I was looking for a fun project to create with one of the first Raspberry Pi’s I ever got. I soon realized the potential of the development board, but was long searching for a really nice project. I came across a YouTube post from Kyle Prier where he created a proof of concept streaming internet radio.
While recreating the project I soon realized that some of the code could be improved, for example shorten the initial loop, refactor the LCD code into its own library and use interrupts to check for button presses.
When the project became more and more stable I began to research the way to package it into a real device instead of having to use the breadboard permanently. That gave rise to research speakers, drivers and the way to construct them from scratch. I wrote a program to calculate the optimum volume for the speaker enclosure and how to vary width, breadth and depth while keeping the fixed volume (something I did not find the tools for online).
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
