Hi nFinity,

Looks very nice, like it a lot.

Where did you buy your power supply from? I would like to switch to that one.

How is your DAC performing? I bought the DragonFly because of its low profile and good review on amazon. The only difference I see between using the DAC as oppose to the 3.5mm jack, is that the DAC performs better at high volume. With the 3.5mm jack, the sound would distort when you are approaching very high volume.

The sound coming from the DAC is pretty darn good though...

Also, I cannot get my notifications sound to go through the DAC correctly. When I have a notification sound, like incoming email, it would play through the tablet speakers and DAC at the same time and sound very distorted. I have not figure out a solution yet, so I just muted my notification sound all together. I think this is a samsung issue...

I also damaged my first LAVA... The micro-usb to micro-usb cable that connects into the tablet is unique and not interchangeable. I tried to replace it, because I wanted a right angled one, and when I plugged it into the tablet and applied power, it damaged the LAVA.

I am using the Samsung Galaxy Tab A 10.1 inch running android 6.0, I rooted it, and using Automate from the playstore for power management.

I setup automate to do these things when it detects power ( Turn ON car):

1- Make sure all wireless are turned ON (GPS, WIFI, BLUETOOTH), if not TURN it ON.

2- Set the VOL to 20%.

2- If it is between 8AM and 7PM, set the brightness to 85% (DAY), if not set it to 35% (NIGHT)

3- Speak the word (Welcome), this is just so I have an audible alarm to tell me Automate is working properly.

When I turn off the car, AUTOMATE will speak (STANDBY), and lock the tablet. If within 30 min I do not turn the car back on, then it will enable AIRPLANE Mode to save even more juice and speak the work (Goodbye).

One thing I did not like about the samsung tablet is it is a fingerprint magnet, also the screen is very shiny; without a protective film, you can see fingerprints all over the screen. So I bought this screen protector https://www.amazon.com/gp/product/B01HD2AX3Q/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 , it is pretty good, also helps with the glare, and your fingers slides very easily without leaving any fingerprints.

For the volume knob, I bought these:

and

The volume knob works pretty well, I installed it right next to my armrest, so it is easily accessible along with my subwoofer control.

I also bought this Bluetooth wireless control which is attached to my steering wheel:

For FM Radio, I am using this:

https://www.amazon.com/gp/product/B01GDN1T4S/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

My car comes with a powered fm antenna, I built an adapter to hook up to the antenna, but the reception is not as good as my original radio. Also the radio app in the playstore are not as good as the ones in the chinese android head unit. I tried SDR touch and Wavesink. Wavesink seems to be better, but the UI is lacking from a user friendly perspective.

Right now, I am just using IHeart Radio and other streaming radio to listen to the radio.

I bought this for my backup camera.

https://www.amazon.com/gp/product/B00VQLS09K/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

This will allow two USB devices to be connected when it detect a turn ON voltage at 3.9V.

So when I go into reverse, I have 12V that will trigger the USB control and will connect the Easycap USB to my OTG, then the backup image will come ON instantly.

Another way to do it if you do not want to use the USB control, is to use the watchdog timer within the EASYCAP app. This will listen to a camera signal, and when it sees it, will open the app. But this is not instant ON, as it takes about 1-2sec before the backup camera image shows up when you go into reverse.

I am also using this as a dashcam, picture comes on beautiful, and I can see it live and record, no issues so far:

This one works pretty well with any USB camera. There are lots of dashcam app in the playstore you can use also.

I am using this to connect to my headrest monitors:

Works perfect, I can mirror my screen to my headrest monitor through HDMI WIDI
