My 30 year old microwave has that spinning fan thing but I haven't seen that on any newer machines

"And this is a fan." Thanks man.

That was some rocking white board animation. I like it.

"It will make future generation smarter by natural selection." Yes.

6:28 "...and this is a fan" Yes, finally something I understand

Turn on English subtitle at 4:07. Trust me !

My GE microwave from 2005 finally crapped out. At first kzfaq.infoUgkxO_Bc204MGjxDl87cOKcdgaRhzSqGmv_g I was unsure because I was looking for something with the exact same features. Found it with this one. Interior space cavity was large, but the outside was smaller than my old one. I love the one-button push for 1-6 minutes, and the 30 second add or 30 second start. and MOST IMPORTANTLY, I love how you can adjust the power level during cooking. The reviews said it could not be done, but this marked all the other boxes. and happy to say, it does. I can hit 1 minute start, and change the power level from 10 to 5, 30 seconds in, without interruption. my favorite feature!

0:18 how to get more words in an essay

"on the bright side it makes the next generation smarter by natural selection" i'm done

"On the bright side, it could help make the future generations smarter by natural selection" XD XD laughed so hard!

Fun fact: A Microwave oven in Dutch (my native language) is called a "Magnetron oven", named after the wave generating device.

He measured the speed of light using electromagnetic standing waves.

"This is called a magnatron, it is a device built upon the dark arts of electronics" I love this guy. The further I get into electrical engineering, the more I understand just how brilliant he is.

( @ 5:17 ) Now I get it, why my patients scream so much during their surgery, I always feel like I'm forgetting something. I'll keep this in my mind.

4:55 "unhealthy, concerning, probably going to blow up duuuuuuuu" w/ subtitles on 😂😂😂

4:52 I love how he patiently waits for an explanation

That box demonstration is the best!

Will LED lights up in microwave? The answer: Yes.

Hey, it's been 4 years and I've finally recovered after looking into the wave guide. Thnx a bunch.

6:20 ... SHAKE THE POLAR MOLECULES GENERATING ***MUCH*** HEAT....!!!! (...and this is a fan....)

*5:07* *Even when he isn't fixing / building stuff, he still manages to make stuff explode.*

9:00 your thermal image has a mustache...

Top notch talking skills! Absolutely love every second of every word you say, really enjoyable, funny and useful! Absolutely lost it at 8:19

Before 1 Mil: I can't decide how to celebrate After 1 Mil: Did you heard the tragedy of Darth Mehdi the Wise?

Please be EXTRA careful if you take the magnetron apart, as you could get Berylliosis from the Beryllium stored inside that "stick" pointing out. This is not a joke, breathing in Beryllium dust is extremely toxic.

There's a mustache in the seek camera :P

5:08 almost got a hart attack SERIOUSLY my breath ran out for a couple of seconds

Gimme da metta wait im 4 years to late

5:30 "Megatron. TRANSFORMEEEEEEEEEEEERS!!" xDDDDDD I fucking love this guy.

If you'd like to know anything more about megatro- *_TRANSFORMERSSSSSSS-_*

The stirrer is in older microwaves and was phased out because it never really worked that well. It was before they had a revolving plate, I know this because I recently got the chance to scrap some microwaves from the 70's or 80's (not sure what time period, but they had fake woodgrain so I'm pretty sure there were from those general era's).

One of my favorite channels on KZfaq. I like this guy a lot. If only there were more KZfaq channels that are popular more like this guy. Channels like king of random or whatever don't count.

Man... every school should have at least one of you -- kids would be far more engaged in learning about science.

2:29 I just love how he says: "Wow look at this!"

I remember warming up a sausage roll on a small plate that had metal etching on it. It didn't register with my brain at the time that is until I switched the microwave on. It was the most impressive fireworks display I've ever seen...needless to say I didn't eat the sausage roll. I had a sandwich instead.😂

Congrats! 4millions subs, please do what you have promised, present to us your whole team who works on your videos!

