Housings

• We have been using ‘postal tubes’ as the main housing for the sound making circuits thus far.  These can often be freely obtained from Fedex or similar.  One each circuit, something similar to this, pehaps:

Arty/Crafty Materials

• Paints and papers and such around for decoration of instruments after they’re made.  Spray paints are also fine, colored electrical tape is a favorite, and glue is a must.

Prototyping Tools - A few tools, for general assembly and making of the instruments:

• Wire Strippers:
