The @CheerlightsCat twitter account has privately been tweeting erratically the past few days while testing the software and control mechanisms. Now it is time to assemble the first prototype.

The main components include a Pi Zero, Pi Camera Module, WiFi dongle, PIR sensor.  I had imagined a hanging rope toy with a vibration sensor, but I was having trouble getting the gpiozero python library to respond to the switch. So now I present, a motion sensor in a box. Cindel the Cheerlights Cat loves this box. 

I traced a hole using the inside of a roll of scotch tape, made sure to stay inside the line while cutting, and then pushed the PIR dome into the hole to make a perfect fit.
