button control prototype
I really just wanted to have a working jukebox, so I built this.
features
- Switches
- Combined Volume and Track Select Sunctions
- 9v rechargable Lipo Battery
notes
Due to the 3.7v Lithium Ion battery being boosted to 9v and then immediately bucked down to 5v... The battery life is only 1.5-3 hours. And the mp3 module I used has a terrible stand-by current draw.
