this multimeter hat allows me to visualize the conductivity of a material i’m holding in my hands. the only problem is that i can’t see the visualization myself since it happens ontop of my head. thus i rely on the faces of the people looking at me, interpreting their reactions.

the tip of this hat indicates electrical conductivity by lighting up more LEDs. the more LEDs light up, the more conductive the material in my hands is. the less LEDs light up, the more resistance there is in the material i’m holding in my hands. bellow a sketch of the circuit:

i made this hat to aid me in my introductory demonstration of various etextile materials such as conductive fabrics and threads. here a photo taken from the absurd hackathon:

it is also the perfect tool for using in my Meet the Materials series:

it also features as a tool in my Material_Adventures boardgame as a means of meeting the materials halfway:
