Selfie Ring Light Tutorial #3: Components and Joints

This is Tutorial #3 in the Selfie Ring Light Tutorial series.
If you have not yet completed the previous tutorials, you can follow them from Tutorial #1 here.

In the previous tutorial, you created a Layout Sketch – a fundamental part of the design.
Inside it there was an outline of each component – LED ring, Battery Box, Digispark and Tact Switch.

In this tutorial, we’ll:

  • Insert each of those components into the design, and
  • Create and align joints to fix them to the outlines in our Layout Sketch.

This keeps the components in the right positions.


Theory: What is a Joint?

Components aren’t naturally fixed in place.
They can move, rotate, go anywhere!
This would make larger designs difficult.
(Oh no, I changed a dimension; now all my screws are in the wrong place!)

Some designs have parts that move; a hinged door, a sliding part, or something even more complex.
How can you design something with motion if the components aren’t connected?

A Joint connects two components.
Different Joint types allow for different types of motion.
To create a fixed connection (no motion) we use the Rigid joint type.
(You will use other kinds of Joints more in Term 2)

The Moo Brew vending machine hatch design uses several Joints – this video was made completely in Fusion 360!

The two components in the Joint are aligned along ‘Joint Origins’ chosen when the Joint is created.

Lets do that now…


Step 1: Preparation

  1. Open Fusion 360.
  2. Show the Data Panel (by clicking on )
  3. Navigate to the Selfie Ring Light folder.
  4. Open the ‘SRL test mk1’ design you created in SRL Tutorial #2.
    (Double-click on it, or right-click and select Open)
  5. Navigate to the components folder, so that the Data Panel shows the electronic components:

Step 2: Insert LED Ring

  1. In the Data Panel, right-click (or two-finger click) on the LED Ring component.
    Select ‘Insert into Current Design’.
    (This may take 5-15 seconds, be patient and wait for it to appear in the canvas…)
  2. When the component appears, click on ‘OK’ in the dialog:

Now the LED ring is in the design!
It’s not connected to anything yet…


Step 3: Joint LED Ring

In this step, we connect the LED Ring to the parent component’s Layout sketch.
Watch the video first, then follow the steps.

  1. Select the ‘Joint’ tool.
    (Click on ‘Joint’ in the Assemble toolbar, press j, or find it with the Search tool)
  2. Click and drag the View Cube around until you can see the back of the LED ring,
  3. Hover the mouse over the rear inner edge of the LED Ring.
    A Joint Origin will appear in the centre.
    (A component has many possible Joint Origins – it is important to choose the right one)
  4. Click on that edge, and the LED Ring is selected as the first component in the joint.
    (It will turn transparent, and you are ready to select the second component)
  5. Hover the mouse over the circle in your Layout Sketch.
    A similar Joint Origin will appear in the centre.
  6. Click on the circle, and the LED ring should jump up and align with the circle.
  7. Check that the alignment is correct –
    Click on the ‘Flip‘ icon to toggle the direction of the LED ring.
    Make sure the LEDs are facing toward the FRONT of the design.
  8. When happy with the Joint alignment, click ‘OK‘.

We’ve imported and connected the LED Ring to our design.
1 component done. 3 to go!


Step 4: Insert Battery Holder

  1. In the Data Panel, right-click (or two-finger click) on the Battery Holder component.
    Select ‘Insert into Current Design’.
    (This may take 5-15 seconds, be patient and wait for it to appear in the canvas…)
  2. When the component appears, click on ‘OK’ in the dialog:

The Battery Box is inserted, now to connect it.


Step 5: Joint Battery Holder

Like before, we’ll create a Joint to connect the Battery Holder to the design.
(Watch the videos below, or review Step 3 if you get confused)

  1. Select the ‘Joint’ tool.
  2. Hover the mouse over the large face of the battery holder until you see the Joint Origin in the middle, then click on it.
  3. Hover the mouse over the centre point of the sketch’s large rectangle until you see a Joint Origin aligned flat with the rectangle, then click on it.
    The Battery Box jumps into place, but it’s aligned incorrectly!
  4. In the Joint dialog, change the alignment angle to 90 deg.
    If the Battery Box is on the wrong side of the sketch, click on the Flip icon.
    When you’re happy with the Joint alignment, click OK.

2 components done, 2 to go…


Step 6: Insert Digispark

  1. In the Data Panel, right-click (or two-finger click) on the Digispark component.
    Select ‘Insert into Current Design’.
    (This may take 5-15 seconds, be patient and wait for it to appear in the canvas…)
  2. When the component appears, click on ‘OK’ in the dialog:
  3. It’s a bit hard to see the Digispark – the Battery Box is in the way!
    Click on the visibility icon  next to the Battery Box to hide it.

Step 7: Joint Digispark

Like before, we’ll create a Joint to connect the Digispark to the design.
(Watch the videos below, or review Step 3 if you get confused)

  1. Select the ‘Joint’ tool.
  2. Hover the mouse over the back face of the battery holder until you see the Joint Origin in the middle, then click on it.
    (Pivot the view around if you cannot see it)
  3. Hover the mouse over the centre point of the sketch’s medium rectangle until you see a Joint Origin aligned flat with the rectangle, then click on it.
    (You can see that at first the Digispark is not aligned properly either)
  4. In the Joint dialog, change the alignment angle to 90 deg.
    If the Digispark is on the wrong side of the sketch, click on the Flip icon.
    When you’re happy with the Joint alignment, click OK.
    NOTE: It looks like the small parts of the Digispark get left behind. Don’t worry! They’ll fly to the right place when you click OK.

One left…


Step 8: Insert Tact Switch

  1. In the Data Panel, right-click (or two-finger click) on the Tact Switch component.
    Select ‘Insert into Current Design’.
    (This may take 5-15 seconds, be patient and wait for it to appear in the canvas…)
  2. When the component appears, click on ‘OK’ in the dialog:

     


Step 9: Joint Tact Switch

Like before, we’ll create a Joint to connect the Tact Switch to the design.
(Watch the videos below, or review Step 3 if you get confused)

  1. Hide the Battery Box if it is in the way.
    Click on the visibility icon  next to the Battery Box to hide it.
  2. Select the ‘Joint’ tool.
  3. Hover the mouse over the red area of the switch until you see the Joint Origin at it’s base, then click on it.
    (Pivot the view around if you cannot see it)
  4. Hover the mouse over the centre point of the sketch’s small square until you see a Joint Origin aligned flat to it, then click on it.
  5. In the Joint dialog, change the alignment angle to 90 deg.
    Click the ‘Flip’ icon if you want to adjust the Joint direction, then click OK.

     

All the components are in place! Good work.


Step 10: Finishing Up

  1. Show the Battery Box with  if it’s still hidden, then go to the ‘Home’ view.

    Save your work by clicking on the  icon.
    All done!


Conclusion:

What you’ve made forms a stable foundation for the rest of your design.

Now that you can see the components in their initial location,
What do you think your Selfie Ring Light will look like?
Get some paper and try sketching your ideas – at least a Front View and a Side View.

Do you want to change the component layout? Move the components around? Change their alignment, their angles?
If you want to experiment, you can select ‘Save As’ from the drop-down menu and make copies of the design.
