4.7W insect zapper from Lidl - test, teardown, experiments 

Danyk's cat is a girl.

so he has cat as gf... cf

I'd have to leave my Budgie at home lol

A replacement tube happens to be packaged in a zapper case, most likely cheaper than just a separate new tube.

@@pe1dnn even old bug zappers were that way. You could pick up a new bug zapper for $19.99. It had two tubes in it. If one went out, a replacement was $18.99. I call that the bug zapper theory. When parts for something cost almost as much as the original product, if not just as much, or more in some cases. I agree with the original commenter. How can something be environmentally friendly if it's designed to be thrown away after a single use? They would rather just take more of your money and have you buy a brand new product than spend less repairing what you have.

Plus, those tubes contain mercury.

yes, but lable says "for indoors use only"

you could plug it into outdoor socket while keeping device indoors

I can't imagine using insect zapper "outside in the rain". This is just super deadly...

@@DimaDeKatz It's have high voltage but current is very low.

@@DimaDeKatz meh it isn't

Yeah, of course, but it's a false dichotomy. It's possible to have both.

What a cool idea!

Thanks, yes I think so too😁. It could report hits to a web server additionally. Then you can turn on the mosquito lamp in the bedroom, leave and close the door and follow the results on the phone. Maybe graph of hits per minute. But a counter is a good start.

Awesome!!

The added stuff could be hidden inside the lamp or outside depending on how much available space there is. In the lamp in the video it could possibly fit inside. The computing board could be a Raspberry Pi or an Arduino or something else running on power from the mains coming into the lamp using a 230V AC to 5V DC conversion board or a board from a 2A USB phone charger. The display could be an LCD using I2C, only 4 cables connected to the GPIO pins of the computing board. The data from the lamp circuit could be sent in to the computing board through its GPIO pins. The big question is where in the lamp circuit it is optimal to read and how. The current limiting series resistors at 10:43 has 6,5V AC when grid is not loaded and 143V AC when shorted, possible read point, but how to make it readable for the computing board? And some lamps maybe don't have this. Would be nice if the setup was applicable to most bug lamps you'll find in the nearest supermarket. The grid is an open circuit when no insect is present and a closed circuit when one is. Could read this somehow, but that part of the lamp circuit has very high voltage, in this lamp 975V. There is also some safety discharging resistors that seems to be common in this part, seen at 11:10, maybe by measuring current changes on these. I guess it should drop if an insect is present. Or maybe by not entering the lamp inner circuit at all, just measure the watts of the whole lamp. If it changes, then an insect is there. 😁

@@dotpointer > Or maybe by not entering the lamp inner circuit at all, just measure the watts of the whole lamp. If it changes, then an insect is there. 😁 Yes, that is the easiest. I think a wemos D1 mini (ESP8266) Is perfect for this due to wifi + gpio + small size and consumption, plus short boot time.

They're afraid of somebody trying to replace the lamp, getting a shock and suing them. Environment friendly is just a fashionable word that every product has to have on it.

I enjoy watching mosquitos explode. Good job! Fred

I use 15 thousand volt

@@309electronics5 this would definetly sparc at the distance of the wire. For 15 kV you need a distance of at least 15 mm between the wires, and you need expensive caps that would be very big....

Welcome to the channel.

Nebyl to spíš odporovej kabel? Neumím si představit, že by kabel měl dostatečnou indukčnost, aby nahradil železnou tlumivku.

They used to employ this type of "resistor/inductor" cord on old tube AM radios, made back in the early 1900's. The mains power cable was actually necessary for them to work and not blow up. Fred

@@DiodeGoneWild když nad tím přemýšlím,je to dost možné, fakt je, že indukčnost to muselo mít celkem malou. Každopádně po výměně za obyč už to světlo nikdy nefungovalo.

Have you ever seen Danyk's Tesla coil? If he improved this it would probably kill a lot more than just the errant mosquito! Fred

of course :)

All gas discharge tubes are negative resistance devices AFAIK.

@@Broken_Yugo Yes, but they will only exhibit negative resistance characteristics at specific bias currents.

Now that is genuinely funny! Fred

I don't think it's public. Better check his website and send him a email

@@jb5631 Thanks

Few seconds later I realised it, but I left it in the video to show how stupid this graphic design is ;).

You can't swap those capacitor, the 47 nF one is only rated for 630V.

@@koharaisevo3666 True. I was assuming they are rated the same. My bad. You are right. Thanks for the correction 😊.

In a dry room with a plastic floor, rubber crocs and all grounded metal objects over 2m away, there's virtually no way I'd make contact with ground.

@@DiodeGoneWild I see. So its like infinite resistance? Thanks for explaining to regular people :)

Its from the land of angels and fairy dust... Most likely China. Fred

stop whining then

That's dodgy!

That is a dumb way to die.

sewper dodgehh 💀
