qt-ping-grapher

This is a super basic, super dumb PyQT app designed to take over your Raspberry Pi's external display and show just how terrible your ISP is.

Installation and usage on Rasbpian (rasbmc)

Simple:

% sudo apt-get install git pyqt-tools pyqt4-dev-tools python-setuptools python-rrdtool # just in case
% git clone git@github.com:nphase/qt-ping-grapher.git
% cd qt-ping-grapher
% ./start

FAQ

What does it look like?

Pretty bare:

Help! My screen keeps going blank!

I had luck after modifiying /etc/lightdm/lightdm.conf to: xserver-command=X -s 0 -dpms under [SeatDefaults]

What does ./start's export DISPLAY=:0.0 do?

Just sets the default X server target in case you want to run it from the terminal instead of a local console. I don't have a keyboard attached to my Rasperry Pi, so this makes it simpler for me.

What if I don't have X installed?

Then you can't run qt-ping-grapher.

Who is getting pinged?

www.google.com. You can change that at the top of app.py

Why did you build this?

A convenient and useful excuse to play with QT and build something in python. It's been a while.
