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.

Step 2: Assembling the Electronics

Assembling the Electronics
Assembly is really easy and quick. First attach the LED to the switch terminals and then attach one leg of the resistor to one leg of the battery snap and to the switch terminal. Then attach the other battery snap wire to the other switch terminal. Try it out. If it does not work, trouble shoot. Make sure that the LED is the correct polarity.

Step 3: Drill the hole

Now drill a hole in the lid of the jar that matches the diameter of the switch. Then unscrew the face plate of the switch, put the toggle part through the hole and then screw the faceplate back in. Then drop the electronics back in and screw on the top and try it out. It should light up and change colors. If you have questions of comments please feel free to comment.

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)  COMMODORE646 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)  COMMODORE646 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...|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50
joejoerowley (author)  COMMODORE646 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 :)

Here is the proper link.
$50.00 for a flashing RGB light? Thats crazy!!!
joejoerowley (author)  ghostrider19997 years ago
You get 100 of them :)
Well now, thats more like it!!!
joejoerowley (author)  ghostrider19997 years ago
Thanks for getting back, I also deleted my link as to not direct someone to the wrong link.
joejoerowley (author)  ilovetea7 years ago
Sure. Thats very nice of you. Thanks If you have any questions feel free to comment. Thanks again.

Actually these are the wrong LEDs. These LEDs have 4 pins. 2 for power and 2 for controlling the color so you can change to what ever you want when ever you want. The LEDs I have only 2 pins for power and they chose the color. They always start as Red and then go to green and blue and then combo colors. Ok about the anode and Cathode The Anode is the longer positive leg of the LED and Cathode is the shorter negative side of the LED. LEDs can only function this way and will not light the other way, so if you hook it up wrong it will not light. The good thing is that if you hook them up the wrong way they won't be destroyed. So there is a 50% chance of putting it in the wrong way. Here is a chart off of wikipedia I jacked :) sign: + − terminal: anode (A) cathode (K) leads: long short exterior: round flat interior: small large wiring: red black

If you wanted, I think you can buy frosting agents that would make the plastic more translucent. Or, lining the jar's inside with some sort of thinnish paper might work... not sure, just ideas here.
joejoerowley (author)  Geoffrito7 years ago
I just found the jar like that. I think you can buy them like that. In you can't I would try to frost it some how. Maybe wax paper would work as a defuser. Just stick it in the inside. I don't good luck.
spray the inside with spray adhesive and pour powdered chalk into it. That aught to frost it!
joejoerowley (author)  redskinsjbs7 years ago
Interesting Idea. I dont know if the adhease wound stay on the inside very well. Let me know if you try it. OK?
ok, definitely

This is good. I've only started to hear about these RGB leds recently. I'll need to experiment with them
