PiezoFlower Garden

Week 8: PiezoFlower Garden, v.1 and v.2

This is a productive week! Today installed happy flower and spiky beautiful sound flower into their vases, with the help of some paperclips from Jonathan and lots of hot glue. Hot glue may rise up to rank in usefulness with zipties. :)

Eoin found a song using the slinky on top of happy flower's vase. Thanks to Samanthi for the leaves. They have proven very useful.

Here's some closeups of the first two installed flowers. Videos to come. Happy flower leaf.jpg Ringing flower leaf.jpg

(Edit: hanging vases have arrived, and they are quite beautiful!) Also arrived: the small piezofilms from Digikey, which may fit better inside the hanging vases.

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.

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:

Week 6-7: Looking for those hidden sounds

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! And the smiley face sticker is a MUST.


Week 4-5: Egg reverberation, Mini-Squids.

After I shorted my $17 Radio Shack amplifier, Travis mentioned that one could buy cheap headphone amplifiers online. Ordered a Fiio headphone amp for $4, and it is proving exceedingly useful for testing.

Sasha mentioned Helmholtz resonators in class. See previous doodle... I wanted to fan eggshells and make music come from holes in a wall. Still a possibility. Just need some amplification: Egg acoustics.jpg

That's a condenser microphone inside a hollow eggshell (yes I washed it out first). It sounds really nice, actually. Something like a seashell. That's what it sounds like to be within an egg.  :) I'll have to make a recording.

This week I switched from carrying around a slinky to carrying around a slinky, a piezo disk, audio amplifier, and headphones.

Week 3: Slinky Pianos, Giant Squids

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.

Video: 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 the lovely

Video: Steel Drum - Steel Slinkies 1

metal slinkies + steel drum = awesome underwater kind of sound

Both Eoin and my roommate Tamara says it looks like a giant squid. Tamara likes squids. :)

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)

but first, I went somewhat slinky crazy. Starting collection of slinkies.. now.

Week 2: Brainstorming

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. :)

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!
