OK, so a while ago i prototyped an invention of mine, the speaker-bag. My idea is hardly original and commercial alternatives exist, but essentially i was looking for a cheap quick portable music solution. (Skull-candy charge a bomb for theirs.)
Essentially my prototype was a rucksack fitted with 2 speakers (one sewn into each side-pocket), couple of 9V batteries and a small amp (stolen from disused computer speakers). The entire things was pretty-much held together with gaffatape and safety-pins. I just ran a line-in connected to an iPod for audio input. It worked nicely and was well received by my friends, who all fought over control of the music.
As you can see in the pic, it is an absolute monstrosity.
Gaffataped grill on side is a feeble attempt to waterproof it.
Now i am looking at making a more efficient less sketchy (plain crap) version. DJM and i have a nice amp kit built and it should be made soon.
Amp + Speakers + Battery + Bag = Speakerbag
And yes, the bag, pictured actually works.
I am interested to see if anyone else has made anything similar or is now inspired to do so. I have a few wild ideas about wirelessly linking multiple bags (think portable 5.1 surround system!) but i am constrained by budget.
Happy making.
