I have wanted to make one of these for years.
the only difference is that I was going to control it from my phone so I could push the trigger button myself.
I was also going to sample the old berzerk arcade game
and make it say “Intruder Alert! Intruder Alert! Targeting Intruder”
then make it count down from 5.
intruder alert... then the red bouncing ball would take him out...
hehehe
Looks good, the only problem I can foresee would be it opening fire on police, fire or other first responders who are just doing their job. Amazon drivers could also be targets.
I don't think they would be amused.
