After submitting the circuit decided to blow, this due to the step-up module.
As the Printed Circuit Board blew several times after several attempts. I went to the School of Engineering and Technology to see if I could require some assistance with the circuit.
The list of electronics changed slightly.
The speaker enclosure now contains:
- Amplifier and Bluetooth Board
- DC Plug Adapter
- Rechargeable Batteries
- On/Off Button
- In-line fuses
- Positive and Negative Wire
- Heat Shrink Tubing
- Nuts and Bolts
I decided to go for a preventative measure which where the in-line fuses these are to protect the batteries and the Amplifier and Bluetooth Board which would be more cost effective that constantly changing these items on a regular bases.
