Picture of LED Mood Jar!
In this simple instructable I am going to teach you how to make an LED mood jar that looks great and only takes minutes to make.

Step 1: Materials and Tools

Picture of Materials and Tools

10mm 15Kmcd Slow Flashing MultiColor RGB LED-I got mine from ebay. They cost around 50 cents US Dollars depending on the quantity. I bought a couple hundred and got a discount (about 15 cents) from this ebay store.. You can either get slow flashing or fast flashing. They don't actually flash, they just change color.
Proper resistor(s) for your LED
9volt battery and snap
Jar- I found one that is diffused a little
Toggle Switch- I bought a one a radioshack

Screw Driver-
Electrical Tape
Drill and bit that matches the size of the toggle switch.

thanks for info dude !:D

LMAO Your switch has no "Off" just two Ons

No, actually is has to different lights to turn on. The center position is off.
Great Instructable. I would love to see this as a Joule Thief with a color dial.
Can we have the schematic please?
joejoerowley (author)  COMMODORE647 years ago
Yeah, I have been looking into getting a program for it. Also I gave the light away to girl who was very very sick and I don't remember the exact resistors I used. This weekend I will hopefully get it done. Sorry for the delay.
I'm still waiting for the syschematic. Can you please give us? :)
joejoerowley (author)  COMMODORE647 years ago
oh yeah. sorry. I just made a new one. Let me know how it looks. Thanks and sorry for the delay. Joe
That's it? No resistors?
joejoerowley (author)  COMMODORE647 years ago
If you use a 3volt battery yeah, but if use a 9 volt I think you need but don't quote me one this a 10 ohm resistor. Idk. sorry.
Thanks for sharing. I'll find something else. This led is too expensive to be made into hobby, especially if you want to makes severals for the cottage uses. Thanks for passing us the useful information.
WHOOPS, I didn't take a look. 100PCS for colored LED at 34 bucks, not bad. I'll take it. Thanks!
This one's cheaper, if you don't care about size of LEDs, it's 100 slow-flashing LEDs for about $15, FREE SHIPPING!!! The only bad thing is that it's only 5mm leds...


Oh well, I'm gonna buy this as soon as paypal transfers...

joejoerowley (author)  COMMODORE647 years ago
Yeah they pretty cheap.
6 + you need a resister for 5mm leds
ya you need a resistor

Use this calculator to get the resistor value based on your LED specs

Is the link to ebay that's posted below the link to the right or the wrong LED's?
COMMODORE647 years ago
Can we have the syschematic please, since you didn't mention on how many,and what you did do with resistors Thanks :)

This is good. I've only started to hear about these RGB leds recently. I'll need to experiment with them
joejoerowley (author)  Pyrowuzzup7 years ago
Thank you. They are a lot of fun to play with.
Really cool job. Got to try this out if I can get my hands on some RGB's. Nice job! By the way, where did you get the MAKE leatherman? The MAKE store? Just guessing. I am kind of in need of one. :P
joejoerowley (author)  GorillazMiko7 years ago
Yeah, I got it from the make store. I love it to death. I love it so much I take it to school, and give it to a teacher who gives it back to me at the end of the day for musical set design/construction. The coolest thing I have ever done in school is fire a gun with blanks in it as school. VERY illegal! :)
Just bringing a leatherman to school is probably illegal itself. :P
joejoerowley (author)  GorillazMiko7 years ago
Yeah it is. There is a full time cop at my school just to break up fits and he will probably taser me so time. He' s a really cool guy as far as I can tell.

Thats really cool!
joejoerowley (author)  Sunbanks7 years ago
Thank you! BTW I love the instructable you made about the crystal cube. Its great!
I think I might try making one of these if I can find the right LED. If I do I'll post some pictures. :D Thank you!
joejoerowley (author)  Sunbanks7 years ago
Sure, they are kind hard to find if you only want one.
I'll have to look on ebay then...
joejoerowley (author)  Sunbanks7 years ago
Well, how many do you need? 1, 10, 100, 1000? :) I could send you one LED if you would send my 50cents.
Two would be better because a dollar weighs less than quarters....I don't know if my mom would like it if I got random things in the mail from some guy on the internet. Thanks for the offer, I'll see if it's ok.
Ok with my mom I mean.

Well, I don't know too much about circuitry, but I researched the LED you have here, and it looks like the max voltage it pulls is 3.8 volts when using either Green or Blue. Well, I do know that, the more voltage reduced, the more energy is wasted, and put off as heat... So, in using a 9 volt battery, you'd be wasting more than 50% of it. Why not try putting 3 AAA's, or even AA's in a series connection, making it 4.5 volts... Much less energy put to waste, and I believe the Amp Hours would also be higher, meaning a longer battery life. Also, won't heat up as much. Please feel free to correct me if I'm wrong, I'm just speaking out of what I've read.
joejoerowley (author)  Lysol7 years ago
Ok, thanks. Thats a great point. I did'nt even think about using the to 2aa's or 2 aaa's. Maybe I will change it later.
