Revision as of 02:25, 27 February 2013

This is Yoo-Yoo (Yo-Yo) Yeh's 250B page

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: 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.

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

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:

but first, I went somewhat slinky crazy.



Week 4-5: Egg weeks.


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:

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 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 are two videos: PiezoFlower Garden Boom 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:
