-===== Networked Metronoms =====
+===== Networked Metronomes =====
+==== The idea ====
 A couple of months ago we were asked by Ward Weiss if we wanted to participate in his [[https://www.artsbirthday.net|Art's Birthday]] Project called [[https://planktone.be/planktijd/|Planktijd]].
+//Once, in the deserted streets of seized Leningrad, the synchronized ticking of metronomes served as a powerful symbol of resistance against oppression and a beacon of hope for the future.
+Through its regular ticking, PLANKTIME reminds us of the enduring spirit of those who refuse to be silenced and continue to fight for freedom, free thought and democracy.
+On the Tokelau atoll, where each new day commences, a PLANKTIME server selects 24 random "tick" intervals at midnight. These intervals can range from a single tick to a maximum of one minute of continuous ticking. The active replicas have the autonomy to either adhere to or disregard these designated moments.//
+On the [[https://planktone.be/planktijd/DIY.html]] website it is fully explained how to make one. Of course we could not refuse his beautiful offer!
+==== Possible and Imaginary Steps ====
+  * order the right ESP32
+  * solder an ESP32 and relay, install the code and play
+  * change/extend the relay with a solenoid that can tick against objects (wood, glass, metal, etc..), and stream that sound online
+  * use this device to make our own rhythms/timings, algorithmically generated but based on the participants from ButtuLab, and use a streambox to transmit this, but that is a matter of sitting together and do some programming sessions, I am sure we can come up with a nice distributed composition!
+  * same thing as above, but this time go outside and play with 'found resonating objects' in nature, and connect/transmit/stream via streamboxes, maybe we could at that moment try to develop a new streambox?
+Some general links and things:
+ESP32 (the newest one is ESP-S3 but that is overkill for this I think). There are many models available, even from Espressif, and keep in mind to check the right pins, the Chinese clones can be quite different, watch out! You need a 38 pin model...

+Check the pdf, we can use a transistor and solenoid and make different sounds...
+Solenoids exist in all voltage ranges, we could use the relay above but still you would need extra power externally, to avoid it we look into 3V or 6V

+It's an ESP32 so we can run it on a solar panel, but need a new lipo-rider-pro

+I guess we are having a 5V one and also some regulators, keep it easy though using a simple Low-dropout or LDO Regulator MCP1700-3302E ??? check circuitry for connecting to ESP32
