A hundred and fifty bucks for a phone camera? That's a serious chunk of change for a single tool. I would have just kept poking at that board with my multimeter forever.

Wait, was this at a public library or a school library? That's a big difference. A public library shouldn't be enforcing a school's filter rules on a personal device. If it was a school library, they're probably just following their own internet policy for students.

So which brand was that inflatable lantern?
