Physical Computation Final – Progress

December 2, 2009 BY Aston

So I await my dozen Piezo sensors that, I assume, are stuck somewhere in the postal system as they have not reached me yet.

I mention this for two reasons: 1. I have not been able to progress beyond a two drum setup 2. I am getting weird and different readings from both piezos. One seems to be ultra sensitive while the other is a bit harder to read, like a married couple. I am, so far, attributing this quirk to the horrible, horrible soldering job I did with the piezos. I only learned how to properly solder them afterward. Which makes this new shipment of piezos all the more important.

Take a look at this atrocity!

Here is my setup from afar. Two buckets (so far) with piezos doubletaped inside. I made small canals in the lip of the bucket for the wires.

These are the guts of the bucket.

The breadboard is set up for the two buckets with readings coming in from the piezo, tamed by a 1M ohm resistor and protected with a 5.1V Zener diode, since the piezos generate electricity (and shoot it back into the arduino).

More to come!
