Introduction: LED Fan/Party Light
Step 1: Parts Needed
This is a very simple project, so there are not many parts needed.
4"x3" Project Board (or smaller, I actually cut mine into three parts about to 1" x 3")
3 volt Button Cell Battery
Button Cell Battery Holder
Mercury Switch (tilt switch)
5mm LEDs (I used Blue, White, RGB, Blue Flashing)
Sticky Tack (blue gummy sticky stuff)
Hack Saw (for cutting Project board)
Step 2: Putting Together the Circuit
Get the Project board to the right size, I cut my 4"x3" board into three pieces, which brought the size of each one closer to 3"x1". Just make sure you take your time while cutting so the copper solder points on the back do not flake off.
Test your circuit. This is very important to do while trying something new. You wouldn't want to solder everything together and find out that it doesn't work, or one of the components were bad. There is a diagram below of the circuit, along with pictures of how I soldered it onto the projeect board.
In this case I did not use any resistors because the LED's that I am using need 3.3 volts, and the power source is 3 volts. Since they are being under powered already, I skipped the resistor. If you add a resistor to these you are going to be under powering them even more. However, some people say that LED's ALWAYS need resistors (which is a good thing to stick by). Your call on this one, party animal.
Step 3: Final Touches
Now that you have the circuit all set up, you are ready to attach them to the fan. I used "Sticky Tack", which a blue sticky clay that allows you to easily attach and easily remove items without leaving any perminant marks. You can attach them however you want, just make sure that you have the mercury switch pointing to the center of the fan so when it turns on the mercury will turn on the lights!
I have tried attaching them to the top of the fan aiming them at the ceiling, and to the bottom aiming them down onto the floor. It really just depends on the mood you want to create.
WARNING: MAKE SURE THE LIGHTS ARE SECURE BEFORE TURNING ON THE FAN. IF THEY ARE NOT, THEY CAN FLY OFF AND CAUSE DAMAGE. I AM NOT RESPONSIBLE FOR ANY DAMAGES CAUSED BY THIS PROJECT. ALSO BE AWARE THAT MERCURY IS POISINOUS-- BE AWARE OF THIS WHEN USING AROUND CHILDREN OR ANIMALS.
BE SAFE AND HAVE FUN!
