CompuCanvas – wall art canvas enclosures for Raspberry Pi systems #RaspberryPi #Art @Raspberry_Pi
CompuCanvas is a system of networked Raspberry Pi computers with peripherals as art by Chris Daly. The peripheral devices incorporated into CompuCanvas systems have been selected (among other factors) because they can be controlled in a straightforward way from the command line.
CircuitPython devices from AdaFruit (running the 2.0.0 firmware), like the Trinket M0, Gemma M0 and Circuit Playground Express offer 2 distinct modes of command line control. First, the device mounts as a USB drive at /media/pi/CIRCUITPY(additional devices at CIRCUITPY1, CIRCUITPY2, etc.). This directory contains a main.py Python file which is run every time the device resets. Editing and saving main.py will force a reset and then run the new version.
The CircuitPython device also appears at /dev/ttyACM0 (or ACM1, ACM2, etc). Run the command screen /dev/ttyACM0 and then press Ctrl-c and Enter once or twice and you should see a >>> Python REPL prompt.
The code is all on GitHub under a Eclipse Public License – v 1.0 license. See the repo for various CompuCanvas models.
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 code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
