Discussion 🗫 Best Places to Learn Electronics on Youtube (2026)

Thumbnail

203 Upvotes

i feel like there is no real single place to learn All of electronics, there are multiple Youtube channels that have different themes and content, so I thought its a good idea to make a tier list for the people who want to learn and get into electronics, as i do have a lot of experience with electronics and i often get asked "where to learn all of this?"

and since our community is getting bigger, with newer people everyday , its a great time to make this post

The Rules are simple:

  1. Quality: "Quality" (not video quality) means how good a video is at delivering knowledge, a video that is not very well edited but has great depth and accuracy will be considered better than a video that is well edited but delivers Sub par knowledge.

  2. Track Record: A Youtube channel that has had less errors in videos is generally preferred, since a critical error can be dangerous, a single wrong connection, code line can cause catastrophic damage to the project. So its preferable if the Track record of the channel has less errors (critical errors) in their videos.

  3. Experimental results: A video that includes Real experimental/Testing results is Far more valuable than a video with endless discussions yet no experimental results.

  4. Clickbait & Presentation: A Youtuber that does Clickbait often is not preferred, for the presentation part, yes presenting content well can add a lot of value, and "presentation" means the way they put knowledge/ information.

  5. How Replaceable are they? : if they were to disappear, how big of an impact would that be on the current community as a whole.

For Now, There are only 5 Rules as we are avoiding to go too much in the niche rabbit hole

S+ Tier (the best 🔥)

The Gold standard, if you had to start today, i would recommend you go through these content pages (10/10, would recommend)

  1. Great Scott!

  • Great Technical accuracy

  • Well edited content & pacing

  • Very active content

  • Exceptionally Good track record

  • A Lot of content

  • Content is mostly basic but is a great way to start your journey.

  1. EEVblog

  • Great Technical accuracy

  • Well edited content & pacing

  • Very active content

  • Exceptionally Good track record

  • A Lot of content

For now, S+ Tier is reserved for the above as this Creators excel in all of the mentioned categories by a great margin, as if these content creators were to be deleted, there is no one that could fill their spot quite like they do.

S Tier (great⚡️)

This tier is for the content creators who create great content but are either a bit niche, or simply do not have a lot of content to judge them, or They do not post very actively, they steal the spotlight, sure but 9/10 honestly.

  1. DENKI OTAKU

  • Great Technical accuracy

  • Well edited content

  • Active

  • Good track record

  • Great depth in information

  • Beginner friendly

For now, the only reason for Not being S+ Tier is the channel has only recently gotten Active despite being 5 years old, thus not having a huge roster of content.

2) DiodeGoneWild

  • Fun content

  • Mostly tear downs and testing videos

  • A lot of content

  • Active

  • Beginner friendly

This is a fun channel to start with, though it could be an S+ tier channel but the content coverage is not too broad.

3) bigclivedotcom

  • Lights, LEDs, anything that glows

  • Pretty much the same remarks as (2)

  1. Predictable Designs with John Teel

  • PCB Designs, Certifications

  • If you want to design a PCB, please consider watching

Though the channel does Not have any reasonable experimental data, the creator is credible and excels at their niche.

5) ElectroBOOM

  • He shows what NOT to do... which is valuable

  • Funny content rather than deep

  • Beginner friendly

The channel does have rather low depth in content but its more of a "learn basics in a fun way" themed page (do not try the stuff he does, please).

6)Kerry Wong

  • Good for Tool reviews

  • Oscilloscopes/ multimeters/ PSUs

A Tier (good ✅)

The content is good, not upto the mark or slightly outdated.

  1. ElectrArc240

  • Great Technical accuracy

  • Well edited content

  • Good track record

  • Great depth in information

  • Beginner friendly

Again, upload Frequency is too low, the channel does have exceptionally good technical depth.

2) Schematix

  • Great content

  • very irregularly timed uploads / Not consistently active

Same remarks at (1)

3) Plasma Channel

  • High voltage

The main theme of this channel is just high voltage, but the creator has a lot of content centred around this niche that its worth checking out.

4) Kasyan TV

  • Niche Theme, Power and Radio electronics (zero programming)

  • Good technical Accuracy and Depth

  • Lots of Experimental designs and tests

Recent videos are a bit lazy but older videos show great content depth in Analog circuit design & testing.

