Stopped: TV Soundbar
Common TV Soundbars are very expensive or really bad. This gives a niche for DIY. To develop the electronics for a solution with digital input there is know how needed I don't have. To sad :-( What about cooperating?
Common TV Soundbars are very expensive or really bad (because of bad speakers). This gives a niche for DIY.

What about cooperating?
What it should have:
A digital input of audio signals via HDMI CEC. This can control the volume of the connected electronic circuit (audio signal or amplifier) so only the remote control of the TV is necessary for daily use.
After Interfacing HDMI and extracting the signals a microcontroller should generate digital and/or analog audiosignals and a switch signal with which a connexted audio amplifier can be schwitch on and off.
The microcontroller should have at least be able to set treble and bass (tone control). Its values should be stored in EEPROM.Â
Maybe a simple Raspberry Pi as hardware base would be a good idea.
A dedicated remote control input is just an option but not necessary.
With this hardware it is easy to add a (stereo) audio amp and the personal preferred speakers to get really good sound at moderate cost.
What do you think?
