Pet Repellent Spray

Cat repellent spray!
My cat, Ron, figured out that there were treats to be had on the counters and suddenly became impossible. We were having to close doors to keep him away from the kitchen. Such a pain.
This device uses a motion sensor to tell whenever he gets on the counter and spray compressed air to scare him off. It has been so effective over its first week of use that he completely avoids the counter and just having the device near by and not even powered up is enough.
In addition to the printed parts you will need:
3x m4 bolts
3x m4 nuts
1x PIR module
1x Arduino
1x Boost Converter
1x LiPo Battery
1x Charging module
a short length of string
wire, solder, hot glue etc.
The battery and charging module are not required and the device could be configured to work just from wall power using a USB charger port or a power bank.
Code and a build video will be uploaded to YouTube soon.
The blinker is optional. I added it after having the device running for a few days as people kept setting it off from walking around the kitchen. This makes the motion sensor more directional. It is just hot glued in place with a couple detentes to take the glue without showing it externally
