Halloween props timer control (animated, delay, motion, sensor, detector)
Use this "timer control" to
control the activation or duration of any electrical controlled Halloween prop. The timer control uses 110v AC household current and outputs the same. There are two ways to use the control using one of
two outputs (or both). One output is live (on) when power is applied to the input. The other output is dead (off). Set a time delay between 1-10 seconds using the knob on the timer control. When power is
applied to the input, power will flow to the live output for that many seconds, then power is cut off. The other output is dead when power is applied to the input for that many seconds, then the power is
applied and left on.
Here is an example. Say a red lamp is plugged in the live output and a green one in the dead output. The control is set to 5 seconds. When you plug in the cord into a
household outlet, the red lamp turns on for 5 seconds. At the 5 second moment, the red lamp turns off and the green lamp turns on and stays on as long as the control is plugged into the outlet.
Why do you need a control like this? Typically, a prop is triggered for a specific amount of time, then powered down, allowing the prop to reset for the next victim.
A typical configuration is to
use a motion detector/sensor setup that allows your prop to receive power. There are several “how tos” on the web that will show you how to create motion detector “switch” that will power your prop when
motion is detected. Some motion detectors have a “test” switch to allow power only to be supplied for a brief time. Some have settings for 1, 5, 10 minutes etc. If your props are pneumatic (air
controlled) with some sort of solenoid valve using 110v power, having your prop triggered for 1, 5, or 10 minutes is not desired (too long). Usually you want a momentary trigger, allowing the prop to
popup, or active for a brief few seconds then reset. Maybe in another configuration, you want your prop to have a delayed activation. In either case, you can plug this control into your motion detector
configuration and then plug your prop(s) into the outputs of the control.
Your our prop is powered by 24v DC? No problem, just use a wall wart (transformer), plugging it into one of the outputs.
The control consists of a solid state timer and relay that is used in manufacturing applications. These controls themselves cost $20-$80 depending on where you find them (used/new).
The relay in the control are rated 120v AC – 10amp.
