Tonight I worked on getting the door lock actuator working so I could finally have my fire extinguisher effect.
essentially I just replaced the weak solenoid with the awesome door lock motor that Victor recommended. I got this one on Amazon for about $7 and free shipping!
here is the can data btw
and I made this little cheesy mount for my servo and switch
and closed via servo
this made the code very easy (and also the wiring – just hook up servo to the three pins on the servo controller, and battery 12v to the pushbutton switch. I moved the diode over to the actuator as well just in case)
here is a video of the first test
to secure the can I looped a dryer vent clamp through one of the iron uprights
you can see it here through the front large panel door
for now the servo and switch assemby are resting inside the large back panel of r2 at the bottom. I need to add a hinge to this door at some point.

what you can’t see it the clear hose running from the nozzle to the front top center vent
but it is there
