The Laser Car

Sam | October 21st, 2008 | No Comments

You see, I’m making a laser guided car for the sixth grade Science Fair. There will be a track built up of mirrors reflecting the laser into a guidance for the car. The laser will hit into a phototrasistor, telling it either to turn right, left, or straight depending on which “eye” it hits. The funny part will be that the car will be wearing sunglasses to block out UV light that will completely malfunction the car. Also, the mirror stands will contain a lower elevated infrared LED that will tell the car wether to turn left of right. ROBOTS ARE AWESOME!!! :>)I almost have the main control circuit finished.

HHO

I built from scratch a Hydrogen and oxygen generator using perforated stainless steel panels a 5 gallon jug. Wire, a 57 ford coil and my 97 dodge neon. seeing all of the other companys that charge 500 to 1500 for there generators. i decided id come up with my own design. It works far better than anyother one i’ve ever seen. i dont know the rate at which it produces but wow its enough. I’m getting about 90 mpg. Currently looking in to running the car on only water no separator at all.

Fan Powered RC Car

Chris Dycus | May 29th, 2008 | 4 Comments

This is an RC car I built. It’s pretty quick, as you can see in the video. It’s easy to build, despite its complicated looks. Here are the basic steps:

Cut a base out of balsa wood, making sure to cut away parts for the front wheels.

Mount the front wheels, including the servo.

Mount a fan on the back wheels and mount those.

Rig up a servo arm to press a switch; that will be the GO button. Have that switch turn a relay, which then feeds power from the main battery to the fan. Mount it.

Mount the relay battery and the fan battery.

Mount the receiver, and hook up the servos.

Attach the batteries for the receiver.

And that’s about it! Thanks for reading.

Stop tailgaters!!(the fun way)

I know what you thinking,its just another traffic control submission, but this one is one i believe should be on every car in America these days, have you ever been tail gated all the way from point A to point
B?, i have (a total of twenty miles to be exact) and it drives me absolutely nuts because if you slow down to give them the hint to get off your back, they just think your a slow “granny driver” and continue tailgating in feeble hopes this will motivate you to speed up, also have you ever been driving on the highway at night and some one is on your back with their brights on completely dilating and un-dilating your eyes, this is a very dangerous situation?,I this should solve that as well,and i hope my idea soon becomes a reality, aside from honking and showing them your middle finger in a feeble attempt to get them to pass you, there really is nothing you can do, until now, my idea is to make a simple “billboard” that will elevate from under a hidden “door” similar to a VCR opening, the sign would illuminate any sentence or “gesture” you may want to express to that person, the sign would be powered by the battery of course drawing about 15 amps and would run on a belt motor inside the trunk, the sign itself would be like an LCD screen, or like the signs for drive-ins, i will start this project after my FM transmitter. comments or suggestion would be great!

MPG Display

Josh Monroe | April 22nd, 2008 | 10 Comments

I am almost done building a display for my car that reads data from the car’s OBDII port and computes instant miles per gallon and trip miles per gallon then displays that information on an LCD so that I can tune my driving to get optinal fuel economy.
