Psychedelic Bong Smoke Machine Thing + Treasure Hunt
Bend / flex sensor 4.5″: ($9.95) As the sensor is flexed, the resistance across the sensor increases.
Electroluminescent “wire” (EL-wire) 3.2mm ($1.50): A wire that gives off a bright neon light glow.
Alcohol sensor: Sensor provides an analog resistive output based on alcohol concentration.
Fiber optic cable ($0.50): functions as a “light guide,” guiding the light introduced at one end of the cable through to the other end.
Conductive fabric ($3.95): a device used to prevent electrostatic discharge (ESD) by safely grounding a person working on electronic equipment
Conductive paint ($7.50):
Neodymium magnets ($.0.10): currently the strongest type of permanent magnet.
Copper foil ($1.09): 0.003″ Thick x 3″ wide
Peltier Junction ($12.95): the direct conversion of temperature differences to electric voltage and vice versa. Can be used to generate electricity, to measure temperature, to cool objects, or to heat them or cook them.
