Introduction: Glowing & Flashing Multicolor Devil Duck

Picture of Glowing & Flashing Multicolor Devil Duck


Here is a little something for People with a beginning understanding with electronics/soldering, that want an easy project that will attract chicks because, well, its a glowing duck! (And it has horns)
Sorry for the crappy pics but my camera is junk. And has no macro function

But here you can see the duck in the light and turned off.
Then you can see the power on and in the dark.

1 a U.V. reactive rubber ducky (I ordered This_one at oznium since it came with a UV LED)

2 Solder Iron/Gun

3 Solder (any size will work)

4 Electrical tape or Heat shrink tubing

5 Wire

6 A switch (I used a toggle but any will work)

7 A battery Holder (optional--can just solder batteries together but once they used up you gotta replace them)-

8 A tri-color/ bi-color /single color LED (I used a tri-color)

Step 1: Connecting and Figuring Everything Out

Since this can be such a varied project I am not going into specific detail about how I made mine.
I am going to tell you how to connect everything and some basics about LEDs and Switches.

If you have no idea what an LED is heres a good instructable for you
LEDs for beginners

And if you have no idea how to wire them go here
How to wire LEDs

These LEDs all run 3.3 volts

These LEDs all run 2.1 Volts

The two LEDs I used were both 3.3 volts so I was able to wire them in a parallel circuit.
Now a diagram if you fall in the same boat as me.....

Step 2: Done Connecting Everything?

Well with the platform I had on mine here is how I had everything connected.

Yours should look similar to mine. (The wiring that is...)

Step 3: Finish

Well for me I wanted more of a spread of light (think a fan --<<) instead of a beam (--->).
in order to do this i put tin foil around areas and i also sanded the top of the LEDs down a bit.

Now I do understand that this was a bit vague but all the info is here.
The rest is up to you.

cough **no current limiting** cough **resister'**'

Why would I need to limit current? I had a 3v source and both LEDs in mine had a forward voltage of 3.3v and they were running in a parallel circuit. And by resistor are you telling me that i need a resistor when the power supply is acftually LESS than the voltage of the LED

I think its still a good idea. The more current you put through a LED the more they tend to draw(the resistance goes down). This leads to a shortened life of the led. It is probably fine though if there is half the voltage of the (on the box) forward voltage across the led, as long as the LED lights.

Nice idea! Please retake with either a better camera or in macro mode, I really want to see what this devilishly smashing project looks like!!

if your going to get this close, use a macro mode. that is the little flower button. blurry pics like this do no justice.

I use the main site:

Which is linked to that site :)

Well, yes and no. is based on the new and improved code. I just didn't have the heart to remove the old ledcalc from Metku. :)

I have way too many Instructables (pictures on my computer) to do, then I have time or energy to do :(
