Very nice work Scott. The device is pretty clean, although given more time for a rebuild, It could have probably done without some of that hot glue lol. Im sorry for your troubles with the ES's ruling, the rules this year were certainly very complex and despite the immense amount of time and thought that gets out into carefully wording each and every sentence in the rules, even the large panel of nationals people that average 2-3 decades of SO experience can't anticipate every situation. Im glad you (and Nicholas) got the issue resolved and still landed in the top 6 because you very much deserved it

Thanks!
The hotglue actually had a functional purpose even if it pained me to use it. If I needed to repair/replace/modify most things on the device then I could simply heat up a blade, melt the glue, and pull it off. I actually ended up needing to repair both the power distibution board (the screw headers were bad) and the electromagnet and the hot glue made it easy--although not pretty--to do.
If any of the people heard the screaming from the front left when were called for mission it's because we were completely taken by surprise with that one

Hey guys!
Here are some pics of our mission for the Michigan state competition this year. We placed first with all twelve tasks and a chemical timer. The entire mission was built in 5 weeks, following the completely different regional mission, and had we gone to nationals, we would have reduced the size a little more and practiced with longer run times on the chemical timer. Our mission has been very reliable and we've had no issues with it.

Hey Scott, how did you calibrate your timer? You used Alka-Seltzer in conjunction with the balloon task, right? About how long was the maximum time you could get with the timer?

I just tested and tested and tested and recorded the temperature with the time.
I was aiming for a time of 2:35 so that all my tasks could complete with plenty of time and if something went wrong I had like 15 seconds to fix it.

That's exactly what we did for our alka seltzer chem timer/balloon task also. We used different numbers of similar sized ice cubes to change the temperature and reaction rate. We kept the number of alka tablets constant. (1 tablet)

I ended up taping both sides and using the extra strength alkaseltzer because it was slower than regular for some reason
