    I gotta keep it real here. I know with the normal drama of handling power with typical CarPC's can vary quite a bit and makes for much chatter. I have had my Samsung tablet since the end of the summer and leave mine on all of the time. I don't have it connected to any power or ignition wiring. My battery charge lasts from 3 to even 5 days without needing to charge it. That's with internet music streaming and all the other data stuff like twitter, facebook, market updates, etc. All I do is have the brightness auto adjust plus I timeout the display and enable power saving mode. I turn off bluetooth, wifi, gps and only enable when needed. (Tasker app is your most bestest friend in the whole wide world

    The simplicity of powering is one of the many reasons why I went to the tablet and ditched my carpc build. So my answer to your question from my own personal experience (can't speak for others) I say simplify your design on power...and maybe even not worry too much about it.

    Ok, that's a good point. It does seem to go for days without needing a charge. I still need to power the converter though. So I guess I'll stick with the P O L i have and use it for that. Thanks man. I'm planning on getting that thing done and ready for install next week while I'm off. Maybe I can get it installed, even thought he rest of the system won't be anywhere near done. Lots to come that's for sure.

    I was thinking about it last night and I have to have a power source to the tablet. I have to have it for the HDMI to work! So I need a charger up front. So I guess I'm back to my original question. Can I run them both off the same POL or do I need one for both, or should I go with a bigger device?

    What type of adapters do these thing use? Can you simply use a USB car adapter? I have a Mi-Fi in the car with mini-usb connector. The Mi-Fi has its own battery, but i wanted to keep it on 24/7. It only lasts 4 hours on battery, So I bought a 5V 1amp USB car charger. So far the Mi-Fi has been on for almost 1 month.

    The tablet has a usb to 30pin connector, and the converter has a barrel connector to it an goes to a wall plug. Both are 5v after testing, and I'm not sure of the watts on it.

    I dont think its the watts you want to look for. Its the Amps. Say for example my Mi-Fi requires 500 mAmps at least to charge. So I paried it with a 1 amp charger. I took my numbers from the device of the wall plug itself, it should list it there.

    Just for reference, watts is a measure of power which is amps x volts so it is related and although more commonly rated in AC circuits, does apply to DC as well. If the voltage is a fixed number which in this case is 5v, and the current requirement is 500mA, then finding a supply that outputs 2.5w is the same thing as a device that is rated at 500mA. Just thought I would clarify this.

    Dang it, I forgot to update this forum. I've been on my other forums updating and not doing all the audio over here, so I forget to post the tablet portion. I'll catch everyone up right now!

    Ok another day in the books. Not nearly as much done as I thought I'd get, but I'm pretty pleased with the progress. I can see things coming together.

    First up I started Version 2 of the tablet pan. The more and more I look at this and think about it, the more and more complex it seems. But I'm gonna keep working at it. Here we go.



    If you will recall, I was going to use the docking station for this. After taping it up, and looking at it I decided not to do it that way. I decided I would just use the base part of it, and cut it in later. Thankfully I decided this after tape and not after glass or there'd be a version 3.








    Time for glass! ALl my materials, including my coffee! Let's go for it.




    Got some wax on it this time to help with the separation after drying.


    Then I started the glassing process!


    2 layers!
