Two Solar lights. one is real and one is a clothing one of both sort of lights but this one is a no kerolite and I've already made a video featuring this now now Kara was I say was because they seem to be on Hiatus at the moment it was a light that uh was developed for third world countries where they were using kerosene lamps hence the name Nokero. Uh I featured this in the video at the completely wrong time I did it during the pandemic which was just not a good time to mention a product like this because I believe some people went to buy them and uh at their difficulty supplying them at the time I feel a bit guilty about that and this is a generic clone based on the look from China and the differences are significant I've I don't know if you can even get these online anymore I Deliberately avoided featuring it because while this was still an active product because uh, I didn't want to actually basically promote an alternative that is greatly inferior. Anyway, so it's not so good.

This one uses one, two, three, four, five, Six seven, you can barely see them. Uh, Sun Power solar panels which are basically reverse lit solar panels. Super high quality, super efficient, and it's got a single LED inside a drainage hole. This is good that I wish all solar lights have drainage holes a single LED and then it's got a life peel four FM member correctly.

Yes, it is a live Po4 and very odd circuitry to actually drive it. The video about this is quite interesting. It's unusual. There's a a particularly strange feature that if it detects its overcharging lithium cell, it turns on the LED to kind of drain the charge or use that energy up.

It's an odd way of doing things, but the video is mainly about this which does not have good quality solar panel cells. It's like the generic Garden solar light ones. This one had a very simple operation. You had a low, you'd high and you had off and it wasn't turned on and off by sort of.

If you put it out in bright light, you could still leave the light on. It was just basically so that you had more versatility in using it because it is actually designed for charging sunlight and then using for Illuminating indoors at night, this one seems to have a standard solar garden light. Vibe Going to it's got oh, they're loose. Uh, it's got five millimeter LEDs and it's got a switch that can switch between I'll cover the solar panel, six of them being lit and just one of them being lit.

Um, so let's just get straight into it and take a look inside. I've got a feeling that this is just going to be a standard Garden solar light with a switch between either six LEDs in parallel or one on its own just for visual effect. I Don't think it's really going to be anything up to the Sim level as that one it does at least have. uh, decent enough double ESL one thousand milliampere.

Well, you believe that or not. Nickel Metal Hydrate uh is is. you know that's a debatable thing. Interestingly, I'm seeing that although the middle LEDs just actually sat into the plastic with the leads folded between two circuit boards, the other LEDs are mounted in two separate socket boards here.

and I'm guessing that the reason they're two is just to leave a bit of extra space for that cell to Gwen. So I shall pop the circuit board out the main one here, which, uh, looks as though it's got all the circuitry on it and I'm guessing, oh, it doesn't come out that easy because of that. I'm guessing it's got yeah, oh, it's actually I'm wrong. It's actually got two boost circuits with a different size.

No, they've got the same size and doctors, that's a bit weird, right? Say what? I'm going to take this out I'm going to reverse engineer and we can actually explore it one moment. Please, Reverse engineering is complete and it's kind of strange. Let me show you this: It's effectively two completely separate solar lights in one package showing a common nickel metal hydride cell and the nick of metal hydride cell goes straight to a two-way switch. Well, let me show you here's the positive connection from the metal hydrated cell going to the center contact for two-way switch, and then either side of that switch diverts to a separate solar light.

The solar control chips have a common solar panel fitting them and it's just looped between them, so no matter which way it's switched, it can charge that. What would it be nice in here would have been a little diode, perhaps even just a cheap silicon diode that would have actually put a charge into that even when it was switched off. It just seems that it would suit that product better. However, there is a strange thing one of them the iron tends to setting has six LEDs the low intensity setting has one LED but they both get the same size of inductor 47 micro Henry which is going to be about eight milliamps flowing through the LEDs I Would have thought that given that this is supposed to be two modes, it's supposed to be uh, fairly sort of bright mode for work use and a low level mood for just ambient use I Thought it's basically given this as diffused they could have used perhaps uh, Straw Hat LED here and they could have used a 220 micro Henry inductor and it would have just passed about 2 milliamps through the LED series got much longer run time.

This one they could have actually decreased the value of the inductor to 22 micro Henry and it would fit about 15 milliamps through the LEDs which would have given much greater intensity for General work use Things worth noting: a brief description of how this works in the first place. These are solar garden light trips. They have the facility to basically charge the Nikometi hydride cell when it's connected by having a little diode between the solar panel and the positive, and it also monitors the voltage of the Uh the battery to determine when it should cut off without over discharging the battery. This is quite a clever little chip, but when it detects that the solar input has reduced below a certain level, it starts pulsing this output when it pulses.

The output on this inductor has a magnetic field put in it and normally the voltage from the nickel metal hydride cell is a maximum about 1.5 volts at full charge and it can't find its way through the inductor and the LEDs so the LEDs won't light. However, when that is pulled to the zero volt rail, this end is positive. At that point in time, it's connected to the nick of metal hydride cell and it pulls this end negative, but then it turns off again and the magnetic field collapses and this end then goes negative and this goes positive. and that effectively adds some series with the nickel metal hydride cell and it passes.

current. Increase the voltage enough that it can pass current through the LEDs and the amount of energy stored in the inductor at that point in time is what will basically go towards lighting. LEDs The LEDs There were two circuit boards. There was the main PCB which had three of the elite of the six LEDs on it, and Uh, one connection for the single LED and then the auxiliary PCB had a common negative connection from them.

All right, negative. or I could write zero Volt or I could write ground. So many different things that they used to describe that, or indeed, the little the little block like that. That said, all these common things used for referencing the same thing in a single real Supply but um, I've kind of forgotten I was talking about and now I'm gonna say that.

All right. calling zero vote real and uh, so only needs one connection, the main PCB for that Led and a another connection. so there's only two wires going across. negative uh, and then the uh, the one for the three LEDs Here, the other one comes from the main PCB because it's the LEDs just tapped directly across them.

Uh, that is more or less it. That is what you might expect. It's a generic Chinese clone, not really fantastically designed. It's just a cheap copy lookalike that has some of the similar functionality.

Maybe it's interesting enough. the case could be repurposed to make a more functional light, even just actually getting rid of one of the sides and actually doing that little dive modification and having a a different LED in there. maybe even a higher power one, But that's it. That is the crappy clone of the Nookero light.

It literally just made to have similar functionality ish, but uh, just been made cheaper and that's really what they do. Um, and there's not really much else to say about it. So I'm hoping that No Cara is still on the go and they're going to keep making things I Don't really know what's happening with No Cara at the moment? Um, but this light here I Guess maybe it'll appear randomly on eBay from time to time, but it seemed to have its Heyday when it was basically just to provide a cheap alternative to this fairly expensive, but justifiably expensive. um, proper working night.

But interesting things: The No Carolite was quite interesting. this one was less interesting.
