I like these videos where you reverse engineer the circuit. Thank you for the explanation!

This device does not only have the "CE" (Chinese Export) label but also the german "GS" sign (means Proof of Security) and "TÜV" sign (Technical Surveillance Organization) which means that it was tested by engineers and should be really safe under all conditions ...

I don't know how I found your channel, probably your doggy charger video, but you are doing gr8 job.

Yay, new video came !

I've seen a lot of products that have both real UV LEDs and also bright blue LEDs to let humans know not to look at it and to let people know that it is on. Of course some of them cheat and don't have any UV at all but most of the ones I've seen have both. And a lot of the fancy new UVC leds are double dye.... and have both in the same package as a safety feature. I've been ordering and experimenting with a lot of uvcc LEDs over the last few years since the technology is becoming more prevalent and maturing. It's really cool and exciting and they just keep getting more and more powerful.

When he mentioned the LEDs flicker at 50Hz, I don’t think it is because one half cycle is going into them as wouldn’t they still flicker at 50Hz if the full AC cycle went into them as they’re directional?

THIS IS MY MAN I LOVE YOU DUDE Xd is that supposed to attract mosquitoes or repel them? If they get repelled then how they get inside ? 😂😂😂😂 Dude I love your videos ...I've been your fan for over a year 😍

1A fuse! That's 230W... (at 230V) 200mA or less would be more appropriate

@anindyamitra5091

6 жыл бұрын

Turborider, 1 A fuse is given for the case when the 430k bleeder resistor or the capacitors shorts out. 200mA fuse would blow up immediately because the initial inrush current is huge due to the capacitors in the circuit.

You could just use a slow reacting fuse. I doubt that the circuit needs more than 200W to charge up the few small caps.

@DiodeGoneWild

That's because of the inrush of the capacitors. Using a slow blow fuse with a lower rating would be better, but I think that slow fuses are more expensive and that's the problem :).

Slow reacting fuses are actually cheaper.

But is it still able to kill the mosquitos after you made it safer?

Why did the mosquito on the package only have 4 legs?

I see LDE1 to LDE4 instead LED1 to LED4, or am I wrong?

I got one in England it actually works and they used audio capacitors lol I bet that capacitor across the LEDs causes the flicker somehow and that resistor producing heat attracts em as well

Its always a pleasure to watch your explanations and schematics :-) Its redicolous how they copy the marketing phrases of products without thinking :-) They seem to copy the chinese marketing policy to europe! OMG! One suggestion for product reviews: what about solar panels and MPP-Tracker for solar panels (max power point)? I think its an interesting technology and i bought a few solar panels recently to test them. Variying from 0.5W up to 50W Peak power. In fact they mostly reach 70% in best sunlight conditions. Some chinese cheap ones only reach 30 - 50% but they are getting cheaper and cheaper. you get 1W/peak for less than 1 Eur nowadays :-)

Thank you

1300 volts is a bit weak for a bug zapper like this. the more powerful ones like the hand held ones has 2300 volts some 2750 volts and I have a large hand held convertible zapper that plugs in which has 3700 volts and bugs explode on contact when they touch the grid. it will give you a hell of a shock.

You just need to learn about the impedance of capacitors in AC circuits. At a fixed frequency (50Hz) the capacitor just acts like a current limiting resistor except that it does not dissipate any power as heat.

Im hungarian, and it means " LED mosquito killer"

i played with this found out UV leds attract moth etc and blue leds mosquitos so i now use 2 UV and 2 BLUE LEDS now it attracts all bugs

DiodeGoneWild One suggestion to make it even more power efficient, for the mode that the UV LEDs are on; Currently the four UV LEDs are in series. What if we place them in 2 parallel branches, 2 LEDs in each branch. The 2 branches should have opposite polarity so that in one half cycle the LEDs of one branch are on and the LEDs of the other branch are off, and the opposite happening in the other half cycle. The Zener and 1N4007 should also be omitted. I guess this way the voltage drop capacitor (2200nF) will help more in decreasing power dissipation (For the mode that the UV LEDs are on).

@zwz.zdenek

2 жыл бұрын

That would take some load off the Zener, but it would also make the efficiency of the capacitive dropper worse, so the only good way is still a full bridge rectifier.

@a000ab

@@zwz.zdenek How does it worsen the efficiency of the capacitive dropper? With my suggestion, for when the NPN transistor (and hence the UV diodes) is off, no current passes through the capacitive dropper at all. Just when the NPN transistor turns on current passes through it.

The hungarian description says led mosquito repellent

I have a literal thinking mind. Add to that a veracious nature, and I often bug people for me wanting no ambiguity and the precise truth. That's why I liked this person's analysis of the products description as written on its box. Is it this? Or is it that? Lol This is a smart, wise not easily fooled man. He would make a great lawyer or judge... Scrutinising each and every detail to get a full and accurate picture of how and why something works. Truth is, MOST people don't dig that deep to find the truth... So they would never have spotted the contradictions he pointed out.

The new modification still shorts the LEDs. How it saves power ?

@DiodeGoneWild

6 жыл бұрын

Originally it didn't short the LEDs. Now it does. A capacitive dropper supplies a constant current, so the higher is the voltage drop of the load, the more real power it draws. If the load is shorted, its voltage drop is zero. Then the capacitor only draws a capacitive power, not a real power. Some power is still dissipated in the discharging resistors and in the inrush resistor, but the total power is less, because the output of the dropper has nearly zero voltage (just the voltage drop of the transistor, lets say 1V). Simply said, by shorting the LEDs out, the real part of the power decreases. Just the capacitive power remains, but it's not shown by the wattmeter and you don't pay for it.

It didn't yet and I believe it shouldn't even in the future. The average current through the transistor when it's on (LEDs off) is only about 8mA and the voltage when it's off (LEDs on) is limited by the zener and the LEDs.
