Super "Power".........as the sun shines(1)

 A solar circuit is presented here is… a device for collecting sunlight. To keep things simple, we’re using a single nicely made small solar panel for all of these circuits. The panel that we’re using for these circuits can be procured from Dx.com for as low as Rs325/- .

Why  this panel ? 
its a  Polysilicon Solar Panel. 

Easy to connect 

This epoxy coated for toughness. On the back of the panel are two (thin) solderable terminals, with marked polarity. (While you can solder directly to the terminals, be sure to stress-relieve the connections, e.g., with a blob of epoxy over your wires.) .This guy throw a nice little 90 mA,  to 120mA . That is tiny power to be harvested with a super cap . 

Where to Use 'The circuit ' 



 well there are couple of use cases  viz smaller controllers that need 'small power' 


 blinks 



 Example : water level sensor 

 road safety blinker 
 plant water reminders 
 even a battery saver calling bell 
  
We will come with the viable circuit to be used in next post ... 
After GST rates were fixed importing is easy .

A typical experimenter   board can be  easily made with digi spark https://potentiallabs.com/cart/digispark-attiny-85-online-india-hyderabad

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 .
