yes solar cells output DC, you need the diode to prevent electricity from flowing from the storage tank.(capacitor in this case, could be a battery.) An LED is a diode, current only flows in one direction through a diode.

you want to when you can buy a 3 dollar (US) solar garden light that does the same thing?

The mistake many poeople make is thinking that adding the Joule Thief (or any other power dissipating circuit) is going to "make it more efficient." The typical conventional JouleThief is about 50% efficient, which means half the power is wasted in the JT. You are better off using the simple and less power wasting circuit that you have in the video.
Adding a super cap / ultracap of more than a hundred farads will give the storage capacity to run the JT for several hours after darkBut why would

@seennlisten, uF.

@xear3d2009, it's a germanium diode.
-
What is the voltage required for the LED?
-
What is the voltage on the LED? How many volts are required?
-
which capasitor do i buy to make a solar usb charger, is it 470 mf or 470 uf?
-
umm i don't think u need an LED if ur allready in sunlight!
-
may i ask..is that a resistor above the capacitor?
is that a solar panel from a calculator?

Solar Joule Thief HEWEY Boxedby Lidmotor2,450 views
Nice work!! (5 stars!!) Once you add the joule thief circuit you will be able to light a bunch of leds with it. Then, maybe face them toward the solar cell and see what happens. I have always wanted to try this and bought 3 good size solar cells but have not got around to it yet. I don't think I can make it self run but I may get close. Keep up your great work here.

Bill - Cheers I have a 12W Solar Cell I charge my battery bank with 12v 42Ah, Im going to scale this up when it works....
Did you find a Rheostat?