The natural selection part killed me ..... SO TRUE !

This was great! Can you do a debunking/explanation of cellphones causing cancer please? Just like you did for the free energy video

Man you don't fear electricity. You're a true engineer. ❤️ You're my inspiration

Little did he know that transformer would become such an important tool for making videos in the future

Man, this guy is so hairy he even has a thermostash!

"I dont really know what to do with the magnetron besides causing cancer"

Excellent idea for a demonstration! I'd only seen it done as a plate of chocolate chips (melted spots are hot spots) like the Engineer Guy's cheese demo in the linked video. The box made a 3D visualization! Neat!

Newly discovered, subscribed and upvoted for the G1 Megatron reference!

hook up enough lemons to jump start a car

6:28 And this is a fan

8:19 That's true!

"This transformer is my new pride and joy" hahaha

5:10 Always make sure your capacitors, especially massive ones in microwave ovens are discharged. Also, keep the short circuit on them for a while too.

One of my favourite things to salvage from an old microwave is the turntable motor. It works great as a hand crank generator and can generate up to 230 volts depending on how fast you crank it.

Hi boom i already in patreot to support your video. And im very glad everytime i watch your videos hahahah. Same feelings as here repairing and making everything that makes my feeling happy with electrics.

I am a big fan. Mehdi, Love your work

Do I want a Huge wave or a Micro wave?

I knew that you were gonna make a vid about microwawes when I stalked your liked vids list

I love the guy, hope he keeps the video's coming.

6:10 from now on I'll pronunce the "transformer" word like this, even in front of other people

how is this guy still alive? XD

You forgot the HIGH VOLTAGE capacitor in there......... I hate you for not discharging it using your eyeballs or something lol

I'm hoping for the thermal camera, unfortunately, I've just noticed that the video was 2 years ago ahaha. Hey bro I'm always amazed and learned from every video you've downloaded, keep the electrifying job you're so funny and smart at the same time. New subscriber here

EVERY video from this guy is great!!

hahaha, love it Mehdi, you are the best instructor and comedian. There's more to salvage on Microwave Ovens, there's the microswitches, the mains filter at the back on the top, see at 6:43, some relays on the main board. The fan blades can be used to stir water, even be used in a small dinghy with a powerful enough motor to drive the dinghy and can be used to provide air-flow at your soldering bench, if you are careful about wiring it up and protecting yourself from the mains (115 VAC or 230 VAC).

9:23 i searched for gold yet i found a gem!

OK.... i think you would be an excellent professor, the students would listen to you and learn while having fun ... many should learn from you.

This guys vids are entertaining and informative with the right amount of comedy

At 6:28 that would've been me... "This is a fan" 😂😂😂

You sir are hilarious. Never thought electronics could be so funny. That Natural selection joke was amazing.

Another amazing and interesting video...

Another way to fix the hot and cold spots is to make sure the plate is in the corner of the rotating part so there is no stationary part that has no way of getting affected by the waves.

Started watching these at work and had to turn on captions... and I must say bravo to that, ElectroBOOM even making the captions hilarious!! 4:50 "Unhealthy, concerning, probably going to blow up duuuuuuuuu" XD that sick microwave!!

Suggestion: Make a huge Tesla coil, wear a Faraday-cage-like suit and get shocked.

I don’t know how I found out about you just now 😂 where were you when I needed you for my Physics Exam last year

5:05 "You can see that the AC line enters from that corner, and feeds it-*POP*-YOOOW!!" 😂

5:02 - Hm, I hope you discharged the caps (or they have safety). 5:08 - Nevermind.

"And this is a fan." My god it's such a joy watching these videos.

8:04 - Welp. I'm pausing right here to go look directly into the Wave Guide before continuing watching the video. It sounds exciting!

Whenever I'm doing repairs or working on something electronic I have this guy playing in the background to get me in the mood to work

can you explain and make a circuit that can capture purely Back emf sparks? and save them the voltages stationary with maybe with an condensator, or shot back into an battery?

