Felix Huber has created a new piece of hardware called the Boxmaster which provides a manager for mobile music boxes and takes care of all the filter-, adjustment- and controltasks of your selfmade speaker.
Check out the demonstration video below to learn more about the Boxmaster version 1.0 which is taken to Kickstarter this week to raise the €5,000 Felix requires to make the jump into production.
No matter, if you wanna build a wodden speaker or a musicbox in an empty crate of beer – take the boxmaster and add your speakers, power supply and amplifier to start through – you can adjust everything while building your box and you can skip calculating or tuning of your musicbox!
