Our most popular item on our display at Maker Faires is always the Rainbow Jar. One customer has already replicated it so we thought we'd share how we made it so you can make your own!

Step 1: Getting Started - What You Need

This is all the stuff we used. 

What You'll Need

50cm of Addressable LED Strip
Plastic Sweetie Jar (found them on eBay)
Arduino Uno
Pin Headers (UK)
Stripboard (UK)
Rainbow Wire
5V Power Supply
omething to diffuse the light - we've used RGB LEDs!


Soldering Iron and Solder
Wire Strippers
Craft Knife and Ruler

All of the links are to our site - in the US you can get everything from Adafuit or Sparkfun

<p>Wonderful. It's a lovely project and there is lots of things you can do to customise it. Here is my version: </p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/X4BDwZSmR-I" width="500"></iframe></p><p>I haven't uploaded the code yet and I will give a full description on my website too. The short version is that I used plastic beads instead of tri-colour LEDs, Pro Mini instead of an Uno and added a bluetooth&gt;serial adapter so I can control it with my phone. I'll release the Android app and the rest of the code soon.</p><p>Thanks again for this instructable, I had a great time working on this project! :)</p>
<p>Get it written up and enter it into the lamps contest! Would love to see it win a prize!</p>
How many leds did you use for this setup?
It was a 50cm strip so 30 LEDs doing the lighting then probably best part of a 500 bag of the RGB LEDs - which is probably a little excessive, but we have a whole heap of LEDs!
can you give me a link where I can purchase the specific RGB LEDs you used please :)
It's simple,but it 's creative to use a jar,I am thinking about make one to give my girlfriend as a gift.
nice really great looking
This is really cute!! ( I know most guys don't say cute, but I'm not a guy) lol I did something like this but used mini battery operated xmas lights. Banded them up and stuck them in the middle of the glass vase then added glass stones all around them from the dollar tree. It turned out real pretty ( and cute) lol
do you still have it? Would be good to see a pic!
I do still have it, it's in one of the Christmas boxes stored away until Christmas decorations come out.. if I remember ( hard tellin at my age) I will put a picture up for you :)
couldn't you just hack a led Christmas light set and chuck that in? looks good nice idea
I'm sure that would work of a fashion. These LEDs are addressable so each can be a different colour at any one time. Worth a try though I'd say!
seems like you're not using Vin, so you could make your shield smaller by using the 5V and GND from the ICSP header. you'd need some female headers for that though. <br> <br>I like the looks of it. might try a larger glass jar and put the arduino in the middle, maybe with a inductive base for power, how cool would that be!
Thanks for the suggestion! Will give it a try. Would be awesome to see a larger version, a customer made one with glass beads that looked pretty good too.
Marbles? cheap! Neat effect! Good instructable, thanks.
I think marbles would be good, might try and find some for a larger version.
