Product Overview¶

A machined-aluminum, pocket-sized gadget built for play, tinkering, and experimentation. Designed and assembled in Michigan.

What is Cyber Fidget?¶

Cyber Fidget is two things at once:

An electronic fidget toy — beyond a spinner or clicker, something with a screen, buttons, LEDs, and sound that's fun to hold and play with
An approachable dev board — with everything already included: display, buttons, slider, speaker, mic, accelerometer, LEDs, SD card, Wi-Fi, and Bluetooth

It's meant to feel good in your hands, be easy to use without knowing how it works, and be fully hackable when you're ready to dig in.

What's in the kit¶

Cyber Fidget primarily ships as a self-assembly kit — no soldering, just screws. The kit includes:

Machined aluminum chassis (front and back)
Assembled PCB with all components pre-soldered
Buttons, slider, and hardware
Screws and fasteners
Interchangeable screen color filters

Assembly takes about 15 minutes. See the Assembly Guide for step-by-step instructions with photos.

Made for tinkerers¶

Every screw and part is accessible. The enclosure is built to be opened, explored, and modified:

Re-color it — swap screen colors (blue, red, teal, and more)
Redesign it — 3D print your own backplate or case modifications
Hack it — apps run off the SD card (soon) or integrate with the source code
Learn from it — ideal for learning how to code, embedded systems, sensors, and human-machine interfaces

Software¶

The firmware ships with 28+ built-in apps (games, screensavers, tools, examples). You can also write your own using the App Builder in your browser or by cloning the firmware repo.

Best experience with VS Code + PlatformIO (via pioarduino). CircuitPython hardware support is designed-in but currently untested.
