Yes, Andrew, I was also impressed by the complexity of this gadget. As for the pdf, we actually asked for a shorter version. In the end the production folks decided they could post the entire novel-length code.
Yes, it is a very cool gadget. The only thing I can say is that our cats would not wear it. They have destroyed all the collars we have gotten them. We also don't board the cats. They are easy to care for and we can get neighbors to come over and feed them.
Yes, I can understand what you're saying about cats, Naperlou. Over the years, my dogs have been fine with collars, but I've never even tried to get one of my cats to wear a collar. It will be interesting to hear what our gadget maker says about this.
If you want your cat to wear a collar, then it's best to start with them when they are young. They just expect that to be normal from then on.
If you try anything like this at home, then please do use a proper collar bought from a pet store. Cats can be strangled in the event they get it hooked up on a branch. That's extremely rare and can be avoided entirely by buying one designed to break when that happens. I just bought a cheap flea collar for this project. It is designed to expand and break under the weight of the cat.
@pete.cross: That's a very interesting master's thesis ("Control, communication and monitoring of intravaginal drug delivery in dairy cows"). I'd imagine that getting a cat to wear a collar is very simple in comparison.
The final showdown is under way in our first-ever Gadget Freak of the Year contest. Who will win an all-expenses-paid trip to the Pacific Design & Manufacturing Show? It's up to you, dear readers, to tell us.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
