screen compatbility

royston02 over 12 years ago

I am planning of making a portable computer with raspberry pi. I found a touchscreen display for a olinuxio board. But since I am new to the electronics world, I don't know so much to reverse engineering, so if anyone out there can help me, so can you tell the steps?

    I found this screen. Can anyone give suggestions regarding it and RPI and how to make it run of 5V.

    Should be pretty easy, it uses composite which the Pi outputs, get a DC supply capable of 12V for the screen then get a regulator to give you 5V from the 12V for the Pi.  It's exactly like using the 3.5" screen Ben used on the Portable Pi project.  BTW, this one is cheaper

    Some of the screens work on 5V, but most require 12V.  You can use a boost converter to get 12V, or you can provide 12V and the use a linear regulator or a buck converter (switching regulator) to get 5V for you Pi.  Also, that screen you posted is not a touch screen.

    So what do you reckon about a touch monitor and make it run of 5V?

    I want the ideas before Dec 30.

    Any comments regarding it and RPI.
