The Lee-Tseung Lead Out Theory

[Top Gun]

A visit to the electronics component center in Shenzhen, China, helped to resolve the sensor issue.  See Attached diagram.

The first try will use magnetic sensors.

The remaining issues are the programming controls.

A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, control of amusement rides, or control of lighting fixtures.

PLCs are used in many different industries and machines such as packaging and semiconductor machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory.

A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

There is a learning curve associated with PLCs.  Any one out there with such expertise ready to help???

What you don't know PLC's? This stuff was invented 30 years ago! You're TOP GUN and you don't know how this stuff works? I supposed you can ask the Hong Kong Polytech. University Mechanical Engineering students for help but whether they want to waste their time on this circular argument stuff is the real question! Maybe your friend Paul_R can lend you a hand?
He should know something....

cheers

I doubt Paul will help Chris,

He is too busy trying to make a thermopile with diodes.

Isn't this like Hall Sensor technology that has been known for some time now? Or, proximity sensors?
