Took apart an old satellite tv receiver recently and discovered it has what I can only assume is a number of PCB inductors: little circular spirals near power circuitry right where I'd expect to see a more traditionally-formed inductor. Was definitely an "oh cool I bet that's an inductor!" moment.

Well darn, that makes sense! I love these little videos!

I learn more about electronics by watching this guy's short videos than from everyone else's long videos.

More videos on inductors please

These videos are really good! Well presented, concise and nice topic choice.

Whenever I hear micro-henries, I think of the mini ash clones from Army of Darkness :)

I love inductors!

your videos are informative and clear, lovely, please keep pumping those gems

You deserve a subscribe with this good explanation

I love this high-quality content!

I needed a ferrite core inductor, so I decided to make one, I hope a cat will work in place of a ferrate!

Love these videos, and especially love the music in this one!

Awesome 🥳

I need those measurement tweezers! 😮

sooooo, if i when my amplifier is conected to a device that has too much background noise, the inductor whould fix it if i put it on the input side?

Should check for shield breaks in your input guitar lead wire. In your amplifier inspect the shield's connection, is the terminal connector lugs loose, shielding broken along the way to the plug at the input port on the guitar. Is the input port on the guitar loose, dirty, dull in color. Back in the amplifier, was there any modifications done that allowed the grounding terminal of the shield (aka foil) to be not attached to the factory designated ground terminal. You want absolutely near zero potential between the shield on the lead wire and chassis body. Potential difference though small translates to noise, it goes through differential amplifiers, that amplifies the intelligent signal. All grounding, even on the power to run the amplifier unit must be checked, cleaned and tighten and place exactly where the factory designates ground. If there is a hum in the back ground and all checks on the above description is good, check components in power supply : swollen capacitor, loose connections via bad solder, leaky capacitors like a dark dried glue pooled on the bread board. If not the tubes maybe noisy in the power supply or the drivers push pull on the speaker.

Smooth signals haha

Does anybody know the title of the soundtrack?

What is this Pen called??

Shmoove. :3

Do you have a video explaining how to use a oscilloscope? Seen several people on KZread with them butthey only use them without explaining. Are they like a multimeter for frequency?

Oscilloscopes are used to measure AC voltage signals.

So you are essentially correct.

Oscilloscopes measure signals in the time domain, i.e how a voltage varies with respect to time. They can measure DC or AC voltages, but they usually have much lower resolution than a digital multimeter so it wouldn't be the first tool you'd go for to measure a DC voltage if you wanted precision.

this really used plastic as a Isolator this will work . I tried everything with my copper wire but bruh.

Is it a magnetic field or an electromagnetic field?

Electromagnetic

That got my attention too, he said electromagnetic, but it's just a magnetic field
