Python “Mobile Snakes” presentation

Back in November I gave a quick presentation to the Perth Django/Python Users Group.

It covered a brief history of Python on mobile devices (Maemo/MeeGo/Nemo/Sailfish), and an example Python/Qt application which has a custom UI for each platform.

The slides can be downloaded here:

Fremantle Line: Transperth Trains Live Departure Boards for N900 and Ubuntu

I have been playing around with pygtk (python and GTK), and have managed to come up with something resembling an app to provide live departure times for Transperth trains:
Perth Train Departure Board
I’ve named “Fremantle Line” after Maemo 5’s codename, Fremantle. It is also the destination of one of Perth’s 5 train lines.

It also works in portrait mode:

It is primarily intended for the Maemo 5 platform on the Nokia N900, but will also run under Ubuntu:

Still needs plenty of work, but I am finding it quite useful while out and about in Perth.

Configuring iiNet VOIP (iiTalk) on the Nokia N900

iiNet VOIP iiTalk N900

I just succeeded in configuring iiNet’s VOIP service (I get iiTalk free with my DSL connection) on the Nokia N900 mobile phone. One of the many great features of the N900 is that it has completely integrated support for Mobile, VOIP, Skype, and Google Talk calls – you can make and receive calls on these services just like a usual mobile call, straight from the address book.

This now means I can use iiTalk from my handset, rather than using a headset hooked up to my desktop computer.

For reference, here are the settings I configured on the phone:

Remember you will also have to configure port forwarding to the IP address of your phone on your wifi network – read iiNet’s documentation for details.
