feeding the darts into the acceleration firing chamber
(Figure 7). A spring in the dart clip pushes each dart up
until the servo motor grabs the dart and shoves it in the
acceleration firing chamber.
Disable the jam clearing door safety switch by inserting
it backwards in its housing (Figure 8). This will enable the
gun to run and fire continuously. Next, attach a 5V relay to
the trigger switch. You can opt to enable the relay either
with a dedicated I/O pin on your microcontroller (so that
you can fire the gun via your Wi-Fi web browser interface)
or with a heat-seeking passive infrared (PIR) sensor.
No matter which method you select for firing your soft
blue missiles, the remaining output pole of the trigger
switch is connected to one terminal on the servo motor
Finalize the connection of the servo motor to any GND
terminal inside your gun’s power supply. Remember, you
could try to use a sealed lead-acid 12V battery for powering
your entire project with the appropriate buck voltage-reducing circuits for the motors, microcontroller, and motor
Armed with this heavier artillery, there will be no
stopping you from scaring every four-legged creature away
from your precious vegetables. But why stop there?
Next up: those pesky pigeons that think your house
roof is their lavatory. Now, I just need some sticky treads.
