NFC Radio for children

thingiverse

This is a highly customized version of "Speaky: The DIY Airplay Speaker" by "TheNewHobbyist". My main goal was to create a radio that my two-year-old daughter could easily operate, so she could select the music or radio station she prefers. The slot on top is used for inserting NFC tags, which are laminated between two sheets of paper (about 5x5cm) showing the content to be played. The media can be stored on the internal SD card or streamed from podcasts or Google Music. The speaker grills are simply decorative; I recommend printing them in a different color. The narrowed window also looks nice when printed in another color, and it helps if you later decide to use smaller NFC tags (as happened in my case). The following components are used: Raspberry Pi NXP Explore NFC Shield Trust Remo 2.0 Speaker Set (you have to remove the case) Optional: USB sound card for improved audio quality USB wifi adapter to improve signal strength I'm sure there are many details about the design that can be improved, but as this was my first project in 3D modeling, I am very pleased with the results. UPDATE: I recently printed a second radio and encountered issues with bed adhesion of the supports for the nuts in the housing. Therefore, I removed the "inner" grills, which were basically only there due to historical reasons. I just hadn't initially planned to print additional ones. As a second optimization, I added supports for the nuts within the model. So using the revised model supports should be necessary only for the "card compartment". One more tip after printing the second version: If the screws are too tight to screw them in, try printing them at 95% scale. I ran into this problem.
