Thread: Neopixels no longer work...

    It is a bit unclear which batteries work best with neopixel without doing some research. It would be cool if the correct ones were cross listed in the store under the neopixel section, like the resistors and the screws are.

    Thanks again,

    Yes, it is in the config.txt file. For me, it was just above the ledstrip parameter. One of the symptoms was, if I turned on the saber but before hitting the ignition switch, I hit the aux switch, the blade would light up in Power Level Indicator mode. So I new the neopixels worked, but the ignition switch would not turn the blade on. My version is "CrystalFocusX-v10.004D".

    Hope this helps,

    Bob

    You have to know what version of firmware you have on your card before you just go randomly adding parameters.

    Bob,

    Just another quick look showed that line did exist on an older backup of my config.txt file. I have added it and hope to test this weekend, even with my underpowered battery to see if I get anything...

    Thanks again,
    Jon

    Bob,

    Just a quick update.. I hooked it up to the current battery, with the line back in the file and still no lights. I even let the battery charge for a few hours. New bigger 26650 battery will be here Monday and after letting it charge I will test and let you know.

    Hey Jon

    Did you get a chance to hook that new battery up? Curious to see how it worked for you.

    Ok, so battery delivered... Hooked up to cfx and tested, still no lights... I am beginning to wonder if I fried the strips... I get voltage going to the Pixel strips, tested at 3.56V. My charger wont be here until Monday, where I will charge the battery and test 1 more time when I am sure the output current will be sufficient to run everything. The battery I am using is an Obtronic 26650 battery with the below specs...

    Cell Capacity: 5500mAhCell Type: 26650Dimensions: 26.5 mm x 70 mm (+/- 0.9mm)Full charge: 4.2VRecommended charging current: 1A - 3.5A CC/CV (Battery can be charged with current lower than 1A, but charging time will take much longer)Nominal voltage: 3.7VCut-off: 2.5VMax. Constant Current Discharge 15A*

    Did you check to make sure the battery is fully charged first?
