Reverse Engineer DDPAI Dash Cam Firmware

10 Oct 2019

I have been looking for a good mid range Dash cam for my car. I was thinking to integrate this to my custom build infotainment system. For this, there need to be some option to get live stream. I bought this DDPAI Mini Car Dash Camera from Amazon Link (Official site Link), but I was not sure whether I can access the live stream or not. The product looks good, companion app works smooth also, and there is live stream in the app. My goal was to figure out a way to get live stream so that I can use it in my program. May be have a look at it’s firmware and do some little hack if possible.

Product Design of a 4 wheel differential drive robot

Warehouse Management System using Drones

This is a project I had completed while doing internship at EY. The idea is to automate inventory and the stock checking process without any human intervention. Today these are all done using human resource. This is a really tiresome work because it involves manually inspecting each pallet (box) and read the QR/Bar code associated with it.

A Multilayer Neural Network Based Obstacle Avoiding Robot | ROS | Simulation

21 Oct 2015

This is an obstacle avoiding robot which I and Sooraj Krishna built in ROS using STDR simulator. The robot is making decision based on a 3 layer Neural Network. The learning algorithm used is back-propagation (which we wrote in python). The network design is shown below.
