[WIP] The Nook Color Backpack....

To avoid jacking Verygreens thread on usb host support, I am creating this thread for development of the Nook Color Backpack.

What is the Backpack, you ask?

The Backpack will be an open hardware based addon similar in style to the sliders used on Compaq(HP) iPaqs. It will be self contained in that it will carry its own battery source for powering USB peripherals and also a few built in goodies such as a camera module, stereo speakers(possibly amplified), and possibly a GPS module.

This thread is to help others who may want to build a similar device and to accept input from the community on its design. PLEASE, refrain from any flame wars or other similar postings.

Feel free to post with suggestions, comments or even criticism(as long as it is constructive).

Sparkfun.com sells a bunch of stuff that would make for a good prototype:

5V 600mA boost converter and LiIon charger (w/ microusb charging port):

2Ah single LiPo cell:
http://www.sparkfun.com/products/8483

microUSB plug - right angle breakout:
http://www.sparkfun.com/products/10031

USB A socket:
http://www.sparkfun.com/products/9011

If you were planning to use a hub you'd need a more capable boost converter or go with 2 LiPo cells in series and step-down. For a proof-of-concept I think you can get pretty far with these parts.

Thanks pokey. I'll check into those. As far as the plug, I'm currently looking at buying and modifying a stock cable...to retain stock charging from a high amp source. Externally I think I will be going with a standard female USB A port for power in/stock USB connectivity.
The hub I've chosen so far is a cheapo Targus unpowered. Very easy to mod into what will be required.


Really need to get on a rough draft drawing of the general layout. I work 12 hours a day in construction. Ill try hard to squeeze spare time in for this and pics of the little I have done so far this week.

solar panel, 1.8" hard drive, flash card reader, speakers and 3g card are some things I think might also be cool in something like this.

I am digging this idea. Can't wait to see some progress on this. If the speakers were bt then you could limit the wires some. Space for a 1/8 inch hdd would be nice because you could just use a cf card if you desired. Could really make the nook into a sort of laptop device if done right. Really can't wait to see this. Also check this out. Found it in another thread. May want to add a holder for it into the design somehow. http://www.amazon.com/ProMini-Wirele...ref=pd_sim_e_1