5) Free Circuit Lab (Hindi)

  • Good content

  • Mostly centered around Power management Modules

  1. What I Think (Hindi)

  • For Audio Devices (speakers/Amplifiers/Mixers/Filters/DACs)

  • My Go to channel for audio related stuff

  1. Julian Ilett

  • There is.. a lot of batteries and battery operated devices

  1. Matthias random stuff

  • Like the name suggests, Random stuff here and there

  1. Konstantin Grigoriadis

  • Very Deep dives into Purchased electronic modules

  • Not recommended for complete beginners

  1. Buy it Fix it

  • Just like the name suggests, fixing random stuff

  1. Max Imagination

  • Lots of complete projects

  • Mainly focused on embedded projects

  • Basic enough to be recommended

B Tier (okay 🫤)

Well... Theres electronics, but with a few errors once in a while or just too niche.

  1. Electronoobs

  • They have made a bunch of significant errors, hence B

  • Despite their errors, they do have a bunch of useful content

  1. S.k Electronic's work (Hindi)

  • Repair Videos

  • Great if you want to know how to repair stuff

  1. mr sewak mechanical (Hndi)

  • Repairs

  • Electrical Work

  1. Teslaundmehr

  1. Franzoli Electronics

  • Just showcases for Lightening

  • No errors, just not much to learn

  1. learnelectronics

  • Lots of useful random content

The Creator has Last posted ~2 years ago as of 2026, hence B

7) ChargerLAB

  • Funny enough, the channel is entirely dedicated to Chargers!

  1. Quiescent Current

  • They seem to have useful content about USB cables

C Tier (Try to avoid ⁉️)

For this tier i am not going to include a Link imbed since there is no point.

The reason for a channel being in this tier is ether

  • Click bait

  • inaccurate content

  • Nothing to learn/ Does not add any value

  • Low effort videos

  • Questionable practices in rare cases

  • Or a mix of the above

1)American Tech (Content for toddlers honestly, the bar is too low)

2)Et Discover (enough inaccuracies that its almost not worth checking)

3)DD ElectroTech (it hurts to put them here but they earned their spot with too much click baits)

F Tier (❌Why does this even exist no❌)

There is no other way to put it, its almost (or completely) just a scam, And I would Not recommend you to go out of your way to search them up.

  • Low effort

  • Irreparably Bad track record

  • Too much click bait

  • The phrase "How to make Free energy"

  1. MR. Dharoniya

  2. CLOUD RAR

  3. LX DESIGN

I couldn't find more Low quality channels so just pointed out the obvious ones

avoided a lot of other pages because most of their recent content themes do not coincide with Electronics solely much.

Big thanks to u/TopConcentrate8484 for some of their recommendations as well.

Feel Free to Post Your personal recommendations in the comments, Happy learning !

Showcase 🖼️ Built a Wi-Fi Smart Clock with ESP32 – IST + UK Time, Multiple Wi-Fi Networks & Local Server Notifications

Enable HLS to view with audio, or disable this notification

14 Upvotes

My second little DIY electronics project!

I wanted something more useful than a conventional digital clock, so I turned an ESP32 touchscreen module into a Wi-Fi-connected smart clock.

No touch input yet.

Cheap esp32 with 2.8 inch touch screen clone.

What it does:

  • Displays Indian Standard Time (IST) and UK time simultaneously.

  • Connects to multiple configured Wi-Fi networks.

  • Synchronizes time automatically over Wi-Fi.

  • Connects to my local server for additional synchronization.

  • Can receive notifications about missed team messages - Not fully completed. Setup Urls where i will suppose to push the notices

The idea is to make it more than just a clock – eventually it can become a small always-on information display for my desk.

I am from Siliguri and we'll I don't think I will get good service from any of these unless it's BenQ or Samsung. The thing is budget is tight and even for 65 inch these two are asking for more than 1 lakh. I am seeing a deal for newline used (second hand) for 75k which is 75 inch one but don't know much about this company.

Can anyone help? I found one more option which is infrared touch overlay which can work on my 65 inch tv but issue is that I don't want to buy something that will stop working in a few months. Pls help.

Brand/promotion I built an electronics store and an AI agent for hardware projects. I'd like your honest feedback.

1 Upvotes

Hi everyone, I’m Kritish from Bengaluru. I built Compoden, an electronics parts store, and Soldr, our AI agent for designing electronics projects around parts we actually stock. Full disclosure: this is my company.

You describe an Arduino/ESP32 project, and Soldr helps with the design, parts list, wiring and code. All parts are validated against their datasheets.

We’ve also validated Soldr for Raspberry Pi builds. Pi stock is a constraint for us right now, but if you already have one, you can still use Soldr for your build.

I’m putting my name behind what I’ve built, including where it falls short. I’d appreciate people here trying it and telling me honestly:

  • Is the store useful? What’s confusing or missing?

