cyberDÛCK – a self-contained computer that edits and runs #CircuitPython

cyberDÛCK is billed as a self-contained computer that can edit and run Python files, with USB keyboard input and a display. And it’s shaped like a disaster-recovery duck –, and YouTube.

Key features:

  • USB Keyboard input
  • Display for showing output
  • A text editor for creating and editing Python code
  • A “REPL”-like command line for entering Python commands (to edit a file, run a file, etc.)

The project deliberately takes bits and pieces from others to make it work.

  • Use a co-processor to take input from a USB keyboard (Arduino-based USB Host for SAMD with software modified from code by gdsports)
  • Transmit keyboard input to main processor using UART
  • Use a “REPL-interceptor” to allow text input from UART to control the command execution of python input from the keyboard
  • Adapt a text editor MicroPython-editor (pye) from robert-hh to run on a CircuitPython Board with attached display. This will edit files by taking input from UART and output to the attached display. File storage is using on-board non-volatile memory or a memory card

Inside it has two tiny, powerful Adafruit ItsyBitsy M4 microcontrollers.

Join Adafruit on Mastodon

Adafruit is on Mastodon, join in!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
