Body's resistance is forming the gate resistor, drain source current is limited by the resistor already connected, flow of drain current lights up the LED.

Excellent Pat, but I have a remark 70 percent of your life as a programmer has been wasted because you don't use windows

I would say there are still many topics you should discuss. The video was outstanding and very clear. Thank you and more please

Nice video,thanks :)

awesome

Informative but missing the point! (Or am I?) Suppose there is a hundred watt bulb instead of an LED. It will get 20 milliamps and will not even glow until the "short" is reflected back and more current can flow. What if it isn't a 50 ohm transmission line... (like if the wires aren't close to each other). Then you don't even get 20 milliamps!

Thar works with a bjt as well

I watched all 5 videos, but I was in incognito mode just came back sign-in to leave a like and sub. Thank you very much for such amazing content, really appreciable even after 5 years.

Greetings from Türkiye. Thank you for sharing your experiences and knowledge.

Pi is more for server like purposes

MOSFET faster than BJT... Nah... 😂

arent BJTs faster?

Really cool stuff.

Damn straight! Anything worth doing, is worth making at least four major revisions for. In all honesty, I hate breadboards with a passion.

Ah they rotated my LDO and due to high power board and limit for 10A this just burned my board xDD

BJTs are generally much faster than FETs ... did you even research?

Like it. Nice driver

I guess there was no explanation regarding extracting (CM , DM ) information about mathematical operations on waveforms using an oscilloscope instead of D.M.R.N`s. The system was even assembled in 1:33:08 after all GJ!

What is going on around the 40:00 minute mark? ( ua-cam.com/video/SM76F537vjc/v-deo.htmlsi=XtDe7qTBd9qpJ2TA&t=2400 ) As best I can tell, there is a differential pair that is jumping over a bunch of gaps, and a parallel signal from the other side of the ground plane is causing crosstalk. But why would you put those gaps in the plane in the first place? It isn't for a via, or neither track would be there. If you're pulling the plane away/using a hatched plane for greater impedance, then why not do that on the rest of the track, too? (e.g. why first go South and circle around on solid areas? And why does the other signal layer run over those cutouts, but over (under?) solid ground to the left?) And would coupling be a problem even with the ground plane, since the plane is pretty thin, and both layers would be using it for return current at the same time?

Thankyou Robert and Pat for this amazing and wonderful session.

Beware that there are both enhancement mode and depletion mode FETs, so be sure to check the data-sheet before ordering any.

Metal Oxide Semiconductor - Field Effect Transistor.

Im using arduino nano 33 iot and ble boards

1:11:18 so this is where the title pic comes from. I may have missed it prior, but does this mean that in CMOS we have to group nMOSFET and pMOSFET ? I saw some die shots of RCA 1802 and it had a lot of rings. But as I understand each ring connected to Vdd or Vss is made of metal and is connected to doped silicon which completely encapsulates the transistor almost like a Faraday cage? I thought that the substrate would have one of the dopings, and the opposite doping would slide in from the source or drain. Is this to preven dirty effects at the end of these small width transistors? Power transistors can fold the gate inside this ring. I should probably google clock circuits. Also the amplifiers in front of the PLA of the 65C02 probably need power and output pins.

When +ve voltage applied to the gate then capacitance created on gate and then MOSFET is turned on and it stills on if you remove gate supply, if you apply -ve voltage to the gate then this created capacitance is disappeared and MOSFET turned off.

Raspberry pi pico: _sad non computer noises_

Nice video, Do you know where we can build our chip with multiple wafer DIYer and low cost ?$300 is expensive for DIY. thanks :)

In this case body act's as a resistor which allow very small current to flow through the body to gate of MOSFET which opens up the switch

Wow! Cool! I didn't get any of that though.

1) how did any current flow through you if that battery has like 9 volts 2) how did it proceed to glow when you let go of the thing

Hi...thanks for this tip. Do you use flux when removing the solder?

What is the difference between an EMC filter and a basic filter ?

Excellent video. Great presentation from Thomas and super helpful questions from Robert. I've learned something about EMC. Thank you.

Very confused I didn't get what you are trying to explain . I checked the comments of the other people they seems to don't understand either. Try too make it short and understandable.

I cannot explain how this circuit works. Why gate only charged via human body, and not gets charged by electromagnetic fields around? There should be plenty from mains around, for example, and that cable connected to gate works like antenna.

Nice and interesting presentation! Thx for sharing!

64 dollars "This not very expensive"... Bro, give me 64 dollars just for nothing in this case

22:00

great video, I hope you make me one for common mode soon

Funny you used a video from a windmill from neg micron it was a windmill company near my city before Vestas took it over after bankrupt

Great! I vote for common mode too

Unfortunately very rarely do manufacturers of ceramic caps talk about ESR on datasheets... how are we supposed to know this witchcraft 😊

Could someone please explain about the resistance and work perform and the current used up by the LED, to the return line, shouldn't after the LED the voltage to be less???

Displacement current through my prayers 🙏🏾 and the transmission to the Devine is instantly. This proves the communication from person to person mentally and that of the rest of the universe. This is how i take it, because this principle must be a result of of law that already existed and exist and we try to understand that and make use of the principle. This actually proves what maybe known as psychic phenomena✊🏾🤔👍🏾🗝️🏆🏆🏆🏆🏆

Perfection ✊🏾

interesting topic thanks!

i didn't understand well the video. I don't know if the guest is too smart and thinks other people know what's going on so he didn't explain or he's not good at explaining things. i also notice robert always ask so what's the solution or what should we do in that case hh If he didn't ask those question the guest will not answer at all hh. but good video anyway. thanks

Robert, I would try to let your guest follow his track a bit longer before you intervene with questions. Nevertheless liked the video very much.

Great video! I was curious of the rf wallpaper but couldn’t find it on Thomas web site. Can you please post a link. Thanks!
