Re: Game On C

Are two player games allowed? There doesn't seem to be anything against it in the rules. Is this something that I should ask the regionals event organizer to see if they have enough people for a two player game?

Re: Electric Vehicle C

On the other axle put a quadrature encoder (nice, high count/rev one) and hook the controller and encoder into a microcontroller (actual microcontroller, the raspberry pi is a computer and won't work well for this) so you can watch the current position and control the speed. I've been looking at in...

Re: Using Arduino Programing

Have any of you guys come up with a way to determine if the vehicle is moving in a straight line, so you can account for the distance (using trigonometry) if it is moving at an angle?

On another note, has anybody encountered the problem of the Arduino not being able to power the motor?

Re: Crime Busters B

We definitely saw a reaction; it wasn't a big one, but it was a reaction. We have the same problem with our Iodine and H202. No reaction when practicing but at regionals there was a definite reaction. Was it delayed? If so, do you recall the approximate time between when the HCl interacted with the...

Re: Crime Busters B

On the wiki, it says the aluminum has a delayed reaction with HCl. However, when I tried this at school, I didn't seem to find any reaction whatsoever. I'm wondering if our HCl was just weak, or if nobody else saw a reaction with aluminum in HCl either.

Re: Crime Busters B

I just wanted to ask: how exactly do you test the plastics? That was one place we didn't do well at one of our invitationals. Don't feel bad... You're not alone! First, let's discuss the theoretical intent... Supposedly, each polymer has a specific density, ranging from around .90 grams / cm3 to as...

Re: Crime Busters B

In the rules for Division B, under Polymer Testing/Natural and Man-made Substances (part III) it says "No burn test allowed but burn results may be provided."

Re: Scioly Assassination 100: Mafia Reborn

The sassy mentions elementary, so perhaps that could relate to foreverphysics (since she has "I am Sherlock" in her signature, "Not so elementary my dear Watson")? It's the only protect I could think of, without having to decode those numbers.

Re: Would you rather?

Mandarin, it seems to be more helpful.

Would you rather place first in nationals for your favorite event or win $5,000?
