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.

IoT-ifying old stuff is cool. Or even new, offline stuff. It seems to be a trend. And it’s sexy. Yes, it is. Why are people doing this, you may ask: we say why not? Why shouldn’t a toaster be on the IoT? Or a drill press? Or a radio? Yes, a radio.

[Dr. Wummi] just added another device to the IoT, the Internet of Thongs as he calls it. It’s a Philips MCM205 Micro Sound System radio. He wanted to automate his radio but his original idea of building a setup with an infrared LED to remotely control it failed. …read more
