=Pi skin conductivity=
===wiki pages===
Aims:
* [[The_Ultimate_RPi_Installation_Guide]]
* 3 pairs of GPIO pins are used as to capture skin conductivity
* [[Pi skin conductivity]]
* python reads GIOP (should run as a deamon)
* OSC sends messages from py to pd
 
 
Pis have no ADC, therefore the simple way to read a Pot's value is via a step response technique as explained in http://razzpisampler.oreilly.com/ch08.html

I am using 500K variable resistor(pot) instead.

* ???
[[File:GPIO-touch.jpg|right]]


In order to use touch pressure: I kept the circuit only replacing the variable resistor
==RPi3 setup==
with 2 metal pins.
===Base System===
Follow the guide [[The Ultimate RPi Installation Guide]]!


The result is very interesting.
You need at least to have a base system and hotspot working for now, more specific details soon.
* because the circuit is interrupted while no one is touching, the stream or reading is interrupted
* values can go from:
** Max: 3  (very strong,wet contact) (0 if there is a metal connection )
** Min: 273337

=== Floppy disk system ===
==== Testing if everything works fine ====
* plug floppy disk drive
* check it is recognised by the system, checking for instance with dmesg, example output:

RPi3 setup

Base System

Follow the guide The Ultimate RPi Installation Guide!

You need at least to have a base system and hotspot working for now, more specific details soon.

Floppy disk system

Testing if everything works fine

  • plug floppy disk drive
  • check it is recognised by the system, checking for instance with dmesg, example output:
[ 1505.185614] usb 1-1.5: USB disconnect, device number 5
[ 1513.164425] usb 1-1.5: new full-speed USB device number 6 using dwc_otg

[ 1514.506805] sd 0:0:0:0: Attached scsi generic sg0 type 0
[ 1514.885427] sd 0:0:0:0: [sda] Attached SCSI removable disk
  • Insert floppy, and check that a block device is created (still checking with dmesg):
[ 1592.965421] sd 0:0:0:0: [sda] 2880 512-byte logical blocks: (1.47 MB/1.41 MiB)
[ 1593.989421]  sda:
  • make a temporary directory to mount the floppy to
cd
mkdir floppy
mount /dev/sda floppy
  • check that you see the content of the floppy in the floppy directory:
ls floppy

Format floppies if needed

  • Insert floppy
  • Check which block device it is using (/dev/sda in this example) with dmes
  • Force format the whole block as vfat giving it a label,
mkfs.vfat /dev/sda -I -n "SECRETFLOPPY"

Useful Commands

speaker-test -D hw:0,0 -f cd
