hi there. i know this video is a bit old, hope you see this question though. i have this plasma ball and it is interfering wity my led wifi clock that is sitting on the same metal shelf. is there a way i can block the interference? i only have this shelf and they both look cool lit up. thanks in advance.
Honestly Tim I was just thinking the other day as to how effective is this shielding on this control cable, your demo is just spot on lol...oh and i seriously need a scope like that.. thanks tim
Yes when we stumbled across it in the how a plasma ball works video, I knew it would make a good example. It took me a few months after that to come up with how to use it. I'm going to try using "Dr. G"s suggestion of a ferrite core and see what it does to suppress the noise.
No, the shielding will prevent electrical noise from being transferred from one wire to another but your drives are likely inducing harmonics onto the incoming line
It depends on the application. There are some good articles out there if you google but the rough answer is if it is instrumentation and you want to keep noise out of the cable...one end, if it is a VFD cable and you want to keep the noise in the cable, both ends. But there are some other details that are worth reading about.
Hello sir. I am from India and following your channel for quite long. Is there any possibility to ship your products to India? I couldn't find the information anywhere on ur website. I have already sent u an email regarding this.
No, without being connected to ground on at least one end, they do nothing. I'm working on some videos to explain this better but as we show in this video, moving magnetic fields will induce current into a wire. The point of the shielded cable is to "sink" that induced current to ground before the magnetic field passes through the control wire. twcontrols.com/lessons/how-magnets-produce-electricity-using-a-magnet-and-coil-of-wire-stem-with-tim
Hey guys. One of my mental blocks is not understanding how the simplest shielded cable works. So the outer sheath stops noise getting to the signal carrying core...okay...that's fine if we consider conventional current flow, but with electron flow being equally valid, then the outer sheath is exposed to all the emfs, so from that viewpoint it ain't happening! Put me out of misery and I'll buy you a coffee.
Super. I'm going use this in my classes! I also show noise with a simple
I will have to see how the ferrite core reacts with the plasma ball. I will let you know what I find.
I love your guys' channel. Very helpful from simple concepts to complex.
Great to hear Ryan!
Great explanation and neat fun with the plasma ball. Thanks for sharing. Keep on having fun learning. LOVE.

Probably not is a way that would be visually pleasing. Grounding the shelf and putting metal in between them may help.

@@TimWilborne looking forward to more of your educational videos.
I was looking for a graphic Explanation of what is electrical noise. It's interesting ur video but hopefully make a video explaining electrical noise.
Thank you, well said.
Thanks very useful information 👍
Glad it was helpful!
Hi Tim,
Do we need to turn on the power supply to plasma ball for this experiment?
Can you tell me the name of the oscilloscope you were using
Yes, you must turn it on
Thank you
You're welcome
Hey, Your son is so smart and cute.
Could we use shielded cable to reduce harmonic of ac drives rather than Sinewave filter? Pls reply. from India
No, the shielding will prevent electrical noise from being transferred from one wire to another but your drives are likely inducing harmonics onto the incoming line
@@TimWilborneok thanks, shielded cable has to be earthed at both ends or only one end?

@@TimWilborne Thanks a lot, you are a gem man.🙏
You are welcome
Thanx ❤ from india
Most welcome! Thanks for watching!

No, we don't currently have any shipping options to India.
Good 👍
Thanks
So it’s simply not enough just to run that type of wire and cut off all that off on the ends?
No, without being connected to ground on at least one end, they do nothing.

Good work with your sun
Yes, thank you
