Electricity scanner by Tero Paananen (tepaa) is an application used to gather statistic about the electricity usage in your house real time. Usually the meter installed by the utility company has an LED that blinks at the speed that is relative to the usage of electricity. This application is consist of two parts in order to scan the LED blinking and calculate its statistics.
1. Server : The server application is implemented using Qt which scans LED light blinking (in kWh) from the electricity meter. This application calculates a real time electricity usage. Server application uses UDP for broadcasting kWh data to the clients.
2. Client : The client application is based on Qt and Windows Phone as well. The client receives kWh usage from the Qt server and shows the calculated kWH usage data in a textual and visual format. You can visit Qt ElectricityApp app and Windows Phone ElectricityAppWP application for detailed descriptions.
Qt Client and Qt Server talks via WLAN UDP sockets and Windows Phone Client and Qt Server uses TCP.

Wojciech Nowanski, COO, and Muhammad Ahmmad, Creative Programmer, at Psiloc talk about developing World Traveler —an app for business and leisure travellers — for Nokia Asha Touch phones that was created using the latest Java tools from Nokia Developer.
Nowanski explains how the application arose from the frustration of not being able to get information about a delayed flight. Now World Traveler puts flights, currency, and world time information at Nowanski’s fingertips.
The app took a small team four months to produce. In addition to the features of the Nokia SDK for Java, the LWUIT was of particular benefit in speeding up the development ‘because it has a wide variety of UI components and we don’t have to worry about implementing from scratch,’ says Ahmmad.
The most significant aspect of the development was that ‘Series 40 devices are getting smarter and more powerful, allowing us to create richer applications,’ according to Ahmmad.
