Arc AAA LS high dome mod - w/ pics

[d'mo]

Hey all!

With all the recent "David and Goliath" stuff going on, I've parted with all of my M*9 stuff, including a TonyB S01itaire LS mod. As much as I hated to see it go, life goes on. As a result, I acquired a "dud" Arc AAA from the recent auctions. Since it was already non-working, I carefully removed the electronics and replaced them with a high-dome LS (don't know the rank, but it's beautifully white).

The beam is extremely wide (no lens... yet) and has a center hot spot and glorious flood beam. I finished it about an hour ago so I have not had the chance to see it in the dark.

Here are the pics (I'll remove them if they are sucking up too much bandwidth). Enjoy! /ubbthreads/images/graemlins/grin.gif

the business end...

Let there be light...

Wide flood from about 8". The spot on the right is a modified Photon III with T-rank Nichia.

NICE

Any idea on the current draw? relative brightness to a fully driven 1W LS?

 

[jcciv]

so is this a direct drive? if not, what step-up module did you use?

 

[d'mo]

It's drawing about 200mA accross the diode. Compared to my old Arc LS and the naked eye, I figure about 60 to 70% as bright (when placing an NX05 optic in front of it to make things fair).

The circuit uses a Zetex ZXSC300, FMM617 transistor, 100uH inductor and .0033 ohm sense resistor.

The last two pics aren't showing up for me. It just says that you can't access these pictures outside of imagestation. /ubbthreads/images/graemlins/frown.gif

Me too. d'mo, you can host them on my site - it's up now... See my sig.

Hmm, strange. I can see the pic, though. Maybe that is because i am an imagestation member too.

Hi Dmo, any chance you would help other CPFer (esp me) to do this mod?

 

[Rothrandir]

very nice!

i can't see the bottom two pics either though /ubbthreads/images/graemlins/frown.gif

If you right click on the pictures that you can't see, you can get the url and then copy and paste it into the address box, and then just go to the page and view the pictures. I love that beamshot!

Hey D'mo that circuit sounds really familiar, did you take apart my solitaire mod already?

 

[d'mo]

Shiftd,
I'm not sure I would want to tackle multiple mods like this. I suppose I'll think about it.

TonyB, as much as I loved your mod, I sold it in protest in solidarity with Arc. No more m*9s for me...ever, in any form.

The circuit, however is from Zetex's spec sheets of the ZX300.

Back on Monday...

I'm in line right behind shiftyd ... since my soldering of teeny items is legendarily bad, could I convince you to duplicate this little marvel?

you knew this was going to happen!

d'mo,
Very nice mod, can you give more details on the circuit you used? I would love to try something like this myself.

 

[Lantern Jack O.]

D'mo, that is amazing. /ubbthreads/images/graemlins/thumbsup.gif

 

[glen]

Please tell us how you did that.
It is perfect.

 

[Gransee]

d'mo, that is a nice mod! You guys keep it up and we will have to offer the AAA2 (still working on the name). Henry and I think a small AAA LS could be made in larger than small unit quantities. Not easy or cheap though.

Again, nice mod.

Did you use the circuit without the schottky diode and cap? When I do this with 1.5V input, the 617 gets very hot. Could you give some details on the inductor?
Thanks,
Rob

....YES.....Hot Damm!....

A real AAA LS....OH yes.

Do it Peter do it.

And do the AA in an LS as well.

You make it and they will come
