This is a solar garden light that suddenly stopped working. Why not take it apart? :)

## Step 1: What's Inside?

I've added notes on the pictures to explain the components, You can see them by hovering your mouse over the pictures.

Solar Panel

1 LED

Useless short legged resistor

3 small screws

Do you like taking apart electronic devices? I've made a collection of a couple"What's Insides" If you're interested:

<p>That &quot;resistor&quot; is an inductor. These devices use a voltage booster circuit to drive the LED, and the only part not inside the blob is the inductor, otherwise known as a coil.</p>
Does that mean that the resistor helps to higher the voltage?<br>Is that even possible?<br>
<p>As I said, it is not a resistor. It is an <strong>Inductor</strong>. A circuit with an <strong>inductor </strong>can indeed raise voltage. This is how those cell phone chargers that use 2 AA batteries work. They take the 3 volts from the batteries and turn it into 5 volts for the USB output. Look up &quot;Joule Thief&quot; on this site or Google and you'll get plenty of examples.</p>
<p>I've got several of these that are slowly dying mainly because they are not very water proof,I told my wife they have salvagable parts now I'm vindicated /</p>
How do you clean solar panel?
<p>If you want to charge batteries that have a higher capacity, You'd have to have a bigger solar panel that can supply more current...</p><p>The resistor is useless for me because I wasn't able to salvage it because the legs were really short</p>
<p>Wow so simple. No charging circuitry or anything. Hmm. makes you wonder if larger batteries could be charged in that simple way. I don't think the resistor is probably useless. I really dont know what it's for, but it's got to be for something. Maybe limiting the current charging the battery or acting as a buffer between the battery and the led so as not to stress it. I dont know. At least in the minds of the manufacturer there had to be some logic to justify the additional component.</p>
