As there have been successful tries to use Mattzobricks with the SBrick and now with Buwizz2, I wondered if there has been an attempt to integrate Blunami from Soundtraxx.
One incredible improvement over the existing solutions is that this controller provides sound. Although predominantly US models, it already has a massive database for different train sounds. As far as I understand, these controllers also use Bluetooth. I could not find a rocrail integration, which might be due to my search skills.
I have successfully installed the MTC4PFmini and included advanced LED control. I also use steam generators for LEGO bricks with some locos. Compared to professional non-LEGO model trains, the only thing I miss is the sounds.
