Yeah man I did the exact same thing last year. Screen size is definitely the weak spot when you're trying to do fine detail stuff.

$30 cash is a solid deal honestly. I once traded a whole box of Asimov paperbacks at Wee Book Inn and they only gave me $12 in store credit, I was kinda ticked off about it for like a week.

Man oh man, I feel that in my bones. I did the exact same dance with a framing square for years, just eyeballing and hoping my porch roof wouldn't leak. It's wild how a little piece of paper with some numbers on it just makes everything click, isn't it? Jimmy did you a solid. I still remember the first time I used a book for hip and valley cuts, felt like I finally joined a secret club nobody told me about. Don't beat yourself up over the lost time though, that's just how it goes with this stuff. You learn from the struggle, even if the struggle was completely avoidable.

My buddy had this same issue but with a completely different setup. He put a wireless glass break in a dentist's office and it kept going off every time the autoclave cycle finished. Took him forever to figure out since he assumed it was just a sensitivity problem with the sensor itself and kept tweaking the adjustment. Finally swapped it to a hardwired unit and the false alarms stopped completely. The RF from that sterilizer was just constantly hitting that frequency.

Honestly 230,000 pennies is wild, @ryan719 probably gets the real headache of finding those things in cupholders for months.
