Retrofitting LED Lamps into Smart Lamps

Permalink 1 minute read Modified: (rhnvrm)

Objective of this project was to show as a proof of concept that we can pick up any off-the-shelf generic lamp and by implementing minor hardware changes using an arduino, convert it into a Smart Lamp. We have implemented lamp switching based on environmental factors (such as Temperature, Light intensity etc), hand gestures (such a clapping actions), which can be set up by the user by attaching triggers to various conditions in the User Dashboard which was made in Processing 3.

Survey Paper on Security in Wireless Sensor Networks

Permalink 1 minute read Modified: (rhnvrm)

Wireless Sensor Network is an emerging area that shows great future prospects. Today such networks are used in many industrial and consumer applications, such as military, industrial process, monitoring health and in automated and smart homes. So far, the researchers have only focused on making WSNs useful, feasible, and less emphasis was placed on security. The sensors used are susceptible to different types of attacks, denial of service, physical tampering. In hostile scenarios, it is very important to protect WSNs from malicious attacks.

Working with J2ME on Linux in 2017

Permalink 2 minute read Modified: (rhnvrm)

I recently had to work on the J2ME platform for a course at my university. It is an old technology and does not have many recent articles about using or installing J2ME on Linux. J2ME SDK has had no support for Linux for a long time. The SDK 3.x only has support for Mac and Windows. The last version available was by Sun which is called the Sun Java Wireless Toolkit 2.

BLIP – Asset Tracking & Location Based Contextual Services Using Bluetooth Based Indoor Positioning

Permalink 2 minute read Modified: (rhnvrm)

BLIP is a naive solution for effective tracking of assets in indoor spaces, where satellite (GPS) based positioning systems are unreliable, and provide location based contextual services. This project was made at IndiaHacks: Internet Of Things Hackathon at SAP Labs, Gurgaon. It was an overnight hackathon and Paul and I were awake till the last moments and only slept after creating a small demo video. We were inspired by the The Time Machine (2002) movie’s scene where the protagonist enters a museum in the future.
