Bluetooth receiver with speakers
Posted: Mon Oct 26, 2020 1:12 pm
Hi all. I am very new to esp32.
I only worked with raspberries before, where pretty much everything was already done, documented and a tutorial uploaded to youtube.
After some time of googleing i found the esp32, which should be very well suited for my project requirements. I hope I can request help in this forum and get your guys input.
I want to restorate an old radio ("Röhrenempfänger") from Eumig (which looks like this: https://www.radiomuseum.org/r/eumig_eumagnus_383u.html)
I salvaged the empty shell (50x33x22cm) for this radio on a flea market and want to add two speakers (up to 20x20cm) and a subwoofer. The sound quality should be very decent, because I plan to use this radio a lot. If you have suggestion for good speakers in this size please let me know.
I want to connect my phone via Bluetooth to play music from Spotify.
The volume should also be controllable on the radio. A second rotary control to go to next or previous song would be really nice to have.
I have no need for this to be portable, so a 12V DC supply would be sufficient.
Adding an amplifier tube (like this: https://www.aliexpress.com/item/1005001488549403.html) for visual aesthetic only in the center would be very cool because this were the identity of those old radios. Is this possible and if yes, which PINs need to be addressed?
Any help would be very appreciated.
