DIY METAL DETECTOR, Gone Wrong and Right!!

YO! I'm still waiting to HEART a comment! in the meantime, ALUMAGNETIC FOREVER! Paramagnetic, diamagnetic or antimagnetic properties of non-ferromagnetic... sorry, ALUMAGNETIC metal are very week magnetic properties observable in DC fields, which I don't care about. They are overshadowed by MUCH greater Eddy Current magnetic forces in AC. ALUMAGNETIC focuses on great AC forces of whatever that is not ferromagnetic!

Does this count as one of electroboom’s hair-raising electrifying shocking adventures?

05:16: The core splits itself apart because the flux lines pass through each laminated layer. Since there is a gap between each layer, you end up having the said layers behave like like-oriented magnets, thus they repel each other

It’s crazy how smart Electroboom is but still keeps it funny with the fails and stuff.

I love how when I was a kid being fascinated by his knowledge in electronics and thinking he's a man of magic and now that I'm studying my bachelor's in electronics understanding everything he says and recognising circuits. When I look back I see I've grown a lot and will also be a magic man to future generations

The hobby shall heretofore be called "metal detectoring" and I will be taking no questions at this time.

Mehdi, you did a fantastic job, covering 2 types of metal detectors (energy theft and BFO) in just 20 minutes, with no loss of fingers or eyesight. Well done, and thanks for the shout-out. As for the cross-coupled transmitter, I've used that in a metal detector design (White's TRX) and did not use any bias resistors on the transistors. You should not need them. On the transformer plates, they push apart because the eddy current generated in each plate (across the thin cross-section) interacts with the coil's magnetic field to produce a force which is the cross-product of the two, and is perpendicular to both. This means that at the surfaces of the plates, the forces oppose each other and try to push the plates apart. Hard to explain in words, easy to illustrate. Any decent EM book explains it. A dangerously impressive example of this force can be found in coin shrinkers, where a sufficiently strong EM field creates enough radial force to literally shrink a coin. If you were to do a video on coin shrinkers, I would not dare to wager that you have 10 fingers at the end. Edit: I couldn't remember the name of the force so I had to look it up: Lorentz force, where F = J x B (cross product).

I like your sense of humor, your integrity in owning when you make a mistake and your selflessness in promoting other YouTube pages that also get it right. It shows you will always be about the facts

Finally some awesome proper electric design content we needed this Everybody love to understand how things works and how to make them using basic electrical knowledge

Sometimes, the explosions make you forget how intelligent this man is 🤓

Hello ElectroBOOM, I love your platform. I’ve been laughing and learning from you for a couple of years now. Please keep it up! Is there any chance of getting a schematic and materials list for this tutorial?

Comedic and electrical genius. A rare combination of talent.

For 4:56, due to the core having multiple individual pieces, each producing its own magnetic field in the same direction, it makes them repel each other. Maybe that's why core pieces are tightly stuck together to avoid vibration due to repelling.

15:49 Mehdi you made a Geiger counter 😂😂

You sir deserve your own Netflix series. I have been entertained all day watching your videos. You are genuinely likeable.

This has to be ElectroBoom's most challenging and satisfying project yet.

Mehdi, this was one of your best videos in a long time!!!! Is so amazing to see the electronic circuit forming before our eyes and see all the logic behind it and the reason for each component!!!! Do more content like this one

2:55 yum, high voltage

It's actually crazy how much this kind of field of work relates to music/sound design with basic waveforms. Even the terms used are the same. Math really does connect everything.

Never fail to get a chuckle from me multiple times every video. And I occasionally retain information i learn lol. Thanks Mehdi!
