Thanks!

Thanks

Hi, unfortunately it quickly disappeared from the market, which was a real shame :(

@Stefano91ste why isn't it marketed in Indonesia?

scratch that I missed the timestamp link....:( got it!

Hi, the wiring diagram is inserted in the video, towards the end. Alternatively I can suggest you this second version, kzbin.info/www/bejne/ap-2aaurn62Niposi=LmnHddhgl05fo_13 it is the same wiring diagram but updated. Also read the video description for more details😉

@@Stefano91ste thank you so much!

😎⚡️⚡️⚡️

As soon as I find a suitable measuring tool I will do a test

Very wow! 🤩🤩

​@@Stefano91ste I think for that you are gonna need a vacuum capacitor voltage divider and these are really expensive

Hola, no esta a la venta

Hi, I can advise you to connect an active buzzer in parallel to the LED. They are buzzers that have the circuit that makes them sound integrated. Choose one that activates between 2 and 3v.

Hi, not in all cases, or at least in negligible quantities.. mainly it is just electrolysis that separates the oxygen and hydrogen molecules that make up the water. To extract chlorine you need a chlorinator, a slightly more complex machine. A pool chlorinator is a device that uses the process of electrolysis of salt to generate chlorine, which is then used to disinfect the pool water 1. Salt (sodium chloride) is added to the pool water. 2. The water passes through an electrolytic cell, where plates coated in ruthenium or iridium trigger the ionization process. 3. The salt is split into hypochlorous acid and sodium hypochlorite, which are sanitizing agents that kill dirt and bacteria. Finally a control board regulates the amount of chlorine produced and ensures that the water remains clean and safe to swim.

@@Stefano91ste With due respect, not exactly. Oxygen has a standard-potential (E°) of +0.42V (related to hydrogen 0V) and chlorine of +1.396V. This means, salt in aequous solution decomposes by electrolysis just after oxygen into elemental chlorine and sodium hydroxide. A side-reaction into NaOCl is possible, but mostly negligible, as far as no catalist is used.This is the reason, commercial liquid rheostats for AC used to use sodium chloride, but for DC sodium hydroxide was used. Of course with good ventilation due to creation of Brown's gas. Of course, the amount of chlorine depends on voltage, current, concentration and electrode material. However, it is present and can be smelled. Particularly, when non-metallic anodes, like carbon rods are used, that supress formation of chlorides.

Hi, thank you. If the analog instrument you want to connect has + - + inputs, you could connect the common ground and the two positives to the LEDs (the red LED will move the needle up and the blue LED to negative values). If it only has a + - input, the situation is more complicated since a part of the circuit must be designed to generate a negative voltage starting from the positive that goes to the blue LED. I hope I understood your request correctly and explained myself.

@@Stefano91ste Thanks for the rapid reply. Your response was exactly what I needed. I look forward to viewing your videos and learning about building circuits.

Hi, if you respect the circuit diagram and exact components you will see that it will work as in my video

@Stefano91ste I tried many times as it was in the circuit but why I don't know it is not working and also with the same components as you used

Please help me out

Bro which terminal of LED should be connected to transistor ​

That is correct😉

Thank you😎

Thanks, they are made of steel, I made them from an old antenna

Thank you

C'est vrai, salutations😊

Hi, the yellow/orange LED always remains on, while the red one indicates the presence of electromagnetic waves. If the red LED remain on near electrical equipment it is because they emit electromagnetic waves

@ but I didn’t put it near a electrical equipment but the red led is always

Hi, absolutely not, you need a non-polarized capacitor of similar value to the one I used.

Exactly, but without that resistor it is not possible to restore the circuit to its LED off function

Hi, the schematic must be created respecting the data present on the component datasheets, and tested on a breadboard.

Hi, yes! the lights will work as demonstrated in this project

60w + 60w + 100w bulbd

Thanks!

Thanks!

Thanks!

Thank you😁

Thank you, stay tuned😎

Thanks

Thanks

You are right😅

Hi, You could create a circuit that outputs a frequency of 200mHz (1Hz = 1 flash per second) using a NE555 IC.

To make it work in DOT mode it is necessary to remove positive voltage (V+) from pin 9 of the teo LM3915. This is not provided for on this PCB, but I have other videos of vu meters on PCBs with selectable DOT and BAR modes

Hi, It's a strange problem that few other users have encountered, most of the time it was solved by powering the PCB with a battery or a power source that didn't have noise. Others solved it by replacing the 100K resistor with a lower value one. Unfortunately it's difficult to understand what triggers this defect without physically having the users' PCBs available... maybe it also happens because low quality ICs are used, it's a hypothesis.
