Geeky Gadgets for Halloween Parties?

Neurotoxic666 asks: "Like many others, my friends and I are going to hold a costumed party for Halloween, however we do not want it to be the typical haunt. We have some talent in computers and electronics, but we're short of ideas. Are there any good gadgets and props that the average geek can build to spice up the party? Of course, there will be the usual ambient sounds and decoration, but we're looking for more interactive, dynamic and techie stuff. One idea I've had is to use the living room computer on the TV and have white noise, ghosts and other creepy effects appear throughout the night. Does anyone have some suggestions, ideas we could build, effects that worked well in your parties? Anything from heart-beating books to special lightning to mad science devices is welcome!"

      Something I did at a convention while running a Tron-themed room was to create some glowy drink. The magic ingredient is Tonic Water, but you have to mask the horrible, horrible aftertaste.

      My solution was this:

          Blue Raspberry Kool-Aid, unsweetened - 1 packet
          Tonic Water - 1 cup
          Water - 7 cups
          Sugar - 2 cups

          Prepare the Kool-Aid per normal, only with the above-listed ingredients. Blue Kool-Aid tends to look pretty bright on its own, but it glows fantastically under blacklight with the tonic water added in. 2 cups might seem like a lot of sugar, but it's absolutely necessary to cover the taste of the quinine.
          Cherry or Orange Kool-Aid might work well for something more "spooky" on Halloween, but I'd recommend testing it in advance to make sure that it gets as good of a glow as you'd like. Avoid anything lemonade-y, as the sharp citrus only brings out the flavor of the quinine, which you really, really want to avoid.
          If it's just adults that'll be drinking it, you can cut the sugar a touch (maybe down to 1.5 cups), increase the proportion of Tonic Water a bit (maybe up to 1.5 cups - 2 cups tops) and add vodka to taste. Add more vodka if you increased the Tonic Water too much - again, to help mask the quinine.
          Also, a word on blacklights: those 25W "blacklight" bulbs you get at your local general store are crap. Go to Spencer's or your local equivalent and pick up a flourescent blacklight. They even have blacklight CF's you can drop into existing light fixtures - waaaay more blacklight and so much less of that "I'm really purple, but trying hard to be UV".

(Where "very scary" literally means anything that would bother a mentally hadicapped five year old...)

      So, I decided it would be fun to write a "performance animation" program. Basically, there will be a 3D pumpkin character projected on one of the walls. He will have a background that appears perspective-correct to a person standing in the right spot, thanks to a two-pass rendering algorithm. The character will have a set of triggerable animations and gestures for his hands, and several facial morphs so that he can appear to talk. I will be in another room controlling the animation of the pumpkin king over VNC, and doing the voice, while I watch the kids on a hidden web cam in the room.

      It should be pretty slick as soon as I get afew more things finished. It parses and displays the hand animation just fine - still need to add image loading, get texture coordinates from the object files, and add a bit of extra glue for my facial morphing code.

I'm also looking for new things to do, fun ways to use that dusty webcam, cool computer-assisted games, totally geeky special effects with a simple LEDs-and-AA-battery setup, DIY motion detectors, sound effects for that logitech sub-woofer, sounds activated by something, toys to interact with, everyday mechanisms that can be reused to animate some prop, etc... Like creating a Flash-based fortune-teller, having a brain-in-a-jar speak by itself using an mp3 player,...

      Also, if I may, here are some rather dark music suggestions for your own party, if you're looking for a better soundtrack than the average Halloween CD. Check out these bands: Am'ganesha'n, Arcana, Fantomas, Apocalyptica, Empyrium, Elend, Diamanda Galas and Boards of Canada. I know most of them can be found in MP3's somewhere (*cough*bittorrent*cough*). And of course, there's Mozarts' Requiem and Carmina Burana. And you'll find plenty of sound effects here.

On my porch this year, I'm making a bigger version of an effect that was really popular in previous years.

I then looped that onto a DVD for an hours worth of one large eye. I got a big screen teevee front screen from a nearby teevee shop, off a dead teevee, you might have to seek out a teevee shop to get one, and am going to project it so that I'll have a 4 foot wide eye gawking at people.

      Basically, it's very simple. Set up your scene with accurate scale, and out the camera where the kid will be. Have your "extended scene" with whatever. Render.

      Then, on the second pass, you put the camera where the projector will be, and use projective texture mapping, so that there is basically a 'spotlight' projecting the previously rendered image onto the walls/screen. This time, the extended scene is not directly visible - the wall you will be making disappear" is what you project the texture onto. I'm going to use a simple vertex for this.

