Make Halloween Prop Motion Detectors Work in the Dark

Показать описание
Most halloween props use motion sensors that don't work in the dark! This DIY Halloween hack converts your prop to use a PIR motion detector module that triggers even in complete darkness.
This method should work with most halloween props that have a test button feature, even if the original prop doesn't have a motion sensor.
This is a DIY electronics project! You will need enough electronics knowledge to read a schematic and solder together the components as indicated. Creativity in hiding the sensor also helps!
Schematic:
Voltage Regulator:
Note: in the video I claimed the LM2596 can step voltage up or down. Apparently it only steps down, but it still worked great for me.
100K Potentiometer:
2N3906 PNP Transistor:
Not too picky here, any PNP transistor with "typical" characteristics is likely to work.
PC817 Optocoupler:
You can sub in a different part here too, just check the datasheet.
Resistors (if you don't already own a kit):
LED (optional):