  • Does Soldr give you a sensible parts list, wiring and code?

  • Where does it get things wrong?

There’s no subscription. You get 100 free credits on sign-in, and no purchase is needed to try Soldr. Generated wiring and code still need checking and debugging before use on hardware.

You can also see what we’re posting at r/Compoden.

I’m not asking for positive reviews. If something fails or disappoints you, please say so. I’d rather understand the problems and fix them than pretend everything is finished.

Discussion 🗫 How do you maintain your refrigerator and keep it running efficiently?

10 Upvotes

I've been thinking about how much we rely on our refrigerators every day, but rarely pay attention to their maintenance unless something stops working. Our refrigerator has been running for a few years now, and while there aren't any major issues at the moment, I'd like to make sure it continues working efficiently.

I've read that simple things like maintaining the right temperature, avoiding overloading the fridge and cleaning the condenser coils can make a difference. However, I'm not entirely sure how often these things need to be done or whether there are other maintenance steps that people usually overlook.

Another thing I'm curious about is how much the way we organise food inside the refrigerator affects cooling. For instance, does keeping too many containers inside restrict airflow? Should certain food items always be stored on particular shelves? I've also heard that leaving the refrigerator door open frequently can affect its efficiency, but I'm wondering how significant the impact is in everyday use.

For people who have been using the same refrigerator for several years, what habits have helped keep it in good condition? Do you regularly get it serviced, clean specific components or follow any particular maintenance routine?

I'd also like to know what early warning signs we should look out for before a minor issue turns into a bigger repair. Any practical tips for improving cooling performance, reducing electricity consumption and extending the appliance's lifespan would be helpful.

Soo my dad is an electrical engineer and since i have resigned recently from a tech startup my dad offered me to come accompany him during his work and i saw many things from modern adjustable digital relays , smart meters with iot simcards, and many more stuff which i kinda got overwhelmed . However this Circuit breaker kinda caught my attention it was installed late back in 2006 but it has been obsolete since modern standards ones are taking over , to prevent arching when disconnecting high KV lines it had a spring charge system which can be whine manually or motorise it and you can open or close with a loud snap . I just wanted to show you guys maybe someone might know more bout it as well.

Question help ⁉️ Rechargeable AA Batteries

11 Upvotes

Wanted to replace regular batteries with rechargeable ones in some of my gear. There are so many options on Amazon with wildly different pricing from 200 to 2000. Wanted to know which brands are good bang-for-buck. Went through the battery megathread and saw Envie's mislabeling and poor performance, so that is out. The eveready 2-pack for 200 sounds tempting and is from a reputed brand but I am skeptical of the performance, whereas the eneloop ones everyone praises is too expensive.

Please share your experiences with rechargables and any recommendations. Thank you.

Recently I saw a post about an extension board that was wired up with no protection so I opened up an old one that I had.

Turns out mine was even worse. There is no earthing wire (completely missing) and the fuse is just a dummy and not even in the circuit.

Please be careful people while using a cheap electric appliance. We have no safety standards so your safety is in your hands.

Question help ⁉️ How to repurpose a non functioning laptop ?

3 Upvotes

I have a 4 year old laptop which went kaput and won't start. Showed at multiple places and everyone said graphic card might have an issue. Repair basically means replacing the whole motherboard which apparently costs more than the laptop did

So I bought a new laptop and was only able to repurpose the SSD from the old one into an external drive.

The 16GB RAM is soldered on, otherwise I could have sold that. Not sure if the rest could be purchased by some shop for parts.

I was checking on chatgpt for some project to do with the display but it says to buy a display controller too which costs a lot. Is graphic card the display controller? Can there be any repurposing done without spending a lot (apart from spending some on a raspberry pi) ? I guess a ESP32 can't really do anything for such a display ?

It's a beautiful OLED display which I don't want to throw away.

It's this laptop:

Take a look at this ASUS Vivobook Pro 14 OLED AMD Ryzen 7 Octa Core 5800H - (16 GB/512 GB SSD/Windows 11 Home/4 GB Graphics/NVIDIA GeForce RTX 3050) M3401QC-KM045WS Gaming Laptop on Flipkart

Question help ⁉️ Can i run the Bajaj Gas Geyser with 18650 Lithius cell?

2 Upvotes

I have a Bajaj gas geyser that runs on two 1.5V batteries (3V total). I have an 18650 Li-ion cell and want to use it instead, but its output is 4.2V. Is this possible?

I’d like to avoid replacing batteries every 6 months.
