Direction Detection Circuit Board Design

Hi,

I currently have a circuit that has manual 'switches' in it.
Currently there is a piece of plastic that spins around on a shaft, hit hits two manual contact switches depending on which way it is spinning.

This is not a good design as each time it hits the switch it 'slows' it down from spinning.

So we want to redesign this system as basic as possible using HALL SENSOR.

So it detects the spinning, which way it is spinning, then triggers opto isolator output depending on which way it is spinning, clock wise or anti clock wise.

New circuit board will
- Detect spinning
- Detect clock wise or anticlockwise
- Send output depending on direction to an opt isolator.

Please refer to diagrams hopefully they show some further info of what I am trying to achieve.

Any questions let me know, if you can't sort this in the next couple of days please don't bid.
