Multi-Pattern LED Fan, retail $TBA

Last updated 01-23-10

The Multi-Pattern LED Fan (hereinafter probably just called a fan) is a small, handheld battery-operated electric fan. It has three soft plastic blades and a neck lanyard, but most importantly (for this website sakes anyway), there are five tiny LEDs in the hub (the central section of the rotating part that the fan blades are attached to) that create some rather pretty patterns when the fan is used.

There is a circuit of some kind hidden in the fan's head that controls each of the five LEDs individually.

To use the fan, feed it first (see directly below). As the fan is facing you, slide the switch (located on the right-hand side of the fan's body just below the head) upward to turn it on. Slide this switch downward to turn it off.

To change the batteries in this fan, unscrew & remove the small screw on the bottom of the fan's body, and set it aside. Slide the battery door until it lifts slightly, swing it up, remove it, carry it to a bridge over deep water (the Oakland Bay Bridge would be ideal; however, the Juneau-Douglas Bridge would also do in a pinch here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the two used AA cells out of the fan's body and into your hand, and dispose of or recycle them as you see fit.

Insert two new AA cells into the fan's body, orienting them so that the flat-end (-) negative of the leftmost cell (as the fan faces you) faces outward, and the nipple-end (+) positive of the rightmost cell (as the fan faces you) faces outward.

Place the battery hatch back on, insert & then tighten that screw. That takes care of the "fan" portion.

To change the button cells in the fan's head (these cells power the LEDs and driver circuitry), gently pull the fan head off the fan body, and set the fan body aside.

On the inside part of the fan head, you'll see three screws. Unscrew and remove the center screw only, and set it aside. Remove the battery hatch, and set that aside too.

Tip the two used LR44 button cells out of the fan's head and into your hand, and dispose of or recycle them as you see fit.

Insert two new LR44 button cells into the chambers for them, orienting them so that their flat-ends (+) positives face outward.

Place the battery hatch back on, insert & tighten that screw, and gently press the fan head back onto the motor shaft on the fan's body.
Aren't you glad that you didn't throw the battery door from the fan's body over the side of the Juneau-Douglas Bridge now?

This is what the Juneau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.

And this is what the bridge looks like now.

This is a portable electric fan, not a flashlight designed to be thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a patio, use a small sledgehammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

This fan is not very water-resistant; and isn't waterproof submersible at all. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of African lion pee, slush piles, mud puddles, tubs, toliet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found. You can use it in a very light sprinkle, but any heavier than that and you'll want to stash it away.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your fan to smell like seaweed or uranation when you go to use it next. Besides, salt (from seawater or piddle) can't be very good for the motor, the LED driver circuitry, or the battery contacts.

The LEDs in the fan hub produce beautiful patterns of light that must really be seen to be appreciated. The movie I provide farther down this web page really doesn't do the fan justice, but it's better than nothing at all.

The fan blades are made of very soft plastic, so you will not cut your finger on them if you poke at the blades when the fan is operating.

Test unit was obtained in 2003 or possibly 2004; it was probably something I picked up on Ebay for a couple of bucks. It was found on the evening of 01-21-10 while I was looking for other LED fans that required spectroscopy.

Product was almost certainly made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.
