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 . get the ring toroid from a OLD smps of pc !

MakeInAxom: inverters reaching to villages OCT2017

We were covered in http://achhikhabre.com/kaushik-hazarika-sohoj-electronics-make-in-india-make-in-assam/ Who made the case ? Well I have handmande every case . Used strongest resin glue for front panel . The cabinets have a screwless look and sleek feel . Here is a real image : Many months of research for low cost inverter has given proven results . As I approached the poor to deliver 11-12hours of full light via a inverter the response was phenomenal . Faults issues and more fixes ......... Do the inverter have issues ? yes as of now 2 issue exist 1)if there is heavy spark at load the backEMF fries the low cut chip 2)no load voltage shoots to 400V so may fry few LEds but is the bulbs are secured they are not of that big concern , the mass delivery version will have the fixes for these .