      I'm sure it's possible to make a single-pass technique with wicked matrix math, but I'm not that adventurous with only a week left. I think if you did a single pass technique, you would have to restrict yourself to only projecting onto one flat wall. The two pass method will allow fairly arbitrary geometry, as long as every point can be seen by both the viewer and the projector.

The image bounces off the mirror and hits the back of the box and the smoke gives an interesting halo effect to the whole image.
    Edit a video file to include random static and ghostly images and burn to DVD or stream from your computer- pretend like it's just a regular movie (The original Night of the Living Dead is available as public domain from Archive.org if you don't want to worry about copyright infringement and was a good scary movie). This can work even better if you record a movie off the TV with commercials and all so that it may be less obvious what you are doing.
    Set the Air Conditioner on a timer so certain rooms can develop "cold spots".
    A lot of digital video camers will pick up Infra Red light from things like TV remotes- this is a good way to create fake "orbs" in photos or videos to spook out your guests.
    A good, edible fake blood can be made with corn syrup, corn starch (to thicken it and make it less transparent) and red food coloring.
    A few more general notes, remember that things are often a lot more freaksom if there is less of a setup, include some really hokey and poorly done tricks to put your guests at ease, this can make the good stuff more effective. Also remember that panick spreads- so make sure to act freaked out and assure your guests that you had nothing to do with your tricks- this can make the entire thing much more effective. Also try to make sure that things are less predictable, if a spooky noise sounds off every time someone walks down a hallway it can ruin the illusion.
    Try to get a couple of other people "in" on the setup before hand- that way you have a pool of people who can set things up so that your guests don't learn to expect something every time you excuse yourself to the kitchen or bathroom.
    Above all, keep in mind that the scariest things are generally unseen or heavily veiled, props that are too goesh (grammar nazis, I tried to find the correct spelling of this word to no avail, anyone care to help?) often turn out to be humerous instead of scary.

      To an extent, I have to agree. In my experiences over the many years, I've concluded that other than being ten years old and wanting a sugar fix, halloween is mostly for women. They like to get dressed up, play pretend and get a lot of attention. Especially if they can wear things that they otherwise might not get to. And they're largely the same selected handful of cliches. Most guys have seemed not to care too much. They go along either in the hopes of seeing and/or scoring with hot easy chicks after they've had a few too many or to watch that their own girlfriend (who probably dragged him along) didn't turn into one of the tipsy spread-eageled ho-bags craving the spotlight.

      I know it sounds like the spoutings of an anti-social geezer, but I've just been to one too many of these things and seen too many bored guys and trampy attention whores in my years at them. Maybe it's different if you're talking about a small group of friends gathering for a few drinks and dinner in your living room, but any public event or major party will inevitably turn into something a shade or three off of what I described.

      Anyway, I got over the dressing up and playing pretend thing a long time ago and I'm not so desparately craving attention that the few "oh that's a cool costume" comments are going to be worth my energy. I'll probably spend Halloween at home, resting from the hard week at the office (my week stops at midnight, Sundays) - or out crusing in my new 2006 Mustang.

(It needs to be almost, but not perfectly, perpendicular to the shaft.) Glue a small mirror (1" square or less) onto the penny. Turn on the motor and bounce the beam off the spinning mirror. Add some fog to the room and dim the lights, and you've got a very cool effect indeed. (Wrap a rubber band around the barrel of the laser pointer to keep it on, and tape it into position near the spinning mirror.)

    Or you can build two spinning mirror assemblies and generate lissajous patterns. (Think: Spirograph)

    Or use some hot glue to tack a tiny mirror onto your speaker's woofer. Bounce the laser off the mirror while you play loud music, and you'll get all sorts of wierd patterns.

  92. The heart attack mirror (one of my favorites) by Anonymous Coward · · Score: 0

    Who can't resist checking out their own costume when there's a mirror near by? This creates the best setup situation to scare (at the very LEAST severly startle) our un-suspecting victim. My friends, make a mirror, but not just any mirror... a TWO way mirror! This one makes me laugh just thinking about it from the past years...

