Working on

This is a place where I would love to receive some input from the community ;)

Software

• ChibiOS/RT / RTX / NuttX ?
• Display driver / HAL
• Battery / power state handling
• USB / SD (have SD FATfs ect working)
• Loadable system like r0ket or something ;)
  • apps to handle background tasks
  • demo's animations and effects
  • Audio player(s) (+mp3 decoding (worked) +SIDplay2 (planned but should be easy))

Hardware

Stuff not yet (fully) functional or in planning stage

• Power system
  • Just 5V or different voltages needed?
  • LIPO
    • "Smart" charger system
• Audio AMP
  • 1W isn't enough!
• DMX512-A both as receiver and transmitter via some RS-485 transceiver chip
• Networking, preferably wireless

Is on Fire?	Definitely
