 # FR-1 Trace lengths
 
 ## The experiment
-For the experiment, I used FR-1 that has a thickness of 35µm. On there I will mill 4 trace sizes (0.4 mm, 0,6 mm, 0,8 mm and 1 mm) and they all have the same length of 7.5 cm’s. The traces are seperated by 1 Cm.

 The capacitance is determined by the amount of copper is in the trace. So length, width and the thickness. When working with low frequency signals the capacitance is not super important.
 But when working with higher speed frequencies the capacitance can actually mess up the signal integrity.
 
+## Heat generation
+Heat within traces is generated by the current flowing through it. Not the wattage. A good example of the is train lines. These run on 230.000 volts on thin wires while being able to supply multiple trains. The higher the voltage the easier it is the transport a higher amount of wattage.

-the power. So I grabbed an old robot with 4 stepper motors attached but I could not get them to draw more than 30 watts. So that is why the maximum in this test is 30 watts. I also had a hard time finding a way to measure the temperature of the traces because we only had a heat gun here and the laser was not the place it was actually measuring. So 0,4 mm is not measured properly.

+I wanted to combine 2 random objects that interest me into one project. A drone and a jumbotron. So im gonna make a drone with multiple screens on it that could for example be used for traffic control or entertainment purposes. There is no real reason why I chose to make this beside it looking and sounding fun to design and build.
 
 ## What does the drone do?
 The drone needs to be able to fly for at least 20 minutes. It needs 2 screens on both side so it can display images or video. I wanna program the drone myself so I know how drones work and how they keep themselves upright.

 ### Designing the drone parametrically
 Designing parametrically is very hard because every constraint needs to be perfect. Otherwise when changing lengths the design will fold into itself like this.

-I've spend one day getting the constraints perfect for the sketch so it scales well with everything. And this is the result of that. When I change one parameter in the variable menu the entire body scales with it. This is the final result of my design. I've made the body myself and I've imported the components from grabcad. So I had more time for blender and Onshape and so I could visualize it better.

+## 3D printing
+I chose to fully 3D print my drone due to it's complex shape and time constraints. I still had a lot of work from university to do. We got encouraged to do compositing but that is super hard with the current design. However it would have been better since it is often lighter and more durable while being a lot more eco friendly. For 3D printing I am planning on using PLA because it has a lower carbon footprint than ABS and it releases less toxic fumes.

Unfortanetly I don't know how to connect them yet because the wires aren't labeled. 2 motors need to spin left and the other 2 right for stability.
