hi there
https://forum.allaboutcircuits.com/...lenoids-for-kinetic-sculpture-project.140630/
following on from the above thread, i am now further on in this kinetic sculpture project which uses a motorized hoist to move an accordion in and out and 16 solenoids which press keys on either side of the accordion to generate sound, all controlled via a Crestron touchpanel. I have made code for the Crestron processor which then (at the moment) makes the solenoids play chords or arpeggios, or single notes.
At the moment it is a matter of working out which combination of key presses works best with the piece. Although I have run into a problem which hopefully someone here can help me with :
if i have a button on the touchpanel which makes three solenoids press three keys on the accordion to play a chord, which sounds whilst the accordion moves in and out, after about a minute or two the solenoids get very hot, and the other day while testing them, three of them actually burnt out as they were 'high' for too long.
my power supply is a 12v 15A PSU, like this one : https://www.ebay.co.uk/itm/DC-5V-12...hash=item25d974fd0e:m:mXMYO2lbiTGq8KoJbasPG4Q
the solenoids i am using are these ones : https://www.ebay.co.uk/itm/JF-0530B...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
from speaking with a friend who is helping me with the code, it seems i might need a resistor or something in the circuit to stop the solenoids overheating when they are being held 'high' for too long.
can anyone offer any advice to help me solve this problem? if you need any more information please let me know
thanks
