Hi, I'm from Brazil. Good project's. I Liked. In circuit number 6, the 150R resistor is before the negative of the source and in the schematic is after. But it works anyway. Thanks for sharing.
With the second circuit the transistor will get quite hot actually, because the current will be 10W/12V = 0.8333 mA while this particular transistor only support 500mA continuous. you'll need a more powerful transistor with maybe a dissipation pad.
The last circuit with a smaller capacitor will flash faster than you can see (above 30Hz) and makes an energy saving lamp (white LED chopper circuit) .
hi guys, the greatest success that I have ever had was with the Gregs Electro Blog (i found it on google) without a doubt the best course that I have ever followed.
You know bro....... You really are a genius, really.👍 But we can't really find the necessasities to complete the circuit, if you have any solutions to get these materials, please notify.😎 But anyways you really are a genius man 😀 and I hope for the best of you. Good Luck 🤞
Hii bro iam bharath. , iam a new subsciber to ur channel. , awesom vidios bro , bro plz contine doing this typ of short experiment plz plz and thanks for making
I want to make an Automatic Night Light using an LDR. But in the video at 2:12 I see you added a 33k Resistor. Between the Positive terminal and Base of BC547. My question is that why do we need that resistor? Will the Night Light work without that resistor?
That was great and simple , but I didn't got the reason of the relay (6 volt) you showed us in the first circuit, simply because you didn't use it at all? Or it was just a fault? But after all it was lovely video
@ASHORSHEMAYA I\'m not sure but ,if anyone else trying to find out how to make electronic circuit boards try Letza Easy Electronics Lessons (just google it ) ? Ive heard some pretty good things about it and my co-worker got great success with it.
I have a 24v 8.5 amp dc motor.. its take for run lot of current its mean ampier so I need to reduce my current cost also ..need run same speed.. pls give solution
So it should not be out of the question to come up with a burglar alarm that when a beam of light is broken turns off an electromagnet and allows a door to slam shut..... how about it?
sunt fascinat de montajele dumneavoastra si de prezentarea lor, va multumesc !
I am fascinated by your montages and their presentation, thank you!
Welcome
Bahut hi saandaar video thi 👍🏻
That's awesome. I tried 3 bc547 projects on my channel to see if it works.
Nice Experiments 👍Realy Creative video 🎉
What a delightful video and technique! Who needs circuit diagrams!
People who want a clear schematic, but ok I guess.
I need

Very helpful video. I like this type of video.
Very nice
Really useful for me 👍♥
Thank you
Your board less circuits are elegant.
Thank you
The led chaser is a work art !
Really enjoy, Thanks. I learn a lot by simple projects.
Welcome
I really like the way u solder the components
I agree with you
Amazing video and your soldering are just as amazing. But, I didn't get the idea as, how can a transistor work without connecting base?
You have good soldering experience
Last project 10:50 minutes lo Led's 10 use cheyyocha
You know bro.......
You really are a genius, really.👍

Very nice bro video good job
2:44 how to destroy a BC547 with 10W led !!
If Rb = 220k
Ib
I think it's better if there is schematic diagram for each project
Excelente vídeo, muy buenas ideas, gracias.
It would be great to see some schematics of these projects.
In which u used relay??
Good work, kindly explain the circuit in the description.
In first circuit, how to adjust the time of led glowing. I want 5 sec
Hi you can do that using the same circuit by increasing the capacitance or put one more that type capacitor In parallel
I really like that.Thanks.😊
Thank you for wonderful video
Awesome 👍 stuff!
Thank you
Thanks a for uploading this video. It has been a big help to me.
Hii bro iam bharath. , iam a new subsciber to ur channel. , awesom vidios bro , bro plz contine doing this typ of short experiment plz plz and thanks for making
Audio amplifier ke liye 5v chale ga kya?
Muito bom! Parabéns nota 10
Thank you
7:28 Amplifier for or speacker 10W you need transistor 10W too! But is minimum.
I love you're series
Bonjour, votre vidéo très intéressante, c'est l'électronique pratique, j'aime.
You have good soldering skills... Make a video on how to solder nicely like you.
Yes I would like that too
Just watching this video has given me ideas on how to up my soldering mojo!
best soldering melting point 330°C to 350°C (626°F to 662°F) and pre-paste
Ya nice soldering
Practice. Get old trash electronics and desolder and resolder everything. You will be a PRO in no time.
Giod job .. 👍👍👍👍

