A modern power supply is
|
||||
essentially a DC-DC converter.
|
||||
Therefore it first rectifies
|
||||
the AC power from the wall
|
||||
into DC.The nice thing about
|
||||
Such a converter, is that it
|
||||
can take a whole range of
|
||||
input voltages and still
|
||||
Output a constant 12v for our
|
||||
Pc components.A cheaper power
|
||||
Supply might use cheaper parts
|
||||
in the primary side, which is
|
||||
Why it will only be rated for
|
||||
200-250v.

We exclude cost of pump.

And I dont know why my PCB is not loading from semantic and its staying blank probably due to something I added in semantic but its passing the tests.

Components:
|

|

Since most of the components are bought through mouser shipping and custom charges will be included extra. (Assuming 30% extra then material cost given in online store) = 6930 Rs. (and 40% of the cost is just 2 arduinos, Lol chip shortage is real)
|
||||
|
||||
PCB Printing:
|
||||
I used pcbway estimator to calculate the cost (https://www.pcbway.com/HighQualityOrderOnline.aspx)
|
||||
My board is 58mm x 38 mm, 2 layer => $ 116 ~ Rs 8900
|
||||
|
||||
Assembly:
|
||||
All the components are either through hole or 0805 package, hence it can he hand soldered. Assuming this assembly charges will be only the soldering lead and consumables used. Hence Rs.250 can be accounted for assembly.
