Kind of device hacking

I found this at a flee market. Actually I was looking for a transistor era grammophone for my project, but thought this will do. It has obviously been ripped off all the valuable parts for another grammophone worth saving. So this one clearly has run out of hope.


The grammophone will have a new future as a 3D scanner!
There's no mechanics under the turntable, not even an axis, let alone any bearings. I'm going to build a 3D printed large bearing with 8 steel balls. A stepper motor from below will rotate a large cogwheel glued onto the turntable. The tonearm will have a holder for a smartphone. The holder will be designed so that the speaker of the phone will direct the sound into the tonearm, which leads the sound further to the sound horn.
This is more of a fun project. Nowadays you don't really need a 3D scanner, when a simple smartphone app does the job. The advantage with a 3D scanner is still that you can let the machine do the job in 15 or 20 minutes instead of tying yourself to the photo shooting for that time.

That’s a gramophone

It used neither transistors nor tubes, as it was a purely mechanical device operating without electronic amplification.

You were probably looking for à turntable?

Although the gramophone’s horn would give a nice touch to your 3D scanner :slight_smile: (but may be come in the way)

Yes, I guess that's the corret term for the transistor (or tube) era equivalent.
Turntable is in Swedish skivspelare, but the word grammofon was used equally.

intersting - I learnt something (I'm trying to learn some Swedish)

All discs or records, whether they were 33, 45 or 78 RPM, LP or EP or singles or whatever, were called grammofonskivor. The CD ended the use of the word grammofon for good. Then again, skivspelare was still used parallel to CD-spelare.

Then again, I live in Finland, where the Swedish is more conservative.

I was told that mastering some Swedish would get me going in the 3 countries. Is that so ?

Yes. If you know Swedish, you do fine in Sweden, Finland and Norway. The Danish will understand you, but you won't understand them.
This year, Sweden has the first song in Swedish in Eurovision Song Contest since 1998. By a band from Finland!

I was in Sweden a couple weeks ago - heard indeed about the Bara Bada Bastu and the stronger accent (still beyond my skills besides the Bastu :slight_smile: )
