For Fab Academy we were required to complete a final project that incorporated many of the skills we had learned throughout the course. Inspired by a friend who had a radio in his bathroom that was always in and tuned to a jazz station. For my final project I decided to create a small bathroom radio that would turn on when you entered turn off when you left and have a few other fancy features. This page documents that project: Project Name: pJazz What will it do? * Play jazz music from a local FM station when you enter the bathroom. * Turn on based on input from a PIR sensor. * Turn off when you leave. * Display info on a small OLED display. * Diaplay RBDS info about the music if it’s being broadcast on the signal. * Display the current time (As the RBDS encodes this so why not) * Provide hands free interfacing with capacative touch proximity sensing Who’s done what beforehand? Here is a hack where someone wired a small portable mp3 player into their bathroom light on the ceiling. Example of interfacing a similar FM receiver chip with an Arduino. Arduino Shield with similar chip on board FM receiver chip. Designs for laser cut speaker enclosures are quite abundant. What materials and components will be required and where will they come from?
