- Simple song selection with big buttons: button 1 selects folder one, first song, press button 1 again and it jumps to second song in folder 1.
- Web interface where parents can
- control volume (limit) to protect hearing,
- skip super annoying songs remotely (important!)
- set daily maximum playtime
- see usage statistics;-)
- Super crispy OLED display showing

- image per folder or song
- weather information;-)
- night light (a star for night time, a sun for daytime to let the kid know wether it is time to get up)
- Powered by rechargeable LiPo power pack
After setting up everything on a prototyping board I continued to soldering everything together on a prototyping PCB and all the components seem to work together perfectly. I can already play one song per button from the SD card, volume of the tiny loudspeaker is perfectly sufficient. Especially new to me was to use the ADC and some resistors to “multiplex” the six buttons into just one input pin.
Not just winter is coming but also christmas and the FairyBox is supposed to be a christmas present for my daughter. So, for a “production” ready FairyBox I still need a lot of programming and also to put the hardware in a nice casing that deserves the name FairyBox. BTW: the price for the hardware components is in the sub USD $30 area so far! Stay tuned!

|Prototype setup: it works! Now “just” programming required|
A ridiculous amount of coffee was consumed in the process of building this project. Add some fuel if you'd like to keep me going!
