We've seen lots of nerdy underclothes before — but this Star Wars-themed "theremin bra" might be the ultimate. It makes vaguely R2D2-inspired noises whenever anybody comes close.
According to the maker, Instructables user caitlinsdad:
Don't touch that dial. No tweaking the knobs. Just wave your hands in front of the two sensitive sensors embedded in this bespoke piece of wearable tech.
The garment has an embedded Adafruit Flora wearable microprocessor to generate R2-D2 theremin like sounds.
Below is a video of the bra in operation. And if you want to find out how to make your very own "theremin bra," check out the Instructables page.
