Do you know someone who wants to learn a bit about electronics? Wiring up some components is the first step in starting the journey. Or maybe you just want to try out some of these cool Flashing RGB LEDs! With a total project cost of between $2.00 and $3.00 the time is right to try some of these things out. They can add some fun to the holidays that are just around the corner, these RGB LEDs will be on sale for the next while so that you can get some to spruce up the holiday season. :)

You can see the original article format here at Hacked Gadgets.

Step 1: Gather the Parts and Tools

The parts needed are:

1 X 9 Volt Battery Snap
1 X Flashing RGB LED
1 X 470 ohm Resistor (not required at the moment since a compatible resistor is included with the purchase of the LED)
1X LED Mounting Board
1 X 6mm Heat shrink

Tools Needed:

Soldering Iron & Solder
Hot Air Gun
Side Cutters

Would this be possible with one of the 3v watch batteries that some of the othe led projects use? 
You could do it with a few coin cells but not one since the LED voltage is slightly greater than the 3 volt coin cell.<br />
Hi,can you connect in the same circuit these rgb leds with some normal ones,without making the normal ones flash?I mean with the same power source,one flashing rgb and one solid one?&nbsp;
I think they should be okay except you may see some slight intensity changes in the normal LEDs as the current changes in the flashing ones.<br />
I have tried this way and yes, there is a change in intensity as you are saying.That is what I was trying to avoid because it is not slight,it is almost as the solid one flashes also. I guess you should use some kind of circuit but not sure what...&nbsp;
You can connect them in parallel to the existing LED power supply. That way this flashing LED will be independent of the others.<br /> http://www.allaboutcircuits.com/vol_1/chpt_5/1.html<br />
could really just omit the board altogether for this ;)<br />
You sure could, but it makes it real nice to solder everything together with. It is also great for someone who wants to learn how to solder a PCB. Although it is a bit harder than a regular one because they are very small.<br /> http://alan-parekh.vstore.ca/product_info.php/cPath/10/products_id/71<br /> <br />
