My Latest Insane Project

Ok, fair enough. In my limited testing even the fancy gold plated springs can only do 15 or so amps.

+1

:D

Actually, SF does have such switch: http://solarforceflashlight-sales.com/product_detail.php?t=LF&s=41&id=198&sname=tactical&xpage=1&sh=1

Btw scaru, so far the AW IMR18650 still seems to be the way to go. We have some promising cells from Samsung and Sanyo coming from the far east, but that might take a while.

LG and Panasonic are out of this contest, no cells with according specs available and Sony have been tested and those are inferior.

Oh, and of course I will modify spring and switch. Using flashlights without any springs gives me a bad feeling about squishing them..

Thanks Nightcrawl. The S7 does have a spring and has a decent amount of resistance.

Part of the reason I'm obsessing over this so much is when I'm going to use 12 gauge wire within the drop in, I might as well reduce resistance everywhere else.

This is a knife switch, you said you wanted a switch to handle 21a, I suggest what you want is a switch that fits a solarforce host that handles 21a :bigsmile: :stuck_out_tongue: J) 0:)

Sorry, limey humour….

Ah…ahem.This has already been built and sold both in triple and Quad mule configurations.
Link? Search should be fairly easy…The players do reside at CPF

But those are triple and quad. This is 7. Huge difference! I say if you can do it go for it. :slight_smile:

In XM-L? Really? I looked around and can't seem to find any, if you can find one I'd be interested to see a link.

Over at CPF, there have been some conversations about reducing the forward voltage of LED’s by shocking them with high current pulses. I believe it was a SST-90 though.

Can’t wait to see how this project works out! :wink:

A123 LiFePO4 cells will give you much longer times above 3.1V, but max voltage will be around 3.3V Plus the 26650 cells can do over 200 amps into a short… 70 amps won’t faze them.

7 is the max for flat positions if you make a 3d board there’s more space…

I wish I could get a board like that for my 4 ez900 LEDs :slight_smile:

Why do you need all the current to go through the springs?

You could use copper braid inside them, as described in this thread:

Woaaahh. Did you say 7?

Is someone attempting to wind me up? Even the quad that was built was dead soon after it powered up.

3 is noteworthy. Keeping 4 alive and yourself is honorable.

You say 7? Even if you combined the modding capacity of Scaru & JohnnyMac you would get SMacRu....literally

When was there a quad built? I keep hearing of other multi XM-L P60 drop ins but have not seen any links or threads.

But yeah, 7 is insane. You wouldn't believe the number of people who have PMed me suggesting active cooling.

Scaru - You scare me.

Tongue Out

One request please. Find someone with a video recorder and when you turn it on the first time, have then record it for posterity. It may be the only few seconds to ever see it.

Four most well known last words in the South - "Hey Y'all, Watch This!"Laughing

Will do OL, I'll attach a note to it. "In Case of Death, Upload to BLF" :D

There might be a problem with overexposure. Try looking up techniques for filming atomic blasts, shielded underwear, etc.

here lies scaru… tried to go where no flashaholic dared to go before

but there will be one hell of a video to follow :bigsmile:

edit: first time using gimp… go easy on my graphic editing skillz :weary:

My only question is why go the whole nine yards and use XM-L2?, sure they cost more but 5% less heat, U4 equivalent, probably very slightly lower forward voltage… :open_mouth:
