Assignment 13 : Applications and Implications

°What will it do?

I am making"Biometric Smart key security System"at Vigyan Ashram,this system will automatically track the which key is taken by whom using biometric(Fingerprint sensing) system it will reduce the manual effort and mess occured due to manual handling I explained the sketch and idea of my final project in

Final project

Assignment 1

as well.
In my system,fingerprint sensor will verify the authorised user from store data then it will open the door of box then using matrix or touch screen mechanism my system will display and store the data for tracking .then after some time of activness door will close.

°Who's done what beforehand?

In market there are number of biometric system are exist for different applications like door lock system or biometric attendance system but in my case I am using Biometric or fingerprint security system for different application I didnot found anyone who used this mechanism for same application.Their are number of tutorial and video on You Tube for similar mechnism,I will use some technique from them

° What will you design??

For my final project ,I designed the frame structure,whole box,keyholder,Limit switch mount for laser cutting.

I designed hinges & door handle for 3d printing.

For electronic part I designed my development board.

For communication between two boards I used neteork communication through i2c module.

° What materials and components will be used? How much will they cost?

Material & Cost

I am gonna use metallic tubes for external container ,I will used it from our scrap.

acrylic sheets 3MM 4X8: INR 920

3d print material(PLA/ABS):INR

Electronic Component : INR 3886

You can find the detailed prices of all components in the BOM .

° Where will it come from?

Most of the electronic components are availabale in our inventory,for remaining component like fingerprint sensor and battery,etc. I ordered from

Amazon and Robu

° What parts and systems will be made

Parts I am gonna made:

I will made metallic frame using workshop tools

I will made Wooden key holder using laser cutter

I will made acrylic frame covers using laser cutter

I will made 3D printed hinges and door handle

System:Microcontroller Board

I will made Microcontroller board for whole system operation i.e.operation of door lock system ,fingerprint verification system and key tracing,Board for input and output devices using SRM-20,soldering station.

° What processes will be used?

Laser cutter for the frame cover

3D printer for the hinges and door handle

Milling machine to produce own PCB boards

Soldering station to solder own PCB's

Other workshop tool and processes like welding ,cutting and bending

° What questions need to be answered?

This is very interesting question,right now I have a very big and imp question that "how to complete the project in time?" with satisfactory output, and solution is follow the "Giant Chart " honestly.

°How will it be evaluated?

Definitely, when the whole system will be finished I will show it to Mr. Yogesh Kulkarni Sir(Director of Vigyan Ashram) to get his feedback in terms of aesthetics and if the functionality is enough and easy to use for the Ashram. I.e. do they understand how to authentize and trace the keys.After that I will take feedback from my instructor during the process. Mainly, I needed their help for electronic process and microcontroller board.

my project involves some 2d and 3d designing parts,I am using additive and substractive processesnas well where I can useI am trying to make whole and sole part by my own but tyes their are some limitation like I am unable to make my own fingerprint module,but I am making door handle and hinges ,pcb boards rather than purchasing.

For proper packaging and look I am making separate compartment for electronic boards and devices to avoid maximum mess.

Summary

In this assignment I understand at what position I am right now in project completion?where I need to take more efforts, where still I am lacking in short I understand my project is going as per my planning or not.
