This is not a urinol. I Feel the need to say that because it sure as hell looks like one and even in the eBay listings when I bought this about a year ago, it also had that sort of look to it. Here's what it looks inside, and certainly if you put it in a public restroom, people may urinate in it if it was put at the right height. I'm not going to test that.

Let me plug it in and you can see if you can work out what it is I'll plug it into this the anti- Testa and uh for its for rating it's a very ungenerous. uh 2 wats 1 point oh like you can't even see that? Hold on I move this in. uh 1.9 watt um current 33 milliamps power factor a measurable 24 Um, interesting. It does claim that it is for wat two two wat ultraviolet tubes I'm not so convinced about that.

Let me just, uh, unplug this device and get it out the way. and then we'll pop the lid off this and take a look inside. This incidentally is a glue trap. It's designed to attract insects.

You mount it up high so the light is shielded from your vision just for convenience. And it takes these sticky mats. I Say it takes these sticky mats. I Don't even know if you can get spares for it, but the idea is you peel this coating off and it's got a sticky layer.

The insects get attracted to the light and then when they get bored, their little wings want to rest. They land on the mat and then they stick to it out ofs side and then perish horribly. As happens with these type of things, the back of it is very stylish actually. Look at that, all these of slots and grills.

They've missed a trick though. This is the cable entrance here. it would. There is another option here, but it would have been nice if you could actually dress the cable across and bring it out the other side.

anyway. I'm going to take the screws out of this. so the sticky mats are an alternative option for the high voltage insect zappers. And they are favored these days because they don't make those loud electrical zapping noises and uh, huge quantities of smoke.

See? This is why I've not made this video about this before. It's huge. It is a monstrous thing, but the sticky traps they instead because they just basically trap the fly and hold it in place. They don't blow the bits of the fly all over your food apparently, so that's why they sort of come into favor.

It's also quite disturbing when you're in a quiet area and one of the zappers gets a big insect and then it's just basically zapping and sming for ages. I Don't know which is the most? Humane Probably the sticky trap. Not really sure. do people treat insects in a Humane manner.

this? this does not reach down there. That's disappointing. Uh, let me see. I Can find an alternative screwdriver that might reach down there.

There's one. It's a universal old Diamond tipped screwdriver courtesy of Phil who said this a gift? Thank you. Phil Is this going to come? Partner: Oh, it is coming apart right Here We are in. screws scattering everywhere.

so let's see we can find out. Oh, there is a little circuit board here. Let's see if we can brighten this up a little bit. A little circuit board down here which will pop out.

It's very basic looking. H Then it's got the two cables going out to the oh that even unplugs. That's quite nice, isn't It seems quite well made. Um, then those wires go out to the tubes.

How do the tubes come out? So I shall? uh, I should just take everything apart I'll take the pictures as I usually do and then we can scrutinize this. I'll tell you what this looks as though. unclips. That's quite good.

Oh, that's better, isn't it? That's a a much better result. Um, anything happening with these. Do these. unclip from the back.

Well, they are kind of clipped in. Hold on I shall just unclip them. Oh, that's that doesn't feel right. No, that just feels like squishy plastic to be honest.

which may be how these actually go in. Maybe these just slide in. Or maybe I just crunch it up and break it. Oh, there we go.

So there's the LED strips which are just slid in. Okay, right. I Shall reverse engineer this and we'll take a look at the circuit one moment. Please, Reverse engineering is complete.

Let's explore. It is a Symol capacitive dropper. Let's Zoom down this to get a closer look at this capacitive droper. goodness.

So the power comes in on this connector here and there is a fuse. Then there's a uh, current limited capacitor and by current limited capacitor I mean that in each half cycle. Uh, it allows a portion of current to flow batter and forwards. that gets rectified by this bridge rectifier.

uh, used to charge this capacitor here up and uh, then drive the LEDs There are some resistors. there's mainly discharge resistors as I'll show you in the schematic and then there's a couple of series resistors with the LED strips like these. let me grab the schematic and show you what's what. I shall Zoom down just a little bit more.

This is where I usually over Zoom Badly, here's the incoming Supply There's the printed circuit board fuse which is just a thin track. There's the standard X2 Suppress capacitor 470 nanofarad and rather pleasingly cuz this is good cuz sometimes they just put a single resistor across it. They've got two 220k resistors in series and that means the dissipation which is low anyway is spread across them. but also it means that the voltage across them is lower than it would be if it was just one.

There is the bridge direct fire which converts that alternating well. This allows that pulse current through in the positive wave and then the negative wave so that Uh rectifies it and charges this capacitor. Unfortunately, that is a 47 micard 63 volt capacitor being used at 73 volts. Quite a high voltage.

It's above its rating, but but it works. I think 100 volt capacity would have been a better option for there, or if they wanted to allow for everything going wrong and everything going open circuit. they could have used uh, uh, 400, a 400 V pter when uh, the LEDs go up circuit in lamps like this and I don't think these ones will really suffer much because they're being run at low current. When that happens, the voltage flies across that capter right up to pretty much Peak Main's voltage.

and uh, but it's current limited so even if it is an underrated capacitor though, it will vent and puff up and pop. It won't necessarily do. it won't just go bang. That's the the main thing there.

So that capacitor has its own little 220k discharge resistor. Then there's two 100 ohm resistors with two connectors going out to the LED strips and each LED strip has 23 LEDs with a voltage across them at 71.4 volts. and the current because I measured the voltage across the resistors at 1.2 volts, the current is 12 milliamps. Now if I bring in the Kink calculator, we can work out the voltage across each LED.

So 71.4 Vol Uh divided by the number of LEDs is roughly 3.1 volts per LED, but that is only at 12 milliamps. It would be a bit higher if the Uh current was higher. 12 mamps is quite conservative for this. The LED strip itself has a connector at one end and it's got a bus bar system going right past so that it can actually Bridge onto other ones.

It's pretty much a standard LED strip that you might find in some of the Uh strip lights, but uh, the LEDs themselves are all just in series. You may see that in the back here You' got these big bridging links and there's the positive and negative going the full length and Uh, one end is connected to one of those rails, then it runs through all those LEDs and then it connects the other Rail and uh, they can just extend that on if they want, but in this case, they have just basically used Uh two in parallel with their own resistor each to cut sort of allow for any slight voltage difference to even the current through them all. It's very straightforward and um, if anything, I'm surprised that they they rated these at about 2 watts per strip, but they ended up running it at one wat, so it is going to last a very long time. If anything, for the given, you've got sharp Points of Light here that I thought would attract the insects better I wonder if it would have been better if they'd used clear covers instead of this diffused one that just creates a softer glow and might have less reach than uh, the directly viewed LEDs But maybe they were just going for the fact they're pretending this is are basically uh, using fluorescent tubes just like the traditional ones.

The sticky mat itself I don't know if you can get spars or not for that particular model. Is it sticky? Let's T it? Yes it is. It's sticky. Uh, but you could improvise yourself I'm sure you could get other sort of A4 sheets this stuff and just lay strips in if you wanted.

But there we have it. the strangely urinal shaped, um, low power ultraviolet attracting sticky insect trap. It's not bad. It's quite a nice construction, nice circuitry and just kind of slightly underwhelming.

And the spears don't seem to be readily available. but other than that, pretty neat.
