DozyWannabe,
But at what cost in terms of engineering complexity? The more components involved, the higher the complexity, and the higher the probability of component failure. This is one of the first axioms we learn as engineers.
I reiterate: At a very low cost. Letīs segment qualitatively first:
1) R&D: Very low cost.
2) Product Engineering: Low cost (We could quantify)
The integration to existing structure i estimate to be not a relevant issue.
I posted this possibility with all implications previously "self questioned" (this forum requires a fascinating degree of attention).
About "Circuitry complexity and Failure Rate" we could implement a better one with less components and simpler circuitry, just using denser Integrated Circuits.
In summary, The cost/benefit IMO is good for an improvement. For an investigator "High Quality recording of facts" is obviously good.
