Re: It's About Time C
Can the device be a chemical reaction? It doesn't explicitly say that is forbidden in the rule book but it says on the SciOly page that you are not allowed to.

Re: It's About Time C
Ouch, this event has changed quite a bit: the device needs to emit a consistent signal three times at randomly chosen intervals between 10-30s at regionals (up to 60 at nationals) for two trials instead of one signal after 300s (at most). I had a quite accurate hourglass-esque device that is now worthless and I need to start over for this year.

Re: It's About Time C
Id love for some ideas in which yall were going to do the three signals thing. Was brainstorming with my class and we were struggling. I mentioned maybe a balancing bird type of idea with a water based device, but wasnt sure how well that would work. Glad I wasnt the only one stumped by this. I see mention of a pendulum, but what would be the signal in that case? Would the pendulum hit some sort of bell or something? Thanks for the help!

Re: It's About Time C
Glad you brought this up. I don't have a clue on how to implement three signals for a Sand Clock. There is not enough information in the rules document. Any insight would really help.Weavy wrote: ↑January 17th, 2023, 6:05 pm Id love for some ideas in which yall were going to do the three signals thing.

Re: It's About Time C
How about this:
The sand falls into the pan of a balance. When the weight of the sand exceeds the weight, the pan falls down, which does two things:
1. Dings a bell (your signal)
2. Hits a lever that releases a mass to fall into the pan on the other side of the balance.
Repeat...

Re: It's About Time C
A month ago, Virginia Science Olympiad made a good video where they discuss the event.
