I need to get in touch with someone in the field that knows their stuff for a simple, yet useful invention. I would need to get a prototype made up and then go from there.
It will have to be very lightweight (if possible, less than a few grams… but for a prototype, it could be a little more until I can source better parts) and compact and either use a very bright LED or a loud high pitched speaker that can be controlled remotely via RF (and programmable for different frequencies).
I haven’t done anything like this since Highschool shop class, so I figured I’d see if anyone here is interested in it first. I did a quick search online and it turns out that nobody seems to have thought of this yet, which is good (or at least, no patents are held)
