What did you mod today?

That may be why I couldn’t open mine. :person_facepalming:

Finished the mod, just swapped led with a 3500K LH351D, glued the PCB back in place with AAA and pressed the alu ring in again. The beam is still far from perfect, not in flood, not in spot. But the tint makes this now a very pleasant headlamp for someone who is not a snob, also because of the charging port. I have some protected NCR18650B cells somewhere, with these it is a nice gift for a camper.

What i wanted to mod today
changing the Led will be a feat without destroying everything on this bad Nitecore tube pcb

Go for it :smiling_imp:

What is bad about the pcb?

The anod is welded together with a small resistor and lot of blow
Previous image was enlarger,working space is small for the point of my 60W Iron solder
otherwise I cut Led :)?

Afer the use I found slight unscrewed the pill on my s2+, could have as a consequence bad pressure of the mcpcb on shelf surface.I added another retainer ring(also right washers should be fine)take from a junk light that now lock the pill.It also secured by the pressure of battery tube.

If you like this hobby enough, get a hot air station. Getting components onto and off boards is a breeze with it.
Or, a smaller soldering tip from Aliexpress.

Either way, this sounds like a cool mod.

Hey Sari33, I’d recommend taking the extra retaining ring out of the S2+ head. Normally the head screws onto the body (battery tube) until they meet. There should not be a gap between the head and the body. The body does not need to touch the driver retainer ring.

Where there should be a gap is at the tail. That’s where the body touches the switch retaining ring or housing and allows the flashlight to be locked out by slightly turning the tail.

Or maybe I’m not understanding your issue.

No,sorry maybe the barrier languages.
First I tightened the pill then I put the retaining ring, this because I founded the pill a little unscrewed last time and now Is secure pressed.

IFAIK there has bever been a retaining ring on the head side of a Convoy S2+…
In the head-combo you’ll find in that order:

O-ring (rather thin green GITD)
glass lens
reflector
centering ring
pill

This should be enough to press the pill in with the body.
Maybe you should consider using a thicker O-ring.

As already stated, there is a retaining ring IN the pill, that does NOT touch the body.

I turned the diffuser into anti-glaring hat for a bicycle flashlight, which is to prevent dazzling people from the opposite direction. It didn’t look very nice, but it works.

All of my S2+s have a retaining ring to secure the driver. I prefer not to have them soldered in.

Whether or not a retaining ring is used has a lot to do with the type of driver. Some, with a ring of 7135 regulators need the retaining ring to be filed out on the inside to clear the 7135’s or are soldered in place instead of modding the retainer ring.

Finally got the boards in to convert my Amutorch E3 to Anduril2 with RGB Aux LEDs. It was a very tedious mod, but after a couple setbacks I think it turned out really well. I made a custom attiny1616-based FET+1 driver and used Loneoceans’s RGB Aux board for the FW3x series.

Nice work Gchart.

Nice gChart, more next level modding.

Probably the shortest 21700 cell light (@95mm) with Anduril, a pocket rocket.

I think I’ll have dig up my E3 and give it another look.

great work gchart, nicely done

Replaced Thrunite Cat6 V2 reflector with TIR Optic.

The inspiration for this mod was the result of seeing user reviews of the Manker MK37 and U22III lights with large TIR optics. I was able to find a similar looking optic on AE.

The Thrunite Cat6 V2 reflector cavity/dimensions (~ 52x29 mm) worked well for this optic, which measures 47mm dia x 29mm ht. The hardest part of this mod (or any mod where reflector or optics are involved) was getting it properly centered and focused.

Optic (slightly lowered to help focus) with DIY spacer/centering ring.

FWIW in the screen captures (see below) from BLF member andreas0401’s video review of the Manker U22 III one can see the result of this optic vs a traditional reflector, in that case using the SBT90.2 emitter. I get analogous results with the Cat6 and XHP35.

White-wall shot showing traditional reflector hotspot from U21 vs the new optic in Cat6

Screen capture from andreas0401 video illustrating this optic in the field, broader hotspot w/less defined spill (NOT the Cat6 in photos)

Unlike most mods the result was not more OTF light, just less as spill.

I want to love this light, and even more so with this mod, but I just know it will never get carried over my KR4 or SC62w.

May I ask, what were the setbacks?
