Oooh, I realize I can now build wearable antennas using this sewing machine. I just need to buy some conductive thread and figure out what kind of antenna design to sew into something... Radio hat? T-shirt shortwave antenna? Wearable APRS tracker?

in reply to AI6YR Ben • • •It got me going down the line of trying to use a strip of RGB LEDs to do a persistence of vision thing with an Arduino and a slightly larger kite. I never got the Arduino code to work well enough to fly it, but it was a good learning experience.
Now my kid has me doing a project with electroluminescent wire (from Adafruit), and there will be some leftovers... I might have fun doing a little wearable project out of that.

This bicubic reflector is too ugly.

in reply to AI6YR Ben • • •@n8dmt @MisterMadge Although alignment of an exact right angle might be hard, I suspect that just putting some kind of grid into a safety vest would make it extremely radar reflective since humans are not flat. The only question I have is how dense of a grid you'd need to show up on the radar systems. Better to put a bunch of grid patches on the vest in various spots, or are you just good putting a strip of wires across the back, etc.

Good chance you'll come up with something that'll reliably set off those !@# detectors as you go in and out of shops though.
