Drones Rain Down Rat Poison On The Galapagos

If your favorite movie is Ratatouille, now would be a good time to read a different article. Rats on the Galápagos Islands are an invasive species and eradication is underway. This is not a first for the islands, and they are fiercely protected since they are the exclusive home to some species including the distinctive tortoise from which the island derives its name and of course finches. Charles Darwin studied the finches while writing On the Origin of Species. So yeah, we want to keep this island from becoming unbalanced and not disturb the native wildlife while doing it. How do we check all these boxes? Technology! Specifically, hexacopters carrying rat poison.

The plan is simple, drive a truck to a central location, release the hounds drones and fifteen minutes later they come back after flying high above the indigenous wildlife and dropping pest control pellets. The drones save time and labor, making them a workhorse rather than a novelty. This work experience on their resume (CV) could open the door to more dirty work or more wholesome activities. Who is to say that the same drones, the exact same ones, couldn’t deliver plant seeds, or nourishing food to the dwindling species harmed by the rat population explosion.

What would you deliver with drones? How about providing parcels or just learning a better way to navigate?

They’re Putting Soy In Your Wires, Man

I’ve got a friend who tells me at every opportunity that soy is the downfall of humanity. Whatever ails us as a society, it’s the soy beans that did it. They increase violent tendencies, they make us fat and lazy, they run farmers out of business, and so on. He laments at how hard it is to find food that doesn’t include soy in some capacity, and for a while was resigned to eating nothing but chicken hot dogs and bags of frozen peas; anything else had unacceptable levels of the “Devil’s Bean”. Overall he’s a really great guy, kind of person who could fix anything with a roll of duct tape and a trip to the scrap pile, but you might think twice if he invites you over for dinner.

A column of soy soldiers stand at the ready.

So when he recently told me about all the trouble people are having with soy-based electrical wiring, I thought it was just the latest conspiracy theory to join his usual stories. I told him it didn’t make any sense, there’s no way somebody managed to develop a reliable soy-derived conductor. “No, no,” he says, “not the conductor. They are making the insulation out of soy, and animals are chewing through it.”

Now that’s a bit different. I was already well aware of the growing popularity of bioplastics: the PLA used in desktop 3D printers is one such example, generally derived from corn. It certainly wasn’t unreasonable to think somebody had tried to make “green” electrical wiring by using a bioplastic insulation. While I wasn’t about to sit down to a hot bag of peas for dinner, I had to admit that maybe in this case his claims deserved a look.

Automated Humane Pest Control

rat_trap_2000

[Tobie] seems to have a bit of a rat problem.

While most people would be inclined to simply buy the oversized Victor spring-loaded rat traps and call it a day, [Tobie] is a bit more humane. To help remedy his problem while also ensuring that no rats are harmed in the process, he built the Rat Trap 2000.

Self-described as completely over the top, the Rat Trap 2000 lures the rodents into its containment area with apples and corn, securing them inside using a servo-actuated trap door. The door is triggered by an Arduino that monitors the holding pen for movement using an IR sensor. All of the action is captured on video using the web cam on his Eee-PC, as you can see in the very short video below.

This certainly isn’t the most cost-efficient way to control your vermin problems, but if you’ve got some spare parts laying around, why not? It’s far more humane than some of the other rodent control solutions we have seen, and it sure beats living with rats!
