Weather and info display
I have a Pi Model B with a 32gb Class X card. Woot! I also have a wee itty bitty FAVI keyboard for it.
What I would ~like to do~ is feed the composite video out (no sound needed) into my security camera multiplexer. What it does is display multiple security cameras on one screen in a grid.
There are 16 input channels and I have the Pi feeding one of them. It displays in one of the grid squares along with the security cameras. That part of it works great, no problems.
My problem is, getting it to fetch the content I want and have it display it.
I would like to have it run a sequence of "slides" so to speak, with one of them being the local weather radar (animated .gif), then a national weather radar (animated .gif) then a slide with local temperature, humidity, wind speed & direction and when hurricane season arrives, I want to have near realtime updated stuff on hurricanes as I live right on the coast of hurricane alley..
I haven't found all the misc images I want to use just yet but I have three that I can use to help me work out how to do it then I figure I can just expand on it from there.
I know I can use wget to retrieve the three I am experimenting with.
For instance, wget http://ftpcontent.worldnow.com/kbmt/Mic ... s_full.JPG
wget http://ftpcontent.worldnow.com/kbmt/Ext ... recast.jpg
Certainly over time I will find other things I need to add to the "slide show", so to speak.
The forecast, it only needs to be fetched like once every 24 hours. The Current temp, once an hour is fine. The animated radar, maybe twice an hour.
I assume I would use cron to schedule the wget events.
What I am in the dark about is how to have the Pi display them full screen. I don't want to be locked into a browser, I tried Midori and it can load the images but it won't run a slide show and it won't go to true full screen and it won't scale the images to fill the screen properly.
I've been using Linux since I dumped winblow$ back in 2000 but about 2 years ago I became soured from the crummy Suse and Ubuntu experience and built a Hackintosh and have been using OSX almost exclusively now. So my Linux skills have gotten pretty rusty..
I guess what I'm looking for is an image display utility that runs from the command line, that can display animated .gif images, and png, jpg, etc. because the weather stuff I scrape from various locations will be in various formats.
And some guidance on writing some sort of script I guess to accomplish this task.
Another thing I want to do in the near future is to setup my Pi so that I can connect to it remotely via my iPhone to open/close my garage door. I already have it motorized and I have a remote controller I can sacrifice. I bought an 8 channel relay board ( http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0984095956 ) but I am pretty sure I will need some other device to go between the Pi and it. Then I guess I'll need a web server running on it and some sort of very serious authentication method to restrict access to it. I would love it if I could restrict it to a range of IP addresses that it would respond to. I don't know if Verizon assigns static IP's to iPhone 5's but that would be excellent if they did.
Anyway, the garage door thing is a future project. For now I would be thrilled to get my weather/info display system running..
