Look what happens to a 230 Volt PCB in salt water #experiment
Interesting experiment on what happens to a PCB powered by 230 Volt AC when it is immerged in water. In a second moment, a lot of salt is added to the water which increases its conductivity.
⚠️ DON'T TRY THIS AT HOME ⚠️
Curiosity: I live in Italy, the theoretical voltage of the electricity line is 230 Volts, sometimes (for technical reasons) energy suppliers increase the voltage up to a maximum of 250 Volts. While I was recording this video the voltage was 250 Volts as read by the yellow multimeter.
Chapters:
00:00 - Intro
00:05 - Water
00:32 - Bubbles
00:48 - Salt
00:51 - Spark
01:14 - Fear
01:40 - Break Power
01:48 - Hot Water
01:58 - Circuit after bath
02:12 - END
⚠️WARNING: This video is only for demonstration. I don't take any responsibility.
⚠️WARNING: In this video a very dangerous experiment is performed, do not imitate it.

Hight Voltage and Electrostatic Polarity Detector circuit
Переглядів 2,4 тис.10 місяців тому
This circuit is an Electrostatic Polarity Detector, it is able to detects electrostatic charges and indicates their polarity with two LEDs (Red LED = Positive charge, BLUE LED = Negative charge). The core of this circuit is a CD4011, a Gate NAND IC. For this project I decided to make the circuit on a prototyping board, and as box I used a glass jar, which gives it a particular look with a vinta...

Nice cat and video! 👍
Thank you😊
Can I use it for rpm on motorcycle?
Yes, but with this diagram and LM3914 prefer: ua-cam.com/video/Kowv-nJnX7o/v-deo.htmlsi=jgt_C9HD94784AmU
@@Stefano91ste thanks ❤️
wher is schematic diagram plees
In the end of the video
@@Stefano91ste than you
great job sir. Its working perfectly, i added a transistor to switch an LED with higher voltage rating and also to slow down the flashing speed i connected two 1uf in parallel .
Sounds cool😎
The way this guy does not say a word I don't think he's going to get 100,000 subscribers
And what does it mean?
Buongiorno. Si potrebbe cambiare il display led??il mio non si vede piu
Buonasera, nel mio caso non era possibile cambiarlo perché tutto sigillato in una resina trasparente
@@Stefano91ste peccato…anche nel mio..
il mio 680 g non funziona piu in portat ohm . mentre in volt funziona bene . potete darmi una mano ?
Ciao, hai provato a smontare lo strumento per vedere se ci sono componenti o piste danneggiati?
@@Stefano91ste smontato e pulito tutti i connettori e ho risolto. E tornato a funzionare. Grazie
thank you sir, could not have done it without this video!
So when I finished and plugged it in, it started blinking and making a sound like the thumper from dune, any ideas before I take it all apart? lol
My laser light is also 303 i try all method even the focal lentgh etc but i cant burn a matchstick did i have to change my battery i have the battery which come with the laser can i change it with lithium battery does it have changes on my laser power please reply ❤
Hi, unfortunately after 2016 the lasers were weakened for safety reasons. With those that can be purchased nowadays it is impossible to carry out these experiments that could have been carried out years ago
cosa ho appena visto?
Ciao, è una versione industriale del salvavita di casa per dirla in breve.
Why does mine not working
Hi, so without seeing your kit I couldn't answer, try to double check all the welds and that the components have been assembled in the right way
5000mW? Complete nonsense! This laser has 1mW, not more!
Hi, unfortunately after 2016 the lasers were weakened for safety reasons. With those lasers can be purchased nowadays it is impossible to carry out these experiments that could have been carried out years ago.
Only my blue LED is working. And the coil is not lighting any bulbs.😢
Hi, sorry for my late reply, were you able to resolve it? If not, try rechecking the soldering, especially that of the small copper wire of the coil.
Please explain how to get the power supply .
Hi, this coil need 15-24 volt dc with 2A
do you just create these projects out of your own mind? or were these some kind of assignment? nice job!
No assignment, just years of passion for electronics. Thanks for the comment😊
@@Stefano91ste that's what I like to hear!
