Until the industrial revolution, humans made use of animals to make our labor easier. This is still seen in some niche areas, like how no machine yet has been invented that’s as good at sniffing out truffles as pigs are. [William] has hearkened back to humanity’s earlier roots, but in a more modern twist has made something of a general purpose dog that could feasibly do any work imaginable. Now his dog is remote-controlled.
[William] accomplished the monumental task in a literally cartoonish fashion using the old trope of hanging a hot dog in front of something’s face to get them to chase it. The attachment point was fitted with a remote control receiver and an actuator to get the hanging hot dog to dangle a little bit more to the dog’s right or left, depending on where the “operator” wants the dog to go. [William]’s bulldog seems to be a pretty good sport about everything and isn’t any worse for wear either.
Believe it or not, there has been some actual research done into remote controlling animals, although so far it’s limited to remote-controlled cockroaches. We like the simplicity of the remote-controlled dog, though, but don’t expect to see these rigs replacing leashes anytime soon!

We hear a lot about drone surveillance, drone package delivery, drone this, and drone that. Honestly, though, the best use of drones has been taking cool aerial videos and posting them online. Until now.
The US Fish and Wildlife Service plans to cover acres upon acres of prairie-dog habitat with vaccine-laced, peanut-butter coated M&Ms. The snacks also include a dye that will show up in the whiskers of prairie dogs that take the bait, allowing scientists to assess the efficacy of the program. And this is all in the name of saving endangered black-footed ferrets which share burrows with the prairie dogs. It seems they were getting the plague from the prairie dogs.
The quads are outfitted with a “glorified gumball machine” that spreads the vaccine tidbits around. Why a quad? They can cover more space with less disruption to the animals’ habitat. That’s a great application in our book.
But if you think this is a case of the USF&WS showing outrageous innovation, consider the way rabies was all but eliminated in Europe: throwing hundreds of thousands of vaccine-doped chicken heads out of helicopters across France, Switzerland, and Germany. You couldn’t make this up.

Cats do what they want, which rarely coincides with what their owner wants them to do. In [Dumitru]’s case, his girlfriend’s cat [Pufu] tended to make it outside into the cold more often than desired. Rather than settle with the normal bell which gets obnoxious even when the cat isn’t misbehaving, he decided to put together a custom Cat Finding collar. He used a PIC microcontroller as the brains, and temperature and light sensors to decide whether the cat had snuck into the cold, dark night. Once the cat has been marked as being outside, a buzzer and LED are set to go off at regular intervals until returned into the safety of the indoors.
[Dumitru]’s website along with his YouTube videos are in Romanian, though the schematics and source code provided speak for themselves. He does a wonderful job walking through the entire design process, including time spend in the IDE as well as EAGLE designing the board. YouTube has managed to subtitle the majority of the details, but we imagine this post will be a real treat to any Romanian speaking hobbyists out there. Be sure to catch both videos after the break.
