Thread: Would this even be possible?

    Default Would this even be possible?

    So I'm building a saber for my roommate because he's been ogling mine for a while now. He doesn't want sound and ordered a tri cree white white white LED. Is it possible to run that off a 3.7v 18650 battery pack? Pretty sure he's gonna need a buckpuck in addition to the momentary to latching converter since he wants the 12mm av white ring switch. I'm still super new to this all and figured reaching out before I dig myself a huge hole or break something would be the way to go.

    Current parts list
    Tri Cree White
    lens
    holder
    all hilt body parts
    White ring 12mm AV
    3.7v 18650 3400mah

    Needed
    Buckpuck?
    Momentary to latching converter
    Resistors
    A clue

    You would be better off skipping the Buckpuck, and just using resistors.

    "Yeah, yeah, I've heard it all before... you want blindingly bright, super loud, running 1138 blinkies off of the cheapest sound card you can find AND you want all of it to run on a battery the size of a dime, and run for a very, VERY long time. That one cracks me up every time..."

    Sweet, could I get away with using 3 .5ohm 3w resistors? and A dynaohm for the switch?

    Yup, the 0.5 would be right but they are slightly overdriving, which isn't that bad, but getting a 0.6 ohm would be my suggestion...
