The Magic Flute of Rat Mind Control Aims to Mix Magic and Science

Well this is unusual. Behold the Magic Flute of Rat Mind Control, and as a project it is all about altering the response to the instrument, rather than being about hacking the musical instrument itself. It’s [Kurt White]’s entry to the Musical Instrument Challenge portion of The Hackaday Prize, and it’s as intriguing as it is different.

The Raspberry-Pi controlled, IoT Skinner box for rats, named Nicodemus.

[Kurt] has created a portable, internet-connected, automated food dispenser with a live streaming video feed and the ability to play recorded sounds. That device (named Nicodemus) is used as a Skinner Box to train rats — anywhere rats may be found — using operant conditioning to make them expect food when they hear a few bars of Black Sabbath’s Iron Man played on a small recorder (which is a type of flute.)

In short, the flute would allow one to summon hordes of rats as if by magic, because they have been trained by Nicodemus to associate Iron Man with food.

Many of the system’s elements are informed by the results of research into sound preference in rats, as well as their ability to discriminate between different melodies, so long as the right frequencies are present. The summoning part is all about science, but what about how to protect oneself from the hordes of hungry rodents who arrive with sharp teeth and high expectations of being fed? According to [Kurt], that’s where the magic comes in. He seems very certain that a ritual to convert a wooden recorder into a magic flute is all the protection one would need.

Embedded below is something I’m comfortable calling the strangest use case video we’ve ever seen. Well, we think it’s a dramatized use case. Perhaps it’s more correctly a mood piece or motivational assist. Outsider Art? You decide.

Do you like badges? Of course you like badges. It’s conference season, and that means it’s also badge season. Well good news, Tindie now has a ‘badge’ category. Right now, it’s loaded up with creepy Krustys, hypnotoads, and fat Pikas. There’s also an amazing @Spacehuhn chicken from [Dave]. Which reminds me: we need to talk about a thing, Spacehuhn.

On the list of ‘weird emails we get in the tip line’ comes Rat Grease. Rat Grease is the solution to rodents chewing up cabling and wires. From what we can gather, it’s a mineral oil-based gel loaded up with capsaicin; it’s not a poison, and not a glue. Rats are our friends, though, which makes me want to suggest this as a marinade, or at the very least a condiment. The flash point is sufficiently high that you might be able to use this in a fryer.

[Matthias Wandel] is the guy who can build anything with a table saw, including table saws. He posts his stuff online and does YouTube videos. A while back, he was approached by DeWalt to feature their tools in a few videos. He got a few hand tools, a battery-powered table saw, and made some videos. The Internet then went insane and [Matthias] lost money on the entire deal. Part of the reason for this is that his viewers stopped buying plans simply because he featured yellow power tools in his videos. This is dumpster elitism, and possibly the worst aspect of the DIY/engineering/maker community.

Elon Musk is the greatest inventor ever. No scratch that. The greatest person ever. Need more proof? The CEO of Tesla, SpaceX, and our hearts has been given the green light to build a high-speed underground train from Chicago O’Hare to downtown. Here’s the kicker: he’s going to do it for only $1 Billion, or $55 Million per mile, making it the least expensive subway project by an order of magnitude. Yes, Subways usually cost anywhere between $500 to $900 Million per mile. How is he doing it? Luck, skill, and concentrated power of will. Elon is the greatest human ever, and we’re not just saying that to align ourselves with an audience that is easy to manipulate; we’re also saying this because Elon has a foggy idea for a ‘media vetting wiki’.

There are rumors Qualcomm will acquire NXP for $44 Billion. This deal has been years in the making, with reports of an acquisition dating back to 2016. Of course, that time, the deal was set to go through but was apparently put on hold by Chinese regulators. Now it’s the same story again; there were recent rumors of Qualcomm buying NXP, and the story was later changed to rumors. We’re waiting for an actual press release on this one. It’s just another long chapter in the continuing story of, ‘where the hell are all the Motorola app notes and data sheets?’
