NOT using his circuits , So i may beable to increase range with a better circuit with better discrimination, Iv seen the line detectors you mention , I will make somthing like that.

Is'nt trying different things what its all about ?

Steve_c

Yep. As I have said more than once, there is no single solution and it will probably require more than one method regardless.

Yup

Robot labs around the world have and still are spending $/£ millions on this very issue.

We are trying to do it on a shoestring.

Steve_c

Yes i said that before,why i test many designs to make better changes.

ME not on shoestring budget,so hope my tests will help others that are on.

Time is my only problem,so many projects ,and this has been my favorate post.

Been a 2 years since i did testing on so many ideas of homebase finding and docking.

ON the chickets chirp idea ,i have all prts to build it,except for micro i am using EZB and transducer i may have some ,but i dont now its the same frequency he is using 4500hz,microphones i have plenty of.

TEST equipment i have almost every piece of equipment to test it,sounds like a fun sensor to make and test

Well your at it maybe look in to a slightly longer range.

10 m is what im after. That would make it far more usable.

in my home .

Good luck with the build.

Steve_c

THANKS for idea.i might be good to add a longer range to it and shouldnt be hard also. i printed it and place on my clip board on my wall in my design area with a few other designs i am making .

Cool , Cant wait for the results , hope you can get it to work.
