AI Thread Summary
The discussion centers on developing a tracking device for lost items like purses and keys. Suggestions include using RF transmitters for short-range tracking and GPS for longer distances, although GPS increases costs significantly. Participants express interest in learning more about working with GPS technology and RF systems. A link to a related product, Tile, is shared as an example of existing tracking solutions. Overall, the conversation emphasizes the need for effective communication technology in creating a reliable tracking device.

hi,
its is all about tracking lost things.
we have decided that we will make a device which can be put into things like purse ,keys e.t.c and we will be able to trace it if it gets lost.

but i don't have any idea how to approach for it and could you please suggest me technology which can be use to communicate between devices.

thanks

For how much distance your requirement is?

For near by distances you can RF transmitter/ Receiver will be enough, but if you are trying to make it remote, then a GPS system is needed but of course the cost will increase exponentially.

could you please get me some information ,from where i can learn how to work with GPS and transmitter/receiver?

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
