Bluetooth 5w speaker

This is a first test and work in progress for a rechargeable Bluetooth speaker with the ability to be added / hung from a kids bike carrier for bike rides and competing in Parkrun.

Note: all components were glued inside after being wired outside. Might change design for easier access and work-ability as some areas are tight.

Parts used:

- 18650 battery and holder
