What did you mod today?

Flashlight Modding and DIY Parts

Oh my, I hope to learn enough one day to do things like that. Skill from experience has turned to Art for you, sweet :beer:

:beer:

I am amazed at all the modding experience going on here. You guys are Good. So much to learn about drivers, I will try to keep up. It sure is tiny for 13A. You sure that may be a World Record tiny high amp setup ? Wow !! :beer:

5792

This evening I soldered a loop into one of the triple boards to check current at the emitters, each board is pulling 14.53A for a total of 58.12A, an estimated ~188 Watts. :wink: Each Samsung W6 emitter is pushing 1460 lumens for 17,526 lumens at start on 4 Samsung 30Q cells.

Makes for one CRAZY lightning show! :smiley:

5793

I couldn’t agree more with you CNCman. And that goes to the program creators for these drivers as well.

5794

Not today but added a lighted tail switch to the FourSevens Mini ML Ti Triple Nichia 219C 5000K.

LD-A4 3A driver - Start around 1800lm DD 60°C, 320lm stepdown 25s. 942lm CC 60°C, 270lm stepdown 60s.

White LED's under the green GITD silicone circling the reverse clicky titanium switch cover.

New GITD titanium switch cover for the FourSevens PK Paladin Triple XP-G2 3D.

FET 15+1 driver, reverse clicky tail switch - Start around 1900lm DD, 928lm stepdown 30s.

Fantastic CRX. Man I like that mini.

5796

Yeah that is a nice one :beer:

5797

I wish I had your smarts CRX. :beer:

5798

Not so smart, just perseverance :slight_smile: :beer:

5799

…and a certain amount of talent, an eye for detail plus a sense of craftsmanship.

5800

Hard to argue with this. :slight_smile:

5801

:blush:

5802

We would Love to see some pictures :beer: :beer: :beer:

Be careful, that’s enough amps to Weld Steel with !!!

I lost with this , I need to back up to the beginning of your mod to understand what your making.

5803

Not “today” butttt

Built a PD68 tripledown board. Still a bench project but I do have one in a light but it is just pressfit and not soldered in yet. It runs Bistro-HD right now. Still yet to settle on mode groups and actually build them out.

The cut in the PCB is intentional

This is awesome.
I believe you filed the MPCB and optic to fit into the head?

5805

Yes, MCPCB diameter just over 18mm to fit. The pill has some extra copper added too.

5806

I’m not quite ready to make permanent modifications to this light for Mrs. manithree, so I made a drop-in replacement for the incandescent bulb using a high CRI Yuji strawhat, a brass washer, and some copper wire.

5807

Looks good manithree. Hows the beam in the reflector?

5808

Nice, that will run forever direct drive on two alkalines!

5809

I was hoping to get the emitter just a little further forward than it ended up. So it’s a doughnut. And it’s significantly less bright than the incandescent which had a slightly worse beam pattern.

I have a couple of eneloop AAs in C sleeves to run it. A flashlight that old that has never had an alkine leak in it should be kept that way, IMO.

But, yeah, it’s not very bright, so I expect battery life won’t be a problem.
