Portable speaker in a CD case!!

Step 5 Fix the speaker, switch and stereo adapter in place

Use a glue gun to fix the main components in place. Don't glue the battery though!! Leave the glue to dry up for 15 mins. Connect the 9V battery, ipod and then switch it on!

Now you can carry this portable speaker anywhere you like. You can even put your ipod inside the cd case when it is not in use!!

Enjoy~

I would recommend not putting the iPod inside the case, as the magnets from the speakers could mess with your iPod's memory! Just a thought.

Nah it won't... these days electronics almost aren't effected by magnets (excluding CRT monitors), here you don't have a tape to blank when you run a magnet by it :D. it's all just thousands and thousands of transistors (in chips of course well by that i mean , let's say you have a cpu in one of the older versions i remember there are about 73 mil. transistors and that cpu is from 2001 i think so....)

Just wanted to give you some updated numbers:

The Tegra 2 (used in many smartphones but is being supplanted by the Tegra 3) has 260 million transistors.

Most modern desktop CPU's have between 250 million and 1.2 billion transistors, while server CPU's can have up to 2.5 billion transistors.

Modern desktop GPU's can have up to 4 billion transistors.

Most people will never encounter an FPGA (a sort of reconfigurable CPU), but they can have just shy of 7 billion transistors.

A gigabyte of DRAM (the kind of ram in smartphones and PC's) has about 8 billion transistors.

A gigabyte of Flash memory has either 8 billion (SLC) or 4 billion (MLC) transistors.

It would take a horribly powerful magnet to mess with any of it, since they all off specific electrical signals at certain voltages which are incredibly difficult to generate by accident with a magnet. As you pointed out the magnets were a concern for certain magnetic storage technologies. Even then, while a floppy disk could be damaged by an errant magnet in the pocket, even modern magnetic hard drives require much more powerful magnets to destroy the data without physically touching the platters inside (hard drives actually have quite powerful magnets sitting right next to the platters which don't affect the data at all).

Simply put, it's not likely you'll be able to get your hands on a magnet powerful enough to hurt your smartphone, and you most certainly won't be able to get that magnet to fit in your pocket.

Yeah, the cpu i mentioned wasn't from 2001 but from 1991 or so lol.
About the hard drives, i've seen the magnets inside and they're really powerful but as you said they can't erase the data, to erase the data (and probably completely destroy it) it would take a magnet about as powerful as an MRI or something bigger.

There's always a way :) and most of the time it's fun as hell!
