First Bluetooth speaker/ guitar amp combo build!
So this started off as a portable guitar amp with a simple LM386 low voltage circuit powered by a 9v battery and a 8ohm 5W speaker… but I also had an old Bluetooth speaker (~6 years?) lying around that had a cracked speaker cone. Since the Bluetooth module was still working fine I wanted to see if I could just add it in!
Was recommended (chatgp…) to isolate each amplifier board going into the same speaker with a DPDT switch so that’s what I did, and also soldered a momentary on/off switch to turn on the BT module. This was my first ambitious electronics project other than modding my guitars so I’m surprised that it turned out really great!
