sunt fascinat de montajele dumneavoastra si de prezentarea lor, va multumesc !

[@stefan09ism]

I am fascinated by your montages and their presentation, thank you!

Welcome

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.

Bahut hi saandaar video thi 👍🏻

[@anoopsahal1202]

The led chaser is a work art !

[@peterjones3245]

What a delightful video and technique! Who needs circuit diagrams!

[@TheDagger55]

People who want a clear schematic, but ok I guess.

[@berk1738]

I need

[@evandrocarvalho4692]

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.

[@TechIdeasAG]

Thank you

[@inoemanunggal8588]

Continue 👌 👍👍👍👍

[@MaikeTech]

That's awesome. I tried 3 bc547 projects on my channel to see if it works.

[@sakibhossain7439]

Very helpful video. I like this type of video.

[@guillogarcia3711]

Excelente vídeo, muy buenas ideas, gracias.

[@KSelectric]

You have good soldering experience

[@kristofersozo464]

It would be great to see some schematics of these projects.

[@travellingwithharish3006]

Nice Experiments 👍Realy Creative video 🎉

[@FlowVirm]

I love you're series

[@newagerc5356]

Your board less circuits are elegant.

[@TechIdeasAG]

Thank you

[@nareshtechindia6780]

Very nice bro video good job

[@SatishKumar-pp4vt]

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?

[@techfort4970]

Good work, kindly explain the circuit in the description.

[@rociocausing6999]

I think it's better if there is schematic diagram for each project

[@bassambassam4782]

Thank you for wonderful video

[@kelumpriyanjana3747]

Very nice..simple circuit

[@TechIdeasAG]

Thank you

Awesome!

[@RahulGupta-zf5th]

All video is super. Sir ji

[@prasantadutta4293]

I really like the way u solder the components

[@ElectroProjects]

I agree with you

[@barymillien7066]

thanks buddy all your stuff is helpful

[@gregglasgow9432]

Really enjoy, Thanks. I learn a lot by simple projects.

[@TechIdeasAG]

Welcome

[@uthaungnyi1257]

I really like that.Thanks.😊

[@nidhindinesan2670]

Wow..... number 3 is an awesome

[@reidogarimpo1691]

Muito bom! Parabéns nota 10

[@TechIdeasAG]

Thank you

[@mrdovie47]

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) .

[@freddyvillegas4357]

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.

[@hackedapps794]

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

[@AmazingMJ07]

Very nice Really useful for me 👍♥

[@TechIdeasAG]

Thank you

[@inoemanunggal8588]

Giod job .. 👍👍👍👍

[@singingzone3056]

Nice projects

[@imranjameel3693]

Great video

[@HomeDronen]

Awesome 👍 stuff!

[@TechIdeasAG]

Thank you

[@alfikriafandi894]

GOOD IDEAS👍

[@djSouRay]

Ur so cool. What model of the soldering iron u use for this project?? Tks

[@comaravcs79]

Benefit work thanks

[@VijaySharma-vx5es]

Very good vibes thanks Sir ji was just

[@robertyoung9614]

Like it when you include the schmatic.. with time to view them robert

[@carlosmoreno-je4rz]

Muy bien gracias

[@alexandercreativechannel1831]

Cool!!!

[@nayanapatil2373]

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 🤞

[@vibhorkumar7788]

You have good soldering skills... Make a video on how to solder nicely like you.

[@cholomsury1548]

Yes I would like that too

[@jimruby9657]

Just watching this video has given me ideas on how to up my soldering mojo!

[@albertoponce8975]

best soldering melting point 330°C to 350°C (626°F to 662°F) and pre-paste

[@LuckyTrader5420]

Ya nice soldering

[@ocdtechtalk]

Practice. Get old trash electronics and desolder and resolder everything. You will be a PRO in no time.

[@thinkerszone1520]

Good stuff

[@robertjoseph1493]

I like your project of using of bc 547 resistance

[@michaellane4087]

Great video but it would be useful to list components at end of video.

[@ElectroProjects]

I agree

[@sivadasantv5913]

In first circuit, how to adjust the time of led glowing. I want 5 sec

[@ElectroProjects]

Hi you can do that using the same circuit by increasing the capacitance or put one more that type capacitor In parallel

[@mixvideobogra8941]

Nice

[@johndavid680]

Next pls can u show the CKT diagram 🙏🙏🙏

[@user-hj2ou5rz1w]

Thank you🌷🌻🥀🌺🌹👍

[@kailasbafna8397]

In which u used relay??

[@nishanhk8599]

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..

[@mavailve]

Thanks a for uploading this video. It has been a big help to me.

[@moiperso3716]

🤔🤨🧐💪👍🙌 super cool 🏋️

[@davepickering997]

Wonder how long the Transistor and LED will last with a relay coil and no flywheel back-EMF diode?

[@ranjitkumarjha3344]

Super bro

[@drssound5273]

Good job 👍👍👌👌

[@InsuranceandPAN]

Last project 10:50 minutes lo Led's 10 use cheyyocha

[@akkaouitv2625]

Bien bon courage

[@muhammadzahid705]

Good work

[@TechIdeasAG]

Thank you

[@phitrow]

7:28 Amplifier for or speacker 10W you need transistor 10W too! But is minimum.

[@saidagouar5119]

Bonjour, votre vidéo très intéressante, c'est l'électronique pratique, j'aime.

[@utsourceprojects9020]

Nice to meet you my friend, your work is amazing, I like your work, keep it up ✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔...........

[@ASHORSHEMAYA]

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

[@KellCDiniz]

@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.

[@ceasarabarollo9331]

wow so amizang

[@ashraf61]

As usual, you are perfect. Thanks for sharing. ;-)

[@superdau]

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).

[@lordmaro9177]

Cancion de Michael Jackson we are the world

[@kalyangautam7345]

Ia it possible for making amplifier?

[@creativegallery-thehomeofc5818]

Nice soldering

[@user-uk4mb4yj8s]

Молодец!!!!

[@clintestood5839]

Wounder full

[@mallashiva969]

Super thanks

[@Volkswagen_electronic]

Super

[@edmomsj]

friend .. you could make a circuit of airplane navigation lights to put models

[@transistorizedmx4163]

Can you explain how the circuits works? Or only you copy the circuits

[@gabriel-dz7zg]

number 4: better using a laser instead of LED, for longer distances!

[@prabhaspoloju5574]

Can U explain in a video that how all these circuits works after connected to a battery

[@hans429]

1 Min ago and still not first Comment...

[@arnaldofernandes9952]

Interesting.

[@ritaisabel8665]

Good

If u give voice over it will more grateful

[@samarthmagar6469]

Audio amplifier ke liye 5v chale ga kya?

[@HaleuangPasundan]

Mantap👍👍👍

[@johnnybuoy9551]

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?

[@giant163]

No the resistor limits current ant without it it will problaly burn the led

[@Mi-kb7bq]

Good video and Nice designe!

[@TechIdeasAG]

Thank you

[@peterschulz7201]

gibt es auch schaltungen für smd LED 0402 ?

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.....
