• I entered the Campus and the first thing i saw was the Inferno Throttle. A small racecourse set up for the racing of remote controlled cars. quite nice.
• then next we went on to see the  Military weapons and defence things used by the defence department of the Government.  There  were quite a bit of them and very practical in use.
• We further went to down walking without any idea and we reached the area of Robowars. There was a glass cage set up and there were two robots at a time. The robots were with blades spikes and all things to ruin the other robot. It was like nuts ans screws around all over (not really). One of them was nice in which one robot took the other above it and made it immobile.
• Next we walked around and got into a enclosure where an old gentlemen was telling us the correct use of digital cameras and DSLR's even till the fact how to hold them. He told us why film cameras are out of use. He also told us the difference between the ethical and unethical means photo editing. The gentleman also told us:

The world runs behind more mega-pixels, but it isn't about that. The sensor of the camera has to be good. An 7 mega-pixel camera can do a better job than a 14 mega pixel.

• We further kept walking, now we reached the open ground. out there people were flying radio controlled air planes made by themselves. all one could see in the sky was air planes(not completely but somewhat). Some made an awesome flight whereas some did not survive. Anyways nice experience.
• Later in the night we saw 3D Holographic view at the Open air theatre with a public of over 10,000 people! Next what we observed was just amazing. Mountain Bikers from M.A.D had entered and showed us some of their brilliant stunt moves!

Day 2

• We jumped into some action and played lazer tag. The game is seriously fun and i think everyone must play it once. It's just like playing shooting games, in reality and also no one gets hurt this time!
• We had a look at the A.N.T.Z competition where students of IIT and other participants had prepared robots and were to walk on certain paths and were acquainted with sensors to sense objects and move them aside and then continue their path.
• Dr. Lars Rasmussen (Co-Founder of Google Wave and Google Maps) was also there and after waiting for 1 hour in a long line we got a chance to listen to his words. We'll be posting of what all he said in the next post!
• Just after the event we lined up back again for the entry at Open Air theatre. Tony Chapek (master illusionist) and Nexus Europe which a group of Artists who do dance, kung foo and acrobatics, all in one mashup performance which the crowd loved!

Well, these are some handy and easily applicable tips to save your mobile phone battery:

• Switch of the phone when not required. When people go to sleep they leave the phone on, this causes loss in battery without even using it, rather switch it off if not in use. When in a remote area, switch off the phone because the phone isn’t able to find network but it still wastes its energy trying to find it, better to switch it off.
• Keep the vibrator function of the phone off. The ringing tone is enough. Even try to keep the volume of the ring tone as low as possible.
• Keep the Bluetooth always off unless needed. Bluetooth drains the battery. With Bluetooth on near virus-infected phone may cause damage to the phone.
• If your phone has features in the phone like Wi-Fi and GPS, keep them also off as they also eat up the battery.
• When you know that you will recharge your phone after a long period of time, avoid using features which would drain up battery. For example flash photography. It completely exhausts the battery very quickly.
• Keep the back-light in the phone either off or put the back-light timer really low. This will minimize the depletion of the battery power.  Some phones have light sensor, it switches off the back-light when there is light around and turns it on when light is not there or it is minimal.
• Try keeping calls as short as possible as this will also minimize the depletion of battery. Talk abt the main point or if the call is getting extended unnecessarily then make an excuse and cut off.  If you really have a will to conserve battery talk to the point and for a limited time.

Hope this post will help everyone to save their battery and will be free from the complaints of battery exhaustion without using it much.

1. Use up the power of the battery as much as possible.
2. Put them in a plastic bag and seal it.
3. Place the bag in the freezer for at least 24 hours. Overnight is sometimes enough.
4. Take the bag out of the freezer and leave the batteries to return to room temperature. Do wipe of the condensed water of the batteries before using them. Leave them sun for a few hours to dry.
5. Fully charge the battery, then use them again,  get the power as low as you can get it. Repeat this charge-discharge cycle a few times, and see if you get a longer life.

Your mileage will vary, but two of the experimental 4-year-old batteries are now useful. We get between 2 and 4 hours from one of them, depending on the load of the gadget. You can do this with cellphone batteries, or batteries from lots of other gear.
