making a synth with (found) plaster and digital synthesis connect to teensy circuit
Teensy controller make a mold
conductive thread Make a mold using for example clay, Take any shape you want to create your instrument with and cast it in the clay.
connect your circuit to an audio device
Mix plaster with water

Take a microcontroller (preferably a teensy duino since it has a lot of touch sensors implemented) and connect your plaster casts to it.
Get yourself a bowl and fill it with the right amount of water needed to cast your mold into plaster. add plaster to the bowl with a ratio of 2:3 untill you see little islands create on top of the water. then mix it with a spatula.
Connect your micro-controller to a sound device and you can start coding and testing while receiving feedback. (coding works best with the teensyduino and pjrc liberarys.step by step coding guides can be found on the webside)
(be carefull! the moment you mixed the two the procces of hardening begins)
pour the plaster mix into the mold
start exploring the code Pour your plaster mix into your mold and wait untill the plaster is solid as a rock (you can check if the plaster is ready by gently pressing your nail in it, does it leave a mark? wait i little longer.

keep exploring your self made instrument, try out new code, frequencys and maybe vcv rack since you can recreate everything done in that application with the pjrc librarys keep on going untill satisfied.
