Honestly, twisting the signal wires made a night and day difference for me too. Also started paying more attention to grounding, like making sure all the grounds hit the same point instead of daisy chaining them everywhere. Huge noise drop after that.

Oh man, that coffee shop guy is missing the whole point of bullet journaling. I get what he's saying on the surface, but for me it's WAY more than just a fancy to-do list. I track my sleep, my water intake, how much I spend on takeout - stuff that really matters for keeping my life together. The drawing part is just bonus, it makes me actually WANT to look at my journal every day. Without that habit tracking, I'd probably forget to pay a bill or realize I haven't exercised in two weeks. So yeah, it's a to-do list with some extras that make a huge difference.

Happened to me too, starter got so active it pushed the lid off and dripped down the cabinet. Just scraped it back and kept going, turned out fine.
