Parital Teardown / Repair of Sony MDR-XB650BT

Welcome to another edition of I broke something, SO LETS FIX IT.

While on my daily adventures I had the misfortune of my headphones falling from my head and hitting the ground, the result of thus is the controller board for the headphones became loose due to a small piece of plastic breaking free, which technically meant that the controls didn't work and charging wasn't functioning.

So like any good tinkerer would do......it sat on my workbench for 3 months and then i eventually got to it during coffee time one morning this week.

So the teardown was actually fairly simple, the first step was to gently pull at the edge of the earcuff where it is glued to the headphones, when you see the ring of adhesive take a flat head screw driver being careful not to tear it, and pulling up the whole ring revealing the initial 3 screw holes. ( as shown in the below picture.

Screw holes are revealed after the earcuff is gently
removed from headphones.
First take out the three screws that hold down the actual speaker, there are two tiny gold wires that control the speaker so be careful not to tear them. (as that side won't work then)

Second remove the four screws that were under the speaker and partially hidden.
 Third step reach in gripping the edge of the housing to seperate it, again being careful for the wires attached.

In my case i had to reseat the board and put a piece of electrical tape under the volume down rocker button to be able to get my headphones working fully again.

Inside shot before electrical tape and placing back into place.
 After a little tape to fix the rocker button, the unit is fully functional after a little testing, put back together they are now fully functional and are my daily drivers again.
After shot when in place and electrical tape near center  to repair the rocker.
So remember people, never be afraid to take something apart that's already broken, as i had got this off a local used site already, no warranty was to be found, so nothing to be lost except some time.


Have fun out there people

PirateBox for portable public library/ or other offline resource sharing for AR games

For those who are unaware what a pirate box is, it is a...  " DIY anonymous offline file-sharing and communications system built with free software and inexpensive off-the-shelf hardware."   These little repurposed routers are lightweight systems which make a wifi network in their vecinity and offer web services such as chat and access to files / leaving files.  They can be left as a deaddrop in which they stay at a location and anyone in the area has access to them, Or there are ones people keep in their bag and are only available when they are near. They are a very unique diverge in the cloud based thinking that usually follows this day and age, Instead of trying to keep everything syncing and updated all the time, these ones are updated manually by the users and as such a more personal content and localized experience. The default setup leaves you with a pocket router with a usb stick coming out the side (i usually suggest 16-32gb at least if you're wanting...
