First of all, excellent tutorials on the PiTFT 3.5" setup. Was able to get everything working properly in short order.
My issue is that I would like to separate the PiTFT (https://www.adafruit.com/products/2097) from the Pi B+. Would a simple extension ribbon work or is there a better solution?
A little background on the project if it will help... I want to mount the Pi B+ inside the wall and have the screen be mounted to the wall surface (think switch-plate size). The B+ will fully fit inside of a dremel'd out single gang old work box (the 20in^3 blue plastic ones - http://www.homedepot.com/p/Carlon-1-Gan ... /202077323). That fit, however, mounts the Pi sideways inside of the box. Therefore, I need to decouple the Pi positioning from the screen's positioning completely.
I have also considered surface-mounting it using a deep surface mount box (http://www.homedepot.com/p/Legrand-Wire ... /202518488), but it still would need to separate the screen and pi to ensure no releasing of the magic smoke.
Of course, I'm sure a 3D printer could create a custom old-work box for the Pi & screen together which would solve the issue. However, learning the software for that is beyond my project scope atm... :-)
Thanks in advance for your help with this!

Sure, an extension ribbon cable will work just fine for this.

Re: Separate PiTFT 3.5 & B+
I've used an extension cable to move my PiTFT 2.8" off of the original version 1.0 of model B, where I plug the 28 pin cable into the second set of pins that is a pass through to allow you to hook up other gadgets. I would imagine it would work for the 3.5" and B+, though you might need the 40-28 pin cable.
To add my real time clock, I plug in another extension cable into the slot that normally you would plug into the Pi, and it worked. I was even able to power the PI by feeding 5v to the 5v/ground pins. However, as noted elsewhere, the i2c bus goes hay wire, once I bring up PyGame to run the camera app on the PiTFT, but it does work to set the system time, before I bring up the PiTFT.

michaelmeissner is right - you may need a 26 to 40 pin cable. You may not be able to plug a 26-pin connector into the 40-pin header on the Pi.

Thanks, everyone! Will check that out right now.
