FW1AA RGB AUX
lemmy.world

Hello, first post here :D

A few month ago I modded a FW1AA with boost-buck driver for NiMH/li-ion and with RGB LEDs.
I used a TIR lens for the aux led to shine through, unfortunately it had artefacts in the spill that ended up a bit too distracting so I went back to the original reflector and used a thin flex PCB under the reflector with tiny LEDs that fit in the opening. I’m very satisfied with the result, plus the beam with the 519A+ SMO reflector is surprisingly good.

    Great work man! I knew you had a 5050 flex aux PCB, but didn’t realize you also had a 3535. Is that on oshpark?

        Awesome! Do you think if I can fit these RGB leds under an original FW1A reflector with the smaller opening (not the crappy FW1A Pro reflector)? If I can eventually find one that is.

          What’s the diameter of the opening ?

          Edit :

          If I can eventually find one that is.

          Oh you don’t have one, measuring from a picture I get 5.9mm, if that’s right then it will be very close.

          I can try making a version with the LEDs closer to the 3535 cutout.

            Yea I don’t own one yet, but it should be around 5.6mm to 5.7mm.

            I can try making a version with the LEDs closer to the 3535 cutout

            That would be great if you could, thanks.

                Excellent! Thank you so much.

                So this should work for the original FW1A?? That is exactly what I need!

                  I guess it should. Unless the corners of the flex boards overlap with the MCPCB solder pads, since it was designed for a smaller MCPCB.

    Glad to see you here!

    And that flashlight is AWESOME!!! 😎

    I am looking into sourcing some of these RGB leds to try, and discovered that there is an even smaller model available.

    B36S3RGB is 0.69 x 0.69mm. These are the ones you are using.

    While

    B36L3RGB is 0.65 x 0.65mm. Have you thought about using these?

    I have not studied the datasheets in detail but from a quick glance, apart from the size, they seem to be identical otherwise.

      I don’t remember exactly but I probably chose the 0.69mm ones because they cost half as much. The 0.04mm difference being pretty negligible. I also have the 0.9mm ones that I use when the classic 0606 are just a bit too big, they are easier to handle.
