Topic: Use Chumby as output display device ( through a webpage)

So I have an idea to use the Chumby as a display device for my laser cutter.

My idea is to have an arduino write to a webpage served up on the Chumby or display one served up from the arduino. My problem is that I am not sure where to start.

I am sure there is some info on the wiki and buried in the forum but have not been able to piece it all together. Any help pointing me in the right direction would be greatly appreciated!

Re: Use Chumby as output display device ( through a webpage)

What model of chumby are you hoping to use?  I've compiled the qt webkit demo in kiosk mode based on a couple topics on these forums that works to display webpages.  It's actually a pretty slick setup.  For my purposes I have it all run through a debugchumby script.  That means I plug in USB stick, the Infocast 8" turns into a kiosk that goes to a webpage on boot, I unplug the USB stick and it's back to stock firmware.

There's a simple web server built into most of the devices, see documentation here:

For more substantial use than that, there's a prebuilt version of lighthttpd available here (scroll to the bottom):

There are some prebuilt languages you can use for CGI here:

Hey Duane and Masterdaddy,

Thanks for the reply and information.

After posting I realized that I had not properly thought out what I was trying to accomplish and did not put my question in the proper context. That said, I am now closer to putting my idea into action due to your help.

I am going to use an Infocast 3.5" as the display. An arduino will be the server and a browser on the infocast will read the info from the arduino web server. It helps when you use the proper terms for your ideas! DOH!

@Masterdaddy Will your QT browser work on the I3.5?

Thanks again,
Larry

I've never actually tried.  I'll have to pull out a I3.5 soon and see if it does.  I don't remember if anything like display resolution was hard coded or not, but in any event, it should be possible to get it to work with little change.

I will let you know if I get to it before you do. Thanks for the info.

It looks like there's a link to a prebuilt C1/I3 web browser at the bottom of this page:
