Motorized Spray Can Cap Trigger

While designing my own I figured Idgive the web a look see… Welp… great design! Im working on a circuit that will modify the swing of the horn on the fly.

Used this to make a Get-Off-The-Table-You-Dumb-Cat mechanism with some micro controller magic (ESP-8266). It is triggered by an ultra sonic distance measuring sensor, that can be set to whatever your needs are i.e. width of the table. It lest out a short burst of compressed air to keep my cat off the kitchen table. Works very well. Still in the testing stage at this point. (edited)
