Eurorack Visuals Using Open Source SlimShader, Built on Raspberry Pis @Raspberry_Pi #PiDay #RaspberryPi
It’s that moment when you wander off the dance floor of an enormous music event. You want to escape the ridiculous wall of speakers and four to the floor EDM thump. You pass by the little bar, by the four couches set up in a corner somewhere, and down a dark hallway. At the end of the hallway you pull aside a dark red, sound dampening curtain. Inside there’s a musician standing in front of an modest Eurorack, modulating chill sounds as they move wires and plugs from one connection to another. And projected behind them is a screen with visualizations moving to the music, pulling you in like the journey into a monolith in orbit around Jupiter. The musician might just be using SlimShader. Here’s more form Erik Oostveen:
SlimShader is an Open Source Raspberry PI project based on glslViewer** capable of displaying OpenGL/GLSL shader files (stills or motion graphics). Shader files can be displayed “as is” or controlled in various ways: Manually (knobs), LFO (three digital low frequency oscillators), MIDI, Audio or CV. In this video we see the “Just Shaders” version in action. This version only requires you to power the Raspberry pi and hook it up to a HDMI monitor (or projector in these examples) and it will run randomly through all 200+ onboard shader files. The full version -the one with all additional controls- is still under development.

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, 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.
