I need evidence. I've been through TSA lots of times with mine and taking it on transcontinental flights. No one's ever cared. Last year I flew to Def Con with a Mesthtastic radio and a Raspberry Pi server strapped to my backpack, complete with cabling, and no one batted an eye.
There's no regulation against carrying one around with you, including on flights.
Likewise, I've flown more in the last year than in the decade prior and every single leg my Flipper has been in the side pocket of my backpack. Never once has it received even a second look from the TSA, including also DEF CON.
