I frequently think about how lucky I am that my dopamine rush is linked to seeing projects finished. People ask me how I get so much done, but there really isn't much of an answer other than "I like doing them and I enjoy seeing them finished".

Here's a beeping ball toy I made for my blind cat yesterday:

Very cool! How did you make this? I wonder if having the vocalizations of a prey animal (i.e. mouse) would provoke a stronger response in your cat than a generic beeping.

I used an ESP8255, a motion sensor (a spring in a tube with metal walls) and a buzzer. Something better-sounding than a beep would definitely be preferable, but I don't think the buzzer can really play anything other than a beep...

I'll have to do some research, maybe it can do some rough approximation, thanks for the idea!
