What did you mod today?

Hey :sunglasses: nothing fancy for me just pulled the Osram from my new Tool and popped a N219B behind the TIR.
And the Osram made its way into a single mode loaner light :innocent:

I managed to open my Sofirn SP36, as written in the SP36-Thread

I used a bended nail and the driver popped out after the first hammering.

At the risk of offending any copper purists out there - I plated my BLF Edition A01 Copper with silver.

For no particular reason other than to see how a silver patina would eventually look :sunglasses:

Ohhhh pretty. I love the soft shine of silver.

Over time I expect it will look like an old dime vs an old penny.

…and would likely smell as bad (eggy/sulfury).

I’ve got actual silverware, and not only is it a pain to keep polished all the time, but even spotlessly clean, it still has a bit of a stank to it.

Opened my brand new GT Micro and put an Osram Black Flat.
Went from 40kCd with the stock XP-L HI to 105kCd !

No need to say I LOVE my new pocket thrower !!!

Nice result! Stock driver? Is the 14500 limiting it enough so that excess current isn’t an issue? (edit: I was thinking of the White Flat, but I’ll let the question stand) And looks like not quite enough room for a 16mm MCPCB?

Too bad the D1 doesn’t focus the White Flat very well… that would make for a sweet pocket thrower (having the extra capacity, but similar footprint).

Cool, congrats on that GT Micro build. I kinda wanted to be one of the first to do that but of course I still don’t have a Micro GT…

Maybe I can be the first to put 7 White Flat’s in an E07…

That's a sic amount of throw for such a little light. Whatever they did, I think they got the reflector right on this one. I got an opened Micro and 3 black flats laying around. Hhmmm...

Installed a TC20 driver and xhp70 mcpcb in a Catapult V6. It’s a very straightforward mod, I made a custom centering ring with a 3D printer

It now throws +60.000cd. What a beast!

I’d love to try a mtg2 but I can’t find a mcpcb bigger than 26mm diameter

Some beamshots of L6 ashperic doesnt look right.
Edit: the spacer needs to be shorter and adjustable the same size lens are slightly different.



Nice, I have been thinking about it.
Two questions:
*did you use potassium cyanide in the process? :confounded:
*do you have any idea of the thickness of the layer?

1. He probably used potassium cyanide, yes. Unless he used a silver nitrate sodium hydroxyde solution, with silver nitrate, ammonia and sodium thiosulfate.
It does work very well, albeit slower compared to the potassium cyanide method.

2. I don’t know. What’s the surface area of the electrodes used, the current, and the surface of the A01 itself?

I have been wanting to do some nickel plating, but I’m still waiting for my nickel sheet to do it.

Sorry if I answered in his place. Bad habit of mine.

:smiley: :+1: that is the least of the bad habits that I see on BLF at times.

Wait, how did you know about potassium cyanide silver plating? :slight_smile:

Nothing so exotic/toxic. It was a physical-chemical application (electroless) as opposed to an electro-chemical application using a mixture of Sodium Chloride and Calcium Carbonate (reducing agent) and Silver Chloride (silver source). The pre-mix can be purchased commercially from Cool-Amp here.

As opposed to electro-plating which typically runs 5-10+ microns thick, this physical transfer process only deposits 1-2 microns. Just enough for a protective layer, good enough to protect and patina, not nearly enough to protect from repeated physical handling.

Sorry BlueSwordM, my anodizing and plating days are behind me. Haven’t had any thing to do with passivating or cyanide baths in over 30 yrs.

At the risk of raising more heckles from copper fans, here’s another -

Thanks for the answer. I may try the potassium cyanide method at some point but it may be difficult to find the stuff and then convince the owner that I’m not going to kill myself.

Stock driver, yes. My 14500 is a bit old so only manage to push 3,2A with the stock emitter/driver. Stayed the same with the Black Flat, but it’s enough really !
The Black Flat has to be fed with the same amount of current as the White flat, so the sweet spot is at about 4,5A.
The stock MCPCB is DTP copper, with a 3535 footprint and 14mm in diameter. 16mm won’t fit.
