Is it bad that they try cheaper optics? $1.5 per lens is a lot and Carclo is not bad but not special either. It may be possible to match the quality while cutting some cost but there’s a risk of the manufacturer settling on something worse.
It would be better to do this move earlier as compatibility is a major constraint. Then maybe it would be possible to even improve the lens…
What’s the better alternative? $1.50 doesn’t seem like much to me, considering the comparative cost of everything else.

Yep reduced optic to 23mm diameter, you also have to champher or reduce the hieght of the mid section (light engine) to fit/clear the bottom of the optic…so it seats fully into the board.
I see, thanks! Have you also replaced the optic in S43? If so, I’m very curious to know what you sourced and what mods were necessary. Grad

Nope never jumped on the S43 band-wagon. S41’s I turned into Triples, the S41 optic/board was tearing up the emitters.

Hello helooooo. I got my fw3a dismantled as I'm trying to do a firmware flash to toykeepers firmware for a 219b build. I'm running into an issue understanding the ping layout on the usbasp up to the SOIC clamp. I suspect it's this reason why I keep getting an error "target doesnt answer. 1" How do I repin the SOIC so it matches what's in the usbasp and for a tiny85 chip?

You could get some dupont connectors and put them between the programmer and the SOIC ribbon cable. this would allow you to reconfigure however you need. You may even be able to replace the ribbon on the SOIC with the dupont connectors.

Alternatively, if you have some solid core wire of the right diameter, you could use that instead of purchasing the dupont connectors.

If you can get the ribbon off the SOIC without breaking it, you could reattach the ribbon in the correct configuration (maybe solder it?).

Sorry, I accidentally replied to the wrong person. Look at my response above for some ideas on how to change the pinout on the SOIC.

As for the pinout, check this post out: BLF Link

I have used it as reference for flashing all my lights when I need a refresher (attiny13 is the same pinout as the attiny85)

Awesome I do have those Dupont con doctors. I bought them when I got the usbasp not knowing why I needed them but now I see where they come in handy Smile

Modded with high CRI LH351Ds

Probably took too thick wires for the aux LED on prtototype
on first assebly I had the driver twisted to align to the heads cutout and ripped the pad where the optical nerve was off
so disassemble again, looks messy with the heat paste all around

Prototype, got a small bug, but can be used without the LVP chip, the bridge pads were designed on it so no big deal
but the fab let me down not cutting out the 20mm boards from the panel, so I got ordered new ones

Also made a quick thermal test, that thing gets hot fast

Will the aux board work with the stock mcpcb or only the noctogun?

Looks great, Lexel! I assume the aux LEDs would always be on?

if you flash driver and remove the optical nerve resistor you can solder there the Aux supply
then flash a firmware variant that supports the Aux LED option

Removed 2 7135’s from my FW3A. It still thermal throttles with a full battery. But with a more empty cell it can sustain max regulated output for a long time (probably indefinitely). I did a calculation to determine how much the efficiency actually went up, and it wasn’t much… But still technically more efficient than the pwm equivalent with 8 drivers.

I was worried that the mode spacing (or ramp rate) would be non linear between the 1×7135 and 6×7135 sections, but it’s still very good.

25mm… I think there may be a few diffusers from other manufacturers that could fit. One that comes to mind is by Nitecore, with a 25.4 mm diameter. One could line the collar of the diffuser with some aluminum tape to get a snug fit.

This is what I ordered. I will see how close it fits, but the aluminum tape is a great idea!

Experiment-ing….little 0603 led’s are a PITA! Angry Touchy little critters too…poofed a few! Facepalm Actually had the little 0603’s fitted in the trit holes…..

More Purple than Blue, the Green trits are about twice as Green, but the camera dislikes UV…waiting on the micro band-pass len’s now….might try the band-pass film….we’ll see…. Thumbs Up

AFAIK There is no “optic nerve resistor”. Only the pair of resistors for the FET (pull down and gate) and the input filter “R4”.

If you want a great diffuser that is snug fitting & will stay on get THESE , they are great!! They fit perfectly, stay on, and diffuse great.

They fit as they come… no adjustment or tape needs to be used. They fit perfectly.

KB posted about them… I have quoted it below. I have the same colors as in the picture. I love em’….. Smile
