I've added a simpler stopping method using pstn, now just spark the red spot and wait, to restart just spark the green again
I just found a simpler way, fill the box with nscn, erase nscn, put i pixle of pscn on switch, spark to restart mixer.
there is a way to stop it, there is a red box in the top right, hold ctrl and shift and click (drawing with nscn) it fills the box with nscn, which shuts off the switch, stopping the mixer. to restart erase the nscn, add a pixel of pscn on the switch, pause, spark the pscn, press 'f' once, then type in console " !set type sprk none " and hit enter. then close the console and unpause, the mixer should be reset.
Btw nice save but it will be even better if you add a way to stop the mixer
