Team,

I don’t know if you all know but, you have to go to the office and ask for an "extrodanary absence" form (I think that is what they are called). You have to have every one of your teachers...

Mr.Kibler,

Sorry I haven’t been on the forum lately, I had been checking it and it was stuck on page 40 and about an hour ago I looked at it again and BOOM! There were another 2 whole pages of...

Mr.Kibler,

Here are my answers to your recent questions:

1) How can we use this procedure to help calibrate the CO2 sensor on the ASP?
-Could this procedure work on the ASP-2?

2) What...

:D So what's it like having your braces off? The timing is coincidental because I get my braces off tomorrow morning...! :D

One month until liftoff!

Mr.Kibler,

Mr.Kibler,

Attached is my version of the program with my corrections made. I put *** every time I made a change so it was a little easier to find. Sorry for such a late reply, I got my braces on...

Mr.Kibler,

For Question 1: Pressure does affect CO2 concentrations but I can't seem to figure out how. I think that CO2 concentration would increase.

For Question 2: I was thinking that CO2...

Dr.Allen,

After finally figuring out how to log in to Parallax, with much help from Justin, Andrew, and Mr. Kibler, here are my answers to your latest questions:

"Question #1: What do you...

Andrew,
That is also how I see it, there was a format to the·incorrect constant that we could not figure out. I think we tried find·a converter online and we checked our "What's a Microcontroller"...

Mr. Kibler,

Intrinsic means "belonging to a thing by its very nature". Noise can be defined as any unwanted signal in a system. Intrinsic noise is generated by the element itself. There are three...

Dr.Allen,

What is "noise intrinsic in the sensor"? How could this affect the spikes in the data? Could wrong wiring cause the spikes in the data? I know we have about checked the wiring over ten...

Dr.Allen,

I have not yet learned about logarithms either. I had Algebra my freshman year, and my upcoming sophomore year I will be in Geometry.

Dr.Allen,

Here are my answers to your table:

ppm ·· mV
200 ·· 336
300 ·· 330
400 ·· 324
500 ·· 318
600 ·· 314

Dr.Allen,

For some reason, in my question 2, I did 300 instead of 500. Also, how do you know when you don't need to do the reciprocal? Do you only do it when it comes out a decimal in the first...

Dr.Allen,
Here are my answers to your recent questions:

1) ppm-4000=-250*x (mV-281)

ppm= -250*x·+ (-250*-281) +4000

ppm= -250*mV + 74250

Dr.Allen,

Here are my answers to your questions. I was having trouble with these questions, so I am not fully confident that my answers are completely correct.

Slope=(y2-y1) / (x2-x1)=...

Andrew,

What do you have in your mockup? Is it everything that is on the ASP right now?

Sean

Dr.Allen,

Is 1.4 volts considered the average voltage at ambient? How do we bump up our voltage from being 0.45 volts to around your voltage (1.4 volts) if not exactly that?

Thank you all for...

Dr. Allen,

How exactly do you "...use the lookup table stored in a second slot on the BS2e"? How do you find convert millivoltage to ppm by "...by direct computation of the logarithm or...

Sylvie and Mr.Kibler,

I was lucky to catch the Spain game on Sunday. I think I sat up in my room and watch the entire thing for about 2 1/2 hours. It seemed to me the Spain had it in the bag the...

Sylvie,

I know you want Spain to win the world cup, but who do you THINK is going to win? I believe that Spain is going to win, but I haven't watched any of the Netherland games to see how good...

Mr.Kibler,

Baseball is going great. I play 2nd base, I can catch, and sometimes on the town team (WAC) I play first. We are 4-4. Today is my first playoff game for WAC, and if we win this game we...

Dr.Allen,

You said :"Then the subroutine reads channel 0, and in doing so it recycles CO2pp for the result..."

So when CO2pp is recycled, is it deleted like you deleted the others so we can use...

Sylvie,

I agree with you a 100%. Baseball is America's pastime (at least to me!). The feeling of being at a minor league or the MLB baseball games are just relaxing yet so exciting and you know...

Dr.Allen, Sylvie, and Mr.Kibler,

I have been busy with summer sports and I have playoffs coming up for baseball. Today I looked at the forum and nothing new had happened, and now, I look at the...

Dr.Allen,

It sounds to me·that you are saying that 1.22265625 goes to 1.2207. Is this correct? If so, how does the STAMP go from 1.22265625 to 1.2207? If you rounded it, wouldn't the outcome be...
