circuitbasics :আইচি বোৰৰ পিন কেনেকে উলিয়াবা

Open up a television or a radio and you'll see many parts that it's built around a printed circuit board (PCB): a bit like an electric street-layout with small circuit components (such as resistors and capacitors) in place of the buildings and printed copper connections linking them together like miniature metal streets. Circuit boards are fine in small appliances like this, but if you try to use the same tricks alike to build a complex electronic machine, such as a computer, you quickly hit a snag. 
So to get the  best of the small space IC or 
integrated circuit


Lets learn how to get the pins to follow a circuit diagram 


This is 555 EGG timer  it will shut off egg heater after time delay or it will BUZZ 


Lets  find the  pins of the IC ! 




555timer টোৰ পিন দেখাইছো , কাত তোৰে বাওঁপিনে ১নং পিন ... তাৰ পৰা ২,৩,৪...
একে দৰে CD4017(runing led IC) টোত পিন দেখিবা

MakeINAxom is a dream that will shine Assam and NE Region .....
এই ব্লগত  SELABS বোলা অনুস্থানতোৰ সপোনক ৰাইজলৈ নিছোঁ 
SELABS কি  , কি কৰিব বিচাৰিছে ?     SELABS organization বনাইছিলো অকলেই , ইয়াৰ আৰম্ভনিত ২-৩বছৰে ফেচবুক গ্ৰুপ   "SOHOJ ELECTRONICS TALK AXOM"  ত  ইলেক্ট্ৰনিক্সক লৈ কেনেকে প্ৰদাক্ত বনাব সেইয়া লৈ আহিছিলোঁ

   The "SOHOJ ELECTRONICS TALK AXOM" face book group has been pioneer in bringing electronics and DIY to all in a simple way .It has acquired 9000members in 2 years that include people from all spares of job  / academics .  ---- SELABS কেনেদৰে বিপ্লব কৰিব বূলি ভাৱিব পাৰি ? SELABS প্ৰথমে বনাইছে সহজ-ইনভাৰ্তাৰ  ৩ ৰুমত ১০০% উজ্জল লাঈত দিব দামী ইন্ভাৰ্তাৰৰ দৰে ।  কেবল ফেন আদি নচলে বেচিক মদেলত ,কাৰ দাম আৰু বেতেৰী যি দৰকাৰ তাৰ খৰচ কম ৰাখিবলে ।

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 .
