Hey everyone. New to the group. Just created an account to ask the pros how to get this created.
Right now I have an alexa momentary switch that turns in for 2 second then shuts off. That is hooked to a motor that spins and when it spins it lifts the flap on the toilet and ideally it would stay open for a few seconds then close. Currently it just spins and doesn’t always come back around and stop so the flap doesn’t close correctly.
Do they make a lifting lever motor or something that would lift a chain inside the toilet and when the voltage is lost, it will go back down on its own. Something that has maybe a 45 degree lift
As we understand, you would need the motor to rotate in both directions (CW and CCW). For this, you would need to reverse the polarity of the motor by using two SPDT relays or one DPDT relay.
If this is doesn’t answer your question, please post a diagram/schematic of what you are planning to accomplish so that we better understand your requirement.
thanks for the reply. I was also looking at push/pull solenoids as it doesn’t take much force to lift the chain in the toilet to let the water out. would a 3-5 solenoid work in theory hooked up to a relay that opens for 3 second or so?
Okay I need help picking out a servo that will work.
Here is what I have.
10-11lbs of water on top of the flapper. Chain is 6inches long. I need a servo that will lift the chain a inch and hold it there for 3 seconds then let back down.
A servo rated for 10Kg-cm should be enough to lift the flapper. Will the servo be inside of the water tank ? If so, you will need a Waterproof servo. This Hitec HS-5646WP Waterproof, High Torque Digital Servo could be a good option.
Also, please know that a relay won’t be able to control an RC servomotor. To drive an RC Servo you would need an RC Servomotor Controller as servos are controlled with PWM signals instead of a DC Voltage (as DC Motors).
Here is a nice article that explains the differences between motor controllers.
