Twitter Mood Light - The World's Mood in a Box

Step 2 All you need is...

I ordered most of the electronics from Sparkfun, and picked up the rest from the local Radioshack. The acrylic I got from a local plastic shop(!) - they cut it and drilled a hole free of charge.

Materials

• Arduino Duemilanove
• Wifly Shield www.sparkfun.com/commerce/product_info.php
• Breakaway headers  www.sparkfun.com/commerce/product_info.php
• 9v battery
• 9v to Barrel Jack Adapter
• 5mm RGB LED
• 3x resistors (2x100 ohm,1x180 ohm)
• Wire
• Small printed circuit board
• USB Cable A to B to connect Arduino to computer
• Rosin-core solder
• Source code
  

The Acrylic Box

• 1 x (5" x 5" x 0.25") - the top
• 4 * (4.75" x 4.75" x 0.25") - the 4 walls
• 1 x (4.5" x 4.5" x 0.25") - the base
• 1 x (4.5" x 4.5" x 0.125") - the mirror with a 6mm hole drilled in the middle
• 4 x (4.25 x 1" x 0.25") - the 4 inside walls
• Acrylic solvent cement
• Sand paper (to help diffuse the light)

Tools

• Soldering iron
• A computer
• Arduino development environment
• A wireless network (802.11b/g)
• Pliers
• Wire stripper

Hey ! nice project, very inspiring. btw wanna ask (i'm new with this) is it possible to use ARDUINO ETHERNET SHIELD instead of wifly shield?

will the script be different?

[jmccauley2]

Yes, you could go that route, but you will have to rewrite the sections that reference the WiFly Shield. There's no shortcut, I'm afraid. Change the hardware and you have to change the code.

is alright! i bought the wifly shiled.

Thanks for the reply!

Hi, nice project. I'm being to buy products to do it.

But I think I won't use a 9V battery I'm interrested by a Lithium battery like http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=1&products_id=17 (with a solar panel http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=6&products_id=16 ?).

Let's get crazy :)

Nice!! Where do I get the acrylic plates?

[mdot2theg]

Could I use a a WiMicro for this project instead of a Wifly? And if so would the coding/libraries be much different?
great job btw :)

 Wow! Nice one. This would be a project I would do, if I had the time and a free arudinio. If only there was a way to sync this up with Facebook..
