I have an old Philips Portable Stereo at home and it gets no use with all the modern replacements and alternatives for hearing radio and music, the CD player in it also stopped working years ago.
I work in a metal fabricating workshop and music is nice to have, we are however a little short of the blue 220v sockets otherwise I would just rewire the plug, but this presents an opportunity as it has a battery compartment.
I could change the current 6x D cell battery option to a lithium battery option like 18650s. That way I could charge the cells at home and use the stereo in work with no plug.
As mentioned the CD player is also dead in it, and I would like Bluetooth ability for it (I also have some old phones that can act as music players just for this). There is also a tape player but I am not sure which is easier to mod in a Bluetooth module.
And ideas or comments on what or how to do this would be appreciated. I know there is a post from a user that did a nice one and @DeusQain demoed which I will also have a look at.
As you can see it is no super cool retro boombox, the workshop gets dusty so I don’t want anything super nice anyway.
The option is also available to maybe paint the shell of it just for shits and giggles while I am at it.
I am also interested in which of the battery techs would be best.
- Flat square lithium like from a battery bank,
- Lifepo? The iron ones just for safety but no idea what battery life is like.
- NiMh? But not sure if C or D cells are available or if it is a good idea, longest battery life is the goal.
- RC Car battery block.
- Simple Bluetooth drop in to make it a wireless speaker.
- RasPi headless to be an offline jukebox, attachments could be added for other functionality like Bluetooth.
-BOTH!? CD as the Pi Player and Tape as the Bluetooth?
