Mission Possible C

[ScottMaurer19]

Perhaps because I myself am saying nothing of the kind. The FAQ of 1/1 is clear:
"DOES RULE 3I IMPLY THAT ANY ELECTRICAL DEVICE WHICH OPERATES FOR MORE THAN TEN SECONDS WOULD BE A CONSTRUCTION VIOLATION?
Any type of electrical or spring action that operates for more than 10 seconds and still controls part of the action would be a violation"
The temperature sensor is operating for more than ten seconds and controls the termination of the action.

I disagree that the electrical component is what is controlling the action. I would say that the chemical reaction is. If the temperature never gets cold enough then the action fails. Action 1: chemical reaction decreases temp to 10 degrees C 2. sensor resistance increases past tipping point and signals microcontroller to begin the next action.

I'm not sure how else to explain it but I don't believe passive sensors that are active during a timer constitute a construction violation.

I'd also agree with you on this point Scott. I feel like this rule is trying to prevent teams from just having a built in "wait" timer or a spring timer (as the 5th place Nats device had in the last year Mission was a Division C event), since this would make having an accurate time "too easy."

Is A timing step required? In one section of the rules it says you need t but in another it says it’s just for bonus points. What is the minimum time it needs to run, if required? I remember someone said they only included the start and final action and still competed with that.

It is not required. It must run for at least 30s to get bonus points.

My feedback doesn't hold as much weight as the posts that I quoted -- since I'm relatively new to this type of thing -- but I agree with Scott here. The rules are almost asking you to use sensors. (or spend much more time, money and effort to get everything calibrated to perfection, which I don't think most teams can do).

Per Patrick Chalker the sensor is not an electrical timer but the chemical timer does not count for points. He also said that ESs should not double up on penalties and that the 150 penalty should be used instead of tiering.

So would using a temperature sensor detecting a decrease in temperature be perfectly legal for the endothermic action?

Yes. Should be perfectly legal.

What about active sensors, like ping))) sensors? (I'm not actually using a Ping))) sensor, I'm just giving an example)

Unsure on that
