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.
The best way to test it, and the best way to go a bit insane is to get a chorus of Talking Ginger and other talking animals going… They were repeating each other, degrading the sound more and more with each repetition… We were pretty punchy at the end of the evening…

We’re still working through exactly what will be presented on Saturday for Arduino Day, but here’s a rough idea… We can always adjust content based on the attending audience… And if more people show up in the afternoon or evening, we can always run through things again. We’re going to play this a lot by-ear.
More about Arduino Day can be found here…
We will be running an Arduino project challenge contest! Using an Arduino (or related micro), along with any resources and tools in the Interlock space, and/or materials you bring yourself, what cool thing can you build? Some old hardware (printers, scanners, misc parts) will be available to take apart… Judging will happen at 9:30, points will be awarded for usefulness, niftiness, artistic quality, and technical depth… The winner(s) will get something, to be determined. 😉
Throughout the day, we’ll have the doors open for all who want to visit and participate, or just check us and our space out. We’ll be around all day to help you with your Arduino project, or get help from you on our projects! 😉
10:00 am – Doors open, Coffee will be available, get settled in, get to know each other. Project workshop time as well (throughout the day)
11:00 am – Intro to Arduino – What it is, how to use it, some basic interfacing with buttons and lights.
Noon – Lunch! Sub sandwiches and beverages will be available.
1:00 pm – Project Circus – show off your project. casual presentations.
2:00 pm – Arduino Communications – How to get your computer to talk with the Ardy, and get them to talk with devices.
3:00 pm – Analog interfacing with Alex – how to work with other kinds of peripherals
4:00 pm – Project Circus
5:00 pm – Dinner! Pizza and beverages will be available.
6:00 pm – Workshop Time (or TBD)
7:00 pm – Workshop Time (or TBD)
8:00 pm – Workshop Time (or TBD)
9:00 pm – Project Challenge voting! (at 9:30)
10:00 pm – End of the event. We’ll probably stick around for a while anyway.
You can RSVP over on the Meetup page for this event…
