today Sasha let me borrow the small Radio Shack amplifier+speaker and i tried to get my roommates to listen to my heartbeat through a piezoelectric disk. not as good as a stethoscope, but fun. :)
ideas doodles:
Going off the "rain chime", perhaps it could also be possible to have a "slinky piano"? :)
And if you have never been in the stairwell of Packard, I think the stairwell between floors 1 & 2, and 2 & 3, have great potential. Lots of echoes there, and the stairs are made of metal!
Week 3
Going off the "slinky piano" idea, here was iteration 1: slinky piano attempt #1
Then, I think it was Eoin who mentioned the words "steel drum" and there happened to be one upstairs, so here we have a lovely video:
metal slinkies + steel drum = awesome underwater kind of sound
This is the week when I carried a small slinky around with me 24/7, to show anyone who would listen. :) And blew out a RadioShack amplifier.
Later I switched to a piezo disk, audio amplifier, and headphones. Still have plans to pop a balloon in Packard stairwell one of these days. Stomped down the metal stairs in tap-dancing boots the other day, that was LOUD.
more ideas doodles - John had an idea to pop balloons - well that is difficult - but bubbles pop! And they are easy to regenerate. so:
(doodle here)
then I went somewhat slinky crazy.
Week 4-5
Egg week.
Week 6
Acquired 30 additional slinkies/magic springs from Anya. Bought some more of my own. Ordered some online. Of varying sizes and shapes.
Actually building things - Sasha said I could cut up the sheet metal in the lab, and handed me a hot glue gun. I had previously been thinking of plastic or paper leaves/petals. Also lent me a guitar effects pedal. So we'll see what that sounds like!
Metal petals are actually really awesome!
Week 7
Additional variations, more soldering of audio jacks, piezo discs hooked together in parallel.
Vases from Paxton Gate coming in tomorrow. Bought a terrarium from Costplus World Market in the meanwhile, and filling it up and blowing bubbles at it! With or without the guitar effects, both have very interesting sounds.
Here's a video: Piezo-Flower Booms
Jonathan says the low pitch of the flower petals may be related to quarter wavelengths. Maybe I can make a smaller flower and test this out! In any case, here's the latest iteration:
