How To Make A Wi-Fi CCTV Camera System


Worried about being burgled? Leave your PC guarding the house With the right software, your PC could become a powerful home security system, monitoring several areas simultaneously and alerting you at the first sign of any intruders. All you need is a collection of webcams and some know-how.

Firstly, install the trial version of Active WebCam. It displays a ‘Trial version’ logo but won’t time out, so it’s good enough for us. Launch the program, set up a camera and select ‘Settings | Motion Detection’. Make sure motion detection is turned on, with the sensitivity you need it to be (turn it down if there’s a pet wandering around to reduce the chance of accidental alerts) and tell the program to alert you via email should it detect something.

Now click ‘File | New Camera’ to add each new camera, using the Motion tab to define how it’s treated. That’s just about it. Test Active WebCam by sending someone into each area and confirming that you’re notified, then just leave the program to watch over your home.

Now Laptops Will Be Charged By Just Typing


The day is not too far when you will be charging your laptop by just typing on it.Researchers in Australia are studying how piezoelectric could charge Laptops and other devices through the mechanical pressure generated while using them.
In a study published in Advanced Functional Materials, Madhu Bhaskaran from RMIT University in Melbourne and colleagues for the first time managed to precisely measure voltage and current generation for nanoscale piezoelectric thin films.
“The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers–essentially creating an everlasting battery,” Bhaskaran said.
As she explains in the interview below, Bhaskaran says the amount of energy that can be generated by the thin films is about 10 times less than what’s required for portable devices.
The next step in her research will be to boost power output to develop low-cost, compact components, which could take about three years. These pressure-activated components might one day replace conventional batteries.
All the more reason to perfect your typing skills.
