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 controled 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.
