MAKING %) WATTS BULB FROM WATER BOTTLE(zero electricity needed)

Posted: 26 May 2011 01:04 PM PDT

just i found a cool method of light harvesting which is very cheap and amazing.

Using just a 2 liter bottle(plastic or glass, plastic bottles are highly recommended while concerning safety), 2 lids full of bleach and a camera film dispenser you can build the cheapest solar energy harvester.

MY THEORIES: MAKING 50 WATT BULB FROM 2 LITER BOTTLE - ADVANCED CHEAPEST SOLAR ENERGY HARVESTER

here in this blog i given directions to make the bulb.If any one have doubt just let me know.

Human blood acts as mermister

Posted: 26 May 2011 12:49 PM PDT

Indian scientists found that the human blood has the property of MERMISTER'S.
They proved that human blood changes its electrical resistance depending on how much voltage is applied. It also seems to retain memory of this resistance for at least five minutes.

I am ready to explain about mermisters if any one interested in it.please raise your questions here

How to search driver's for our system ?

Posted: 26 May 2011 08:37 AM PDT

Hello friend's
I found that lots of people found difficulty in find the driver for his/her system.There are some software which helps the people to find the correct driver for his/her system but for this you have to pay some amount.
So i decided to build a open source software.
.
I listed here some way to find driver for our system.

1.Search by vendor id and device id.
2.Search by your motherboard model.

But i it is not sufficient to search a particular driver for a system.I faced some problem while searching a sound driver for our system.
Any more idea ?

Students from BYU have modified a bike to be 40% more efficient. The students used a 2 Galleon tank and reduced the battery size. However they did not exceed the original weight of bike. :)

RF Transmitter Receiver

Posted: 26 May 2011 02:43 AM PDT

Hey all!
I have just constructed a RF circuit to try out. I made use of the T5-434-5V and the R5-434-5-128 transmitter and receiver pair and also the HT12E and HT12D as the encoder and decoder for the transmitter and receiver respectively.

The schemetic I used can be found on page 6 of this datasheet: http://www.spelektroniikka.fi/kuvat/T5R5-434-5V.pdf

After following exactly, the circuit does not work. I connected the DOUT of the encoder and the DIN of the decoder directly and it works, which brings me to suspect it's the RF pair that's not working.

HT12E oscillator resistance: 1M ohm
HT12D oscillator resistance: 51K ohm

If anyone has any idea as to why the transmitting and receiving isn't working, your comments would be greatly appreciated!
Thanks!