In my experiential physics classes in uni, we have talked about a lot of ways to calculate the speed of light, but only a crazy genius would do it using a microwave like that.

Your video gives me inspiration: Can I use a microwave for dirty soldering, even without Lötzinn (LANG=DE, tin-lead solder)? Melting the metal.

That pen part amazed me. I legit figured it rubbed the ink off

I love how he says so many complicated things, and then just points out the fan 😂!!

There is nothing better than laughing while learning. Well, maybe one thing. Thanks Electroboom. You're awsome!

I want my free thermal camera! great video, I like you're stuff.

You make boring things funny I love what you do I wish I was that good at something

Thanks for this really cool pseudo-3d visualisation of the heating pattern in a microwave! I'm a high school physics teacher and I was enthusiastic about doing the experiment to estimate the speed of light using a microwave and chocolate...until I discovered that it (usually) doesn't work. In fact, out of four microwave ovens I tried, I couldn't honestly say I got anything remotely resembling a regular "standing wave" pattern in the chocolate. Then I got my hands on a thermal camera like yours, and I heated up sheets of paper (instead of chocolate) and different heights in the oven (naturally without the rotation plate) and looked at the patterns. First - as you saw yourself in the video - the patterns are not exactly regular. Mine were usually even less pretty than the one you show in this video - and they changed a lot at different heights in the oven. I got suspicious of these experiments and found a paper that agrees: iopscience.iop.org/article/10.1088/0031-9120/49/4/419. They write about the c = lambda*freq method in the case of the microwave pattern: "But this is not correct. The distribution of an electric field in a 3D cavity is rather complicated and the idea of wave resonance in a one dimensional string simply cannot be applied to this case. (...)even in this very simplified case there is no observable distance between spots that are equal to 6 cm as it is predicted from the simple one dimensional model. So this method can provide only a very rough estimation of the speed of light." And that was my experience too. In the end, it seems more like a matter of luck whether or not spots that are about 6cm apart or not (I would say I even had trouble finding a single such pair!). I did this experiment in class using the pieces of paper, kind of like you did but in 2d - but made a point of explaining that the well-liked chocolate experiment couldn't reliably work, and people simply tended to see what they wanted to see. It reminded me of the episode where Lowell thought he saw an intricate canal network on the surface of Mars through his telescope! You also seem to find spots that are around 6 cm apart, and I'm just wondering about the casual comment you dropped about "looking for the spots that are closest together". Do you feel sure about that claim? After seeing the random patterns I saw myself using a thermal camera, I suspect it's impossible to know what the hot-spot separation will be, unless an exact simulation of the freq, waveguide, oven dimensions etc. is made in advance. Thoughts?

That thermal camera gives you a moustache!

Your Channel Is like a mix of the 8 bit guy and the AVGN, it's Just PERFECTION

Love your videos!

The stirrer is ONLY in ovens that do not have a rotating carousel plate. The rotating carousel design eliminated the need to the stirrer in smaller ovens. larger and commercial oven will have a stirrer and no rotating plates. For the magnetron tube to turn on you need more than just the 2Kv, you need an HV capacitor andan Hv diode. These will bring the voltage up and raise the amperage to the magnetron tube reaches resonance and start working. Also you need 6 volts for the cathode heater in the tube. This is the third winding on the MOT. Also a warning, The magnetron is made of beryllium ceramic and is VERY toxic so handle with care and do not break it.

Mehdi, calculate the golden ratio, using a very long series-parallel circuit of same-valued resistors! :D

“You need to know how microwaves work.” *Hits the camera with the microwave door*

This is my favorite electroboom video

I can't stop laughing at 9:36

7:56 Disclaimer, don't pause the video and keep watching until the end before taking this Darwin joke advice for serious.

09:00 that secret moustache only made visible by thermal imaging is next level MOVEMBER

you really make learning fun and interesting,,,,,thank you
