good 'ol times (der portable vintage wave radio killer)
musicbox for portable audio players
Ich bin zu faul es zu übersetzen, wahrscheinlich verstehen ja die meisten hier genug Englisch...
As an audiofreak, of course I needed a possibility to carry around my music for a walk out in the woods and just to be cool :)
I didn't want to spend a lot of bucks on some dubious boombox or ghettoblaster (what these were called back in the eighties and nineties).
So here is what I made:
I sewed some thin wood sheets lying around in the cellar and built a cabinet approx. 45*30*16cm. Inside the box I packed the Dynavox DA-30 digital amplifier with tripath chip (which is a descendant of the famous Sonic Impact 5066). A 12V sealed lead gel battery is used as a power supply for the amp. I drilled out a single hole 20mm in diameter (using a Forstner bit) on the front of the box for the volume knob of the Dynavox, which thankfully is also the on/off switch. This looks quite nice, indeed. On the sides I installed Grundig 7050 fullrange speakers from the 1960s. The lid is connected via two hinges I glued on the box using mounting adhesive. This is how the thing looks like:

Finish was done with two layers pine wood glaze. Looks quite oldskool ;) Around the corners I glued some wooden reinforcements. Not to forget: I added a grundig logo from an old musicbox in the left upper corner, and a carrying handle on the backside.
You can connect your mp3/audio player, iPhone, whatever... to the box. I am using one of my Archos mp3 players.

Inside view. You can see the Grundigs, which I installed from the inside, to protect the membranes. Instead of grilles I drilled holes on the sides of the box (which was quite some annoying work). Additionally there is a layer of black acoustic textile. Internal cabling was all done in pure silver wire Cryo Reference xxxl 4, NONO, just joking :) ...I used bell wire!
My daughter says "it's the most freaking thing you ever built"
Feel free to copy the design for non-commercial use :)
Future add-ons
When I find the time I might add:
solar module on the top to be environment friendly and even more independent
external speaker connectors with switch
2nd audio in with switch
screen?
beer holder?
