Behold … the Rusty Growler!

From the MAKE: Flickr pool

Tremble at the feet of Rusty Sheriff’s mighty “555 astable tone generator with tuned keys” – sporting a big ol’ 8″ woofer and a laser-cut case. No performance samples to be found but the name/design alone is satisfying enough – Rusty Growler

Please, share pics of your awesome works in the Make: Flickr pool – we love this stuff!