    Materials:
    Some wood to make a good size frame
    Some "mirrored mylar" or silvery window tint (enough to cover your frame)
    Some thing somewhat scary in general, like a good MASK, or a stuffed dummy
    A light source... 100 watt red or green flood lamp?
    10' X 25' roll of black plastic ($7 at home depot)

    Build a rectangular frame with the wood and some wood screws. 1 X 3 makes a nice solid frame, but if you like 2 X 4's... fine... Stretch and staple the mirrored mylar or silvery window tint around the wooden frame so it is tight enough to create a smooth reflective surface. If you want to go the extra mile, you can put some molding or decorations around the edge of the "mirror" to give it a finished look. Finally, create a small, dark, enclosed area/room BEHIND the mirror from the sheet plastic... an area big enough for a person to stand behind the mirror. It must be completely dark in this area behind the mirror.

    How it works:
    Place the structure in a relatively dim area with JUST enough light so the unsuspecting victing can walk over and check out his or her costume / mask / bloody scars / etc... What this person doesn't know is that you (or your consort) is on the other side of the mirror hiding (trying not to laugh) in the dark plastic room, as the lack of light in the "dark room" does not allow them to see through the mylar.

    Just as the victim moves in REAL CLOSE to the mirror to check out that bloody scab that took them 20 minutes to get JUST RIGHT, you, on the other side of the mirror move in JUST AS CLOSE, so you're virtually FACE to FACE, with only a paper-thin piece of mylar between you.

    It is about this time you would want to apply power to the green flood light located near your belly, pointed up at your chin. When the light comes on, the mylar virtually becomes transparent and disappears, allowing the victim to see a hideous ghoul 2 inches from their face.

    The reactions are priceless.

  93. Non-lame idea by Anonymous Coward · · Score: 0

    Halloween should mean something. It shouldn't be "Hey let's get drunk amid tired old props that we all know are fake yet find mildly amusing in an ironic way." Halloween should invoke fear, absolute OMFG SMP terror.

    First, you need to eliminate all the ideas that people have had before, and all the things that are illegal or could actually result in hurting people. If there are mentally unstable people, they should not be invited to your party or haunted house.

    You have to know what fear is, essentially. Fear is of the unknown. To create an unknown situation, you bring people to a location where they haven't been before. You take away at least one of their senses. For example, you take away sight by making it pitch black or foggy or their hearing by filling the room with noise.

    You look to science fiction and paranormal crap for what is cutting edge. Right now that is EVP, electronic voice phenomena. This is big with Art Bell. They listen to voices that are carried inside electric cables. It is believed (whatever) that old, dead souls left an imprint, perhaps their souls on this.

    You tell your unwary "guests" about this, make it sound real, and tell them you've discovered an EVP inside that you want to share with them. You lead them into a foggy, lit room and start trying to "talk to" or "hear" the voices you heard on the electronic wires. Nothing happens. You tell your guests you're going to give it some extra amps to see if it will "wake it up. Don't worry. It will be okay." You pretend to jolt it out. Then you trigger an electric spark effect so it looks like you are electrocuted. You fall over and "die."

    The lights go off, leaving everyone in a pitch black room. Then you crank up the staticky EVP you prerecorded. Something about aborted babies and hooks and snakes and how the guy was murdered years ago and is all pissed now and there is Satan too and it is going to kill everyone and other shit you can think of. At this point you spray everyone with fake blood from a remote-controlled spigot soit splatters everywhere. Then there's a strobe light effect so they can see each other splattered in blood. After a few seconds, you are back to pitch black and silence for a few seconds.

    Then you invoke the primitive fear we all have of fire. On cue, a torch just lights up on the other side of the room a strawman you purposefully constructed in a metal and glass case, with the smoke piped outside. Then they run, but the EVP starts up again and they encounter one of the hosts lying there who is dimly lit and splattered with gore and stuck with a fake knife. Four or five slimed up rubber snakes drop on their heads. At this point they all need a change.

    That is a haunted house.

    1) The first guests to arrive, make sure there's about two of them or so. Leave the door open and all the lights off inside. Upon entering, someone who was hiding near/behind/around the door (on the outside of the house) slams it shut and holds it there. In the opening room:

    a) Paint things like 'HELP ME' or things in latin in big, red, sketchy letters on your wall, or something similar that you can remove easily. When the lights are turned on, this will help to create the effect for our big finale.

    ---OR---

    b) Disconnect the light switches so they can't be turned on since you chose not to paint on your walls.

    --THEN--

    c) Leave some sort of marker leading them into a hallway that leads to one room (the rest are locked) with (optionally) the the big red letters from above spelling "HELL AWAITS".

    2) Then once they enter the room, yet another person hiding (maybe in a pantry locked from the inside using two pegs and a stick or something) will slam that door shut, locking it and holding it shut.

