Hi:
Im a (desperate) electonics student looking for help to build a "simple" device capable of measuring the acceleration of an object. I have nearly no limitations, just one, money; and because of this Ive come to you.
What needs to be done is the following:
1. Get the speed of the object at 1 point
2. Get the speed of the object at an other point.
3. calculate: (speed2 - speed1) / total_time.
4. Display result.
1. Collecting data (Easy part):
- The object hits/pass the first sensor/switch [s1]... 2 timers starts [t1] [t3].
- The object hits/pass the second sensor/switch [s2]... the timer stops [t1].
- The object hit/pass a third sensor/switch [s3]... timer starts [t2].
- The object hit/pass the fourth sensor/switch [s4]... 2 the timers stops[t2] [t3].
-?- I belive both times must be recorded, saved or something so we can use them later.
2. Calculating (The other part):
- Calculate speed1 = D1 / t1 //D1 & D2 are constants.
- Calculate speed2 = D2 / t2
- Calculate accel = (speed2 - speed1) / t3
- Display result
And thats it...
I found some related proyects and information on the internet but the problem is they are too expensive, and if they are not, i cant figure out how to bring all the stuff I need together.
If you have any ideas of how to do this, or other way to achieve my goal (calculating the acceleration) I will be deeply thankfull.
Im beging, Im clueless and Im ignorant... I want to learn, Im not afraid of any idea I just need some guidance...
Thank you
By the way sorry for the large post and the crappy english
