This is a heavily modified version of "Speaky: The DIY Airplay Speaker" by "TheNewHobbyist".
My goal was to create a radion which my 2 year old daughter could operate, so she would be able to select the music or radio play as she prefers.
The slot on the top is used to insert the NFC tags, which are laminated between two sheets of paper (about 5x5cm) showing the content to be played. The media is stored on the internal SD card or streamed from podcasts or Google Music.
The speaker grills are just for the looks. I recommend printing them in another color.
The narrowed window also looks nice of printed in an other color, but also helps if you later decide to use smaller NFC tags (as happened in my case).
The following internals are used:
- Raspberry Pi
- NXP Explore NFC Shield
- Trust Remo 2.0 Speaker Set (you have to get rid of the case)
- USB sound card for improved audio quality
- USB wifi adapter to improve signal strength
I am sure there are lots of details about the design which can be improved, but as this was my first project in 3D modeling, I am very happy with the results.
Printed in PETG, but should not make a difference.
Supports should only be necessary for housing.
Back and housing screw together.
Please use the screws provided by "TheNewHobbyist" at his design "Speaky: The DIY Airplay Speaker".
The speaker grills have to be glued in place.
The window is a press fit or can also be fixed with some glue.
The Knob is also a press fit on the volume control of the speaker set I used.
