Do you still remember the H1N1 outbreak in Asia? The manifestations are usually flu-like symptoms which includes fever, cough and colds. The best way to detect fever when people are arriving from the affected areas was to use a thermal camera. These were widely used in Asian countries especially on airports but not all can afford one because it’s very expensive.

We can all agree that this is the greatest deal ever! A thermo-cam which costs around 100$, now there is no reason it can’t be bought by even poor countries to help prevent the spread of the disease. Credit must be given to inventions like this because it’s really a big help.

There are occasions  when you want to view your video clips taken in your digital camera on  your TV.You can do so by interfacing the camera video output to video input of your TV.But this times you cant connect directly as it needs some amplification before the signal reaches from camera to television

The video amplifier schematic circuit shown in the figure is a simple PAL video amp, expected to have a 3db bandwidth of 5.5MHz. You can connect your camera to TV through this circuit. So this is a low level transistorized video amplifier stage that accepts 1V (p-p) and outputs 2V(p-p) signal. 

Notes The circuit requires a 5V dc power supply
