new project idea

With the end of my end-sems, my mind is now completely free to plan out my next project. 2-1 was very exciting and provided lots of basics of electronics for me to apply in later stages of my career. One important field was Logic Designing that thought me the basics of binary. Armed with this tool, an engineer can design anything that suits his needs.

Few days ago I noticed a lack of security in residential buildings especially apartments. I wrote myself a problem statement:
Build a security device that protects an apartment and is easy to use. The device should be built according to the needs of a family of four.

I came up with this problem statement with my house and family as the test area. The door of house consists of an auto-lock feature, on closing, that can only be opened, from the inside manually or from the outside using a key. The system is made by Godrej.

I have started analyzing the problem statement. More details in next post.

the cockroach controlled bot

I found this video on youtube. Its an amazing adaptation for controlling a robot. Its not very difficult to build the robot but the idea is too good. Its got a very simple mouse rollerball mechanism consisting of sensors. One thing, I dunno how they managed to keep the roachy on the robot? Any idea?
