No it's not. It's not a computer pc. It's a shop project for the masses. Direct and simple. Don't you remember learning to solder in junior high? I use thin rosin core.
This is not a chaser, its a flasher. different LEDs draw different amounts of current and the tolerance of the resistors and capacitors varies so the flash duration will be different for every flasher set.
It works on the principle of an astable multivibrator, the chaser sequencially switches on and off of these 5 LEDs so that only one led will glow at any time.The led chaser ckt is completely different from astable multivibrator.
You should list the parts needed to build these projects. Have to remember that many viewers may not understand what you are doing. Also, narrate the video so people can understand why you doing this way instead of the other way.
This is rather taped, than soldered. I get eye cancer if i see that. Heating the transistors that long and again and again can destroy the transistor and also same on LED's.
Amigo, una pregunta, sabes porque los led rojos consumen mas? Los leds normales consumen entre 3.5 y 3.6 y los rojos 3.7 o 3.75v o es un problema mío? Jajaja muy buen video (me volví loco cuando dejaste todas las patas tan cortas, gemeral mente dejo todo lo mas separado posible jaja ^.^)
As per theory, one given LED should stay ON for 1 sec (T=RC) before the next transistor is turned ON. The LED stays ON for a sec but the next transistor gets switched before the discharge cycle of the preceding capacitor-resistor pair is complete. Hence the randomness. The positioning of the 100K resistor and corresponding 10uF capacitor needs to be changed
No knowledge how to solder correctly. No idea to show specifics in LED connectors (anode/cathode) or the polarity of ElCos. The effect looks nice, but in terms of teaching this vid is awfull.
Ydalir Ullrsson the polarity of the led is the flat spot on a 2 pin led is negative. A 3 pin usually the middle is common. A 4 pin you might want to look inside the plastic cover and google an image diagram. The transistor google an image diagram and find the flat spot, and the line thing on the image. The soldering should be just whack it on an uneven surface, and smooth it on a metal pad. Its called “research” go look it up.
100% spot on i can't even follow his video its that's bad the way he's put this video together one clip the wire is correct and the next clip the wire is on the wrong side
Interesting circuit...but... if you're going to do a video like this, you should 'explain' the operation of it... with either on-screen text or verbally... background music like this is for 'magic tricks' NOT any kind of 'tutorial'..... and if it's a tutorial of 'construction' techniques, it's very poor indeed... I will ask a question though... if you're using electrolytic caps... do they become reversed biased at any point of the oscillation?? Put a voltmeter on the cap to see if the voltage reverses.... and if so, you should be using 'non-polarized' caps... see ya
Not surprised....he probably thinks he knows something about electronics too.... now with a channel name of 'American Tech'.... maybe he's a money scammer too...see ya
I do not comprehend how you guys select what you need to use. Even when I read up on basics, I just don't gain any insight. The chasing sequence was neat, but, out of sync. How would you guarantee a true chasing sequence. I guess I have to go to school big time before I start making my own light effects. Thanks
great video bro ! i hate bread boards too. i just use wire wrap tool cus its faster and easier to make changes. by the way you can raise the voltage to make it blink faster.
TBH I have no idea how drag-soldering is relevant to non-PCB joints, but soldering without any flux is a bad idea (yeah, and flux-core solder is there just to help your iron's tip remain well-tinned - it should not be taken as a replacement for the actual flux).
Suggest you find an "Elmer"and learn all the things you are doing wrong, your projects will work better, last longer and you will actually have more fun.
this is NOT a chaser, just close to it. minor differences in the caps/resistors make it almost psuedo random and things like temperature can affect that. BTW a $0.05 perf board would make this 1000x better looking and likely make it work at least 10x better [more stable]
It is 2018 today so you can simply rig some SOT-23 atTiny to a shift register and achieve the same even with smooth cross-fading if you want to... or just rig it all to some smaller CPLD (which is an overkill however).
