Welcome to Spring 2015

Welcome! I’m glad you’re here.

Please tell me a little more about yourself by filling out my new student questionnaire.

Once you’re done, go to your class tab and look around! If you like to use remind 101 (I send you text messages about upcoming assignments, but your phone number stays private, and so does mine!) sign up.

Each class tab has a copy of the syllabus, and summary of topics that we will cover this semester.

Microcontroller Project

Today we will be working with the Sparkfun Inventor’s Kit.


To get it working we will need to download 2 things:

The Arduino Integrated Developer Environment (How we can tell the redboard what to do.)

The FTDI USB Drivers (So the computer can talk to the redboard.)


Other useful information:

MicroController Lab instructions are here.

The Inventors Kit guide (This has all of the steps, and programs that you will need to upload to the redboard.)

11/21 Fourth Period

Thank you all for working so hard on the assignment yesterday.  There’s a new, similar assignment today.  Only 3 problems, but much more difficult (and worth considerably more points.)

Some hints for today:

First μ is a prefix meaning micro, or 10^-6.  So when you see 5.7μC, we’re talking about 5.7*10^-6 coulombs

Second, remember all of your rules about vectors, vector addition, and how to combine vectors from 2 dimensions into 1.

A really helpful tool: Hyper Physics Coulomb Force Calculator

For an Electric Field calculation, Q2 is usually just a single electron, or a single proton.  Use the calculator above, then divide the answer you get by the charge of that single electron.

Assignments for 11/21

First period:

For the 9 of you who actually downloaded and attempted the homework, I appreciate your diligence.  Here are some resources for you.

Assignments for 11/20

Today is an easy day! You have webassign about electric force and electric fields. Try this without yahoo answers. If you need help Google “hyper physics.” It’s a great resource from the University of Georgia.

REMEMBER!
Force is in Newtons
Charge is in Coulombs
Electric Field strength is in Newtons per Coulomb (N/C)

If you need help, email me!

If you wrap up early, get some work in on the wiki!

STEM Python Project

The program that you’re writing will be graded on it’s ability to do the follow.

  1. Questions that you should ask the user.
    1. Ask for Velocity Initial
    2. Ask for launch angle
    3. Ask for launch height
  2. Display the following:
    1. Component velocities
      Vix and Viy
    2. Time the projectile hits the ground
      Bonus points if you can eliminate the negative time!
    3. The distance the projectile travels
  3. Style points for:
    1. Using human readable variables
    2. Commenting your code


This project is due on Nov 25.
