Fixing A Tablet…

One of my co-workers gave me his Samsung Galaxy Tab 4 to fix.  Apparently, something went bad with the USB connector, and his kid was very persistent with trying to get the charging cable into it, and completely mangled the connector.  Then he tried to fix it too, which made things worse… including chewing up the outer frame.  He ordered a replacement USB connector and asked if I could fix it.  It sounded like a fun project so.. sure!

He had already popped the back off at some point, so I just popped it back off again.  The USB port had to be desoldered from the board.  Little did I know that it also was glued down.  That made it a bit difficult to remove from the board

With a lot of extra solder, and some leverage with the tweezers, I did manage to get it off.  Some work with the vacuum pump desolderer, some desoldering braid, and cleanup with rubbing alcohol and the mainboard was ready for the replacement part.  (Sharpie for scale)

Getting it lined up so that all of the pads matched up and that the connector’s opening would line up with the case was a little bit tricky.  I soldered this one on with too-large of a tip by doing the “flooding the pads” method. Then excess solder was removed with some braid.

Before I fully reassembled it, I tried out the jack, and it worked! I filed down and smoothed out the edge to remove any broken frame bits, to fix the damage done the first time it was opened, and powered it on.

Pirate Box, Aaarrr!!!

Finally a project I finished. I made a Pirate Box. Pirate Box is a Wi-Fi device that people can connect to and share files anonymously because it isn’t connected to the Internet.

Started with a Raspberry Pi B+, Eleduino case, 8 GB microSD card, 32 GB memory stick and a TP-Link TL-WN722N USB Wireless Adapter.




This is what it looks like completed.



When you connect with Wi-FI to “Pirate Box – Share Freely” it will show the following screen with a chat program and flie upload. (Looking to change the SSID in the future.)

This is the message board.

And the files that are uploaded to be shared.

This would be prefect to use to exchange encryption keys at BSidesRoc or have the presenters post their papers to share with the public.
