please Help!! @Microhydel power generation system for building roof rain water Project

[remon7]

I have seen a video about electronic Project, now days I am trying to implement on my final year project. Practically I face with some trouble... for example. Real project they are getting 3+ volts/ampere from their project, but now I am getting 1.2volts, secondly how can I adjust everything’s. Like resistor, capacitor etc. on breadboard. Which things are important (parts/components) in this project? Focus: I want to turn on a light (6/9) volt battery. But my generated voltage is 1.2V. How can I increase these volts, I would like to turn on lights or charging battery (source). I would like to turn on my light or battery at the list. als I am planning to buy parts (transistor, resistor, capacitor etc.) today. So please tell me which things I have bought today, I have to finish this project by Friday. I have exam on it. also I need to write papers for it. Final Year project.
Real video:

and about my project thats i am preparing :

also this image: https://i.imgur.com/OG4Gcs7.png <<< Structure of my project.
please give me advices about this project. I will go to Electronic Shop for my project. So please give me list of parts, I will buy these this things tomorrow!!!
Hope everyone can give me your value advices about my Project.Waiting for you.Thanks for you in advance. Please known me. detail .

look this picture ... its mine project structure .

 

[remon7]

Thanks in advance for any input or recommendations !!!

 

[remon7]

i would like to share with you about my project related a doc file. please tell me which components are important for my project, i will buy those parts. today.

but now I am getting 1.2volts

You cant do much with 1.2volts if you need to charge a battery.

 

[remon7]

please reply today i will buy some components for my projects

We don't do your projects/homework for you, although we can give guidance. Tell us what you have done so far towards the project, what you think you need to do next, and any particular part (besides only having 1-2V to work with) that you are having difficulty with.

ok how to design boost converter for 2volts to 12volts or 2volts to 6 volts . i have to focus on it now for this project.

 

[alec_t]

There are many designs out there. Google 'DC-DC converter' or 'boost converter schematic'. That will give you a start.

 

[remon7]

thats sounds are good , yeah i am looking info in google rightnow . after study i will message you ... already i have explained detail....help me

 

[remon7]

i have read this article about boost up converter its quite perfect for my project. they discussed about 1.2volt to 5volt maybe it will work on my project or not. please reply me.
Its for
Step up dc converter 1.2v to +5v/-5v for micro computer
https://www.eleccircuit.com/step-up-dc-converter-1-2v-to-5v-5v-for-micro-computer/
Boost converter 5V to 12V
https://www.eleccircuit.com/boost-converter-5v-to-12v/ But its really impossible about generating 5volts from micro hydro electric project.

Thanks in advance for any input or recommendations ..

The first circuit you linked to looks as though it meets your needs. Simulation shows it should be able to provide ~ 15mA drive for a LED. Output voltage can be increased slightly by reducing the value of R2 and replacing the zener diode with e.g. a 5.6V one.
Don't forget to acknowledge the source of the schematic. Good luck with your exam.

Thanks Alec ....Thanks for your collaboration!!!!

look this website https://projectlistinfo.blogspot.com/2013/01/how-to-make-digital-voltmeter.html
actually i am confused about its circuit setup can you help me about it ...

 

[alec_t]

What about the setup do you find confusing?

 

[remon7]

i am working on it. its digital voltmeter. i bought all components. But i missed one capacitor..470nf ,,But i have 47uf ..is it similar. can i use it there ? Thanks

 

[remon7]

Look this picture please ....in a 7 segment display which pin is called DP ?

 

[alec_t]

i missed one capacitor..470nf ,,But i have 47uf ..is it similar. can i use it there ?

No. It must be 470nF.

which pin is called DP ?

According to the schematic pins 4 and 9 are the decimal point connections. Check the datasheet for that display.

 

[remon7]

Datasheet means ?

 

[remon7]

unfortunately i don't have this capacitor . soo have u any idea ? without this capacitor can i run this voltmeter? 470nf capacitor !!!! I have 47uf