    This is where the REAL fun starts.

    In that room you'll have a TV. Using the infrared motion detector mentioned earlier, have a TV and a VCR hooked up to the detector. Make sure the VCR is cued to the tape I'll mention in a second. When they enter the room and the door has locked behind them, the VCR will begin playing our tape we will create later. The first bits of the tape will need to be white noise, about 15 seconds of it, before snapping into a video of strange things in black and white. Not necissarily scary by themselves, but downright AWFUL in a house decorated like that with the events that have happened up to that point (think the tape from The Ring).

    After the section of the tape has stopped, the remainder of our white noise will continue (lets say... five minutes of it). Someone in the closet of that room, dressed as some awful humanoid monster (like the pyramid head guy from Silent Hill 2) will calmly walk out carrying a blunt long object like a pole, but enough so that if you were to hit someone with it in the stomach, say, it wouldnt hurt too much.

    This is where a friend of the group comes into play. He'll have some sort of blood-packet on his chest, on top of a vest preferably so the strike to his chest/stomach doesn't hurt so much. The monster person will stand facing the visitors, and after a few seconds snap into action and hit the friend in the stomach with the spear, we'll call it, causing fake 'blood' to erupt from his chest section.

    Proceed to go after the remaining people, who should now be THOROUGHLY scared. Maybe leave a chainsaw in the closet for after the first 'killing'.

    A couple years ago I built a fog machine based on plans I found somewhere on the web. It was very simple to make and cost under $10. I've always meant to put up my own web page showing how to do it, but you know how that goes. It's not that hard though, especially if you are a true geek. Basically you get a used electric iron and mount it upside down in a shoebox-size box, with a drip mechanism that drips a glycerine and water solution onto the iron, and a computer fan at one end blowing in. Needless to say, you wire the fan and iron to a switch.

    For me the hardest part was making the drip mechanism and getting the drip rate right. You want a drip rate of several drops per second but not a running stream. I bought a used aquarium pump but it ran WAY too fast. So I ended up using gravity. I mounted a 2-liter pop bottle upside down on top of the box, with a piece of plastic tubing epoxied through a hole in the cap, extending down into the box. I fused the end of the tubing shut with a candle flame and poked several pinholes in it until it flowed right. Initially the thing stopped dripping after just a few seconds, so I had to poke a hole in the pop bottle's bottom end (which was at the top) to allow air to enter. Then the drip rate was too fast, so I heat-sealed some of the holes in the tubing. It was trial and error, and it ran a little too fast when the bottle was full and too slow when it was low on juice. Some sort of slow pump would work better. But what the hell, the parts were free.

    The drops of glycerine instantly boil away to dense white fog when they hit the hot iron, and the fan blows the fog out the other end of the box. Commercial fog juice is a 25% solution of glycerine in water. A 12-oz bottle of glycerine costs about $8 at the drug store. Mix it with 3 parts water and you're there. This quantity will last a couple hours.

    The fog machine emits steam, which rises. To make the fog float along the ground you need a chiller, which you can build with an old styrofoam cooler. Cut a 3-inch hole cut in each end, with a tunnel of wire mesh connecting the two holes. You fill the cooler with ice and put the fog machine up against the hole at one end. When the hot fog passes through the chilled tunnel it will stay close to the ground. You don't actually need pieces of plastic pipe or anything, unless you want to duct the fog somewhere.

    Instead of using my fog machine to fog up the living room I made a cemetery in the front yard. I had various slabs of styrofoam lying around from who knows what, in thicknesses ranging from 1/2" to 2". If you don't have any just get a 2x8 sheet of rigid foam insulation an inch or two thick. I cut out tombstone shapes with a scroll saw, and for good measure cut a few cracks and other defects into the edges with a serrated kitchen knife. Then I used a soldering iron with a large tip to carve out lettering on each one. The foam melts away at the touch of the iron, and the result has a nice deteriorated look. Then I spray painted the tombstones gray and then sprayed lightly over with black in a haphazard pattern to distress them.

    I mounted the stones in the yard using a coat hanger stuck in the bottom of each one and into the ground. Lighting fog from the side looks really good, so I hung a lawn spotlight in a large bush about 15 ft away, downwind of the graveyard, shining through the leaves at the tombstones. The tombstones themselves were standing at an angle to accentuate the shadowing inside the carved letters. It made the lettering really visible. On the upwind side I set up the fog machine and aimed it toward the sidewalk. As the fog came out the slight breeze blew it gently across the yard, through the graveyard and toward the light. My wife hung small stereo speakers in the same bush as the spotlight and we had creepy organ music playing. All in all it was a really cool effect.

