Haha, I totally get you! Replacing social media time with those kinds of 'side quests' is honestly the best trade-off. Who needs to 'just relax' when you can have your brain fully engaged in solving random technical mysteries or growing stuff?
​Man, finding out it was just an AC power issue after experimenting with 9 C-cell batteries is a classic! There’s nothing more satisfying than that 'Aha!' moment when the tracking lines finally clean up on an old TV. Good call on ordering the new power supply.
​And about the mushrooms, that sounds awesome! Growing them in cardboard and coffee grounds is a top-tier project. Take your time, I'll definitely be waiting for that update in three weeks to see how they colonize those grow bags in the basement.
​Good luck with both projects, man! Keep staying busy!
