I love the way you say "dangerous" keep up the good work! Very dangerous lamp indeed!

Cat opening the video is great...😂

4:59 his fire extinguisher 🧯 LMFAO I love when he say that about his BEEEEEEEER! 🤣🤣🤣

I dont care about your accent ,as long i can understand. Good aducation keep it up...

I just made one! I added a PTC and a MOV to the circuit and its is 36 LEDs hardwired to 120V mains and will run 24x7. Used a 0.1 uF 400V cap, 1500 Ohm resistor (in place of the 2x100 Ohm in parallel) to give me 9 mA through the resistors. Nothing even gets warm. Measured total consumption at 1.2W !! will throw away the 2.4W light it replaced. Thanks Danny for the wonderful idea.

Diode, I love your work. On these tear downs like this one that reveal circuit deficiencies like the undersized smoothing capacitor. It would be enjoyable to see you make modifications to the circuit to correct it or go into greater detail on how to redesign a circuit that would not be susceptible to reversed polarity like in this case.

Again a great vid from DiodeGoneWild

Perfektné video ako aj ostatné, len škoda že na KZfaq nie je viac takých videí po slovensky/česky.

Výborné video. Přišla mi angličtina "velice česká", přirozená. Nu a vysvětlení záhady po pár minutách - lahvoň Žatec vše vysvětluje. Pěkné.

4:11 Wow i never thought that! Thanks!

Your videos are realy helpful for me...nice video

I just love the way u speak.. And do keep the good analysis..

Nice fire extinguisher! I have a similar one here too. ; ) Thoroughly enjoy your channel. Take care.

Your cat is so cute!😍

Love your fire extinguisher !!

caps dropper is better than switching one i think, it can be deem even over half it rated voltage, high efficiency(heat dissipated is mostly on the led only), easy and cheaper to repair(except overvoltage).

Yes yes pls make videos on your new LEDs I am eagerly waiting this one was very interesting 😎

thank you. You have potentially save my life !

Veritáska (cat ) makes the video much better!

I really like your chanel! 😃👍

How did you mod that cheap meter to be watt meter? Please make a tutorial video or something on your website.

one time i was electrecutet by my doorbel because it wasn't working. it was from soviet era.

Zrób film na temat tego Twojego watomierza który zrobiłeś z taniego multimetru.😊😊 Po prostu mam problem ze znalezieniem tego tematu w twojej play liście. Oglądam Twoje filmy od około pół roku i jestem pod naprawdę pozytywnym wrażeniem. Zawsze jest łapka w górę. Mam nadzieję że kiedyś skosztuję tego Twojego piwa. 😊😊👍👍

Do you disprove or approve the neon mains test screwdrivers. Ive seen you use them before and as you look at all this dogey unsafe Chinese stuff I assume you like the neons?

Yea bought a cob led spot light from ebay recently, stated 15 watts, actual.. 4 watts lol, but at least it doesn't flicker, the corn cob types do even if they claim they don't, i haven't tried the more expensive ones. 72 led 6736 SMD at 7 watts, actual... 2...

Máte výrazný český prízvuk, ale napriek tomu mám veľmi rád Váš kanál.

Good video

I have that problem with meters all the time. the older meters dont have a shut down timer perhaps you could design a simple power off timer for meters?

Nice and useful Video Now I know that the discovered leds are dangerous: I bought many Chinese LED lamps but fortunately they are all covered at least by a transparent layer ... maybe they last less than expected, I have already changed 3 !!! A single led has burnt and the whole lamp goes out. but I take it off and replace the PCB with the broken LED (corn lamps: the second from left in your video at 10:10) and by two broken I 'll take out a good one.(04:45) In the video where you presented the Clamp it I noticed that this kind of clamp unlike other more expensive and precise, is very sensitive to the position of the thread under examination, do some testing and you'll see the difference, it may be that I'm wrong but I think I saw well in the other video, if you think that also the high precision clamps of which I spoke to you (I use one at work: i'm check the electric light meters) specify to keep the wire as more perpendicular and centered as possible of the torus (05:30) lidl knife? :-)) have a nice night

I've had a shock from one of those in the past.

Hi, my ATX SMPS stopped working. I checked & replaced 3 capacitors with correct polarity & 1 ceramic capacitor of 2kv instead of original 1kv. Now smps turns on but gives little humming noise. Voltages are ok on all pins & if small load is connected it works. But it is not accepting any load on 12v rail. On 5v it's accepting, but humming is increasing. I checked all capacitors/transistors/mosfets/octo cpouler with multimeter. What could be the problem??

I have a transformerless LED driver from a China LED Bulb but it's voltage output is more than 300V DC. Can I reduce the V-out to 45V DC using Voltage Divider Method? Will it be safe to used to turn on several SMD LED in series??

at @4:29 how does the meter show power because the dial is set to show the voltage?

Hello DiodeGoneWild, where you are buy the multimeter??

What was the price of the meter? I can see that Voltcraft makes rebranding and the original construction is Uni-T UT 210E which costs around 35-40$.

I really like your new meter pls make video as soon as possible I am waiting😀

Thanks!

Plase can you make video on how a pure sine wave inverter works?

