In Regional yesterday, I reviewed with them after each run. I ask student to come check the distance we were measuring, also let them know if I checked any violations. A few top performers missed "the Vehicle's Measurement Point is over the Start Point". The tolerance I gave is the "+...

Thanks Coach Chuck. Cannot agree more.

Hi, Just want to see if it is we just got smart and patient kids or the Freedom Flight really did an excellent job for the design this time. 3 planes build by 3 pairs of students ALL fly pretty good the first time to try (~40 seconds), without any adjustment, or advices from me. Normally, I am happy...

If the competition will use SkiCiv, please start to play with it as soon as possible. Treat it as a computer game and try to find out its laws. It does not follow physics laws exactly. Try all kind of possibilities, go extreme.

Just change regional to State rule.

I asked FAQ about external ADC, the answer was no, then changed to not very clear.

I will allow you to use the stm32 and external ADC if I run the event. But, please if possible, make the ES's life easier.

If only 12bit, you can use Arduino DUE.

Thanks for the link. I got your idea. Yes, the output of the reference resistor is way more linear with smaller reference resistance. Once they are linear, it is possible to get 0.1C, it needs 750 points and ADC has 1024 point. Maybe you can reduce the error at 0 degree by switching the ADC range? I...

Show me your setup and calculation. What I did is for 10K reference + 10K thermistor. The 10 bit ADC only has 1024 different values (0-1023). 0-75 degree C to 0.1C, you will need 750 different values. With thermistor non-linear curve, it is very unlikely you can get 0.1C with 10 bits ADC. Still poss...

I thought low battery would only impact a linear analog to digital sensor, not a thermistor? I tried switching batteries and the readings all remained the same. For reference, two weeks ago the device would read a voltage of 395 for 15 degrees, but now it reads a voltage of 380 for 15 degrees. Noth...
