After cleaning and drying it, I decided to see what was inside.  I never took things apart as a kid because a) I took good care of things so they didn&#8217;t break, and b) if I couldn&#8217;t get it working again, I wouldn&#8217;t get a new one, so I didn&#8217;t risk it.  First time for everything!<\/p>\n<p>So here&#8217;s my photo documentary about taking my iPod Nano apart.  I have no great electrical skills so I didn&#8217;t bother trying to fix it; I just wanted to see how it was put together and what was inside.<\/p>\n<p>[DISCLAIMER: The thumbnails were automatically generated by WordPress and therefore not always centered or cropped the way I would like.

There are clips all around the inside so don&#8217;t be afraid to use some force.  The port is a good place to start.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/03_pryingapart.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-242\" title=\"03_pryingapart\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/03_pryingapart-150x150.jpg\" alt=\"Prying cover apart\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here are the two halves once you take it apart.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/04_coveroff.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-243\" title=\"04_coveroff\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/04_coveroff-150x150.jpg\" alt=\"Inside halves\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>There are two small screws on the lower part holding the circuit board down.  When you remove them, you can lift up the bottom half of the circuit board and get some leverage to flip the battery out.  It&#8217;s still attached by wires but it can be moved around.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/05_flashdiskwarnings.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-244\" title=\"05_batterywarnings\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/05_flashdiskwarnings-150x150.jpg\" alt=\"Warnings on underside of battery\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>With the battery out of the way, you can slide the circuit board down and out of the clips holding it in place at the top.  I found out later that these clips are incorporated into the screen piece.  Under that is a sticker on the back of the monitor &#8211; one side is reflective and the other has a serial number.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/06_screenbacksticker.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-245\" title=\"06_screenbacksticker\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/06_screenbacksticker-150x150.jpg\" alt=\"Screen back sticker\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>The screen is attached to the front cover piece with adhesive, so you can just pry it out.  It is connected to the circuit board by a fat orange wire strip.  Everything is still very connected at this point.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/07_frontviewofparts.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-246\" title=\"07_frontviewofparts\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/07_frontviewofparts-150x150.jpg\" alt=\"Front View of Parts\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here&#8217;s a closer view of the additional circuits underneath the screen.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/08_chipsunderscreen.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-247\" title=\"08_chipsunderscreen\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/08_chipsunderscreen-150x150.jpg\" alt=\"Chips under screen\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here&#8217;s another look, including the 2GB flash memory chip (on the skinny part of the board below the orange monitor wires).  At this point, everything is still attached to the circuit board:  the front cover by the clickwheel wires, the battery by its power wires, and the screen by its wide orange wires.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/09_underfrontcover.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-248\" title=\"09_underfrontcover\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/09_underfrontcover-150x150.jpg\" alt=\"Under front cover\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here&#8217;s a closer view of the screen&#8230;<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/10_screen.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-249\" title=\"10_screen\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/10_screen-150x150.jpg\" alt=\"Screen\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>And the back of the front cover where the screen was pried from.  You can see the holes for the button click points.  The four black spots (N, E, S, and W) are for the click points on the outside ring, and the two white spots between E and W are for the middle button.  Yep, two click points for the one middle button.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/11_backsidefrontcover.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-250\" title=\"11_backsidefrontcover\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/11_backsidefrontcover-150x150.jpg\" alt=\"Backside of front cover\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Underneath that metal plate is the clickwheel.  That piece was also attached with a strong adhesive, and it is very flush with the plastic.  This was the hardest piece to remove besides initially opening the cover.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/12_removedclickwheel.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-251\" title=\"12_removedclickwheel\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/12_removedclickwheel-150x150.jpg\" alt=\"Removed clickwheel\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here&#8217;s the underside of the clickwheel &#8211; fat orange wires just like on the screen.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/13_clickwheelback.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-252\" title=\"13_clickwheelback\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/13_clickwheelback-150x150.jpg\" alt=\"Backside of clickwheel\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>The clickwheel wires are (again) attached with adhesive to the plastic cover.  Take off the orange wires and the white button just falls out.<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/14_clickwheelparts.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-253\" title=\"14_clickwheelparts\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/14_clickwheelparts-150x150.jpg\" alt=\"Clickwheel parts\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Here&#8217;s a final view of all the parts:<\/p>\n<p><a href=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/15_finalparts.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-239\" title=\"15_finalparts\" src=\"http:\/\/www.pchristensen.com\/blog\/wp-content\/uploads\/2008\/05\/15_finalparts-150x150.jpg\" alt=\"Final view of parts\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p><strong>Final Observations<\/strong><\/p>\n<p>It is pretty impressive how tightly everything is packed (I think one of the new Shuffles would be even more interesting).  There are lots of places where the shape and position of one piece helps secure another piece.  Even on the inside it&#8217;s clever engineering.  Also (this might be a dumb observation but like I said, I haven&#8217;t taken many things apart), I was surprised by how many things were held in place by adhesives instead of screws or some mechanical means.  It makes sense in something this small but I wonder how common that is in larger pieces of electronics.  All in all it was a fun project, but I hope not to have a similar opportunity again anytime soon ;-).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve recently come into possession of a damaged, non-functioning iPod Nano (Public Service Announcement: be careful how you hold your iPod when operating a urinal) that gave its body to science.
