I did not try to "scoff" anyone and if I did miss something - I do apologise.
I have asked some questions twice to understand the process. It was vital for me and following that, I came to draw my own conclusions. I have just only joined this site and this thread sometime soon after, it was already going for a while. I am a newbie.
All possible "sensors" presented and I can think of, do fall into one of the three categories (thinking of horizontally rotating and spinning bobbins):
A) no power supply needed,
B) power supply needed,
C) power supply needed and other means of the communication needed,
“A” is the obvious choice and the number of sensors required is presentable in the my (“A” sensor) solution utilizing 4 sensors spaced 90 degrees apart
and very much inspired by other members of this thread (magnetic). (
THE SOLUTION IS NOT MINE, THE 4 SENSORS AND WHAT FOLLOWS - IS.. )..It means - I am listening to what you do have to say and I had backed-off from other solutions I have proposed earlier. This is my learning curve I do need to respect and obey, and expect your reaction to it - in kind.
When I did say ALL, I did really mean – ALL but one.
The only other valid solution I saw, involves the optical “pattern sampling” of the "sock", and that one - is mine alone within this thread.
The OCR software is capable to distinguish between “A-to-Z” and “0-to 9”. I am very sure, it can distinguish a single “character” of the pattern detected on the production line against the
expected (wanted) sample. For this, perhaps even a PIC could be usefull. This "novelty" has not been presented earlier, except by me.
I do fill quite bad for that, becuse I am taking away the job from a working fellow, but the macro camera would do the same job for no greater cost than required for the initial setup + some conehead type of - programming. The additional benefit is hidden in the the fact.. that - the camera will not fall asleep so much as may the "working fellow" and in the end, - I may get my "sock" cheaper
.
The reason for me to feel redundant here is - that I do feel; the answer - has already been found. I have stated that already earlier.
