Easy Led Project




This has a few things thrown in from other instructables to make one. Specificly, led throwies and the led 9-volt battery project. Those are some pretty cool things, check them out. This is a led that stands on its own with a film cannister over it to diffuse the light. Sorry for the bad picture quality, and putting a LED project on here.


Step 1: Whatcha Need

To make this instructable, you need:

1.Some leds(more than one looks better)
2.Watch Battery
3.Film cannister(no cap needed)
5.Eletric tape roll(optional)

Step 2: Leds and the Battery

what you do now is take the leds and pinch the part where to wires meet the top of the led. This will make the led hug the battery. Remember not to clip the led wires. Now put the leds on so they all all pointing the same way. After that, bend the wires so that the whole project stands up on its own. Make sure not to cross the positive and negative wires. After thats done, tape it all up so nothing comes loose. Sorry for the bad picture quality here too.

Step 3: Film Cannister and Electrial Tape

now take the film cannister and push it through the eletrial tape roll. If you dont have eletrical tape, thats ok, all it does is elevate the cannister and helps you not be able to see the leds. Now just place the lighting apperatus under the cannister/eletrical tape thing and you're done!

    you didn't put in any resistors. Those LEDs are gonna have way too much current going through them and blow up.

    Hey genius, you didn't put in any resistors. Those LEDs are gonna have way too much current going through them and blow up.

    ...Which is probably a result of the incredible current draw of two LEDs (I think you used two) on a tiny, tiny watch battery. These batteries are actually meant for memory backup and nothing much else, basically just for the tiniest of current draw. I would suggest two AAs or AAAs, or wire some more cr2032s in parallel (plus to plus minus to minus) so that you get more current. It's like a battery is a body of water, and voltage is its pressure. A 110 volt outlet is like a firehose pumping straight from the ocean, it's high power and infinite, while a cr2032 is a shot glass of water. I wasn't trying to offend you, it's clear that you haven't had the opportunity to learn much on the topic of electrical engineering and I was wrong to assume you would. The bottom line is every time you wire an led you need two things: 1. Significant current 2. resistors to make sure the full brunt of that current is not overloading the LED Because an LED wants to be a short circuit, naturally, and you need to limit the current draw, in short. It will typically get very bright and then slowly dicipate until it burns out. And yes, they do literally burn out, I was short circuiting an LED this same way today with 12 volts and the LED got all hot (That's another thing, check for heat on the LED, it's a sign of too much current) on the legs and after a couple seconds I actually heard a sizzling noise, and the LED was toast. Sorry for being Mr. Offensive, I think this is a much better way to give you positive criticism. Nice work though. -Jeremy

    you could use some of these and create a pretty cool light by putting them in Bawls bottles.

    if you cut the film canister it can be like a jack-o-lantern
