What did you mod today?

Thanks, those should work according to the specs. I appreciate you looking.

But I did end up modifying the XP centering rings successfully. I got around to switching in XHP50.2 emitters in my 7xC8 light . After a few short bursts with some old liitokala 26650s 4 of the 7 XHP50.2s have 2 dies dark. All the emitters came on MCPCBs from mtnelectronics and are well sinked to the aluminum plate with thermal compound. It should be less than 5A per XHP50.2. I was aware of this issue with the XHP50.2 (half the dies going dark) but I guess I thought I would get lucky. Bummer… :weary:

Not really a hard mod to say, but right before I was going to reflow my Samsung LH351Ds in my BLF Q8, I had an idea to use with a tofu cylinder container as a big diffuser.

And it fits the Q8 perfectly, and has a much more diffused beam than all of my diffusers. Probably has the best beam of all diffuser I have:

And it snaps over the fins perfectly :smiley:

Now, if it was flashed with Anduril, you could just hit candlelight mode and pop a cork, have a nice romantic evening by Q8light. :wink:

Yeah. It would be so awesome with LH351D 4000k 90CRI and Anduril.

I’m going to reflow them tomorrow when it’s morning, and I’m going to flash Anduril when I get the necessary hardware from China.

Good night.

Built a 532nm stainless steel laser, forward clicky tail switch, 10180 cell.

.

Made a rechargeable 10180 cell for my DQG titanium green laser.

Hmm, that’s not exactly safe is it?

What is its power level?

Nonetheless, great stuff.

I live dangerously :laughing:
Do you mean with the switches? Or the battery? The charger is actually soldered to the cell.
These are only around 1.5mw, fully potted, they do get warm.
For my personal use only.

Oof I was scared. 1.5mW is perfectly fine and legal to use.

In Quebec, that was the case until a few weeks ago when any kind of laser were banned if you are close to an airport.

Yeah I’m scared of the powerful lasers, thought about getting one many times but no.
These wee green fellas are plenty bright and pocketable, can actually see the dot outside during daylight 100m or so and the beam at night is great.

Sometimes when a project fails it opens a door to something that works pretty nicely. That’s what happened here… I was going to build up a 4C Maglite with an XHP-35 but it just really didn’t want to handle the power. I even stepped up to a thicker heavier copper heat sink, in testing that one I burned a black pit in a 35. Ok, so, moving right along… Decided to do something else with the 4C Mag… chopped it this morning. :smiley:

Here is the Black 1C (26500) Maglite next to a 2D for size reference…

Here is the 1C Mag next to my early purchased light, got this way back when I was first getting into lights… JayRob from CPF chopped the Red Maglite, ChicagoX from here finned a head, Elektrolumens made the triple insert, and of course, I tweaked it all somewhat. :smiley:

The new threads and o-ring landing cut into the chopped off 4C tube…

Ah, Maglite! Robust construction throughout, look how thick the tubes are!

Made the copper (Te/Cu Alloy) sink on the lathe with a bit of a column to allow for focus like Mag’s are known for, hand cut the opening of the tube to allow an LED style Mag reflector to fit into the mouth… I like the head to be screwed almost all the way down

I inset the tail spring and bypassed it, while a full sized 26650 cell is fatter than a C and won’t fit I may bore it some day for the higher capacity full sized cell, so it’s already set up to accept it if/when I do that…

A wall shot on low in my Limo Room, we have 5% tint on the windows as my wife used to have bad migraines. I used a Samsung LH351D 5000K 80 CRI on a hand carved 13mm BLF/ Alex Wells DTP copper MCPCB, reflow soldered together. Built a PZL driver with 12 of the 350mA 7135 chips, tail amperage shows 3.35A on a Red Efest 26500 at about 97% charged. (This is a 4 year old cell)

This light really fits my hand nicely, with Bistro as the UI it’s pretty versatile and an automatic win for me, also have an AR coated lens in place. This is just one of those satisfying builds that gives one the feeling if a guy could only have one light, this one would definitely be a contender…. :wink:

WICKED hot today, my thermometer was showing 100º by 9:11AM. Same thermometer shows 116.8º on the porch, a different thermometer with a probe right outside my window shows 108º. We tied a record yesterday with an official 106. Blistering out there, and sultry boiling hot at the lathe. But I love it that way, lol.

How remiss of me! It pulls 3.35A at the tail with the old 26500 not quite holding a full charge. (shouldn’t matter with the regulation chips)

1. 0.6355 lumens
2. 9.35
3. 54.855
4. 170.43
5. 250.47
6. 472.305
7. 986.7

With an 18ga spring bypass in the heavy steel tail spring it makes 1045.35 lumens

For the noobs out there… I’ve built hundreds of lights, and yet when I built the PZL driver last night it was direct shorted. I gradually removed components until the board was bare and still, it was a direct short! So I started over and built a new one with the same components, this time fully successful. Sometimes things just go wrong, it is what it is. Don’t be discouraged, take the time and check it out, start over if/when you have to. All part of the game. :smiley:

PZL is a puzzle of a driver, the component’s placement are listed on the mask under the MCU, you have to leave the MCU til last to see where everything goes! lol It has dual channel capability like our FET+1 drivers, but instead of using an FET it’s got multiple 7135 chips. I stacked 4 extra for the little more power. This driver was done by Alex (Wight here ) in a jovial moment. :wink:

The other side is 6 of the 7135 regulation chips, the one to the right of “BLF” is the moon channel. :wink: (With BLF TDC)

Love the light Dale. Theres a few great names from the past in your build. :+1:

Old Lumens showed me how to stack chips. :wink:

And I have all his kit, so a lot of my Maglight mods are based on stuff from Justin.

There’s been a LOT of people help me out along the way here, don’t ya know?! I think I about drove Comfychair crazy back when we were starting the FET craze. lol

Very nice.

It’s been 29°C here sometimes lately and I can hardly move.

All the buzz these days about price point. Man, I bought that chopped Red 1D Maglight from JayRob making 1000 lumens from a de-domed XM-L! Price point? How about $165! And I LOVED IT! (Ok, I didn’t exactly love spending that much on a flashlight but I loved the light, for sure! It used a 32650 protected cell from NOVAE. Anyone heard of em? All that was available in that size back then…

Edit: Come to think on it, the XM-L was domed, we started de-doming long after that.

ROFLMAO CRX!

It’s 42.2º C at the moment…. 47.2ºC earlier on my front porch thermometer. I’ll take 29, all day every day! (where’s my sweater?…)

I think that would turn me into a puddle :smiley:

Nice work on the Maglite Dale, and those are some good old BLF members you mention! I have been here for 6 years only but the turnover of members has been so fast that it feels much longer.

Time flies… look at you Jos! 12,500 posts!

Says the man with 17500 posts. :person_facepalming:
