TeaLED: Led, Switch, Box and Batteries (not glue nor solder)

FeaturedContest Winner
A Tiny Led lamp to use wherever you like, don't need electronics knowledge to make it, just cut an acetate sheet with the template included here... add 2 CR2032 batteries and 1 Led (white, flashing red, ultraviolet, RGB slow or fast, 10mm or 5mm).

I have always liked LED's and since their existance, I have been using them in a lot of projects, looking for a small box where to put it, using cheap materials to create a nice looking finished project. After a lot of designs with trial and error, now I designed a template to cut a PVC sheet (acetate/mylar) and made a box for the batteries, the switch and the led, without even using glue or solder.

So here is my first Instructable to teach you how to do it, and use it in a lot of ideas (I will give you some of them). I know that it looks like a kind of led throwie but it isn't (we don't have to throw things, it's better to recycle them), because its designed to put it in an exact place to illuminate whatever you want. You can change the batteries and either add to the base a piece of magnet or some velcro or double side tape, so that you can put the box on any place. The box also has a switch tab so that you can turn it on/off, Hope you like my project.

Simple, and awesome! Was so fun to make and it worked the first time! I didn't have any Acetate so I just used card stock, probably won't stand up as well, but I'm happy with it!

This is excellent - just what I need for a craft project I'm working on. I'm trying to keep my budget low and this does the job. :)
every year for halloween i decorate every window in my house with black silhouettes. last year i found my stash of led's that i bought one year and never got a chance to use. i decided to tape them to a coin battery and then just tape it to the window behind the eyes of some of the silhouettes.

it was a pain in the butt because they are paper and having to retape them every day got really annoying. this is PERFECT for what i want to do...but my question is...will this still work if i reposition the led to the thin side of the box? so that i can tape the box flat to the window?

thank you
tu invento es super, te felicito
how lond would this last?

That depend of the type of led you use.... if the Led are white, blue, red, 3mm, 5mm, 10mm, Multicolor, Flashing..... But I can tell you that at least the led will light 5 hours and more.... I use them (and sell them) in all kind of Parties, insed candles and other stuff..... and they light all the night :)
long oops

nice led, very instructable and inspirational ... cool stuff buddy ... one thing you should to know is: your post is the #1 reaseon for me to join http://www.instructables.com ... again, thanks becava ... nice to know you :)
becava (author)  miphz3 years ago
I love you comment miphz..... I hope INSTRUCTABLES team read this one, so they know my instructable make more poeple to join their page ;)

Thanks again miphz :)

i'll probably use this to make a battery box with a switch at some point. it is simple as most brilliant ideas are.
When i can't get acetate to play with i laminate an a4 laminating pouch and it is about the right thickness and flexibility.

Thanks missgroves :)
CR2032 Button cells are 3V no? I've never seen an LED that runs straight off 6 Volts
becava (author)  Ben The Builder3 years ago
I already explain this to someone else here..... yes, coin baterries are 3V.... Leds need 4.5V so you can light at 100% a led with just 1 coin cell..... so you can use 2 batteries (1.5 volt) and use a resistor to light a led...... well, here is why I use 2 coin cells: Coin Cells Baterries have a lot of resistance, so you can use 6V without danger..... try it, you will see.... the led will not burn, and will light at 100% and also it will light a longer time than just 1 battery.... hope is clear now ;)

 Clever, I could rig my camping tent with these and light it up at night. Thanks for the instructable!

Add velcro squares to the base of the TeaLed  ;)

WOW
becava (author)  scratchr4 years ago
Thnaks for your WOW :)
how exactly do we open the pdf? i think u use a software from adobe that  hav to pay for
can u just post an image of the template on google or sumthing....
also where did u get the plastic?>
becava (author)  Fireslash8924 years ago
You can download the PDF reader from adobe homepage, is free......

Where to get the plastic? read the other comments here, I'm already answer that question....

And thanks for the message  =>  "anyways ur a genius...."
Where do you buy sheets of acetate?
becava (author)  phillipjmerrill4 years ago
I'm from Mexico, and I buy it in stores that sell sheets of differtent kind of plastics, you can also try in craft stores.

Absolutely genius idea!!!! Any idea what sort of average battery life you get with this??
becava (author)  Esque5 years ago
That's depend the type of the Led: a blinking red 3 to 4 weeks, white or blue or RGB led 6 to 8 hours , red or yellow or green 10 to 14 hours. All Leds consume different current (mA) each other, the brighter it is the less battery life you get.
Tommyhzy becava5 years ago
Ummm... I think you are very knowledgeable about this subject so... I currently have an advanced "TeaLED" system, it runs on 2 Maxell AA batteries, in series, and that is connected to 4 RGB LEDs in parallel. I think that means that 3V will be given to each LED, but the batteries' power will be split. So how much time do you think it has? (By the way, it's enclosed in my acrylic iPod dock which i fully made myself)
becava (author)  Tommyhzy5 years ago
For AA batteries I will use a resistor for each Led so you can have more time for the batteries, and the only way to know the time is to buy new batteries, turn it on, start a timer and keep looking until the led don't bright, stop the timer :) Thats because all diferent brands of batteries have a different quality and mA capacity (same voltage, but diferent current).....However I think they can last a week using a resitor with the leds
Tommyhzy becava5 years ago
Oh, my LEDs have their built-in resistors, because they are RGB LEDs. Anyways, thanks for the advice, although I won't want to set up a several-week timer anytime soon! :D (And i turn them off when I'm not using them...)

Is it okay if i use 1 battery?
becava (author)  BraisedDuck5 years ago
You can use 1 battery, but have to change the dimensions of the template, and don't forget that the led will have less time and brightness.
Tommyhzy becava5 years ago
You don't really have to change the template too much, a Canadian Nickel is almost the EXACT same size as a CR2032 battery! :)
becava (author)  Tommyhzy5 years ago
Well, I'm from Mexico, I only know Batteries from Mexico, USA, Taiwan and China :) Don't know the size of Canadian Nickel, but for the TeaLed Box to work need to have the exact dimensions, even 1 or 2 milimeters error will make the switch to fail
I said that so you could use that as a conductive filler... :D
