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.
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 I thought you are all about real guns, which is a good thing imo as air guns are JUST waste of time.
An airgun is a lot cheaper to plink with now days sadly. Even .22 is not what it used to be. Although these particular cartridges actually came from my paintball days. I had a few pistons and other guns that used 12 grams and ended up buying them in bulk to save money.
My 5.56mm AR-15 with silencer is a lot more fun and more practical but sadly for the cost of a single round of ammo for it I can fire off a hundred BB’s or several .22 rounds.
have a small tube running through the heatsink that you can spray an upside down can of computer duster through (r152a…. 1,1, difluoroethane) to allow for a crazy direct drive turbo hehe.
Good to see the fund broadened to driver development
One-button UIs like Biscotti are very handy for blind people like me. I wouldn’t have access to anything like the range of options I do, if it weren’t for the driver developers here on BLF.
There was a discussion on various battery pack configurations and how some are more efficient than others.
I got interested and wanted to quantify what is more and what is less efficient.
I modelled battery pack volume vs capacity.
Assumptions:
there’s 0.5 mm between battery and flashlight body
battery tube is 0.75 mm thick
if there are several batteries, there’s 0.5 mm gap between them
with xx650 batteries, battery tube doesn’t fit xx700, just xx650. DQG Tiny is an example of a design that gets shorter with shorter battery.
2-, 6-, 8-, 14- cell packs are 2-cell long
all battery tubes are round. Rounded-triangle or rounded-square would be more efficient in 3/4/6/8 cell configurations, but that’s not what I calculated.
Results:
Legend:
N V -> volume with N batteries
N E -> capacity with N batteries
N ee -> efficiency (mAh/mm^3) with N batteries
I wonder why 3×18650 isn’t used more. It’s quite good.
Where do you show which shape on the graph goes with which battery size?
My spreadsheet skills are too low to visualize this. The way I set it up even hints in the spreadsheet are useless.
What I do to locate a certain point is 1) identify the data series by looking at clear outliers with the same symbol (which is a column) here. 2) look up the size in the column.
I do not suggest others do this, but rather I’m looking for suggestions. I can upload the raw spreadsheet if anyone is interested.
I should have noted: Pareto-optimal (size vs capacity) packs are bolded. There are quite a few…

No need. All I meant was a list like: “square = 18650, triangle = 18350, circle=16340, etc.” for the graph.

I’m not sure what do you mean.
Though I should have noted one more modelling assumption: battery tubes are round, regardless if they contain 1, 3, 4 or 7 cells in crossection.
I may draw the shapes tomorrow to make it clearer, though my paint skills are terrible.
And I see that symbols on the 1st chart are different from ones on the second. Will make a cleanup tomorrow.

Now I just don’t even know what you’re talking about. Draw the shapes to make it clearer? I just want to know what those symbols represent. You made those graphs with the symbols already there. But what do those symbols stand for?

I added a legend to the charts, normalized symbols and updated the previous post. Hope it’s clearer now.
I added 18350 too, it took pareto-frontier from 1×14650.

30Q cells, 16,87 (received $16.70) by DBSAR to order 4 high drain 30Q cells for cell vent testing and take them through the worst people can do with them, very useful information with the ever growing list of lights with cells in series.
.
explanation, DBSAR is about to make videos for a new round of cell vent tests. It is funny and educational to see him abuse old and weak cells in a controlled situation. However with series lights like the GT and possible future projects people will use new and/or high drain cells. So many new members, so important to see what happens in worse case scenarios with good cells.

another nice thing, with Thijsco and Cawi we are now sketching how the Q16 could be made. We called the Q8 a “SRK type monster flashlight”, well lets say the Q16 is supposed to become a monsterly beast of a flashlight
More to follow when we have things clearer but no worries, yet again a driver with challenges that is already clear to me while there has been NO talk to driver gurus yet
In due time we will start a thread on it, first getting the Q8 to you guys of course, till then the Q16 is going relaxed and slow behind the scenes.
I am looking for a mid size thrower and this is the group that can help me I think. I have an Acebeam T21vn that I run with two 18350’s and I love the 500k lux output, but I hate the UI.
What I would love to have is an SRK style light running off four 18350’s or maybe three or four 26350’s with a T21 or better reflector that would give me 500-600k lux. The main thing for me is the size of the light, it needs to be pocket-able. A 3” diameter and 5 1/2 – 6” soda can style thrower would be a unique light would be small enough to always take along and powerful enough to light up things beyond the reach of my general purpose light.
Is this possible and would anyone else be interested in something like this.

The Courui D01 uses 3 18650 cells (parallel) and feels really nice in the hands IMHO
And yes please say what the shapes represent, that would make it easier to understand

In that graph above, you have blue squares and yellow triangles and red triangles, etc. Which cell does each of those shapes represent?

Sorry grammarlovers, I am a real King Typo.
I guess there should be (pc-) fans for use in industrial environments that can withstand water, oil and the like.
More of a guess tho, don’t have any sources.
The problem is that PC fans will most likely have a voltage of 12V.
Most 12V PC fans run fine on 5V, only slower, so 6-8.4V should work.
Yes this is the idea

12V is max, most will keep running down to about 40% voltage, just slower.
