on first seeing the various laser vortex's my first thought was those are so cool i've always wanted one. On realizing how easily the effect is created I realized how cheap it would be to finally own one of my very own. if you think it's cool too building this version the omni vortex could not be cheaper or easier:

Materials:

1 fog machine if you dont have this you might wanna stop right here.

1 oust fan look for supermarket promotions to save more off the suggested retail or try ebay.

1 laser pointer I got mine at my local five below seems to be here as well.

1 small mirror mine is a perfect little 2 inch mirror from joann fabrics

exacto (hobby, boxcutter or other)knife

glue (I used hotglue)

optional: (soldering iron, solder, and a 4 inch piece of wire)

if you paid full retail for everything new including the tools it would probably cost about...

$20.00 fog machene
$8.00 oust fan
$4.00 laser pointer
$ .99 small mirror
$2.99 knife
$3.99 hot glue gun with glue
$7.99 soldering iron
$0.99 solder
$0.99 wire
____________
$49.94
if this is the case save yourself the hassle and go buy yourself a fog machine and one of these otherwise pick up what you don't already have lying around(for me it was $6 worth) and we'll start.

Construction:



1.open up your oust fan package open your battery compartment remove the battery if one is there. grab your knife and cut off the fan guard to reveal the fan blades.

2. heat up your hot glue and pull one of the mirrors out of the package.

3. drip a as big a glob of glue onto just the center of the fan being careful not to hinder the movement of the fan blades and immediately stick the back of the mirror on the glue keeping the mirror at a slight tilt mine is flat against one edge and the opposite side of the mirror is raised about 1/4 inch.hold the mirror there till the glue dries ushally about a minute for hot glue.



4.if your laser pointer has a handy bendable arm like mine hot glue it to the top of the fan.

optional:
The oust fan by default runs for five minutes then stops for 15 then runs for five and so on when the fan stops your tunnel will turn into a line and when it starts again will turn back into a tunnel if this schedule is good for you then theres no need to follow these instructions if like me you want your tunnel to always be a tunnel heres a quick fix:

5. cut open the back of the oust fan to reveal the back of the motor.

6. solder your wire to the lead on the left



7. open your battery compartment remove the battery if one is there and pass the other end of the wire you just soldered down into the battery compartment.

8.solder the other end onto the solder point shown below



from now on when you insert the battery the fan will start to stop it simply remove the battery again.

finally:

all thats left now is to fire up your fog machene get a good fog going and aim your laser pointer at the mirror. the vortex will work in minimal light but the darker the better.



success! now show off your omni vortex of doom!!!muahahahaha!
