HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face.
It will kill me one day. I'm doing ok right now, but someday...

Describing this as a "classic" is a bit of an understatement, as this circuit is a stage in the Cockcroft-Walton generator! It's important in the history of particle physics.
Awesome plz make more for classic circuits.
I remember Pennsylvania when I was a truck driver in 1991. I used to think that Illinois had the worst roads in the country until I drove through Pennsylvania!
Maybe it's just the interstate I was on? I remember the roads to this day!
Cool circuit and great solo at the end-cheers!
Good morning Paul, thank you very much for showing and playing the guitar! and thank you very much for the voltage doubler. Best wishes from Germany, Joachim
Very nice bro! Yeah i love these classic circuits. Please do more of them you teach and show things very well))
I also lovethe basic circuits, so much to learn. They are fantastic at teaching, even better than basic courses.
Very nice guitar playing at the end. And the circuit was cool too.
Very cool circuit. Thanks for the jam.
Thank you for your effort to educate us. It is much appreciated. I think I needed more explanation of what is going on with the electricity, itself. How the caps are being charged and how that charge is added to the voltage that is coming from the supply (mains.) Please make a follow-up video, so I can truly learn what is happening. Please and thank you.
Cool yet simple circuit. Thanks Paul.
Got an email today, my (meaning your) Pico breakout boards have been shipped. Thank you for making them sharable so I don't need to replicate the time making my own. I might make my own add on board with a perf board to make some additional plug in modules and such apart from a single I2C
Glad there was no mushroom cloud above that circuit. I had seen the voltage doubler long ago, however I could not visualize how it worked. This time, when you explained the design, it made sense. Nice musical ending, my pleasure to help out a bit.
I see its been said below but again this classic circuits series is great keep em coming Paul
Good teacher and nice music.
I'm scared of that circuit. 😁 good guitar pickin there too. Thanks for the video!
Great rethim...... + lovly job... Thanks v much Sir ✌️
Nice to see Penn state. I grew up 2 miles from the village of Penn in Buckinghamshire in the UK where the Penn family originated. One member of which founded the state. Small world.
Your gettin better at the guitar my friend .
I was really looking forward to that volage doubler but the voltage doubler will have to do( clearly I'm just ribbin' ya bud ;) ) xD Very useful circuit indeed! Nice riffs too!
Thank you so much
cool guitar at the end1 wonder why it had ten volts input and o out put is that normal?
Love the Rural King shirt.
Very Cool..
Thanks.So, the Increase in Voltage is not linear to the Input Voltage ?
Ah the mystical volage. Love it.
Thanks.
💯 A volagé doubler sounds way cooler 😎
All the voles agree.
On these voltage doubler circuits what kind of amps are you getting?
THAT's what I wonder about. It seems it depends on the supply. I'm still trying to get a grip on current :-)
Esp safely measuring. I've fried a lotta shit in the process :-)
I love the fact that you caught the illegal U-turn. lol
Your driving on route 22 /30 looks very familiar to me. I was just on that road yesterday. As I live in Robinson Township.
Cool. I was on my way to Guitar Center.
Nice Tele!
Thanks
Looks a lot like the 1st stage of the voltage multiplier in a negative ion generator !
So if I was to get "large components" I could actually use all 100 amps from the main? I am just curious how many dc amps could be achieved. Supper capacitor voltage dobbler ark cannon? Let me know. Long time sub. Really enjoy your work. Your videos are always entertaining and really informative. I always have something to take away and the end of them. Thanks
I have a doubt.
While connecting the negative terminal of a dc source to the positive end of an electrolytic capacitor is dangerous (may lead to explosion), then how is it possible to connect the electrolytic capacitor to an ac supply ?
So your just partial rectifying the circuit ?
I didn't know you were in PA. I was born in Uniontown (about 50 miles south of Pittsburgh) and grew up in Point Marion. 👍
I'm in Ohio. Right on the border.
@@learnelectronics Oh ok 👍 I live in West Virginia now (Fairmont). Grew up in PA, about 32 years and been in WV about 5 years now.
