Project Funding & Contribution

Note: This project was developed, planning & code C++ and microcontroller entirely by  Akashdip Mahapatra , who is not a permanent member of the team but volunteered to lead the design, development, and execution process. And    Arkadip Mahapatra  (my little brother, Class X - WB board 2025) devloped the complete Design and electrical circuits & connection of the project development, with code feedbacks and suggestions.

Soumyadeep Koley (One of the core team members), contributed significantly by procuring hardware parts worth ₹800 and also transferred around ₹4400 for project development expenses.

As the project budget exceeded ₹4400, Akashdip personally covered the additional costs to ensure the completion and quality of the final output.

Total Project Cost: ₹ 6916

There are many things to buy from the Kolkata shop but some items are damaged due hit and try ⚡ because it's the first time so I can't know the actual voltage or circuit.
Due to the experiment some items are damaged. like :

SMPS

I need 4-5 amp but it's not available in the shop this time so i buy 3 amp

Hold

Capacitors

Without SMPS the 230v AC directly converted to 325 DC (230 x √2) which is too much then our using capacitor rating ... So that's why it cannot control the current and blasted

Hold

Raspberry pi pico

The gate in IGBT need around 15 volt, But in Raspberry pi pico logic level is 3.3 volt, so the potential difference between Brass Rod & aluminium sheet never became arround 60 voltage

So I add extra power supply and it's completely damage. Then i use Arduino NANO 5 volt logic page link
