@Badpewterz Yu might be able to get away with adding a capacitor in series with the LED on pp3 and pp13. I'm sot sure if added capacitance will mess with anything though, since I'm not sure what those pins are for.

that said, a capacitor will charge up and then discharge , smoothing out the blinks. Depending on how often the activity light blinks, it might smooth things out a bit.