My guess on this design: In China (and the US and the UK) they use "polarized plugs". You can't turn them around like here in europe, so the described problem of reversed L/N does not occur. Maybe some greedy sellers simply screw an EU plug (or lamp socket) on their devices and sell them on eBay?

Can we get the brand and model number for that clamp meter?

Somehow im not supprised that there is no switchmode inside, capacitive reactance seems to be too common. The cob one will be similar, but at least it has a plastic cover. Ahh the little yellow meter has the better pcb in, shame the icl7106 is a cob :-(. I have quite a few of the yellow meters, the earlier 830b ones are not so bad. I don't use them for high voltage. You are back home? The cat..

About multimeter: on ebay there are cheaper same models. Did you choose your's on some special tech. data or just acc. to look and price?

5:03 I see Žatec beer, are you from Czech republic :D ?

The maybe its exposed because most spotlight sockets also have a glass cover in front BUT there are many that havent

Are you sure that battery in multimeter is flat? Almost all multimeters have some safety mechanism for turning off if it's powered on few minutes without change. So you should move the range pointer.

How test pawer puissance with multimeter thanks

Wonderful

hey mate, there is 230V in almost whole europe (not only EU) for like 10+ years !

Where are You working? Whats Your profession?

Omg I had the same led in India and its capacitor blew(the electrolytic one) and I changed it with another one and now it works...

Some chinese manufacturers just wanna reduce cost. Sometimes they draw a very thin serpentine line on the board to act as a fuse. I had dealed with some cheapest Chinese lamps and many of them save cost in some unimaginable way. larger cheapest boards even have hundreds of leds directly to the rectified 300v DC.

The warning disclaimer was horrifying 😂😂

Seriously...my words can change like him after watching his videos.....😂😂

I think, need correct this scheme for better working. Remove one 100 Ohm resistor, change capacitor 4.7mkF to 10mkF, 560nF to 1mkF

Ale povedzme si pravdu, aká je pravdepodobnosť, že sa toho človek reálne dotkne? Bude to mať hore v lampe, kde je mimochodom fáza pevne daná a nehrozí výmena s N čiže dostal by už "len" 70V. Problém by síce ešte mohol byť u stolnej lampy, keďže tam toto neplatí. Ale je otázne či by si prstom reálne spravil kontakt na tie vodivé plochy okolo LEDiek. Nehovorím že je to úplne v poriadku, ale boli tu už aj nebezpečnejšie veci.

Hello/(Ahoj) , Why the inrush current is going to destroy the LEDs ? I know that inrush can destroy bridge rectifier because of discharged capacitor

How are you measuring AC power with that Multimeter. Please make a tutorial of that too.

Hey Nikola Tesla your cat is nice!

Just bought this, do you recommend throwing it out? Even though I like dodgy electronics like you

If you buy any electronic item, always look for the UL or ETL mark (if you're in US/Canada). In Europe, look for equivalent safety marks. Some Chinese manufacturers will put fake safety certification marks on their products, so it's best to go to the website and verify the product is actually listed. Most reputable retailers will not sell products without safety certifications, but eBay and AliExpress and Bangood will sell any old shit.

I have this over 3 led lamp. Now i change all to Philips LED

5v 8w Usb Soldering iron Teardown and review please

Hej danyk vydával by si videá aj v češtine ??

The red inlet @3:44 is direct not through switch?

Use a Ni-MH in the meter, no more wasted batteries.

Tell me how to save from 220 ac Isolation?

Looks like Kaufland Batteries.

What is the cats Name?

Your cat is so beautiful 😃

The cat😂 love your videos

Říkal jsem si, jakej ind to natáčí takovou hrubou angličtinou (ne že bych měl lepší, viz kzfaq.info/get/bejne/qeBgo6ilsL-yfIE.html), ale pak jsem narazil na lahev Žateckéh piva (5:03) a už chápu. Skvělá práce :)

I have e27 LED Like this i got it from WISH.(220-240V 4W COOLWHITE 48LEDs e27)

Hi, would like to contact you somehow? Sent you an email on your homepage - but seems you dont check it? I have some suggestions... thanks!

Great video - that is the worst LED bulb I have seen.

The cat is so cute

Like for the cat ! ))

Quality will be excellent if you buy at a little high price.

Please test the cat also if it is good quality

Ten přízvuk je mega, ale kanál je naučný a zábavný.

Możesz odpisać po czesku. Mieszkałem blisko czeskiej granicy. 200m. Teraz w Danii.

WHO had been electrocuted by Atx power supplies?

Your cat is very cute

What will happen if i just like mains true me ? i have try done it burn the fuses couple times its nice u become live :D :D :D :D

A new video!

You cat now can understanding some circuits

In my country we don't have "Ground". Only live and neutral.

You are from Germany or the czech republic? Cool. The package of the 9v says "Kaufland Classics" and Kaufland is a German Company so you are living near the border.

what kind of a fire extinguisher is it ? 😂

your cat is so cute

It's not the volts that kill...oh wait, maybe it is 😉

Cute cat 😘

I like his accent.

i vote capacitive dropper circuit

The clamp meter looks just lie the UNI-T 210E meter.

I like all the warnings because every time i am playing with voltage i think out that and it then shocks me and i am like F***ck(except i dont swera that much)

Make sure you don't electrocute the cat..!! :)
