Mission Possible C

[Unome]

I have a question regarding the use of a sensor. In my current design, I use a TMP36 sensor connected to an Arduino to record a decrease in temperature during a certain chemical reaction. When the sensor records a certain temperature drop, the Arduino turns on a speaker which serves as the final action. The reaction takes several minutes for the temperature change. I've used this design at several invitationals, and the event supervisors have never brought up that this might be against the rules. Based on your interpretation of the rules, would this be a construction violation?

If the reaction is running in parallel to other tasks, it breaks rule 3.e and would be tiered. It's hard to tell from your description whether that's actually happening though.

If this is your chemical clock (which it seems like, as it takes "Several minutes" this is not allowed, as the FAQ says that the chemical clock can't be ended by an electric sensor.

I think he's referring to the sensor being electrical and the reaction taking several minutes (electrical timer). IMO the sensor is static unless the temperature changes and electricity is not causing the delayed time. However, per an FAQ, the reaction does not count as a chemical timer.

Thank you, that's what I was asking. The wording in the FAQ is not very clear, but that is how I believed it would be interpreted. I can still use the sensor for the reduction in temperature task?

It would be tiered, IMO. The only reasonable justification for the FAQ is that having an electrical sensor reading the chemical clock would violate 3.i. This would imply that any sensor active for 10 seconds before the next task begins would be a construction violation. The seems harsh and I really, really wish the FAQ was a little more explicit than a simple "no," but I can't see any other way to interpret it.

Why would it be tiered? The electrical component of the action does not take longer than 10 seconds. The reaction does. Even if you consider the sensor as electrical taking longer than 10 seconds than it would be a 150 point penalty and not a construction violation. This means that the action cannot be considered a chemical timer but I have a hard time seeing how it would be tiered.

If the task was not a chemical clock, would it be legal?

It meets the criteria of the task so the task should count for points just not as a timer.

Yes, you can.

Hey guys
Question: I’m using my pulley to complete a circuit by having one end of it lift up a metal mass to an uncomplete circuit and having the mass touch the wires. My question is, as long as I use a simple D-Cell or 9V battery, is this allowed? I’d be using solid core, 18 gauge copper wiring, and only the tips would be a little stripped. However, there would be a period of time where electricity (again, from only a 9v or a D-cell) is passing through one end.
