I have a snake at home that is always disappearing. I want to build a GPS like system for my home that will help me find it. to tell you the truth, I usually find it very fast, I am more interested in making the device than I actually need it.
You didn't indicate where you live, that would help me out as I would make sure not to go live near you.
I would suggest attaching a small bell to the snake so that not only you can trace it but everyone on its path.
A friend way back during high school and shortly after we graduated from high school, had about a 6' boa constrictor. One day he was tangled up in the springs of a couch, but the most memorable day was where do you put the snake when your having a party?
Well, it was in the only bathroom in his apartment and he was curled around the outside of the medicine cabinet. I didn't bother him and he didn't bother me when i used the facilities.
