Introduction: Pro LED Fan Mod

About: i enjoy inventing, taking apart electronics, and rebuilding them. i also have a hobby of creating batch files, i greatly enjoy programming batch. i also enjoy coding and decoding binary code.

In this instructable i will show how to make the LED fan with reed switches and magnets.

Step 1: Step 1: What You Need

You will need:
A fan
Reed switches
Switch
9 volt battery and holder
wire
LED strips
Magnets
Tools:
Soldering iron and solder
Hot glue gun and glue

Step 2: Step 2: Getting the LED Strips.

Buy one of those umbrella lights from the dollar store, take it apart and desolder the connecting leads and you will have 4 strips of 8 LED's. YAY! Super cheap!

Step 3: Step 3: How to Get She Seed Switches

Buy a window alarm and open the case, find the skinny glass tube, desaolder it and you have it, do this twice, or for however many LED strips you use.

Step 4: Step 4: Start

Start by cleaning and removing the grate from the fan. Then prepare the LED strips and 4 wires by stripping 1 cm from each end. Then solder wires to the positive and negative of each LED strip. Also solder a wire to each end of the 2 ( or more ) reed switches. Have all the wires as long as a fan blade for both.

Step 5: Step 5: Solder and Glue

Now glue the LED strips to the fan blades, and the reed switches to either a clear blade ( what i did ) or further apart. then solder one wire from the reed switch to one from the LED strips. Do this to each, and make sure they are the same polarity ( + / - ). Now take the other 2 wires From the LED strips and solder tham together, do the same with the 2 from the reed switches. Then take the wires from the reed switches and solder them to the positive from the 9 volt battery clip. Solder a switch to the negative, and hook that up to the LED strip wires. Clip on the battery and glue it to the center of the fan. Then glue all of the loose wires into place.

Step 6: Step 6: Magnets

I'm sure that you do, but if you didn't, reed switches work on the rinciple of 2 small metal tabs being held together by a magnet, so we need some. Take some magnets, you need strond ones, and glue them to the inside of the fan grate. Thats pretty much it.

Step 7: Step 7: Done

Now place the gratew back on the pan, and your done! Here are some pics of the fan.

Step 8: Movie

Here are 2 movies of the fan.

Step 9: Caution!

Dont let your friends poke their finger into the wires while it is runing. I left mine alone too long and he wrecked it. Now i need a new switch and some more wires.

Step 10: Final Note.

    Great Idea and love it... the only problem is you cant shut it unless you remove the magnets or the battery. You may be able to fix this by adjusting the switch so the centrifugal force will push the two contacts together.

    i turn old fans into low poer centrifuges nice ible 5 stars

    thx! I sometimes turn of fans in centrifuges as well, and spin bugs around in them LOL

    i once got some bees in a mini jar and took them to this paint mixing machine in b and q and shook them up and let them go lol

    LQTM Nice! Were they dizzy?

    no idea they were hiper though lol

    This is a cool project. Where did you get the idea for this? How is the vibration of the fan now that the blades are not totally in balance?

    1 reply

    well, i got the idea from 2 things. one, ive seen mini fans that display text/ patterns, and 2, i noticed that when you swing a glow-stick that it makes a circle of light, because our eyes dont pick it up fast enough, so i figured that this would work. there is virtually no vibration that i can see, let alone making the fan shake. i believe the 9 volt battery may help because it adds weight in the middle.

    i am definetly going to try this!!!!!!!!!!!!!!! ggoooooodd idea!!!!!!!!!!!

    thx. Two thing you can/should do. If I had the time/money I would have exchanged some of the LEDs for colored ones, and I would also put th ereed switches on seperate blades for more flashing. Let me know how it works out!

    Now that is pretty tight man. I might try light effects with my fan win I get home.
