I bet when Bob the accountant tried it he messed it all up. Hey Bob change out the battery.

Just show us! Omg

50 shades of the dominator

The voltage is actually determined by the battery voltage and the collapsing magnetic field in the inductor (it's not produced by the IC itself). The IC is just switching to constantly induce back emf in the inductor at a certain frequency. This voltage is then high enough after the collapse for it to make it's way over the LED. The LED is thus lit by pulses at the same frequency as the oscillation, it isn't constantly lit, our eyes can't tell the difference.

LED's don't have linear current draw in relation to voltage, however they still are voltage dependant, despite some random Americans online pretending that they are some miraculous device that runs off pure current (not even something that exists in this world, there is no current without voltage, you require both for there to be power, they don't exist on their own). LED's will require a certain voltage before they start conducting, and indeed you do need to raise this voltage to a certain level to get them to draw properly, meaning they are dependent on the voltage, but just not in a linear way (so going a little over can mean burnout, where as in linear relationship electronics it won't). For example an LED with a starting forward voltage of 3v, if connected to just 3v, will be dim, however if you increase the voltage to 3.4v it will be bright. The LED does need a certain voltage, because it does have a resistance that determines how much current it can draw (even if not linear). The physical resistor in line has a linear relationship, so we use that, so even if the voltage source is a mere 0.2v higher than usual for some reason, or if the LED's resistance lowered a little for some reason, neither result in the LED burning out, because the resistor itself will limit current depending upon voltage in a predictable way, meaning only a certain amount of current can get through the resistor regardless of what the LED is trying to draw.
Oh and yes, it will burn out if you try to run it at a massive voltage, there is another misconception that you could run a 3.2V LED at like 100V, just as long as it's only drawing like 20mA, this misconception created by some Americans on internet forums claiming that it runs purely off current and that voltage doesn't mean anything. This is again false, increase the voltage massively, and the physical power increases, and the LED will burn out instantly. Wattage is still determined by the voltage and the current, and LED's wattage is a product of both, it isn't some magical item. However it is true that a 3v LED would survive longer on a 5v supply and 20mA limiting resistor, meaning the LED would only be drawing around 60% more power than it should, when compared to for example just running the LED at 4v without a resistor at all, because of the LED's exponential gain, it would burn out after just a minute or two and be drawing 300% more power than it should.
However this concept has become muddied by some Americans who don't quite understand electronics properly, filling those forums on the internet etc.


As far as upgrading the unit, you will actually need to replace all 3 components, meaning the battery should become a 600mAh at minimum, the LED should be increased to a 30mA capable LED, and the solar panel should also be another 3V one, but with at least 3-4x more current than the current weak one. Because the tiny mA solar panels included are not powerful enough to fully charge a 600mAh battery for example, they are purpose built just to be big enough to charge the crappy 200mAh battery and run the weak LED for around maybe 6-7 hours during night.

The IC itself doesn't need to be replaced, because if you look at the datasheet it can handle more than it's used for in these little lights, this is likely because larger solar lights use the same IC, these IC's were purpose built for general solar garden light purposes, so they are used in underpowered and higher powered units.

Home Depots $5.88 solar garden lights are pretty bright. 14 lumens. I use rechargeable 2000 amp batteries that I can charge when its cloudy. They last longer.

Can you use a larger capacity mAh battery AAA in place of the 200 one? I have 350mAh 1.2v batteries in my solar lights that are sentimental. The ones I can buy on AMazon are 600 mAh. Will I fry them if I replace the 300-350 ones with the 600 ones?
I THINK they would be the same size (AAA)... thanks in advance for your help

The wolf of Swingthat

you removed the resistor wouldnt that make the LED more likely to burn out as the voltage is too high?

I recently got a pack of 5 lights from Sam's (their brand) for like 18 bucks and they are pretty bright! But after a couple of nights, but they began to get dim around 3 o'clock and shut off while it's still dark(so, from 8pm to 4am, not a bad run). We live in a super-high UV area. They came with a 800mAh battery. I think of either switching to a 2500mAh battery or soldering on a holder for a second battery in parallel (under the cap, there's lots of room), or maybe doing both. The goal is for them to last until the rising Sun turns them off. Are these ideas realistic? And which is better? My concern that the solar panel won't charge both batteries or a single bigger capacity battery sufficiently, so it would be an exercise in futility. Your thoughts? I'm not really an electrician by trade.

Which should plan to use: 33uH 1 watt , 47uH 1 watt, or 68uH 0.5 watt inductors --which? I guess, my real question has to do with wattage.

Nice light.👀>share4.photo/PostLight?113  Doesn't light up a very large area but it's just right aesthetically in my landscaping. Instead of bolting down to concrete I drove a steel t-post (fence post) in the ground and slid light pole over it. This was way quicker and easier to install this way. Know what's underground before driving a post in the ground though....

What's with the weird gloves? Would be nice if you took the hiss out of your audio and cut the video down to only show what's important. FYI
Also feel the amount of time and material it took to do this you could have bought a better unit. Unless you're just trying to learn electronics.

Nice video and explanations. But why did you use Ni-Mh batteries? I thought Ni-Cd was better suited for repetitive rundown/recharge cycles like in solar garden lights. Couldn't you have used higher mAh Ni-Cd batteries and gotten the same effect?
