Ring Video Doorbell / ghost rings with 16 VAC solenoid chimes [closed]
I have:
Ring Video Doorbell
(x4) solenoid chime operating on 16 VAC
The chime is a pre-2000's analog device. Presumably it uses an analog circuit to ring the solenoids in a pattern to make a ...

H-bridge with two logic-level GPIOs drawing high current
I am working on controlling a bi-stable latching solenoid with an H-bridge.
The microcontroller that I am using for my project doesn't have enough GPIOs for me to use four pins for the H-bridge, so I ...

Why is this Zener across the collector and emitter of this transistor driving a solenoid coil?
I am trying to understand a vintage (1970s) impact printer circuit. Each of the pins in the printer are driven by a small individual coil driver circuit, that was originally specified to look like ...

Why is this zener in series at the base of transistor, and has something failed?
I am debugging an ancient little impact printer and in my probing have found an unexpected voltage level. I'd like to understand this part of the circuit, why it's constructed as it is, and whether ...

Equation for the force created by a solenoid
I'm trying to make an electro-magnet and I want to figure out what core and wire I need using math instead of trial-and-error.
I want it to produce ~1.5 newtons of force at ~1.5 inches from the magnet....
