Perfection is not required Paul. You're doing fine. A lot of people find you presentations quite informative and helpful. Thumbs up!
I concur!
You need to check your script? I think that guy needs to check his attitude!
Ignore the trolls Paul, they have nothing better to do.... Thanks for what you do!
this is where your channel really excels and why i keep coming back. thanks, Paul
You speak very fine on the explanations of the circuits your working on which have been very helpful. I like to see him do half of what your doing. Keep up the fine work your doing.
Exactly mate!
Agreed!
LLAP
I like the way you do your videos, not overly edited to try to make it look and sound perfect. Makes me feel like I am there looking over your shoulder and explained in a way that makes sense to me where others have failed. That's why Paul is one of only two channels that I subscribe to on Patreon.
Stay safe and happy holidays to you and all who watch this channel.
Love this series. It took me a while to figure them out but nice to finally have a really clear explanation.
Me too, I have wanted to do this for a long time for learning purposes.
Nice handmade inductor!
I'm glad you took my recommendation!👍
They look cooler and they're fun to make.
Damn trolls need to go back under their bridges. I’m here cause I love what you do with your channel and I know it takes lots of work. Great video Paul, thank you for all you do my friend.
Hey...clippetty clop....remember the troll got his butt kicked off the bridge
Great project, looking forward for the development of this. I am sure you can show a lot more about the boost converters. Thank you, Paul.
This man deserves a medal . Love the way this man explains the topic whic are deemed tough to understand without a proper intuition.
As already said, ignore the trolls! I love your videos BECAUSE they're unscripted and you show the mistakes and talk through how to fix them. I've learned so much! Keep up the great work.
I've been able to follow a few of your videos. I really like and enjoy the simplicity of these projects. With a deeper understanding of what's actually taking place. I was wondering about what defines the anode or cathode, when you said polarized, it made everything make sense. I love your content, please keep it coming.
learnelectronics posts a new video:
My wife: Ah shit here we go again...
Me: dumping boxes of electronics out on the floor and heating up the soldering iron.
Great learning series for us novices. BTW, glad you don't use a script, I enjoy listening to your thoughts!
The drawing comes to life. It's always good to see proof that your design works. Thanks for the video!
Great video Paul! Don't worry about negative comments like the script. I know you speak from the heart and your love of passing on knowledge and I for one appreciate it and you more than I am able to convey. Take care and Merry Christmas
Thanks for all the videos. I am from denmark and love it.
this is really good stuff mate thanks for sharing
Keep up the good work, I'm learning and enjoying it
Keep it unscripted brother...love this series, looking fwd to the pwm controller addition into the circuit.
I hope this counts as studying for my power electronics final on Friday :)
Keep up the great videos Paul!
Don’t let Trolls stop you making videos or going on. I learn so much from you it’s insane. So many mistakes I didn’t make from watching your vids. Thank you Electronic God
Wow...I just now looked at your Amazon store to see if I could find that cool tester....you have so much great stuff collected there. I will shop there first from now on.
Thank you. Great video. 100%.
Definite thumb up! Practical persons like you are most appreciated by practical folks like all of us. I watch it once, gather my components, and followed you in real time the next time I watched it again, and build it as you do it. That's perfect, sir. You're a great coach. Oh and don't worry about arm-chair critics, they're a dime-a-dozen. You are solid gold to us. Looking for more from you, cheers!
Glad it was helpful!
I love tinkering with buck/boost/sepic. I'd love to build a Sepic that's dependable, stable, acurite and powerful.
Great video - Thank you for posting!
Glad you enjoyed it!
Thank you. This has cleared things up for me. I was wondering if a boost converter could be built using just a micro controller, capacitors and diodes. Now I know that boost converters need an inductor. I want to experiment with bootstrap circuits for N channel mosfets.
Nice, simple circuit.
Don’t change anything you do homeboy. You’re a true G!
Hey Paul, always love your videos - never once did you sound scripted to me....don't know why anyone would think so.
I don't know what Mr. Check your script was bitching about, forget him. Circuit looking good so far. What about a lesson on winding a coil on a torrid? Have a good day. Thanks, Paul.
I do not know what happend here regards to the negative comments, but that day i see a script, i`m out. Do not change anything man! Good work! :)
Man what script are they talking about, this aint an entertainment show, keep the good work pal👏🏻👍🏻
Thanks for taking the time to produce these videos! It helps noobs like me to learn. 👍🏻
Glad to help!
Can't wait to see your part two on this.
That was part 2, part 3 will be up in after Christmas.
@@learnelectronics oops, fair enough on the "parts", but yeah, can't wait!
