    Outstanding! If you build it (the Arduino thing), I will come! I will gladly pay you for that gismo. This summer i will be installing a Galaxy tab 3 8.0 with a Sony HU and would love to have the option to just hop in the truck and go.

    Please let me know if you decide to build those boards for people.

    And thanks for sharing.

    Here is a quick breakdown of the costs involved in building the Arduino. I got these parts from my local Radio Shack because I didn't want to wait for shipping so you might be able to do a little better if you're willing to wait for delivery.

    Arduino UNO board: $30

    Jumper Wire: $7
    http://www.radioshack.com/product/in...ductId=2103801

    IR LED: $3
    http://www.radioshack.com/product/in...5&locale=en_US

    I would recommend investing in a case for both security and appearance although it is not required for functionality. Here's one from Amazon for $12:
    http://www.amazon.com/Arduino-Enclos.../dp/B00HFSWC06

    So all told, it's about $50 in parts to essentially create a remote control for the HU that you can execute from Android.

    Let me mention another thing about the current state of my build. I have a Nexus 7 2013 whose stock kernel does not support OTG USB Host + Charging. You need OTG Host because the Arduino connects to the tablet via USB and you need to simultaneously keep the power flowing into the tablet since we won't have access to the tablet's charging port behind the dash. While there is a kernel for the N7-2013 called ElementalX by flar2 that does enable OTG USB Host + Charging, it's not the most stable thing in the world, and I can count on at least one random reboot per day. I can deal with that for a couple of months or so because the Timur rom that worked so well on the N7-2012 is being developed by Timur for the 2013 version. Here's some info on that:

    I can confirm that I was also able to get appmode started on the tablet, by using the remote controls and Lastmile's instructions. Awesome! Can't wait to see the arduino information. what IR blaster did you use? this opens up so many possibilities.

    Fantastic! I have about a month before it gets warm again so i have time to look for the best prices. As far as the "OTG USB Host + Charging" capability, i think i have that in the custom kernel i have installed on my Galaxy Tab3 8.0; i have a multimedia dock that i can have a thumb drive, keyboard, and HDMI plugged-in while still supplying power to the tablet - all at the same time.

    Thanks for the info.

    Just put the finishing touches on my Tasker profile so I thought I would make a video demonstration. Didn't want you guys to think I was all talk

    Here it is on YouTube: http://www.youtube.com/watch?v=FkVJh8rhYWUY

    What about the sketch? And how did you record the raw ir codes from the sony remote? Much appreciated.

    I attached the sketch for the Arduino.

    I used this IR receiver from Radio Shack with the Arduino to record and decode the Sony IR remote codes:

    http://www.radioshack.com/product/in...ductId=2049727

    The model number of the remote for the Sony 3100p deck is RM-X231. If the model number of the remote for the Sony 4100p desk is the same, then you wouldn't need to record any codes as all of them are in the sketch.

    Got all the hardware. just under 50 bucks like you said. I don't want to ask to many unnecessary questions so i will plug every thing up and import the .ino. One question i have is where to stick the legs from the LED but i think i should be able to see it once i open the sketch.

    Long leg of LED goes to pin 3. Short leg of LED goes to ground and I accomplished this by using one of the wires from the kit I linked to earlier. One end of the wire goes in the ground pin and the other end, along with the short leg of LED, are connected by a garden variety two-pin female jumper--the kind you might find in older PCs. I've attached a close up in case that helps.

    The sketch is based on the IRremote library by Ken Shirriff so you may have to download that before the sketch will compile in the Arduino IDE. Then you should be able to upload the sketch to the Arduino, open the UsbTerminal app on the Nexus (or use the Serial Monitor on your PC) and fire away! Also, in case it helps anybody, Radio Shack is offering $10 off a $30 purchase if you want to get your components from there:

    Hummm..I'm confused already (figures!) I don't understand how pressing a button on the terminal app keyboard a signal of some kind is transmitted to the Arduino?? I don't see any connection between the tablet and the Arduino?? I see the Arduino is connected to USB so is that where it's getting a signal from?

    I did see that the LED goes in pin 3 and ground. At least i didn't have to as that question.