No the resistor limits current ant without it it will problaly burn the led
As usual, you are perfect. Thanks for sharing. ;-)
thanks buddy all your stuff is helpful
easy way to explain is visual presentation, good job bro!
Thank you
Like it when you include the schmatic.. with time to view them robert
Muy bien gracias
Mulțumesc frumos pentru aceste îmi place foarte mult.
Wonder how long the Transistor and LED will last with a relay coil and no flywheel back-EMF diode?
Can you explain how the circuits works? Or only you copy the circuits
Ur so cool. What model of the soldering iron u use for this project?? Tks
Great video but it would be useful to list components at end of video.
I agree
gibt es auch schaltungen für smd LED 0402 ?
That was great and simple , but I didn't got the reason of the relay (6 volt) you showed us in the first circuit, simply because you didn't use it at all? Or it was just a fault?

Very nice..simple circuit
Thank you
Very interesting ... please let me know..how make with .. when room lights on led will lights up and keep waiting 1or 2 minute and want to led off..
Hello bhai mere pass sony car speaker 2 hai to mai ise direct bettri mai lagadu to chale ga kya
Nice to meet you my friend, your work is amazing, I like your work, keep it up

Wow..... number 3 is an awesome
I hope you buy your BC547 in bags of 100, because the first two circuits are transistor killer (if you add the optional relay to the first one).
Cancion de Michael Jackson we are the world
Sir bc547 ka leya minimum kitna volt lagtha ha.
All video is super. Sir ji
Can U explain in a video that how all these circuits works after connected to a battery
number 4: better using a laser instead of LED, for longer distances!
What LED do I need for Project 6?
Next pls can u show the CKT diagram 🙏🙏🙏
Ia it possible for making amplifier?
In which device's we can get bc547 transistors
I like your project of using of bc 547 resistance
Can add more LED for last circuit??
You can add in parallel
🤔🤨🧐💪👍🙌 super cool 🏋️
GOOD IDEAS👍
Very good vibes thanks Sir ji was just
Thank you🌷🌻🥀🌺🌹👍
1 Min ago and still not first Comment...
Good job 👍👍👌👌
Hi what,s the name of the music your playing from your cell phone?
My ldr is reacting only when I flash light at it. It doesn't work in the dark. is this normal?
Very nice videos
What do you use for a soldering iron?
60 watt soldering iron is best for soldering
U get a soldering kit online
In no.5 project you must remove your background music to listen your speaker loud test what is this tang na teng tang na teng.....
U learned from .....
Which engineering .....
This experiment are down on your own how did u learned...
सर गाड़ी में led लाईट लगाना चाहता हूं,एक पुराना किसान कम्पनी का टॉर्च है जिसमे 12v डीसी के द्वारा सर्किट बना कर लगाना है,कृपया मार्गदर्शन करे
friend .. you could make a circuit of airplane navigation lights to put models
Resistor kitne Om ka hai ji please ans
Well done
Vou fazer na fantasia do Homem de ferro do meu filho. Boa ideia.
Good video
Awesome!
Bien bon courage
Great video
It's NPN or PNP?
BC 548C, what does the letter C mean?
Circuit
how is it called the tool that you use to melt aluminium?
Hi the tool is called a soldering iron and the wire is a soldering wire not aluminum
I have a 24v 8.5 amp dc motor.. its take for run lot of current its mean ampier so I need to reduce my current cost also ..need run same speed.. pls give solution
Bc547 kaha say milay ga plz plz plz jawab do
kasi b shop sy mil jayega electronics npn transistor
01:30 very good, this circuit
The battery 18650 how many mAh?
What kind of soldering iron he used?
Good Job Bud^^
Thank you
So it should not be out of the question to come up with a burglar alarm that when a beam of light is broken turns off an electromagnet and allows a door to slam shut..... how about it?
