Mission Possible C

Can someone post a link to the website that Chalker talked about the laser guidelines? Much appreciated!

How do they expect the laser to be operated by a human if it is in the box during the run?

Aren't lasers illegal electronic components as per rule 3.i?

What if you are using heat given off from a battery? The heat is a result of the chemical reaction within the battery, so could this case be argued as E - C, C - T? or would it just be electrical to thermal?

If I burned an object that produces light, and then does the next task with that light, would it be Chemical » Electromagnetic Spectrum? Or does the burning count as thermal rather than chemical?

The point is, in Mission Possible, lasers are not legal, simply because they aren't being directly controlled (not to mention the fact that they probably aren't allowed under the electrical component rules either).

I think that should count as chemical to EM. It would be difficult for an event supervisor to disagree with this.

This actually bears pretty closely on the previous conversation. If the student lit the candle with thermal, you would score thermal -> chemical -> EMS? Does that mean you would score a switch turning on current from a battery as mechanical -> chemical -> electrical? I'm pretty likely to be running this event at regional this year and it will be my first time as supervisor with energy transfers instead of specific tasks, so I would really appreciate input from more experienced people such as yourself.

ETA: I think I can see a way to differentiate the two cases. The switch doesn't actually do anything without the battery, so it isn't two separate actions. If the candle is lit with nichrome, though, the nichrome is clearly changes electrical to heat, and then the candle would change the heat into light. If the candle is lit with an igniter I don't see how you could know that it was the candle's light and not the igniter's which activates the sensor. I still would have trouble scoring see e -> t -> c -> EMS, though.

For you, where is the line drawn? You definitely get e -> t; electricity to a nichrome wire is a pretty clear energy transfer. The thermal to chemical to EMS is definitely happening (presuming the light is triggering the next action in the chain of events)...would it (in your unofficial opinion) not count because the match (if not homemade) is a "blackbox" that shouldn't score a transfer? If that's the case, do you think this should count as a t -> EMS transfer (inputting thermal from the nichrome wire, getting out light from the match)?

Yes, that is pretty much my current thinking. I was only coaching for the last two years of the old Mission when the rules were similar, but that is how I recall the black box rule being applied in the past.

Can someone point me in the direction of any relevant written rules that explain the black box concept? thanks