As always, a great video.
You have always done a great job, I don't know why so. Eone would have. Anything negative to say about your speech. I can see someone not being able. To follow. Along because of.veiwing angles or learning differences but that's why we have. Comment sections so others can fill in the parts that are to difficult to teach in one episode. People hear. Have always helped me in the Comments and it's made me a much better for it. This is a great community and I thank you all and especially all the work and time you spent building it
Helpful video 👍
as long as im subscribed to Paul's channel iv never seen him use a script. "WHAT YA SE/HEAR IS WHAT YA GET!!" no bull-sh*t, no crappy info, and definitely no bad continent. He's Just a Guy Who Make's Awesome Video's. : ) & hope i hope he makes many more!!!
P.S. iv created a folder in my favorites called Paul's boost converter videos. & i'm saving these one's into it because i'm going to make it( but maybe only up to 30/40 volts. instead of the 100 plus ) so i looking forward to the rest of the vid's in this project!! : )
OH and i finally got my self an anti-static work top Matt. I'v always forgot to buy one when even buying parts ETC. but had my eye on the same one you use for ages & it came dis-morning, i'm well happy with it.
AND I FIXED THE VOLUME PROBLEM I HAD WITH MY LAPTOP FROM SPILLING CHAMPAGNE ON IT THE NIGHT YOU REACHED THE 100K SUB's BLIND ME DID SEE THAT THERE WAS SEPARATE VOLUME BUTTONS OFF TO THE SIDE OF THE KEYBOARD THAT WERE STUCK WITH CRAP & DIRT FROM THE LIQUID SPILLING ON IT. (I MEAN IT's KINDA YOUR FAULT PAUL FOR HAVING SUCH AN AWESOME CHANNEL & GETTING TO THE !00K {JUST KIDDING} )) SO HAPPY ITS FIXED NOW COZ I CAN WATCH FULL SCREEN NOW AGAIN. YOU WOULD BELIEVE WHAT I HAD TO SET UP JUST TO KEEP THE SOUND ON WHEN WATCHING STUFF!! : ). anyway cant wait for the boost converter video!! : )
Don’t get a script! You have one the clearest electronics channels, certainly for a newbie like me, if you can do that freehand, in your easy and likeable way then good on you. (Just say “close enough for government work more - love it)
Hi Paul, don't change anything, you got 101k subscribers by being who you are, the number of subscribers will just go up..thank you for sharing :)
Thanks v much.. Good game. ✌️🇧🇭
Messed with this once so far, believe that the input voltage were about 15Vdc and an 555 pwm at about 70kHz, something in my mind told me that I should check the output voltage because of the capacitor.... 35V running at 70Vdc. It didn't blow up at least. 🤣
But I guess the inductor were too small because it had almost no output current.
Hey Paul, ignore the crappy comments, those of us who are genuinely interested in your channel appreciate the knowledge and information that you pass on to us for free. Keep up the excellent work, stay safe. have a merry Christmas and a happy new year everyone 😎👍
I appreciate that!
Nice video bro
Thank you for the video... Please how can I program arduino uno pwm to control the mosfet switch
Great session again. I have inductors that look like a resistor can I confirm that you mentioned using them but preferred to make your own for this project? Thx
Also Paul, at 7:14 of the video you showed the PWM/Frequency generator you reviewed about a year ago. Looks like it's hooked up in a case. Did you do a video of how you mounted in the case and the connections? I would really be interested in mounting my similar generator like yours.
I was wondering if you could do a video explaining who the heck henry is and why hes micro for us dummies on this side of the screen. Love what you are doing man! Keep up the good work!
No script please. I enjoy you thinking aloud. It’s what we all do when we are prototyping and experimenting
Do you think we can get a parts List when the project is done. I think I would like to build this.
Merci!
tripling or quadrupling voltage is the easy no problem part should expect to do that easy, having enough amps for it to be use for anything is the hard part. I would exspect you to hit the voltage goal from the get-go unless your testing parts you don't plan to use.
I also think that inductors useless. but maybe I should watch first idk I'm 4min in/.
Great! No Smoke... Lol
As far as you explaining things you are doing great!
Sad to say the world is full of ......... :-)
How did that go? Oh I got it, "It's Alive!" LOL
Thanks for the video and all you do...
LLAP
Is there any way to make it more stable with passive components?
Can we increase the size of the inductor, to get better efficiency?
Script?! We don't need no stinking script. Ad lib, the way to go.
