Battery-less Mobile Technology..the future of cellphone

Here is  a cellphone that  harvests the  ambient energy . What is the Ambient energy? We have a blanket of RF energy surrounded by so many cell towers


Harvesting energy from the environment,is the way to go for future cellphones 
But the cell phones cant be created just by an antenna and signals from it , researchers at University of Washington have their own way to  do that digital communication .

“We’ve built what we believe is the first functioning cellphone that consumes almost zero power,” said co-author Shyam Gollakota
Converting analog signals that to have corresponding  data that a phone can understand consumes so much energy that it’s been impossible to design a phone that can rely on ambient power sources.



They have developed a special way that  takes advantage of tiny vibrations in a phone’s microphone or speaker that occur when a person is talking into a phone.
To transmit speech, the phone uses vibrations from the device’s microphone to encode speech patterns in the reflected signals. To receive speech, it converts encoded radio signals into sound vibrations that that are picked up by the phone’s speaker.

cell proto
The tech is in its nacent stage , but it is a good start !
 In the prototype device, the user presses a button to switch between these two “transmitting” and “listening” modes.

you said Joule Thief?

you said Joule Thief? you said Joule Thief? 

It’s a little wisp of a circuit that allows you to drive aPOWER  LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 – 3.5 V, like from a 3 V lithium coin cell.


But the magic of JT is  a 1.5 V battery like a AA cell simply will work. 
Easy make  Joule Thief,  works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead– down to 0.3 V. 

That’s well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name).

how about a cellphone charger , yes it is doable , we are here to give you  a usable tested diagram .

Why know about bitcoin ?
The digital money trade is steadily heading towards immersion in the North American and European markets. One of the significant drivers of the market has been opportunity from keeping money wallet from hidden taxes and easy to open and keep up a financial balance that is fast raising . The immature managing an account framework in Asia and African market, conversely, fundamentally higher development chances to digital money exchanging stages. While a considerable measure of digital money trade organizations done recent quarter on more immersed Western market, the push to promote bitcoins in Asia and Africa obviously after that wannacry event .
