Awesome Horns

If you want a loud noisemaker, you could always buy one of those compressed air horns, but if you prefer something that you can reuse over and over, check out HABU’s build – which uses a modded cordless power drill and a small compressor pump to blow air through a pair of horns.

The yellow machine you’re looking at is “Le Mécanophone,” otherwise known as a 1935 Citroën truck, equipped with 42 different car horns. But this thing doesn’t just beep, it’s basically a calliope on wheels. We want one of these just so we can honk at traffic all day long.
