I think most of my data is on the accelerometers still. Which belong to the school.. But I may have something useful buried in my flash drive (or hard drive). I'll look around for it because I'm still very interested in this project, I just don't have much time to work on it.
Now, if you...
I have been running under the consideration that the frictional losses of the gears in the train would be the load on the motor. I essentially need to quantify these frictional losses through measurement.
With that said, I think what I meant by "free-spinning power output" is the power output...
Thanks for the reply
I'm worried this may not compensate for the internal power losses of the motor or the losses in the ammeter.
If I were to do this would I have to have an ammeter in series with the positive and negative terminals on the motor in order to measure the current in and...
Hi everybody,
I'm building a board game right now.
The game consists of a train of gears that I would like to drive with an electric motor.
The gear train can be many different sizes (# of gears) and patterns (size of gears).
What I would like to do with the motor is measure the...
Well I have actually connected an led to a breadboard before, but it has been awhile.
I'm not sure what the scanned matrix driver that you refer to is, and I haven't been able to find anything online about them. If you could direct me to some information about them that would be great. Also...
Ok so I'm going to start this by saying I'm a mechanical engineer and circuits don't make very much sense to me. (So your help is very appreciated)
I'm currently designing a board game and I need to be able to program a large amount of led's.
Basically, I have 217 holes in a gameboard that...
It's difficult to picture what you are talking about exactly but I'll take a stab at it.
(pi*r*s+pi*r^2) = surface area of a cone
(2*pi*r*h+2*pi*r^2)= surface area of a cylinder
where s is the length of the cone side, r is the radius, h is the height of the cylinder, and pi is pi...
The graphs look way better now just a bit of an issue with the magnitude. For an 8 inch test in one direction the results are giving me 2.5 feet. I was only able to change the code just slightly and not really look it over so I may still have some mistakes. I will run some more tests later today...
I'm actually working on adding the current velocity and position into the code right now. I believe, for matlab, I need to have it formatted at vz(i,:) because it is a matrix and in order to place a new number in each successive slot the colon needs to be there. I have tried it without the colon...
It sounds like he placed the container on the scale, then zeroed the scale out to ignore the weight of the container, and then added the gas. By zeroing the scale he can measure the weight of the gas he is adding and not the weight of the cylinder.
I have thought about the integration constants, but I'm nt too sure of what to be using for them or how. I would say just taking the last value i calculated and adding it to the current value being calculated (?) or something to that effect. Like keeping a tally going for each finite integration...
I have the accelerometer set to ignore the acceleration due to gravity. I have considered using SI units (I think i may have at one point), but the initial tests were just to see if the position found was similar to the actual position of the accelerometer.
Hi everybody,
I'm currently working on a project using tri-axis accelerometers to track position. Initially I assumed I would just take the data given in G's, convert to m/s^2 or the English equivalent, and integrate the data numerically to get velocity and position with time. However, I...
