PUBLIC GRIEVANCES

Posted by rajascientist Sunday, August 2, 2009 0 comments

Government of India has an online Grievance forum at http://www.pgportal.gov.in

Can you imagine this is happening in INDIA ?

The govt. wants people to use this tool to highlight the problems they faced while dealing with Government officials or departments like

11) National Saving Scheme of Ministry of Finance
19) Central Universities
20) ESI Hospitals and Dispensaries directly controlled by ESI Corporation under Ministry of Labour

Many of us say that these things don't work in India .
Couple of months back, the Faridabad Municipal Corporation laid new roads in his area and the residents were very happy about it. But 2 weeks later, BSNL dug up the newly laid roads to install new cables which annoyed all the residents.. A resident used the above listed grievance forum to highlight his concern.. To his surprise, BSNL and Municipal Corporation of Faridabad were served a show cause notice and the guy received a copy of the notice in one week. Government has asked the MC and BSNL about the goof up as it's clear that both the government departments were not in sync at all.

So use this grievance forum and educate others who don't know about this facility.
This way we can at least raise our concerns instead of just talking about the 'System' in India .

CRYSTAL RADIO

Posted by rajascientist 0 comments

A crystal radio is the distilled essence of a radio. It has very few parts, it needs no batteries or other power source, and it can be built in a short time out of things you can find around the house.






The reason a crystal radio does not need any batteries is the amazing capabilities of the human ear. The ear is extremely sensitive to very faint sounds. The crystal radio uses only the energy of the radio waves sent by radio transmitters. These radio transmitters send out enormous amounts of energy (tens of thousands of watts). However, because they are usually far away, and we have at most a few hundred feet of wire for an antenna, the amount of energy we receive with the crystal radio is measured in billionths of a watt. The human ear can detect sounds that are less than a millionth of even that.


The above circuit shows a simple crystal radio. U can also add some capacitors to the above circuit, a capacitor in series with the antenna coil allows high frequency to pass through enabling better performance and reception.




Instead of ear phone u can also use a telephone receiver to listen to channels.