I'm right on the border of where Ohio, Wv, and Pa come together. About 300yrds from the Ohio River. I worked most of my life in Pittsburgh. Where I am in Ohio is economically dead.
Hey Yinzer, after you checked the AC coming from the variac and verified it was 10 volts AC (7:28 min), perhaps a check of the AC between the anode side of cap 1 and ground would have been instructive. Also, why did the meter show 13.36 DC volts (5:49 min.) at the output before you turned on the variac?
I have a ZOOM 1010 effects peddle. its been in the press since i was 17 or 18. just found it again recently got a 12 volt power supply it didn't work. then opened it up nothing obvious wrong by eye but, i found out its 9 volts centre negative. 300mA. needed to work it. i haven't jimmyed up a connector to checked it yet to see if it works but Anyway what im getting at is "DO YOU WANT IT". let me know where to send it and i'll post it off. a kinda thank you for all iv learned off ya! i hope its working or at least an easy fix. ANYWAY LET ME KNOW!!
One possible reason for the DC voltage drop is the AC fluctuations in the charging loop.
can you REDUCE voltage in the same way? with a similar curcuit... i guess it would be a cascade divider ?
to reduce a high voltage from an alternating HV into low voltage DC but higher current..
if i just use a resistor divider there are losses in the other resistor... no ?
somehow i see caps being charged in series then discharging on parallel... to bring the voltage down... yes?
Don't know why those elctrolytic capacitors didn't blow when the voltage reversed on them?
You should have discharged (shorted) the capacitor once after first boosting the input voltage. That is the reason why you couldnt get decent voltage levels after first attemt.
Did your variac come with those banana jacks?
Great circuit, lovely guitar work, but i didn't recognise the tune.
It was improvised on the spot.
Theme song have capacitor will travel ! 😁👍🤖
I love Tele's 🙂
Me too. I have 2 teles, an Ultra Strat, and a Les Paul. That 52 reissue i played in the video gets used more than any other.
@@learnelectronics nice 🙂 I have a 60th anniversary '52 Hotrod. She's my favourite
Your meter was the only 'load' on the circuit, accounting for readings not being what was expected till it could settle.
Why did you use an electrolytic cap as opposed to a non-polarized part on the input leg? I suspect your circuit died in concert with that cap as its polarity was reversed (although I've never tried this so I'm not sure). Try again with a non-polarized part and see what happens?
Juat for fun, I'm gonna be not picky. Your white board says VOLAGE not voltage. :) Don't hit me. I found it funny.
Your spelling of Just did the same thing for me, the irony 😅
Nice video but maybe consider remaking it.
You have written Volage Doubler “Cascade”, easy mistake but you continue.
Anode of a capacitor, ok positive side, but it’s not an anode.
Connection, cathode of diode 1, ok, but cathode of diode 2, should be anode.
You could refer to the ac input as line & neutral or live and neutral, and you state its connected to the cathodes to one of the 2 electrolytic resistors!
The demonstration that doesn’t work is not helpful either. Sorry!
This may sound a bit picky because most of us know what you mean but for those new to electronics, which I assume this is aimed at, you could cause a bit of confusion.
Otherwise I like your videos. Thanks.
Voltage doubler-an easy peasy circuit you should know. Let me teach you how to build, but if you're not a certified expert like me, don't do it. 🔧🚿🧻🔨 Done, let's measure what we've got here.
EDIT:
A 40% Voltage increaser. An easy peasy circuit you should know. Let me teach you...
You realize you are doubling the peak value of 10v rms which is 14.14v. Times 2 males it 28.28VDC. What you had on your DVM. I does not double or triple.
Warning: may cause acute Darwinism.
Don’t show this too electroboom lmfao.
He's covered it: this is a stage of the Cockcroft-Walton generator. This was used to create high voltages for early particle accelerators.
I'm confused I thought you lived in Ohio
i think he does. PA is just an hour drive from where he is.
I live in Ohio, on the border, about 30 miles from Pittsburgh.
Cray thing Paul, I noticed your variac power light going on and off in the video..
