Fidget spinners — so hot right now!
[Ben Parnas], and co-conspirator in engineering inanity [Greg Daneault], brought to the recent Boston Stupid Hackathon in Cambridge, MA, their IoT-enabled Fidget Spinner…. spinner. A Spidget Finner. Yep, that’s correct: spin the smartphone, and the spinner follows suit. Stupid? Maybe, but for good reason.
Part satire on cloud tech, part learning experience, a curt eight hours of tinkering brought this grotesque, ESP32-based device to life. The ESP can the Arduino boot-loader, but you’ll want to use the ESP-IDF sdk, enabling broader use of the chip.
Creating an app that pulls data from the phone’s gyroscope, the duo set up the spinner-bot to access the WiFi and request packets of rotational data from the smartphone via a cloud-based server — the ‘spincloud.’ Both devices were enabled as clients to circumvent existing IoT services.
[Parnas] stipulates that — theoretically — you could control as many spinners as you can imagine with this setup, but one is quite enough of a silly idea for us. Ridiculous or not — if you learn something, then it’s probably worthwhile! So keep hacking away at those ideas and you might be able to justify it to all the people with concerned stares.
To start, you can tell them you’re in good company.
