1958 Turntable from the Black Forest - 1: Perpetuum Ebner Musical 1

Jan Cumps

I own a defunct turntable from the fifties...

 

I started the story with a lie. I don't own it. It's not mine. It happens to be in my mansion but it belongs to someone else.

It's a Perpetuum Ebner Musical 1. If you are into beautiful designed products, you'll like the looks:

And I'm going all medieval on that machine that's not mine. It is currently in non-working condition. It must have been in a non-working state for tens of years.

And I'm not making it any better:

At the moment it's more a doomed object than an enchanted one. I took the action picture above a few minutes ago. It's in a dire state of decomposition at the moment.

But I have wild plans

 

The plan

 

I'm going to fix it! And I'm going to enchant it straight into the 21st century.

I have good hopes on bringing it back to live (I couldn't wait for this challenge to start so I have been prototyping a fix). And then all options are open.

I've been thinking about making it a home audio wifi streamer. I'd like to use a Shazam-like service that recognizes the song that's playing.

I'd like to post stats on the cloud. I'd like it to be able to decode those satanic backwards played messages that were hot in the 70's Rock scene.

I'd like to ...

 

Failure is an option

 

Of all the things on the bucket list above, I have the skills to complete one: fixing it.

For all  the other ideas I don't have the skills. I don't know if the supplied parts are up to the job. I just don't know anything.

So you can find out together with me if this story has a happy end.

 

 

Side story: Perpetuum Ebner

 

The history of the Perpretuum-Ebner company from the German Black Forest reads like a fairy tale by itself.

It's a story of families breaking up, brothers starting a competing factory in the same village, deception, family raws and tactical marriages.

And its setting in the vast and mysterious Black Forest makes it even more daunting.


We'll try to unravel all secrets and conspiracies in this blog...

  • Using an embedded computer as a permanent Shazam-like service is really cool! :-)

    By the time I find my phone, and start shazam, the song I want to tag has usually ended, so I have often wondered why isn't there a 24/7 service running in my house (or in a bar) tagging/logging everying, and having a dedicated device for this is definetly better than killing your smartphone's battery.

    If you go for linux on the SAMA5D4, there is an opensource project for music fingerprinting that you could use and integrate with the rest of your software.

    Echoprint - Open source music identification

    Alternatively, you can run android on SAMA5D4 and actually use shazam or soundhound, but integration will have to be a hack :-)

    Good luck!
