toddlerMusicBox Musicplayer

After building tmb One and Two I was thinking about what could be done better. One main concern I had was the booting time of the RaspberryPi. I wanted to have an immediate response after power button was switched on. So I started the tmb Musicplayer project which is a custom board and custom software. I used assembled a dev board with a DiscoveryF4 and MP3 decoder Arduino shield.

This test setup was my development platform for a custom firmware project. I tried to port the main features of a toddler music box to this concept board. I used the STM32F4 port ChibiOS to develop drivers for the MFRC522 RFID chip, WS2811 LED and VLSI 1053 mp3 decoder chip.

After finishing a basic software which played music files from SD card I started to use KiCad to layout a pcb. The manufactored pcb was delivered to me in the beginning of 2017.

It took some while to assemble the parts because there where some other projects on my list. In may 2017 a running version was finished.

Currently I am working again to get the software finished.
