Automated F5B-F3B base system

I have an idea, well calculated, clean and partially proven.

Based on simple and easy components.

I need a good "master of elecronic" to build this. It can be open project with one thing only.
I will buy first working sample for cost of components.

Is anybody interested?

Please PM

Them what do you propose?

Keep in mind in the thread there has already been talk about a transponder type system.

The problem is making it.

The system it will be optical with some very easy and clear base. No special software, no heavy loaded "base A-B" equipment.
Battery powered, have no wires, no radio noise. Easy and clear. Fast and precize. Main components is Japan, second one is China made.

I need the elecpronic's minded person to do this.

I think it would help if you wrote what you actually have in mind, then someone may know someone who can do what you want to do.

Just giving vague details is not going to help.

Infact, if it is optical why is it any better then the above project?

I don't see there is a big problem getting the signal back to A or heavy loaded Laptop's as you discribe it. The software is already there, it works.

The problem is the optical part.

There is a battery powered laser level that puts out a beam of red light on every wall.

If it could be set up at a base, and pointed in line with the end of the base.....a model passing through the beam of light, could signal the crossing of the base.

Maybe this is the kind of idea that the OP is thinking about......I have thought the same thing.

I have kept quiet because I don't want to hinder the Aussie attempt.

Kenny, the light beam would have to cover not only one altitude. You would need to place emitors and sensors up to 300 meters high.

I was thinking the light beam could be set on the ground and pointed to infinity....the sensors would be on the model, and as soon as the model crossed the light beam, a signal could be sounded.

In that case the sensor on the plane would need to cover 360 degrees of view on the model so that no matter how the plane is orentated when it goes past it will see the signal.

The special beam from the emiter would have to only be in one "plane" without any big % of error when you get further away.

The sensor on the plane should not get triggered from any other source!

I wonder if that would be possible...... sounds like something from one of those movies where they break into a highly secured vault (lots of laser beams on the alarm).

My feeling is the emiter will not emit a strong enough signal in day light or if you set the sensativaty high on the sensor it will go off all the time from sunlight.

Who knows.

It's just a thought I had.
I'm logged on, and typing on my Droid....These days, anything seems possible.

A laser system could work. Afterall the police do use them in speed traps and are more accurate than doppler radar. Here you would want to use a LIDAR principle rather than dispersing your laser energy on a line. - this is my winter project as the webcam system will never be able to reach the FAI requirement on accuracy at a reasonable price (cost of high speed cameras is excessive).

LIDAR, let me guess, is that where you spin a single beam of laser round really fast?

try a dvr that is set to start up when the pixals are changed

so when any motion, or change in pixals the camera will start recording

but modify it to trigger a buzzer instead
