555 Timer Synth Duck Jammer Vol. 1

Vol 1. of a series of crude synthesizers built into Rubber Ducks, hence forth known as "Duck Jammers".
This circuit is a typical dual 555 timer which has been covered exhaustively online, so I didn't bother to get into it very deeply in the video. The song at the end features 5 different parts that were made using this synth, some obvious, a few less obvious, can you guess which?

I love the drawings of the duck and 555 timer. Very Home Movies like.

Haha! Yeah! Riding that line between just crappy enough to be charming, and just plain awful =P. Thank you!

Thank you so much! I'm glad it's not something that is boring as fuck to people who aren't necessarily into electronics!
