Thread: Nano Biscotte issue

  1. #1

    Default Nano Biscotte issue

    I'm hoping it's just my screw up and not the board (so I can hopefully fix it myself). I've been running into all kinds of snags building my latest saber (the first problem, I'll admit, was my own error). This time, I'm confused because I've never seen this before. When the saber is all plugged together as it should be, it works perfectly fine with the killkey in; no sound, no light, nothing, perfect. When I pull out the kill key, the main led (green in the picture) powers on even when there's no sound going. And then when I hit the switch, the sound plays and functions as normal, but I don't get any blade flicker or shimmer-on-clash.

    What the heck is going on here? Here are a few pictures, as well as a short video to show what's going on. Is the board screwed up, or did I damage it somewhere, or is my config file screwed up (PLEEEASE be this one!)? What gives? Any help would be appreciated because I have no idea what the hell I'm doing.

    The board is powered by a 3.7v 2600mAh li-ion, the main led is a Seoul P4 (green). Here's the config file as it stands:

    //Nano Biscotte AMBER MYSTIQUE
    vol=4
    drive=900
    offd=200
    deep=15000
    resume=0
    lc=420
    hs=200
    ls=50
    i=55
    shmrd=210
    shmrp=6
    shmrr=13
    swing=200
    clash=150
    qon=0
    qoff=0
    flks=5
    flkd=20

    Could you please post a more "in focus" close up of the board as well as a close up of the back of the recharge port?

    I don't think it's the recharge port. The problem persists even with the battery connected without the recharge port. The following are the best pictures I can manage (I only have a camera on my phone so my capabilities are limited).

    You've got too much solder on the joints and bridged two negative contacts. Each pad should be separate.

    There should also be heat shrink on the charge port, and if you can don't strip as much housing from the cable. Just enough so you can attach the wire to the pad, don't want any over hanging that can short out.

    So clearing them up and making sure they're not connected should fix the problem?

    Yup, like Jordandau said. You have bridged your LED- to your battery-. Since you are getting your LED+ off the main battery+ anyways, you are effectively powering the LED directly whenever you hook up the battery. Clean it up and you should be fine.

    That's a gigantic relief. Once I do that, I'll post the results. Thanks for the input, guys.

    Yes, the others are correct, that's what I thought I saw, but I wanted to make sure. You have those 2 bridged.

    Yup! I just cleaned it up and reconnected everything and it all works as it's supposed to. Lesson learned: take your time and make sure everything is clean. Thanks guys! I really appreciate it.

    Looking at your main picture you dont seem to have any resistors for your LED's. I only ask because im going for a similar set up and I thought I'd fry my LED's if I didn't put them in.
