  • We have a cat that would sit outside our bedroom door and cry incessantly for food promptly at 4:00 am. This was obviously driving us insane. In a sleep deprived stupor, I purchased a few items from Sparkfun (Ultrasonic sensor / 16x2 LCD / Voltage regulator / Power supply) and acquired a Particle Photon, 10V solenoid, a toilet flange from Home Depot and an air can. I can say that this sensor will most definitely detect cats. When triggered by the sensor, the solenoid pumps the air can for a quick second of PSSSSSSSTTT!!! followed by sweet silence. Thank you Sparkfun for a restful sleep!

No public wish lists :(
