LET THERE BE LIGHT(ning)!

Difficulty Rating:

This tutorial is here to give you a basic walkthrough of building a one-channel color organ (audio to light modulator) which you'll use  to power a home haunt lightning effect. 

First off, order yourself a kit. Garage of Evil recommends the "K12 audio to light modulator" (Here's where we got ours...). Easy as pie to build, and very reliable (at least until I just jinxed myself). If you're unsure where to order from, just google that exact description and you'll find plenty of online resources. 

Once you get it, it will look nothing like this:

color organ, kit12

It will be a bunch of pieces in a bag.  

That's where you come in.  

Don't think I posted that completed kit to belittle you. If you're an electronics doofus like me, here's a secret - that picture is all you need to assemble this. Print it out and save it for when you start. 

Should you read the instructions? Of course. They include a lot of verbiage like, "Mains voltage can kill you"... Pay careful attention to that advice, as it's very hard to complete this kit dead. Hear me loud and clear on this: 

THERE IS NOTHING MORE PATHETIC THAN HAUNTING A $12 ELECTRONICS KIT FOR ALL ETERNITY. 

With that said, lets move on... 

Time to motor off to you local Radio Shanty and pick up the following basics: 

  • Soldering Iron - get a pencil iron as some of the pieces are a tight squeeze. (RS # 64-2071)
  • De-Soldering tool - trust me, you'll drop a solder blob in the wrong place. This will save tremendous frustration. (RS # 64-2098)
  • Solder - Rosin Core. (RS Part # 64-008)
  • Optional - Little handy helper alligator grip hold the piece thingie. These things are actually pretty handy. (RS # 64-2991)

Then head over to a hardware store and pick up: 

  • (2) 100W - or whatever is closest to that - Floodlights. Make sure the wattage of both lights is under 220W. No more than 110W poor lights (damn I'm smaht!).
  • (1) Sacrificial extension cord, any length will do.

Alrighty then, lets start: 

  1. Read the instructions front to back. They're one page long, get over it.
  2. Per instructions, pick out the correct resistor for you 110V. Not sure which one, use the resistor color code guide on our FAQ page.
  3. Lay out all the pieces.
  4. Plug in Iron, and once heated run some solder into the tip to "tin"¯ it.
  5. Get a beer. If the ballgame is on, root for the Red Sox. If you're a Yankees fan, stick the Iron up your @%&.
  6. Using the picture as reference, start with the lowest (height off the board) parts first and commence soldering. Do not insert the IC into its base until your're done, and solder the Triac last, per instructions. Be careful, pay attention to the solder joints so they don't "bleed"¯ into one another, thus shorting anything. If you make a connection too sloppy, use the solder sucker to clean it and try again.
  7. Get fancy and throw the whole thing into a project box (RS # 270-1807) and use stand-offs ( RS # 276-1381 )to keep the board off the box. Drill holes where applicable, and get a 1/8"¯ mono to whatever flavor input source you have.
 

Hook it up like so (Load side is lights):

The easiest way to do this is to sacrifice an extension cord. Cut it in half, wire the plug end to the power side, and the receptacle end to the load side. Now all you need to do is plug your lights into the receptacle and voila. Done. 

  1. Now take the left speaker output from your sound source and plug that into the 1/8"¯ mono input on the kit. Run the right speaker output to a speaker.
  2. Insert "Jungle Boogie"¯by Kool and the Gang (or, use Steve-O's Color Organ mixes found here). Crank it up the potentiometer on the kit to max, and then adjust the sound sources balance until your getting your FREAK ON!
  3. Once properly tested, enjoy another beer.
  4. Get a good lighting track. The web has quite a few. I created a custom version that delays the left channel, hence me asking you to use the left channel speaker out for the kits input. The delay approximates the delay of flash to crash you get with real lightning. It's free on this site, look on the project page. You'll dig it.

Notes:

As the sound output drives the lights, play with the speaker balance to get a good bright flash.
