Cyber Fidget Docs¶

Cyber Fidget is a pocket-sized aluminum gadget with a screen, buttons, lights, a speaker and a slider that you can play with, and program to do new things.

In the clip: a small game made in the browser, running in the emulator (an on-screen copy of the device). The slider moves the paddle; catch the dots.

Got a kit? Put it together and turn it on

About 15 minutes with a small screwdriver. Then find your way around the built-in apps.

Make your first app

Write code in your browser and watch it run. Nothing to install, no device needed until the last step.

Build your first app | Make a game, step by step | Function reference
Make art for apps

Draw sprites (small pictures for characters and objects), animate them, or build 3D models, in the studio on cyberfidget.com.

Teaching or building with kids?

The browser path needs no installs and no device, and the tutorials say up front what you will be able to do. A teacher guide is in development, and we are looking for feedback and partners: teachers, schools, clubs and makerspaces who want to try it with learners.

At a glance¶

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

It ships as a kit: no soldering, just screws. 2.2 x 1.6 x 0.8 in, about 68 g. Inside: an ESP32 chip with Wi-Fi and Bluetooth, a 0.96" OLED screen, 6 buttons, a slider, 4 RGBW LEDs, a speaker, a microphone, a motion sensor, a microSD card slot, and USB-C.

See the Product overview for the full picture, or Hardware specs for part numbers and dimensions.

No device? No problem.

You can run real Cyber Fidget apps in your browser. Write or generate an app in the studio, press REBUILD & RUN in the welcome panel (or REBUILD in the emulator panel), and it runs in an on-screen emulator with the same buttons, slider, screen and lights. See the Browser Emulator guide.

Want to work on the firmware itself?

Most people never need this. The Arduino route installs firmware from your own toolchain, and the firmware on GitHub has the full source, the app functions and the emulator.
