Story:
I saw the other pics of mint tin lights, so I thought I'd post mine. To do it used a 9v battery. then drilled holes for 6 LEDs in the top, and for a switch. To put the LEDs in i shrinkwrapped each end and threaded the wire through to the next hole. There are two parallel sets of 3 sequential LEDs.

People like different things so lets keep the comments professional and if possbile encouraging. That doesn't mean that you shouldn't tell what you really feel about the mod but usually that means more than one word.

As someone wrote before... Diodes are not lamps, besides with a scheme like that I would personally used 2 resistors to force the load to be splitted equally. If I had seen 2 resistors in that scheme it would have been a 5/5... now it's a vague 1/5 + recomendation to read up on what a diode actually is, and in what way LED diodes differ from diodes which doesn't emmitt light. I'll give you a little help, read this http://en.wikipedia.org/wiki/LED and take special care at the physical function part, and maybe you will realise why you want that resistor.

the power of the 9v battery shared by six LED's will not make them short out, nice one! 5/5

A single LED needs a 1000-ohm resistor wired in series if connected to a 9-volt battery, the resistor limits the current and prevents the LED from burning out. However a series of multiple LEDs can be connected to a 9v battery in place of using a resistor. Check the voltage rating of the LEDs you are using and use enough LED to add up to just over 9V.

Usually u would bought a flashlight.

yea, but only if there is a greater voltage input than resistance right? a system can be stable with 9v resistance and 9v direct current input right? what would be gained by adding non-light emitting diodes and resistors?

emerson27.03.2006 22:42
LIGHT EMITTING DIODE--and it still works without resistors, but the LEDs will probably burn out or melt

x27.03.2006 15:25
and LED is a resistor isn't it? Hence the 3V resistance of each LED? I dont get whats not finished about it unliving. if it works, it works.

unliving27.03.2006 01:25
so that means the project is unfinished...post it when it`s finished...2/5

it isn't turned on cause diodes without resistor(s) can make the battery explode.
Some of us can't see the difference in diode and light bulp.

....why isn't it turned on...
