Hi everyone. I am building my first saber and I was almost done when it stopped working! I am hoping I can get some help from you all.
My setup: I am running a CFX board with neopixel and a crystal chamber. I am using a 18650 15A Keeeppower battery.
My problem: My board is blinking red very quickly when I remove the kill key similar to when it did when it would scan the SD except now it doesn't stop. It continues to blink and there is no sound or LED from neopixel or crystal chamber. This really has me stumped. The board was working perfectly while I initially did the soldering and even though out my testing. I spent a day editing the audio files and visual effects and everything worked fine up until the point where I started to shift the board and battery in the hilt.
What I have attempted to do to solve the problem:
-updated the board firmware (again)
-reverted to using the updated/default sound files from main website (10.005C)
-reformating SD card using normal windows and SD Card Formatter
The only things I did prior the board not functioning anymore are:
-Re-format the SD card and re-upload my files on that wiped card. (Using FAT32)
-Push the board, battery, etc. into the hilt. Maybe this created a short or something?
It is worth noting that one of the RGB wires from my crystal chamber LED got disconnected when I was moving it all into the hilt so I had to pull it all out and re-solder that wire. Unfortunately, this did not fix the problem.
I debugged using RICE and I was getting an error saying that a valid SD card needed to be inserted. Given that I reformatted my drive, I thought that I must have re-formatted it incorrectly but I have reformatted dozens of times using various programs and no luck. Plus, I was able to successfully update the board firmware which successfully read the .dat file off of the card. I only updated the firmware again because I thought that perhaps some short wiped the firmware when I was putting the electronics in the hilt.
At this point, I am starting to believe either a short was created when I pushed it in the hilt and now maybe the board is fried? I really don't know... Let me know if you guys need any other information from me. I don't think it is my sound files, config, or anything like that because it was working before and all I did was copy and paste those files back into the re-formated SD card. Could a short cause this problem? I just really hope the board isn't fried. I did use a multimeter on some of the board parts and I was getting mV where I was expecting 9-10 volts. :/
