Good Afternoon!
I am nearing completion of a double-bladed build and am having some sound troubles...
Each LED module uses 2 Deep Red dice, left side on L1 and the right side on L2. Each module has one White FoC, both wired to L3. Initial testing went well. I wired up the first module and tested everything with great results. Then I added the second module, and now there is mad static coming from the speaker. The issue is gradual too, which is odd. At first everything sounds fine, but the longer the saber is on the worse the sound gets.
1) Yes, it is the stock SD card, though I reformatted (as usual) when I changed some of the settings (just the driver settings).
2) Am I pushing the board too hard, trying to run six dice at once?
3) The right side positive leg is wired to the recharge port positive terminal (an attempt to save space). I mention it because Erv asked about this in a similar thread awhile back. I know the NBv4 is supposed to help with voltage ripple, but would having the board pos, batt pos, and led pos wired to the same spot defeat that feature of the board?
Thanks!
