HOW TO: Conductivity Tester
Multimeters are excellent tools for testing conductive materials, but they
are not objects you would typically carry with you. This experiment shows
how to build a pocket conductivity tester that is easy to bring to the fabric or
store and even to use in your studio.
Parts and materials:
• (1) sewable LED
• (1) alligator clip
• (1) CR2032 battery holder, preferably with on/off switch and wire leads
• (1) CR2032 battery
• Conductive-fabric tape with conductive adhesive
• Clear heat-shrink
Tools:
• Wire strippers
• Heat gun
Steps:
1. Gather your materials (Figure
A
).
2. Strip the ends of the ...
