software this requires:

   gpasm (gputils) - GNU PIC Microcontroller GP Tools
   g++ - GNU G++ Compiler
   picp - PICStart Programmer
   gmake - GNU Make
   PICSTART Plus Programmer hardware

hardware you NEED:

   1 PIC12F675 8-bit microcontroller
   1 1uF capacitor (c1)
   1 tiny speaker
   approximately 2-5VDC power supply

hardware that is optional for the zobel network

   1 0.1uF capacitor (c2)
   1 10 ohm resistor (r1)

optional hardware for the 'im working' indicator

   1 LED (d1)
   1 1000 ohm resistor (r2)

the schematic is as follows:

              +--+
    +Vss <----|18|--| gnd
              |27|
        c1 +  |36|  d1    r2
      +--|(---|45|--|/>--/\/\/\---| gnd
      |       +--+
      |   c2   
      +--||--/\/\/\--| gnd
      |         r1
      |
      +---===---| gnd
         /___\

   pin 1 - Vss (2-5vdc)
   pin 4 - audio out
   pin 5 - LED out
   pin 8 - ground

just do:

   ./program-p12f675.sh risingsun.txt

   or whatever song

   i think i put 3 songs, stjames.txt, swinglow.txt and risingsun.txt

thanks,
