The LED Ampli-Tie is a DIY electronic necktie that doubles as a working VU meter (volume unit meter)—it’s the perfect accessory for audiophiles and Daft Punk superfans. A microphone hidden near the tie knot monitors volume while 16 LEDs down the length of the tie serve as the visual readout. The tie was created by Becky Stern of Adafruit Industries. If you’d like to make your own, check out Stern’s how-to video and online tutorial.
