Thread: Canīt get Neopixel Blade to work

    Default Canīt get Neopixel Blade to work

    Good evening Gentlemen,

    I have a question which might not be simple to might hope though
    I recently aquired a saberforge build kit with a golden harvest v3 soundboard,
    Neopixel connector, battery etc. and a Neopixel lightsaber blade.

    Since this is my first build and I have absolutely no soldering experience the manual task was challenge enough.
    But I managed....Now the problem.

    The board seems to work fine, I can hear sound, switch lightsaber fonts and so on, but I cant ignite the blade. I do get
    a few pixels to flash for a second but thatīs it (Amperage of the battery too low?...though I think it would be weird...why sell a kit, that wont work as intended?). What is the usual method for testing if the LED Strips are working and are soldered correctly in the pre-assembled blade?

    Thanks in advance

    Welcome to the forums.

    Offhand I’d say the battery amperage was insufficient. You need a 15A battery to run a setup like that.

    In case you weren’t aware, these forums are attached to a site (The Custom Saber Shop). I removed your links as they go against the forums guidelines.
    Also, just so you’re aware, that company you mentioned isn’t highly thought of in the community.
    All n00bs READ these first (PLEASE)!!!:

    "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..."

    I agree with FJK that battery is definitely a good spot to start. I'm not super knowledgeable with golden harvest. I know that with plecter labs, you have to define the blade in the soundboard settings. Make sure it isn't something similar with that board

    Thank you for your Input...this is very much appreciated.

    In the GHv3 Settings you do have a LED Strip setting where you can define the number of Pixels you are using. I played with these settings but to no effect.
    I will get an appropriat battery and try again.