@@Stefano91ste was this self taught? Or did you have to go to university? You're very good!
The mic didn't have any connections . Should I do soldering? Pleasee help sir!
Ciao Andrea ho una Ford fiesta titanium del 2010 ,ho scoperto di non avere acqua ,quando sono andato a metterla bolliva è usciva di fuori insieme al fumo ,la ventola non attaccava ,secondo te ho rotto la testata?
Ciao, se dovessi rompere la guarnizione della testata vedresti del fumo chiaro/ bianco uscire dallo scarico. Ad ogni modo vai immediatamente da un meccanico. Ps: non so chi sia Andrea
😊😊😊😊😊
App link
Hi, I haven't used that app for several years, I found it on the google play store, try doing a search with the term "EMF Meter" on your app store
Whats that your using to heat it on? Whats it called
Hi, I added a small 12v fan on the heatsink if that's what you mean
What software did you use for your occiloscope ?
Thanks a lot, it works very well!
can i also use a 680k resistor
I love it!
How operate on Dot mode?
Please reply, What is the Uf and volts of these capacitors ??? Please reply 🙏🙏❤
This is pure waste of time.
diy ultrasonic cleaner 😂
Magic soup
what this👎
A fun ecperiment
most of the board looks fine... is the HV components of the board damaged? also still kind of surprised the breaker took that long to trip due to a short.
Yes, the low voltage part was deactivated immediately, while the high voltage remained active. I have two emergency switches, the first is dedicated to the laboratory, the second covers the whole house (including the laboratory) I assume they didn't stop immediately since dispersion was minimal and confined to the plastic container
I love itttttttt!!!
Thanks 🙏
What happen?😂
Watch the video😊
Hola muchas gracias por el aporte, una consulta porque pones en la lista "1x 3 MΩ Resistor 1/4 Watt" pero finalmente veo en el circuito que usas de 4.7 MΩ ??? o es mejor la de 4.7M ??
Good morning, how would i be able to adapt this for 24v? Many thanks
can we use a thermistor please reply me
I got a a few batteries from Jcar and took my vape on with me to make sure I got the right ones and they say FIRE HAZARD NOT FOR VAPE. So,does that mean I can't use them or what they sold it to me and said I could use them
What have you been doing, my friend?
Hi :) The same old stuff, I've moved away a bit from posting on social media
Very useful to me -- i received my package from Ebay with NO DESCRIPTIONs at all: no info on the modules, no paper, not even an internet link. Thank you!
Thank you for appreciating my work
I use that laser and the battery is 6800 mah the full charge is 4.2 v and its a 18650
Is the dielectric layer toxic if the masking comes off?
Hi, I am not informed about this, hope JLCPCB can answer you
I just built this one and the numbers are not staying on unless I press the toggles any idea why that’s happening?
Hi, I would try to double-check the soldering
Normal operation. Mine does it too. The circuit that drives the display has radio interference. It goes dark so you can hear the fm signal. Has static when it's on.
ma l'esp32 riesce anche a emulare giochi del gba o solo del gb e gbc?
Ciao, quello del mio video arriva al game boy color.. io però poi non ho più segito il progetto
@@Stefano91ste ah io stavo pensando a provare a crearne uno sostituendo il chip da 4 megabyte su esp32 a 16 megabyte però non sapevo cosa aspettarmi da un microcontrollore...
How to purchase this vu pc board complete kit
where do you connect the microphone on the breadboard
👍👍👍💪💪💪❤️
Will it still work if it is flat positive? Pls respond❤
Hi, I've never tried it but I think it works
Thx bro I'm buying it tomorrow If u want u should do a video about it cuz a lot of people are asking the same question 😀
Does it detect metals like a sensor, or give me a diagram of a device that detects metal with an ion sensor?
Ciao Stefano, grazie al tuo video sono riuscito a far funzionare il kit e ho gia fatto i primi esperimenti. Purtroppo l'audio non funziona. La continuità dal connettore jack al circuito integrato e al condensatore c'è. La scintilla c'è. Purtroppo non si sente nulla. Qualche idea? Grazie?
