I have no idea what you're talking about, but I admire your knowledge and I like your accent and videos. I'm trying to "tap" a 16v power socket on a turntable, so I can run an LED strip from it, but it seemed to destroy the electronics.... unless I destroyed them by trying to solder a power jack off the LED circuit board. I'm going to try one more time, then probably use a 12v battery. That's the level of my electronics :D

Whenever I plug a component (like a TO-220) into a breadboard, I always use a pair of small needle-nosed pliers to bend the pins of the component 90 degrees first (on the pin axis), so that the component will slide nicely into the board (like a wire) without any damage to the component OR board--What do you think.

Interesting take on SCR control. What advantages would you say this rather involved method has over the original three or four component control circuit used most widely? You are a great teacher and lots of people are interested in this subject so I am curious why you did not also mention the simple way to control an SCR with a variable resistor, a fixed resistor , a capacitor and a diac ( The diac is optional) Thanks for a very interesting and informative channel.

Hey there Mr +GreatScott! Always love watching your videos. You seem to be having loads of fun :) Can I ask if you bought that variac from a spanish company called something like SATKIT or similar? Am thinking of picking up the 12amp / 3KVA version but was put off by the slightly lethal appearance. However you are not dead, so maybe it is not so bad :) Did you also use an isolation transformer? Should I get one to avoid being dead? They are very expensive :( Thanks for reading and keep on making awesome vids!

@jakelittle8098 8 лет назад

Nice!!!! I have a printer I tore down for project parts (HP LaserJet 1012). It has a circuit straight off of the mains voltage (120v/60Hz) that consists of an inductor-HV film capacitor-Triac (BCR8PM) w/ Opticouple (3SD21)-feeding into a 24vDC/240vAC 10A Relay. The circuit feeds the heating elements of the "ink setting" system. I've been scribbling all over this PCB trying to figure out how this 'triac thing' works....Then, in a break from my frustrations...you read my mind, mid project, and I got schooled ;)

@marcushoutzager6225 5 лет назад

Hi GreatScott! Do you happen to know any good circuits that use triacs or SSRs without overheat problems? Maybe with loads around 1200Ws?

@leonamferreira8053 5 лет назад

This is a really mind blowing video!! Thanks so much for sharing this valuable knowledge! Im using your idea into my final course work. By the way, one thing I would suggest is to change the map function on your code. The potentiometer is being mapped from 0 to 10,000 microseconds (which corresponds to 1 period of the 60 Hz signal), but Arduino nano is getting the zeros in 120 Hz, because you rectified the AC signal. Then, instead of mapping from 0 to 10,000 I would suggest you to do it from 0 to 8333. That helped me here :)

@leonamferreira8053 5 лет назад

I've modified the code again. I mapped from 1000 to 8000. I've put 1000 because arduino needs to wait the 1ms pulse from the digital input 2 and decrease to 8000 to avoid crossing the next pulse.

Hey! Can you please mention the three Thyristors shown at 0:24? Are those good for general experimentation to learn about these components? An you also mention some general Triacs in those packages for the same purpose? I know TO-92 package doesnt make sense for such components but I am obsessed with it!

Of course when I realized this, my mouse traveled at 99% light speed towards the like button, and the table broke from the force of the left click when the mouse was over the like button. I proudly saw the dislike counter go down 1 and the like counter go up 1. You make good videos!

Hey I was trying a similar Circuit for making AC dimmer for 220V using BTA 12 TRIACs, the problem is when I use if for controlling fan speed it controls its speed but their is a humming noise. What could be the reason , do I need a snubber circuit

@adamcowlam5527 8 лет назад

Hi, I don't understand what you are using the optocoupler for, I did here that the higher the voltage on the input, the more infra red light the LED emitted an therefore increasing the voltage on the output through a phototransistor but how does that then create a voltage burst at every zero point of every half wave? Thanks

@AndrewCubacub 7 лет назад

What was your course or program when you were just college? That would help me to choose in the future.

@ashish6633 5 лет назад

Really nice videos, keep up the good work. I have just one small question, by switching the triac what do we actually control. i.e. the AC voltage or the AC current. I mean to as if i monitor the AC Waveform across the load then will i get to see a clean sine wave?

@coolaj86 5 лет назад

The Triac behaves like a full-bridge rectifier made from diodes. It is either fully on or fully off and does not limit voltage or current in the way that a Transistor (MOSFET) would. Instead, the current is controlled by waiting to activate the gate of the Triac until some number of milliseconds after the ac wave crosses the zero point. The full 60hz wave is 16.67ms wide, so each half is 8.33ms wide. He controls power delivery by adjusting the delay between 1 and 10ms before activating (closing) the Triac, which results in very crude waveforms which either begin partway into each half of the 60hz signal (1-8ms delay) or completely skips one half of the wave altogether, and a little into the next (10ms delay). As such using either a 4ms or 9ms delay is about the same in terms of getting half of the power, but using a 7ms delay would be far, far less. If you want a clean sine wave then you'd want to use a linear regulator (MOSFET) instead of a Triac. It would be less efficient for some uses and more efficient for others.