  140. One Fun Party Idea and then some by Geeko+Roman · · Score: 1

    I'm too tired tonight to really get into this (1am) but maybe tomorrow. I do Halloween stuff professionally, with serious theme park gear. Checkout http://www.rivertoncemetery.com./

    One fun party idea if this matches with your theming, is to stack a bunch of TVs in a pile. The older the better, different sizes. It's best if they're all black and white, but it doesn't matter. Stack some sideways, some upside down. Plug them all in, turn them all on, so that they're all playing static. Then I like to take one or two odd random ones (at least turned the correct way) and wire them to the same DVD or VCR, and playback wihtout audio (I assume you have loud tunes at this party) old black and white movies. Some good choices are Frankenstein, Mummy, The Fly, Them, Dracula, Nosferatu (my fav), or something like this. Also Metropolis is ok.

    If you can afford to jack up the TVs, paint them jet black (except the screen) with some silver paint dripped down the side of some. Gives it a retro techno post-apocalypse big-brother feel.

    Another idea is to run a fine copper wire around each half of the seat of the toilet in the bathroom, and run each side to a terminal of a transformer, and hook that transformer to a 9V battery. When the person is using the toilet, you connect the battery (or push a button) and it momentarily sends a jolt to the person's bare a*s. DISCLAIMER - this can injure people if they are sensitive to elecricity because it F's with your heart, or if the current is too strong. Use with extreme caution and at your own risk, and make sure you use a low enough transformer.

    On using fog - if you can make an elongated wooden box with a fan at one end, and put regular ice in a bowl in the box, then hook up a dryer hose to each end of the box, and run your fog machine into one end, this will "chill" the fog to keep it lying low in the house. Otherwise you need a Liquid Nitrogen rig to put out fog that's denser than air and will sink to the floor like dry ice.

    Make a giant skull facade over your front door so that people walk through the mouth to enter.

    Have a friend sit a styrofoam stylist's head with a scary mask draped over it on his head. Have him put on a big athletic sweatshirt over his head so the hood of the sweatshirt is around the fake head. His actual head is below where the zipper is. Have him stand against the wall with his hands hidden on the wall where people walk by to get to the front door. Have him practice acting like a dummy and standing funny (proped) against the wall. You can add other imbellishments to make it look like a dummy. When people walk by, they think he's a fake dummy, and he can jump at them and scare them. This works will little to no effort (get a mask), but requires a patient and well-propped up guy who practices.

    Do NOT use candles outdoors for any reason. Use them indoors only if there is someone to supervise who is sober. I do not recommend them despite their good looks. One note - you can buy broken candles by the pound (cheap) if you ask around (I forget in my old age).

    You can make tombstones out of styrofoam covered in plaster of paris (get at Home Depot for cheap, not hobby store). Take pictures of gravestones from old cemeteries or find off of the Net. Do a good job or don't bother.

    You can paint light bulbs red, blue, or green, if you don't want to buy the ready made ones at Home Depot. Use High-Temp paint, and test them before using them.

    A fun twist at parties is to look up All Hallows Eve or All Saints Day/All Souls Day. Halloween is a traditional Druids Thanksgiving before it was a Christian holiday (what you may find may shock you in the truth of it all). You can also use info from an Irish or British All Hallowees Eve. Tell fortunes by the fire by roasting walnuts. Use a snapapple (Halloween also called SnapApple night). Serve Irish soul-cakes to the guests (they're pretty good to eat and very cool in theme IMHO). Some years I

Have them display static, random flickering colors, maybe a few wireframe 3D objects (for that 1980ish feeling). xscreensaver has some modes that are just perfect, for example some of BSOD's modes. Repeatedly compiling something that generates lots of text output might also be a good idea - having three or four monitors next to each other, each one scrolling through lots of technical-looking text (dmesg via Phosphor is great for this) should create a nice effect. Even nicer if you configure your terminal to use #00ff00 green text. Hang lots of tubes, wires etc. from the ceiling, making it look like everything was wired together in a haphazard way. Some loose cables dangling around (but obviously not connected to anything) add to the effect. The light comes from fluorescent lamps hanging between the wires.

    That should create a nice cyberpunkish effect for everyone who loves the genre.