@@TheBypasser ATtiny ? Means first learn C or C++ then download a compiler then buy a programming kit and then write source codes and then connect a 74ls series shift register just for a simple chaser....? Lol
470 Ohms = yellow violet brown 100 kohms = brown black yellow Why you need 2W resistors for the LED's? Only 0,5W dropping-resistor's are needed for the LED's and 0,25W can be used for the Base-resistor's of the Transistors. Normally you have to look at the LED-Datasheets (Forward Voltage- and current) to calculate the proper values of the resistors.
@@djblackarrow Sorry but I think you and the other guy above did not understand. I was talking about what he shows not what was needed. He shows a resistor of 46 ohms and wrote 470 on the screen. Shows a resistor of 60 ohms and wrote 100. And about the 2w I think those were resistors of 2w because of the size and thickness, not that was needed. I normally use low power resistors for LEDs they are much smaller than those. And even with Transistors, I use resistors of 0,5W and it works well. And by the way, He was using 3.6V DC why those big resistors
It depends on the electrical Charakteristics of the used Transistors. You need the Datasheet(s) of the LED's you want to use and calculate the current the transistor has to be switched. To reduce Power-Dissipation at the transistor and the resistor, please connect the LED's in Series - not in parallel. My LED's: Kingbright / Luckylight Uf=3,3V If=0,02A. I connected 3 LED's in series, so the LED's need 9,9V at 0,02A. My Voltage Source is 12V. So you have to calculate 12V - 9,9V = 2,1V. This Voltage has to be dropped at the resistor. To calculate the value of the Resistor: 2,1V divided by 0,02A = 105 Ohm The string current stays at 0,02A and uses 0,24W in Total. The Power-loss at the Resistor is: 2,1V x 0,02A = 0,042W. When i connect these 3 LED's in parallel, the string current adds up to each LED. So you have to calculate 3 x 0,02A = 0,06A. That gives you a total Power of 0,72W. To calculate the resistor for each LED: (12V - 3,3V) = 8,7V / 0,02A = 435Ohms The voltage-drop at the resistors is 8,7V. So at the Resistors you have a power-loss of 0,174W. In my circuit 3 parallel connected LED's would use 0,48W more power as in series. The needed power supply current is 3-times higher and the resistors Power-loss is 4-times higher.
You can use every NPN Transistor who can handle the current of the LED. The Transistor's rated Collector-Emitter current has to be higher, than the forward current of the LED.
Cringe factor off the charts. Watching you bend the leads right on the case is so bad, you need to grip the lead with pliers to relieve the stress against the case, because bending them that way causes internal damage. Same with LEDs, you need precision needle nose pliers. And scissors to cut the leads? Very amateurish. And you burned yourself a few times!
If u search the code of the transistor you can see if that transistor is pnp or npn so u can use any transistor with same configuration of the transistor of the video
If you will do it the right way, you have to calculate the needed values of the dropping-resistors. It depends on your Supply-Voltage, the used LED's Forward Voltage- and current. Different colors of LED's = different electrical characteristics of the LED's.
Good job my friend keep it up ❤❤❤❤❤❤

Please use flux to solder. It's *painful* watching you solder.

Video is good, but turn down the volume level of the background music, or just get rid of it, it is annoyingly too loud
fine
There is no other sound besides the music so you could just mute it, dip shit
How many more LEDs can be added to each channel ? In series or parallels?
As per theory, one given LED should stay ON for 1 sec (T=RC) before the next transistor is turned ON. The LED stays ON for a sec but the next transistor gets switched before the discharge cycle of the preceding capacitor-resistor pair is complete. Hence the randomness.

He doesn’t explain anything nobody talks in there videos anymore for the beginner they would be lost that’s why suns are low

With the randomness of the flashing LEDs, it looks more like Christmas tree lights than a "CHARSER".
Sir we can use more led, capacitor, resistor, transistor for long.???
That's not a "chaser". It's just a random LED flasher. A chaser should have the LED's flashing in sequence one after the other.
