Having gone to the last several Houston Art Car Parades I have always wanted to do one. One art car feature I have not seen much of are LEDs. Mainly because up until recently they have not been bright enough to show up in the daylight of parade time. I have played around with LEDs for a while now and in the last couple of years the light output has skyrocketed and the prices fallen. Another overlooked aspect of make lights seen is to use a fogger, like at a night club/rock show.
My art car idea is to do a tribute to Close Encounters of the Third Kind with Devil's Tower forming on top of the hood. The top of the mountain would be high enough not to allow visabilty inside it because hidden inside is the alien's mothership all LED lit up that would rise from inside the mountain up with fog/smoke/lights eminating from inside the mountain. On some computer command, the ship would go into the classic 5 note sequence: "Re, Mi, Do, Do, So" as it tries to communicate (yes, I looked up the proper notes).
The car itself would modifed to replace the headlights with servo acuated high power RGB LEDs that would be programmed to follow the music blasting beat either up/down or right/left. Behind each wheel and under the car are high power LEDs that run constantly at either off, 50%, or occasional 100% (for music beat). The tail lights would be replaced with a focused red beam high power LED or multiple LEDs somehow rotating. Cooling each tail light LED would be a computer fan blowing thru a tube like thing that has red/yellow flame silk that would move in the wind and look like fire plus the bright LED for efect of a rocket engine. Both hood and truck panels of car are removed. The truck portion open would allow sound/sub/music to escape. The hood would allow fog effect to come thru. Fog effect is spraying glycerin/water mixture sprayed on hot exhaust of car front to back causing entire car to fog up thru open engine, sides, and back. Experamination required to see if fans required to move fog out. The LEDs would play the famous tune to the moter ship as well as go with the music beat.
The project is divided into three parts: Devil's tower on the car, the mothership, and modifing the car for bright LEDs and fog.
Found this at the crub in the 'hood: Chair mat, perfect to make into strong, waterproof, translucent material. I love free/repurposed building materials. Its the spirit of art car! | ![]() |
Formed into a 24" diameter cone stiched up by drilling holes and threading wire and using heat gun to form. Only down side, its heavy. | ![]() |
My purchases from Dollar store (less than $20) plus some cool looking netting with foil tinsle woven in from Michael's Craft store (on sale for $5 roll). | ![]() |
Hard drive parts to be used used as either decoration or to make relief on mothership. HD arms could be make into cranes on mothership. | ![]() |
The bottom of the mothership framed with wire and mesh. | ![]() |
First layer drying consisting of paper towels with cheese cloth as final layer. Used white glue and watered down clear caulking. | ![]() |
April 18, 2015: Umbrella idea not working out because removing shade the metal spokes straighten out and lose the curved cone shape I'm looking for. Did more reading and decided to use paper Mache instead of fiberglass both from a cost perspective, nasty to work with and might become too heavy. Paper mache is cheap made from white glue and paper. It also can be covered to make waterproof. I can also mix up a thicker layar with TP paper, which dissolves eaiser, to make the relief layer I'm wanting. I'm also wondering about other materials with the paper mache. Like wht would sparkles do inside trnaslucent covering when light hits them? I can also make the curve cone shape out of a stuffed plastic trash bag pushed down and made even to be my mold for the paper mache. So off to craft store to get some supplies as well as grabbing some glycerin for the fog expermiments.
April 17, 2015: Plan on experimenting with two things: 1) Fiberglass an old umbrella after using thin wire from old HD motors to create web to hold cloth. 2) Stop by drugstore and buy spray bottle (if I can find one reasonably) and some glycerin and see what it and different ratios of water does when I spray it (by hand) onto hot muffler. How much and how long does the smoke last are my questions (besides seeing if it works at all).
