Simple Respiration & "Monkey-Mind" Sensor

(under construction -- check back soon for updates and additions)

With the advice of the goddess/oracle Margot Jacobs, I successfully made a respiration sensor with a Basic Stamp and a pressure sensor (sometimes called a Force Sensitive Resistor [FSR]). I have used this a number of times in performance:

- Farewell Rituals (2003)
- Sitting.Breathing.No.1 (2003)
- Sitting.Breathing.Beating.[Not]Thinking (2004)

Note that this device is not respiration specific!! The following code, schematics and whatever else can be used and modified for any situation where a button or pressure sensitive controller is needed!

Before you go any further, see the rest of my Resources sections if you haven't used Basic Stamps or PICs before

MidiBreath&Brain002.1.bs2 (textfile for MacBS2)
MidiBreath&Brain002.1.bs2.pdf (as a pdf)

I based this code on a handy MIDI Out program I found online, and also used Matt Rogalsky's wonderful website to fine tune it.
I used this code with the free Mac OSX program MacBS2, but assume that it will work with any PBasic-related compiler...
