Have a question about the Next-Gen BeagleBone? Ask it here!

We are looking at replace 8-10 old XP machines. We purchased a Raspberry Pi to try but it doesn't stream video very well at all. I was recommended by a friend that the Arduino would work better for us but I was just recommended BeagleBone Black. We will basically be using them online using Google Docs, YouTube and other educational sites. It would also be nice if they had VGA output as that is the equipment we have. Do you know of a single board computer solution that is reasonably priced that would work for us?

Using BeagleBone Black...

You could build something using the design materials from http://circuitco.com/support/index.php?title=BeagleBone_VGA to add VGA.

Or, you could use an HDMI to VGA converter.

Or, you could make a VGA adapter out of resistors: http://hackaday.com/2012/06/26/offloading-vga-generation-onto-a-coprocessor/

Or, you could contact CircuitCo for a custom version of BeagleBone Black that included VGA.

Pity that the link from hackaday to the details seems to be dead now

Still, interesting and creative use of the PRU..

Cool! I didn't realize that was possible.

funny, that's what I was thinking

Hehe sounds like a challenge!

The PRU VGA link doesn't point any more to the details, but it could be straightforward, if the video memory location is known. The circuit below is what the 'Minimig' project uses for VGA. PRU#1 could be used, which has lots of PRU GPO capable pins (i.e. the video pins used for HDMI).
