[Nexus 7 General] turbobaggins:
Hey everyone. I am about to start installing a Nexus 7 in my 2003 Ford Mustang.

Goals:

Easy removal of unit.

-Temperature is near zero at some points in winter and over 100 in summer.

-Use of hard case to hold unit in place, possibly mounted by a small variation in the shape of my stock stereo surround and the use of strong magnets. If that does not work, permanently mounting hard case to stereo bezel

-Use of double din space behind the mounted nexus for the EQ and my boost controller to go.

-Fabrication of pogo pin system for easy connection/disconnection, allowing for charging and usb hub support while nexus is in its "cradle". Adapter for micro usb > pogo, to help reduce wear on the micro usb port of the nexus.

Stock look

-if I don't like the look then I will try and fabricate something to surround the nexus while it is mounted.

-modifying the stereo bezel is not an issue, they are cheap to replace

- Clean wiring and functional placement of components

Better than stock function and sound

-USB sound card

-manual volume control (making a volume knob that controls EQ that is accessible)

- Radio (I don't use it but its a selling feature if I have to sell the car)

-easy access to peripherals in case something needs to be adjusted or replaced

-no alternator whine or sub standard sound just because it is a tablet, in fact it must be better than what I have now

-GPS!!!

-WARDRIVING!! (I do not have a smart phone, so internet will come from WIFI for now)

Less than $500 (cost of a high end stereo with far less capability, also less than a decent carputer setup)

Future plans

- possible megasquirt engine management that is tied into the device so that I do not have to lug my laptop around when I tune my car (it sucks and is dangerous to try and use windows while driving fast), plug into 4 different USB devices, and deal with crappy UI's

- at the very least, integration of all of the data my tuning components are giving without using a laptop. OBD II may or may not solve this.

Components I have purchased so far:

MISC (bondo or epoxy, wire, etc)

While there are a few well documented car installs, I think there is always room for another. The main thing that I hope to bring to the table is (hopefully) creating a reproducible way to make a quick disconnect connector from the pogo. I checked on patents, and there is one already, so even if I felt like it was worth it, I probably couldn't mass produce them. So now the technique will be in the public domain (hopefully). The adapter should work for any micro usb device. It could be adapted for different connectors, possibly even using the Nexus 10 connector to add audio to the dock. You could also use 2 of the 4 pogo connectors, 1 for audio and 1 for usb. Anyway.

I am waiting for stuff to arrive. I will update once it does.