Thanks Paul.
i use 25v capacitor is tripple the input voltage 1.25v to 3v is good perhaps higher voltage capacitor boost voltage bit more hopefully is mystical electro components, in future perhaps can charge are devices with super fast charging and power effiencently
Cool are you going to put it on PCBway when done? Oh I got a 20 dollar amazon gift card for Xmas today so I ordered the Velleman Soldering station from your store. Really excited to have an actual soldering station. Can't beat the price of 18 bucks.
2:28 That's a serious problem buddy xD
would an NE555 work for basic pwm control with additional potentiometer ?
Absolutely
Would a NE555 timer as PWM generator, with V.out as a reference to modulate the PWM duty cycle (as a regulating feedback), be a "good" low-cost MOSFET driver?
Yes, as long as you don't need like single hertz precision.
I'll have to think and tinker about it, to find out which pin to provide with the V.out (or some bridge-divided multiple thereof to not harm the 555), and have another look at the 555's datasheet.
In PWM circuits, pins 2 and 6 (trigger and threshold) are connected to the same node (in the middle of the RC oscillator); maybe one of these two would be of 1ny help? Or maybe on pin 5 (control)?
Pin 5 will modulate the frequency
Hi paul,did you finish this project,I build tube amps,wind my own TXs(power),interesting to see(hear ) the results.
Trolls live under bridges.
Not yet
Will you make a episode on how to turn dc to ac
PAUL, THAT TESTER YOU USED FOR CHECKING THE INDUCTOR YOU USED, DID YOU DO A TEAR DOWN OF IT IN ANOTHER VIDEO! IF NOT COULD YOU TELL ME WHICH CPU IT USE'S PLEASE ?? BECAUSE, I JUST GOT A KIT BUILD TRANSISTOR TESTER IN THE MAIL DIS-MORNING (ALONG WITH AN ANTI-STATIC MATT WHICH I HAD MY EYE ON FOR AGES BUT KEPT FORGETTING TO BUY. IT'S THE VERY SAME ONE YOU HAVE & IM WELL HAPPY WITH IT) & ALSO A KIT BUILD FUNCTION GEN. BUT THE TRANSISTOR TESTER ITS THE "GM328" I WAS JUST WONDERING IF THAT WAS THE SAME COZ I HEARD MY ONE IS VERY GOOD FOR THE MONEY & COMMON TO.. DO YOU KNOW OF IT?? ITS GOT PWM & A SQUARE WAVE GEN ON IT & IT USES THE AT-MEGA328P DIP28 WITH IC seat. (WHAT EVER THAT MEANS? "IC SEAT") BUT WAS JUST WONDERING IF YOU KNOW IF THE TESTER HAS THE SAME CHIP. OR IF YOU'VE HEARD OF OF THE TESTER I GOT AND IF ITS GOOD IN YOU OPINION. BECAUSE I REALLY VALUE YOUR OPINION MORE THAN LOT OF OTHERS... SORRY FOR THE BIG LONG COMMENTS.
P.S. THE TESTER WAS LESS THAN 20 BUCKS TOO. SOOO!!! NO TEARS WILL BE LOST IF ITS CRAP!! ; )
nice work Mr. Paul but can we know how long did the circuit spend running on the test?
You saw it
'UC3842AN' lets see how this ic can produce the PWM signals, can't wait please be soon.... Sir! 🤪👍
check the temperature of your mosfet, I once designed a similar circuit but the mosfet would heat up so much that it felt dangerous
MOSFET can handle quite high temps, so high that they de-solder themselves 200 degrees Celsius and higher are no problem for some.
Not that they should operate at those temperatures, but some does.
So yes, you has valid point.
What about load testing...??
What happens if we use ne555 here
is it safe to use high voltage on breadboard?
no
I reckon you otta get a director and producer.
How much power could that resistor handle? 😳
5W
Dude, just keep it the real you :-}
Why are trolls such miserable souls? Frigg 'em Paul.... frig 'em all! Looking forward to the conclusion of this booster circuit.
Next part video bro
Who's Miss Peek? 😁
"so far and so good"
Is this a joule thief?
DON'T FEED THE TROLLS!!!
Script? I don't need no stinking script !!! Probably the same flake that whined about the give-away....Nice job Paul, keep them coming ...
I'm a noob... what are you boosting?
Voltage
@@learnelectronics what can I use this booster for? Wondering if it could be applied to radio controlled electronics.
Please adjust camera
I can't believe this clown has no script.
Next thing you know he'll be blaming his crew for the lame cinematography.
😉
IMHO it's really the lighting crew he needs to replace. 😁
So anyone getting their giveaway . 😭😭 I didn't win
well scripted thanks again
i didnt make the scripted comment
the mistakes is were you learn something
