The main problem with linux that there is no good navigation software for linux. I've tried Navit, but.... actually it's not as good as for example Waze.
Also in linux you'll have to use some kind of shell with icons, widgets, etc. But in Android it's already there Smile

Good news the pine64 hi-fi audio board it's on the go!
Check the external DAC thread for more details (link in the first post.)
This means that we have one thing less to care about

What I would like is to use ignition as power on/off. In most cars behind the head unit there is a battery constant (yellow) and an ignition wire (red). Want to prevent the pine64 to drain the car battery when the ignition is not on (and don't want to be forced to use an external physical button).
So ideally I would wire up the pine64 directly with the car battery (yellow) (with a 12v to 5v converter) so it wont just shut down when you turn off ignition and internal clock wont reset. Then somehow use the ignition wire (red) to power on/off the device, anyone have suggestions on how to do this?

ya my plan its quite the same but i'm going to use a USB charger to power the board and filter it with some caps! so i avoid noise Big Grin
to turn on/off the Display i'm going to use a service app that monitors the Accessory cable via a relay triggered to ground using one GPIO so
if is Undefined-state - OFF
if is LOW-State-On
and i'm going to use my nexus 7 battery to power the pine while is not powered by the car Smile

in this way i avoid the battery drain Big Grin

this is something what you had on mind.?

a USB charger is a 12V to 5V converter, isn't it?

Using it's own battery was an alternative I was thinking of. Then you can monitor charging state instead, wake up when charging starts, go to sleep mode when charging stops. But how long would, lets say nexus 7's 4,325 mAh battery last in sleep mode for the pine64? What happens if you leave the car for a week and it dies, how can you then turn on the pine64 with the ignition?

Ya u can turn it on with the ignition
In my case i will start it with the accessory automatically cuz it's like connect the usb cable to power it up
And if u leave your car for a week and the battery(of the pine64) dies
This will charge it as soon as u switch the accessory
Its going to take a while but eventually will charge

So how will the power up and down really work? You mentioned relays with the GOIO pins for turning the screen on and off, would it also work to power it on when battery is dead and device is off?... Would it be possible to instead edit software to check for charging state, in kernel, bootloader or some other software somehow and power up the device when charging starts.

It's been done with the nexus 7 this way; http://forum.xda-developers.com/showpost...stcount=69
Wonder if it could be done with the pine64's bootloader or kernel.

Ya it can be done by software too but we need to add it to the kernel that feature (no a big deal I expect)
But I was giving you an idea of a way that it can be done
By monitoring the accessory
Or by software by monitoring charging state
When I receive my playbox I'll keep working on that kernel Implementation
And the the hole project

Do you have any ideas or suggestions for features for this project?
Please post them.
