Month: March 2016

We are in 506 today.

1. input/output review as a class.
2. field trip to stoplight – bring your worksheet.
3. what input/output sequence do you want for the stoplight?

3d printer that runs from your smartphone – $99!!

college student 3d prints his own Invisalign

today-

1. on campus field trip to experience a real world scenario where user input controls output
2. discussion – Arduino INPUT and if/else statements
3. email me part 3 of your completed blink sketch.  Copy/paste the URL of your circuit design in 123d.circuits.io and email it to me at rpmteacher@gmail.com.  Make sure that your last name is in the name of the sketch (program).  You can change this in 123d Circuits by clicking on the GEAR icon in the top right hand corner of your window.
4. finish your Musical LED.  Demo to Mr. Milstead listen and watch for credit.
5. begin your Arduino breadboard and coding by clicking here.  Start by building the breadboard. Then work on your code.

1. If you haven’t sent me your first Red Yellow Green circuit from 123d.circuits.io then look to Monday’s agenda and finish it today.
2. Done?  Head to the middle table to learn about circuit-building on a breadboard.  Then take one Arduino and one breadboard to your computer.
3. Test your Arduino and breadboard connection by setting up the blink sketch that you wrote last week.
4. Musical LED – complete your circuit and program in 123d.circuits.io.  Then make it “real” by setting up the same circuit on your breadboard.  Then use the Arduino IDE to upload your sketch (program) to the microcontroller.  Bring it to life!

Ready for more?  Add an RGB LED and get one LED to become many colors.

Troubleshooting:

>if you are getting an error that looks like this:

your Arduino is likely not connect to the correct port.  Things to check:

1. is the cable connected to the USB port on the back of your computer?
2. is the right port selected?  In Arduino go to Tools, Serial Port and choose the bottom port.

today-

showcase Arduino project: Mjolnir (Thor’s Hammer)

Introduction the Arduino IDE (integrated development environment)

Search your computer for Arduino and open the program.

1. Complete parts 1, part 2 and part 3 that we started on Friday.
2. Done?  Copy/paste the URL of your circuit design in 123d.circuits.io and email it to me at rpmteacher@gmail.com.  Make sure that your last name is in the name of the sketch (program).  You can change this in 123d Circuits by clicking on the GEAR icon in the top right hand corner of your window.
3. Now move on to the Musical LED project.

 

Introduction to Arduino- today we are in room 127

Arduino and 123dcircuits introduction

1. login to your computer
2. point your browser to 123dcircuits.io
3. you SHOULD be able to login with your tinkercad account. If not, create a new account.
4. once you have created your account then watch and do this first task on your own.  Click here for the tutorial.  Important skills:
   1. adding components
   2. wiring
   3. changing wiring colors
   4. purpose of a resistor
   5. negative and positive legs on and LED
   6. saving projects
5. Done?  Show me and go to Part 1. 

 

today’s goals NOTE this is the last in-class workday for this project. All other work must be completed during tutorials.  We begin a new project on Friday.

complete axle cap designs in tinkercad.com
submit your design for printing – designs needed from Jake, Sofia, Nio, Vinnie, Hayden, Ivan, Randy, Ian
assemble gears on panel

axle cap assignment 

due to be submitted by the end of today’s class.  If you have already completed this section scroll down to Part 2.

1. create four different designs for axle caps that will hold your gears in place.  Make your designs cool, different and share a common theme.  Click here for a video tutorial on this project.  
   1. measure the pencil that you will use are your axle.  Add 1 mm to your measurements to allow for fit, glue and printing.
   2. create a hexagon or cylinder hole that matches those measurements
   3. use a solid cylinder and group it with the hole to create a hollow shell.
   4. use this hollow shell as the base for four different axle designs (one for each axle).  Feel free to take an image from the Internet and use it as the design for your axle cap.  Your image must be converted to an SVG file and imported into Tinkercad.  Click here to convert your file.
2. create all four different designs into one file.
3. submit your design here.  Make sure your name is part of the file name.

 

 

 

today’s goals:

1. complete and submit your gears for laser cutting. Need help?  Watch the video tutorials.
2. create four different axle cap designs in tinkercad.  Read below and watch this video tutorial.
3. done with the above?  Then update your digital portfolio (scroll to the bottom of today’s agenda.

update your portfolio -once you have already finished the task above then update your digital portfolio.  This can be found at sites.google.com.  Create a section on your portfolio website called “CAD/CAM- Gear Project”.

Answer the following prompts in this section of your digital portfolio:
1. What is the overall goal of this project?
2. Describe the different types of CAD/CAM that you have used in this project.
3. In your opinion, which of these types of CAM are the most useful.  Describe why you think this type is most useful and an example of how it is being used in engineering and design.
