Re: Intermittent connection on field only

Okay Brian,
Since you don't know me or my skill set, let me explain. My real job is troubleshooting electronic failures down to the component level. A position at which I excel. I know that power can be a definitive issue with many problems that exist and I know both how to diagnose those issues, and how to correct them when they fail or are designed improperly. Power supply noise in digital systems is nothing compared to the noise generated in analog audio systems where microphone levels are in the -60 to -90 dBm (that's millwatt for those who are wondering) range, can require as little 4 microamps from the power supply and where noise is considered bad when it is only 20 db above the theoretical noise floor. I have been telling you for weeks that power is not the issue you have deemed it to be but you have failed to believe me or the others in this forum that are trying to get you to accept that fact. While there are problems (and they have yet to be diagnosed), power is not the greatest of these. How can you even think that those people who are researching every possible failure point have not considered looking at the power supply first? So to borrow from others, stop muddying the waters, perform your tests and bring us real data that can be duplicated in the lab or field and actually correlates to failures of the robot wireless link. Until that time I will only respond to others seeking real answers.

Edit:
Now that I have have seen your most recent post, let me assure you that Team 11 is a long time friend and a team I certainly respect. When at competitions, I would work as hard helping them compete as my own team and I expect all my inspectors to also do the same.
