About Galactic Unicorn

Galactic Unicorn offers 53x11 bright RGB LEDs driven by Pico W's PIO in addition to a 1W amplifier + speaker, a collection of system and user buttons, and two Qw/ST connectors for adding external sensors and devices. Woha!

🔗 Galactic Unicorn store page

Galactic Unicorn ships with MicroPython firmware pre-loaded, but you can download the most recent version at the link below (you'll want the galactic-unicorn image).

Galactic Unicorn and PicoGraphics

The easiest way to start displaying cool stuff on Galactic Unicorn is using our Galactic Unicorn module (which contains a bunch of helpful functions for interacting with the buttons, adjusting brightness and suchlike) and our PicoGraphics library, which is chock full of useful functions for drawing on the LED matrix.

Examples

Clock

clock.py

Clock example with (optional) NTP synchronization. You can adjust the brightness with LUX + and -, and resync the time by pressing A.

CO2

co2.py

Add a SCD41 sensor breakout to make an unsubtle carbon dioxide detector. Press A to reset the high/low values.

Eighties Super Computer

eighties_super_computer.py

Random LEDs blink on and off mimicing the look of a movie super computer doing its work in the eighties. You can adjust the brightness with LUX + and -.

Feature Test

feature_test.py

Displays some text, gradients and colours and demonstrates button use. You can adjust the brightness with LUX + and -.

Feature Test With Audio

feature_test_with_audio.py

Displays some text, gradients and colours and demonstrates button use. Also demonstrates some of the audio / synth features.

Button A plays a synth tune
Button B plays a solo channel of the synth tune
Button C plays a sinewave (it's frequency can be adjusted with VOL + and -)
Button D plays a second sinewave (it's frequency can be adjusted with LUX + and -)
Sleep button stops the sounds

Fire Effect

fire_effect.py

A pretty, procedural fire effect. Switch between landscape fire and vertical fire using the A and B buttons! You can adjust the brightness with LUX + and -.

Lava Lamp

lava_lamp.py

A 70s-tastic, procedural rainbow lava lamp. You can adjust the brightness with LUX + and -.

Light Sensor

light_sensor.py

Reads data from the on board light sensor and displays the brightness level of the environment. The display is by default set to auto brightness i.e reacts to the brightness of the environment.

Button A turns auto brightness off
Button B turns auto brightness on

Nostalgia Prompt

nostalgia_prompt.py

A collection of copies of classic terminal styles including C64, MS-DOS, Spectrum, and more. Images and text are drawn pixel by pixel from a pattern of Os and Xs. You can adjust the brightness with LUX + and -.

Rainbow

rainbow.py

Some good old fashioned rainbows! You can adjust the cycling speed with A and B, stripe width with C and D, hue with VOL + and -, and the brightness with LUX + and -. The sleep button stops the animation (can be started again with A or B).

Scrolling Text

scrolling_text.py

Display scrolling wisdom, quotes or greetz. You can adjust the brightness with LUX + and -.

Wireless Examples

These examples require WIFI_CONFIG.py and network_manager.py (from the common directory) to be saved to your Pico W. Open up WIFI_CONFIG.py in Thonny to add your wifi details (and save it when you're done).

micropython/examples/common

Cheerlights

cheerlights.py

Displays the most recent #Cheerlights colour. Find out more about the Cheerlights API at https://cheerlights.com/

Cheerlights History

cheerlights_history.py

Updates one pixel every five minutes to display the most recent #Cheerlights colour. Discover the most popular colours over time, or use it as an avant garde (but colourful) 53 hour clock! Find out more about the Cheerlights API at https://cheerlights.com/

You can adjust the brightness with LUX + and -.

Galactic Paint

galactic_paint

Draw on your Galactic Unicorn from another device in real time, over wifi!

Requires WIFI_CONFIG.py from the common directory. It also needs the micropython-phew and microdot libraries (you can install these using Thonny's 'Tools > Manage Packages').

Other Examples

Launch (Demo Reel)

launch

If you want to get the demo reel that Galactic Unicorn ships with back, copy the contents of this launch folder to your Pico W.
