Fidget spinners are not only a fad, but pretty much useless. Sounds like a job for hacking to make the toys have some actual purpose. [D777k] took up the challenge and created a MIDI controller from a common spinner. You can see a video of the results, below.

The device uses a LightBlue Bean controller and Garage Band as the MIDI software. Granted, it might not be super useful, but it is better than just a plain old spinner. [D777k] calls it a “whirling dervish of sound making!

The Arduino code that drives the thing is very simple. It reads three axes of acceleration and uses that to drive the MIDI software. When the acceleration exceeds a threshold, the software creates a new note based on the sums and differences of the accelerations.

The Lightblue Bean isn’t anything new, but it is well suited for this kind of service. Certainly, making a toy into a MIDI controller isn’t an original idea, either. But it sure is fun.

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 inĀ  good company.
