@markeats sorry to bother again and maybe this should be in the shield thread but, i amanged to get grid + passersby running again as soon as i was able to connect to wifi again.
But now i realize that with the new norns firmware, there is a wierd power / noise issue with passersby wich i suppose is based on its high cpu demand and happens also with the awake port.
When i drive from a chunky 3 ampere powerbank passersby makes a ring mod kind of distortion noise on note play every few seconds. This deosnt happen when wallplugged.
The noise fades in and out and really resembles a ring mod effect quite exactly but ofc is problematic.
Afaik this didnt happen with the older version of norns / passersby.
Any idea what i could do to use my powebank but fix the issue?
