The PI Radio Case was designed to create a small, easy to use radio with decent sound. It uses the PhatBeat header from Pimoroni (its great), which can either be purchased alone or as as part of a Pi Radio kit, full links are below. It will of course work with any other audio output from a Raspberry Pi Zero.
The speaker has been replaced with a Surface Transducer, allowing a smaller case as well as making use of what ever surface the radio is placed upon to enhance the sound. The transducer is at the bottom of the unit as a small metal disc, placing it on a wooden surface creates the deepest sound, a sound beyond the size of the device.
The buttons are ‘mini arcade’ buttons, aimed at simplifying the operation of the radio – it features play/pause (Yellow), next station (Blue) and Volume up (Red), Volume Down (Green). There is no power off in the current version as its built to be left powered for instant audio (although the feature is built into the PhatBeat so can be easily extended). The wiring is as per the PhatBeat output pins. See the Radio Kit for the full software install and full details on how to get the radio working.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
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.
