦)
Liquid cooling is way overrated. You still have to transfer the heat to the ambient air and liquid doesnāt help that much. You still need a lot of surface area to do that.
Yeah. While liquid cooling is better than active air cooling it is not worth it because you still need fans with liquid cooling.
I have a different idea.
Did you put pressure on tip of these pressured gas cans before? If you did, you probably know that they make extreme coolness. I do not know if this is practically implementable but think about it.
Here is some science: JouleāThomson effect - Wikipedia
If you have a towel and a pressured gas can, try this if you did not. It is very cool
If we want this, of course we would not want Butane or Propane
Look at this: Amazon.com
There are refillable CO2 cartridges for air guns. They are available in everywhere, especially in USA! Even though they can be refillable, they are also very cheap.
I do not know cooling performance of these CO2 cartridges in terms of Joule-Thomson effect. These cartridges most likely do not provide enough temperature decrease for these kind of lights. But this is just an idea and we need to fix this heat issue somehow or there wonāt be q16.
This Joule-Thomson effect also makes the basis of some air conditioners and refrigerators . (US7254959B1 - Joule-Thomson effect air conditioner using air as the refrigerant - Google Patents And I do not know why but it got patented quite recently though.)
Heheh dry ice cooled flashlights
Giving light, lots of smoke effects, we need the thunder and lightning stove then
While a Co2 cooled light would work it would take a LOT more then 12 gram cartridges (of which I happen to have 175 of them for sale if anyone is interested).
A 12oz Co2 tank should keep it cool for awhile though. A more practical option is to use the heat shedding abilities of evaporation to cool it. I ran some tests and it takes a surprisingly small amount of water to keep a lot of heat cool. As it evaporates it removes a LOT of heat. Although you would then have steam pouring out of the light and have to fill it with batteries and water but it would keep it reasonably cool.
That is why we have 2 hands
Btw off topic but why would a Texas man own an airgun? Come on man you are not Canadian :laughing: I thought you are all about real guns, which is a good thing imo as air guns are JUST waste of time.
