On the Top plane, make this shape. Ensure the corner is centetered at the orign. Use Corner rectangle:
Step 2) add teh arc:
Step 3) Lines and make 1 tangent:
Step 4) Turn on “show constraints” and take a screenshot. Make sure that you have the same constraints that mine does
Below is the a screenshot of what your constraints should be :
Step 1) Crate a 2.5 by 2 rectangle and use Corner, centered at origin
Step 2) Add 2 points and make them midpoints:
Step 3) Add a construction line between the midpoints (link)
Step 4) offset the perimiter by 0.25
Step 3) Extrude the outside only:
Step 4) Add a 0.1 Chamfer to one side:
Step 5) On the other side, add a small filet.
Step 6) Play with the chamfer and fillet(increase sizes) until you understand the difference. In your google doc paste a screenshot of the 3 shape so I can see the filet and the chamfer . And explain the difference, physically, between the 2
Step 1) Make a corner rectangle that is 2.5×2 , centered at the origin (all black lines 🙂
Step 2) add 2 points to top and bottom and make them “midpoints”
Step 1) Create a new empty sketch and draw 2 lines that meet. The lines should be 3 and 4 in length and should connect at one point. They should be dimensioend to be 3 and 5 but they will be blue and that is ok
Step 3) Dimension the angle to 45 degrees. Link . You shoul dhave something liek this (your orientation/angle might be different)
Step 4) connect the vertices to make a triangle. Picture:
Step 5)
Step 6) Add a chamfer. Take a screenshot and submit on classrom
Step 1) create a sketch called “Favorite Sketch” on the front plane:
Step 2) Draw a line then ensure it’s vertical : (doesn’t have to be exact but about this size and location)
Step 3) Draw a circle , radius of 3. blue is fine. Just make its radius dimensioned to 3
Step 4) Make the line a mirror line and reflect circle over it :
Step 5) N ow, extrude the circle. What happens to the other circle? Does it matter which circle you extrude? Paste the final photo with the extrude in the assignment
Step 1
Step 2
Step 3 (
Step 1 : build forever → show number → temperature. ( how to link)
Flash to device (link).
Step 2 : Scavenge Hunt Battery pack on, roam the room. Record on a paper table. Write each number
Extension: The micro:bit thinks of temp in Celsius. Convert that reading into Fahrenheit for display and your logs; the micro:To do this, you must be able to make a variable and then implement the conversion formula. Here’s one way: (how to )
Step 1 : Two Numbers 1 Device : button A → temperature, B → light level (how to link)
Two sensors, one device.
Flash once .
Step 2 : Scavenge Hunt Battery pack on, roam the room. Record on a paper table. Log both temperature and light at each spot, and record a second reading at each spot 30 seconds apart to see if it drifts. 4–5 spots
