Like you, I find the more I talk to people about what I’m doing (without going beyond their level of interest), the less they’re spooked. Especially when I’m prepared to talk about how I’ve thought seriously about safety.
Whereas the more people just happen to see stuff that’s unfamiliar to them, the more they imagine movie tropes to explain it. Sneakiness and a “you wouldn’t get it” attitude just code you as obnoxious, and color their assumptions accordingly…
You know, after pondering this, I think we're making progress. For example, I haven't heard the bare PCB and/or wires = bomb trope in years! Know your audience, as you imply. If asked what you like to do for fun or hobbies, selectivity in the response and assessing the situation helps!
