creating 1x16 logic or 2x8 logic and combining them
Minor question about your relays.  Do they drive nice from the 5V supply through a CD or LS chip?  Usually I'd put in a relay driver chip between the logic and the relay...

Logic to find the exact position of the object.
For example, let's assume a non-linear sensor.  Two of them, in fact:   That when a 10lb weight is put directly upon it, it measures 10lbs.  (I'm doing this in...

Logic to find the exact position of the object.
How to build a truck scale is a solved problem.  Everything on from that is engineering (and, hopefully, homework problems for budding engineers!).  S.

Logic to find the exact position of the object.
To be more helpful (what, me?) I think you're overcomplicating this.  Sensor S2 is redundant with weight on the scale.  The logic therefore simplifies to:   IF (No...

Analog Sensor
I'm a bit late to this, but in my personal experience 'shiny black electrical tape' and 'white paper' look almost identical in the infrared.    Just because your eyes...

"Armored" cable?
Is there a reason why you don't want shiny metal conduit?  I think it was avrcandies who first pointed out ordinary conduit - it's practically designed to pull wires through...

Note further that home improvement store 'conduit-style' cable also will attach very well and securely to 'electrical box' enclosures (bare conduit will need 'fittings'). ...
