NEW FUNDS SPENDING
A round of BLF tech developer support, as token of appreciation and hopefully speed tech development up even more.
$30.30 (received $30) Toykeeper for example: trunk : Code : Flashlight Firmware Repository
$30.30 (received $30) Tom E for example: Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light - #2 by The_Miller
$30.30 (received $30) DavidEF for example : Another little driver that won't be much use to most of you guys
$30.30 (received $30) Texas_Ace for example: Texas Avenger "TA" Driver series - Triple channel + Bistro or Narsil + Clicky or E-switch - The Ultimate open source driver!
$30.15 (received $30) Mike C for example: Mike C drivers: v8 series, ATtiny1634 based.
(More tech developers were contacted, not all reacted, not all accepted, so the token of BF appreciation was bigger for these 5.)

Thanks for the donation. I’ll use it to build a couple of drivers for a GAW when I’m 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 :slight_smile:
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. :slight_smile:

That’s not a bad idea at all. I’ll figure something out.

It’s actually The Miller’s idea. I tried to decline the donation but was talked out of it. Doing a GAW was the perfect solution :slight_smile:

So Miller talked you into giving your donation away. I’ll have a few words with him for you and give him a good piece of my mind. He wont be doing that again. :stuck_out_tongue:

Thanks for the donation, The Miller! :money_mouth_face:

Mike C, I didn’t 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 you’re actually the guy responsible for a lot of the coolest ideas, like 3+ channel drivers for better efficiency. It’s cool you’re going to “give back” 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. I’ll try to make sure whatever I do is a push forward for BLF somehow. I’ve learned so much in my time at BLF, that I can’t possibly pay back for the knowledge I’ve gained. I wouldn’t even be doing these kinds of mods, or designing my own boards, if it weren’t for the inspiration and encouragement of my fellow BLF’ers.

I’ve already got a GAW going right now (gonna end today). So, in an effort to “give back” my donation, I think I’ll try designing another crazy, cool, or niche driver board. My reasoning is that it’s the guys on the fringe, making the niche items, that push most crafts forward in life. So maybe I’ll find another nifty host and make a driver for it. Then, if the build goes to plan, I’ll 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 don’t know when I’ll 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. I’ll 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 “Q” it needs 4 emitters :smiley:

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 70.2’s it should easily surpass 15k lumens, with xhp70.2’s 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 Djozz’s 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 “cheap” by BLF standards even if it was the best bang for the buck around.

Honestly, if something, whatever it ends up being; is the “best bang for the buck”…. “BLF standards” may have to possibly change a bit. :slight_smile:

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 anyway… & I am far from being a monetarily rich man in saying that. :wink:

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 around…)

Liquid cooling is way overrated. You still have to transfer the heat to the ambient air and liquid doesn’t 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: Joule–Thomson effect - Wikipedia

If you have a towel and a pressured gas can, try this if you did not. It is very cool :slight_smile:

If we want this, of course we would not want Butane or Propane :slight_smile:

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 won’t 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 :smiley:

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.
