Heres video of the visualizer running on the front of my house to give you an idea of what it is.
Step 1: Gather Materials
- A windows laptop, with Winamp and Milkdrop (included in the winamp download)
Ideally: something fast with dedicated graphics
I use: a Lenovo Thinkpad T61, not quite hefty enough but works kind of, again if you don't want it to crash in the middle of a show you'll need a fast computer, I'd say at least 2ghz preferably faster and if you want smooth video you'll need a graphics card with 8 or 10 mb of dedicated memory (you can find more on system specs in the software documentation links on the last step)
- A projector
Ideally: almost anything will do, as long as its bright and of reasonably high resolution, Remote is very good to have but not completely necessary
I use: A Sharp Notevision XG-C55X with the short-throw wide angle lens
Anything that will pick up the beat of the music will work, a shotgun mic for a camcorder would be perfect
I use: a regular old microphone
- Microphone Stand and boom arm
Needs to be sturdy and well weighted
- Amplifier and spare battery
Nothing big or fancy, just enough to pump the mic up to a strong line level input for winamp to use
Screwdrivers and a knife should be all you need to fix any little hiccups with any cable or the mic stand, a flashlight will come in handy cuz it will be dark and you will need to see
- Clipboard, pens, paper, post-its
Clipboard makes you look legit, write down all you winamp shortcuts and presets here for reference, post-its on the laptop for frequently used keys
To cut the edges off the projection and hold cables in place
-Various other connectors and adapters
nothing in the little baggie is used in the setup described here, but bring along extra parts and little bits for on the fly configurations and emergency set-up changes
- VGA/audio cable
A long (mine is 100FT) VGA cable with built in 3.5mm audio, video MUST be high quality, audio is less important here but if you're going to invest in a long, expensive cable you may aswell get one you'll be able to use for something else
- miniphone cable
3.5mm audio extension cable, again audio quality isn't super important but there's no reason to buy a bad one, they're cheap
- Microphone cable
XLR to miniphone cable for the microphone
- Extension cord
- Projector power cable
- Laptop charger
- Laundry sack full of clean white sheets
most clubs and other live music venues will be mostly matte black, you may need to pin up something to project onto
- Thumb tacks
to hang the sheets
- Rubber bands
for cable management
To test visualizer and audio cables, record the band during the event, apps if you get bored
Step 2: Projector Connections
The projector power cable is plugged into the extension cable which is run offstage to an available power outlet.
In the previous step I mentioned that a remote is good to have, I do not have the remote to my projector as I picked it up second hand but if you have access to it a remote is super helpful for turning the projector on or off during a show without interfering with the band, if something goes awry wile the band is playing, like your computer crashing, you can't go up on the stage to turn the projector off until the band finishes which means you'll have to leave whatever default screen your projector gives (the sharp notevision logo in the next step for me) up on the wall until you can get on stage or the projector shuts down automatically. NOT good.
A projector dowser would also come in handy but is waaaay out of my budget... perhaps I'll have to build one myself? ;)
Step 3: Tape the Lens
Step 4: Audio Setup
Step 5: Laptop Connections and Software
This ones important. Winamp is a free open source music player. Get it here:
when you download winamp, make sure you don't uncheck milkdrop, which is our visualizer.
The full documentation for milkdrop is available here:
But I'll highlight the basics for this application right here.
First set winamp to use line in, to do this strike CTRL+L (open location) and type in "linein://" then hit play. Next open up milkdrop by pressing CTRL+K to pull up the list of winamp visualizers, select milkdrop 2. Once you have milkdrop open put it in fullscreen by pressing ALT+ENTER. Thats the basics of it!
Here are the keyboard shortcuts I use most often, the whole list can be found in the milkdrop documentation.
BACKSPACE: return to previous preset
SPACE: transition to next preset
H: instant Hard cut (to next preset)
R: toggle random (vs. sequential) preset traversal
L: load a specific preset (invokes the 'Load' menu)
scroll lock: lock/unlock current preset
Y: enter custom message mode
##: load message ## (where ## is a 2-digit numeric code (00-99)
of a message defined in milk_msg.ini)
*: clear any digits entered.
DELETE: clear message (if visible)
F7: re-read milk_msg.ini from disk
CTRL + T/Y: kill song title and/or any custom messages
I won't go over how to configure presets or custom messages here, that could be several instructables. Milkdrop has a TON of features like sprites and completely configurable presets and all sorts of nifty stuff. If you're interested in using milkdrop for this or any other application then go check it out. www.nullsoft.com/free/milkdrop/
