Introduction: 70 Years Old German BLUETOOTH Speaker

Picture of 70 Years Old German BLUETOOTH Speaker

We like old stuff.

It is not only because of the impressive quality, it is also because of the feelings, the memories connected with them and the thoughts coming with it. Ok yes, we are a bit nostalgic, but who cares? ;)

In our times, we also produce much too much waste, so we try to break down the most of the things before we throw them away. Planned obsolescence is definitely one of the negative side effects of the age of consumption. Often, you can use a lot of these parts again, for projects you don`t know yet.

We found this ancient speaker (maybe around the time of WW2!!) behind old stored firewood. It was really dirty and as we opened it, the cables looked shockingly bad. We didn`t even know what some parts are used for but the speaker itself was in a pretty good shape. So we decided to give it a new purpose and added Bluetooth. Now, we are able to control it with our smartphone. Don`t be afraid. It is very easy and you can do it very quickly on your own with any kind of speaker.

Step 1: Materials

Step 2: Cleaning

Clean your old speaker as good as you can.

You want that it looks good, so give your best.

Step 3: Use Black Tea to Enhance the Wood Color

If the speaker is a wooden one and looks really bleached out then follow this instructions.

Brew some very strong black tea and rub with the mix over the furniture. Wait until it is dry. Now the colour should pop out again.

Step 4: Add Bluetooth

I know that it is possible to build an own circuit, but in our opinion it is not always necessary to reinvent the wheel. So, we bought this cheap Bluetooth amplifier from China and connected it to our cables. That isn`t really a challenge.

Connect it with your power supply and look
whether it works.

Enjoy and think about what your ancients might have heard on this speaker.

oh verdammt! diese autokorrektur! schreibt alles falsch! Oben sollte es ...ARDUINO... heißen, und weiter unten ...habt Ihr...! Sorry das Handy schreibt manchmal Mist!

Team Z (author)db9pz2015-10-23

kein Problem =)

Hallo ihr beiden, ich denke ich kann Deutsch mit euch schreiben, da ihr im Instuctable für die DSLR ein Aruono Sketch in Deutsch geschrieben habt! seit ihr mal auf die IDE gekommen den LSP mal mit einem Ohm-Meter (Vielfach-Mess Instrument o.ä.) durch zu messen? So wie das aus sieht ist das ein alter Lautsprecher einer Kabel gebundenen Duchsage Einrichtung wie sie in Behörden oder auch Schulen früher gebraucht wurde. War da noch ein "Trafo" dabei? (korrekt hier ein "Überträger") Hat der LSP dann annähernd die Impedanz die er für euren Verstärker haben soll? Sonst killt Ohr über lang oder kurz entweder den LSP oder den Verstärker. NUR ALS HINWEIS ZU VERSTEHEN, KEINE KRITIK!

Team Z (author)db9pz2015-10-22

Hey danke für deinen Hinweis. Auch Kritik ist bei uns gerne gesehen, denn nur so kann man sich verbessern =)

Ja es war noch so etwa ähnliches mit verbaut, uns war die Funktionsweise aber nicht 100% klar und deshalb haben wir ihn ausgebaut. (Es gab soweit ich mich erinnere 4 verschiedene Einstellungsstufen)

Überraschenderweise reguliert der Amplifier dies automatisch. Hatten am Anfang auch bedenken, dass wir ihn damit schießen würden, aber funktioniert bis jetzt ohne Probleme.

Interesting idea. Could also be used to pipe in sound to old radios.

Team Z (author)mr electro2015-10-21

yeah, you can use this with almost every speaker =)
