AI Thread Summary
The discussion focuses on controlling a single pin in a 1x1 meter array of 40,000 pins using electromagnetic waves. The user seeks advice on how to manipulate one pin independently without affecting its neighbors, expressing interest in alternative methods such as using water or air valves. Suggestions include wrapping coils around each pin for individual control, though this may not align with the user's vision of remote control. The challenge lies in insulating the pins to prevent interference from adjacent ones. Overall, the user is looking for innovative ideas to initiate their project effectively.

Hello i am an Electrical Engineering undergraduate student at Iowa State University.
My purpose here in this thread is to ask anybody interested in my idea, I am asking an educated contribution on how to control a single pin with electromagnetic waves.

Lets go by parts, the model i am trying to research is a 1x1 meter square that has 40,000 pins set every 0.5cm to each other. This makes the surface area of the square an array of symmetrical positioned pins. The part i am researching is how to control 1 pin with electromagnetics. If this is an easy way of doing it suggestions needed are what, how can I start controling that 1 pin in order to move upward or downward. Is electromagnetics a good start or perhaps I should move on to some other control method?

Thank you for your interest in this topic dear reader I wish I can read some really valuable questions in the morning and hopefully read some new ideas to do this.

Once I have controlled one pin I can control 2 and so on, the idea is simple but challenging.

Once again thank you for your time dear reader.

PS: I am going to rest ill check post first hour in the morning.

You can simply wrap a coil around each pin and power each coil individually to move each pin independantly - but I'm guessing that isn't what you were planing!

If you are planning some sort of remote electromagnetic field focussed on each pin in turn and just moving a single pin without disturbing it's neighbours - tricky.

Yes indeed that's exactly what I mean how to insulate them to avoid stimulation from their neighbors. The part I was thinking is powering each pin with water or air controlled by a valve, but please if you have any idea to give me a start on this project will be really satisfying.
 
Well, if you had a good CO2 laser, you could design a optical position controller and blast the pin.:biggrin:
 
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 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...
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...
