Re: FIRST: take advantage of your mentors expertise

As I have offered with the electronic motor controls and with LinuxBoy's CAN terminators. Anyone that requires a little prototype help with this please let me know.

The issue of sample speed plays to how fast a 'glitch' or transient you can catch. For example let's say that you hit a bump and your D-Link AP radio connector opens up for 1uS. If you happened to take a sample before or after you might not see that happen. It's an effect of taking discrete samples and it's part of quantization.

The idea of holding off capturing huge amounts of data, and limiting the duration of the data you do capture by time is a very good idea. It means that you could sample more frequently during the time you do sample because you suspect you have a problem you definitely want to catch. This also means that you limit the amount of pointless stuff you need to see later.

Also if you have a sample buffer fast enough to collect data very quickly there's nothing stopping you from using it slowly as well if you desire. In that way if you wanted you could still capture all of the voltage you monitor throughout the duration of a match without additional hardware. You just need to be able to adjust the trigger and sample speed.

Yes these terms are all familiar to people that use oscilloscopes.
