My Pi will arrive next week, and I've also ordered a "HDMI+VGA+2AV Driver board+7inch 800*480 AT070TN92 V.5 Lcd with touch panel" from eBay after reading Andrei Istodorescu's blog post here:http://engineering-diy.blogspot.com/201 ... creen.html
This is what I bought on eBay: http://www.ebay.com/itm/HDMI-VGA-2AV-Dr ... 27ccad6b46
I'm a super beginner at this whole Raspberry Pi thing. I may want to mount the RPi w/ screen in my car or make a portable SNES system out of it. I'm not sure yet, as I have a lot of learning to do.
But first - how do I power the LCD/touch panel?
The eBay seller describes the power supply as needing 5~24V. That seems like a pretty large range. Later in the description, he says "Please connected ACC to 12V." Does the touch panel get power by being plugged into an RPi USB port? Can the LCD receive power the same way?
On that note, if I need to plug the touch panel into a USB port, and I will also need RPi USB ports for a bluetooth dongle, wifi dongle, and keyboard, then I will need a powered USB hub. Can this be powered by plugging it into both USB ports like some external hard drives do?
Obviously, I want this to be as compact as possible. What do you recommend for a low cost, low profile USB hub?
P.S. I ordered and received a Raspberry Pi enclosure, but I have nothing for the LCD or LCD controller board. What would you recommend for that?
I live in Oakland and work in San Francisco, so I have access to places like Noisebridge.net and Techshop.ws, but I'm a complete newb (read: no experience whatsoever) when it comes to 3D printing, creating plastic stuff, and dremeling. I do have limited soldering experience (just enough to know how to do it).
