wow, this is great! Very clever use of the film canister.
I'll change the bright LEDs for red light ones, and it will be a charm for using in the photography dark room. (or maybe just use bright white ones with a film over them)

I would so make this! but my dad won't let me use his soldering iron. =(

[comodore]

Well, maybe you can make it with your father...
He can solder all the connections...  :)

Having my son make this as a cub scout project... Thanks!

[comodore]

:D Just knowing that some one is also making these makes my day! Thanks! :)

[MADAVEEN]

i made one out of a pill case...thanx for the idea...

[comodore]

Cool! Can you please upload some pics of it! I think everyone would like to see it! :)

[akonichi]

ingenious!

by rating this 5 stars, i bumped up your status from 3.81 to 3.85! .04 difference! great instructable

Thanks for the rate and for boosting my moral! :D

[comodore]

hehe Thanks! :DD

[noah1r]

I think it is cool

[comodore]

Thanks!

Building tip, go to your nearest batterys+ store to buy the battery, they will weld on tabs onto the battery for free and make for easy solder on connections. Don't forget this tip any time you work with disc batterys.

Hmm, didn't know about that! I couldn't find the appropriate holder for the 3V battery. Thanks i will definitely see if they do that! Thanks!

Looks great. I'm going to build it today. I'll let you know which LEDs I used.

[fenris]

Thanks, good instructable, well explained and photographed. I know practically nothing about LEDs but intend to learn. I notice that you use no resistors, nor do you say anything about the calculation of which LEDs to use with which batteries. My question is, do you know a site that would explain that stuff in the kind of language that can be understood by a complete ignoramus when it comes to electronics?

[comodore]

Thank you! Well, I don't know a site, but I know a book, The Electronics for dummies book. I have that book, and it really helped me to better understand electronics. As for the resistor, you don't need one because the battery is 3v and LED run on 3V.

[fenris]

Ah, well, there you see how much I don't know. I suppose I would have thought that LEDs run on all different voltages. Does that mean, then, that if you had 4 of them in series you would need 12 volts? Or that if you put a single LED, or two, in a 12 volt system, that's where you need a resistor? You said "don't forget to rate." You mean vote?

[comodore]

Yes, but in this instructable I connected the LEDs in parallel, that means that I connected all the negative sides and all the positive sides, that way you only need a 3V power suply. If you are more interested in LEDs wisit this instructable.

Thats pretty tight. I think I'm going to try this with Infrared LEDS so I can make a pretty tight wii sensor bar for my computer. Thanks for the instructable.
