The SpaceBlaster is the ideal hackerspace portable speaker soundsystem. It's the competitor of the DeBASS and the DeCRASH.

Materials

  • 2*50 W digital amplifier board TPA3116D2 (two-channel)
  • C.H.I.P.
  • Arduino nano

Progress

20-11-2016

Stripped the main board of all transistors and other electronic components except the switches and potentiometers.

One tri-state switch has been connected, I will use two GPIO pins to detect in which state the switch (up, middle, down) is to save GPIO pins.

Possible layout of the ARM board, arduino and amplifier.

Wago's are used on the other side for the ground / power to avoid cable clutter mess :)

Cable mgmt:

  • Blue cable => potentiometer
  • Black => Ground
  • Red => 5V

Arduino nano will be used for digital gpio and analog input, data send over serial to the ARM board. Which will in software control bass, treble, switches for pause, play, stop.

future plans

  • Battery powered / charging integrated
  • Subwoofer? Currently the speakers miss bass
  • Jack in for phones or bluetooth
  • display now playing track
