The World's Simplest Hack: iPod Party Amplifier

A speaker system for any mobile device.
No tools, parts or tinkering necessary.

Similar projects worth following
Instantly turn a cassette player into a power amplifier for (almost) any headphones device.

Just press the PLAY button from the cassette player, then place the headphone bud on the cassette player head. You may also want to press the cassette player PAUSE button, in order to spare the pinch roller.

Now, you have a power speakers system for your mobile device.
No tools or tinkering necessary.

    As Adam Fabio noticed, there might be a concern related to the "connected" portion of the contest. Thank you for pointing it out. My interpretation of the "connected" request was that the mobile device is connected to the boom-box, using the electromagnetic field generated by the ear bud. Indeed, this is an analog connection, not a digital one.

    That is why, a new video for the same idea will be uploaded, this time using a digital mobile phone connected to Internet.

    Some people may consider this hack too simple. Indeed, it's dead simple but effective, that is why I share the idea.

    There was a request to have at least 4 entries in the log. Since I don't remember the deadline for the 4 entries, I will add them, just in case.

    The iPod Party Amplifier was built, then tested:

    Pros:

    • It connects old and new technology.
    • Works as expected on Earth.
    • Reuse of an old stereo.

    Cons:

    • Might not work in outer space.

    Verdict:

    • Total success.

Great Hack, and it would have been more useful if I would have known this trick a few years ago.

this takes me back , i wish i saw this way back when disk-man was a new thing . back then i had to hack a old tape player head and cassette to make a adapter that can now be bought in dollar store.  but man i never thought to just jam a head phone rite in there .. brilliant hack !

Superb Hack!! Something like that never went through my mind, I'm dumbfounded!

The magnet in a headphone will attract to ferromagnetic stuff in the head, so "Planet Earth Gravitational Field" is not obligatory =). You made my day!

Yes, simplicity is the main claim here. That is why I consider this one much more elegant compared to my other projects posted on HaD like:

hey - who said a project has to be complicated to send you to space? Thanks for entering your party amp in The Hackaday Prize!
Don't forget about the connected portion of the contest - you might use an iPhone instead of an iPod.
Our community voting will be starting soon, so try to put a few updates up.

Thank you.
