Class 38: Friday, 12/20/24 

  • If you're having trouble with the laser not cutting through...
    • Your wood may be warped -- and at different heights in different places, so the laser is out of focus.  Fix this by...
      • Cutting from smaller pieces of wood -- just barely bigger than you need
      • Finding flatter wood
    • Some parts of the wood have uneven glueing or knots, so the laser won't burn all of the way through.  I don't know how to predict where these will be.
  • Turn in your photo (etc.) via the Google Classroom assignment.

Class 37: Wednesday, 12/18/24 

  • See notes from last class about speed and power settings.

    • The Epilog should be ready to go in D104.
    • Glowforge Settings, etc.:
      • After you click print, check the final position of your design on the wood.  It changes.  Adjust if necessary, then cancel and reprint.  Like this.
      • Use these settings as starting points (adjust speed as necessary)  (Video going through steps):
        • 6mm Birch: 
          • Uncertified material, 0.236 inches
          • Custom or Manual
            • Custom:  6mm Baltic Birch

  • Disassemble fan car parts

Class 35: Thrzdeigh, 12/12/24 

  • Interlocking Joint Project:
    • **Constraint change:  You can choose from 3mm or 6mm Baltic birch plywood (or wood that you provide) for your final laser-cut object.
    • Before you make your laser cutting .svg file, organize your parts in the most efficient form possible. 
    • Before you go to laser cut, cut a rectangle of wood that is just big enough (with a small margin) for all of your batch of parts.  Remove this from our stock wood judiciously, so that others can use as much as possible of the leftover wood.

  • Engineering logs are due on Thursday (9/5), at Midnight -- and on-time submission is 9% of the grade.

Class 2: Thursday, 8/29/24 -- Big Idea:  Engineer a taller marshmallow tower

  • Phones in the caddy -- I can remind people of your numbers

  • Fill out the student information sheet.  If you have already done this in one of my other classes (this year), you can skip it.

  • Take a look at the project grading rubric

  • (about 60 min) Continue the iterative design process.  Copy and paste to add more iterations as necessary.  For full credit, you must have at least 3 unique iterations (versions of your design or tests of some aspect of your design -- not including the final build on the contest day).  Each iteration should be an experiment that tests an idea that you have about how to achieve your goal.

  • (10 min) Documentation Check– go back and make sure that you have filled everything out properly in the spaces above.  If you need any pictures, maybe you can still take them before cleanup.

  • Clean up.  Mr. Stapleton will check your area ( I forgot to do this formally last time, but everything looked great! )

  • Have a great weekend!  :-)

Class 1: Tuesday, 8/27/24 -- Big Idea:  Welcome, and start engineering a taller marshmallow tower
