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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