  160. Be careful about fog machines by maggard · · Score: 2, Informative
    Not to be a killjoy, but overheating glycerin can potentially create toxic fumes - probably more gruesome then you want your party to end up...

    A pre-built fog machine costs about US$20 at most larger stores and is temperature regulated so you don't poison anyone, making it a wiser investment then strapping your clothes iron, a drip mechanism, and a small fan together (quieter and easier to work with too!). Also keep in mind the fine glycerin smoke can trigger asthmatics & other folks with breathing problems, and leaves a thin greasy layer on EVERYTHING if used indoors (walls, ceilings, windows, dishware, flooring, into cabinets & rooms you thought were better sealed...)

    While on the not-a-good-ideas theme don't go adding scents, colorings, or other "effects" to the fog. After being scalded on the hot plate and then blown around they never do more then smell nasty, gum up the works, and again, are potentially hazardous to inhale.

    From a fella who spent a half hour prepping his for machines this afternoon my advice is outside, in a sheltered area (wind destroys it), and spooky but not pea-soup. The cooler trick is a good one, and a great use of an end-of-season beat up cheapy foam cooler. A chicken-wire tube between two holes, a load of ice, no fan needed, warm rising fog goes jetting in one end and comes out nearly as fast but spookier ground-hugging fog at the other end. You can even use a short bit of dryer hose if you need to 'pipe' the fog. Oh, and a black cloth hides the cooler, but leave the fogger exposed as they get very hot and need to be refilled occ. My favorite places are hemmed in by shrubs, which I hang some more black cloth around the bottoms to help dam in the ground fog. A bit of lighting helps to show up the fog, nothing like a red or purple glow fromn down low to add yet more atmosphere...

    Sound also helps immeasurably! I use my collection of old came-with-it computer speakers, hidden up in trees and in shrubs, for effects. I plug them into old tape & CD players, then every hour do a circuit around the property restarting 'em. Mix your own audio, and don't be afraid of long periods of quiet rustling, or even silence, punctuated by loud effects. A surprise sound is scarier then walking up to a cacophony of moaning / creaking / screaming. Never underestimate the terror of a real person either; stationing an accomplice in a closet or bushes to make appropriate sounds is incredibly effective, just make sure they're up for a longish stint at it.

    For other effects one of my preferred is the good old black light. You have to be careful however, many of the little purple holiday lights labeled "black light" don't actually emit any UV! Test anything you buy ASAP and bring it back for a refund if nothing glows. The best values are the medium tube lights, around US$15 for a 24" one with fixture. Or get a bunch of the incandescent bulbs for US$1 each and gang them up, stick in corners, behind props, use aluminum foil reflectors to direct their light.

    For making stuff glow under black light the classic is any laundry whitener, "Whisk" is one of my favorites. Paint with it, rinse cloth in it, it's a powerful UV reflector (why your clothes look so bright when washed with it!) Many toothpastes are also dosed with strong UV reflectors, for that blinding-white-in-the-mirror effect (that dissipates down your throat within a few minutes).

    However my personal favorite is black light hair spray. Found in many party supply shops this time of year it costs around US$2/can and goes on nearly transparent, perfect for applying stencils to surfaces (including windows & mirrors!), clothing, or body parts. Right now I've got garage windows full of cheap black & white 'haunted face' plastic masks sprayed with the stuff ready for the room-of-doom next week. Cost was a US$1 75 watt black light, 6 US$1 masks, and that US$2 can of hair spray. Same for my own hair and outfit this weekend out at adult parties, normal until the black lights go on then covered in

    Essentially, the software monitors 5 switches fed into the parallel port. When the state of one of those switches is set, the software respons by firing any of 8 relays tied to the parallel port. Scripting is supported.

    In our current setup, I use a weird setup of old PC's, relay cards, input boards, etc, to switch 110VAC, 12VDC, and 24VAC. We tie these lines to our air valves, lights, and whatnot. The software can also play audio files, so it is pretty trivial to create Thunder and Lighting effects.

    And, along the effect lines, check out the super-easy to make light flicker circuit. Go fetch a standard extension cord, cut one of the sides (as if you were going to install a switch), and install a 4 watt flourscent lamp starter. Plug a low-wattage lamp into the cord, and the cord into the wall. You will get a nice flicker effect.

    Things to note:

    • Be careful and keep an eye on it. I've had these things melt, and you don't want to burn down your house.
    • Use low-wattage starters. The smaller the better. Seems like anything over 10 won't work.
