+
+I have found that there is only so much you can do to prepare for a technical interview, at least in the short term. Of course, maintaining fundamentals is always helpful. When it comes to behavioral interviews, there is much more preparation work to be done. In behavioral interviews, the most important aspect is simply raw interview skills, and the best way to get good at interviewing is through practice. When I was preparing for interviews this Fall, I asked my Aunt, who conducts behavioral interviews as part of her job, if we could set up a mock interview, and she happily agreed. Importantly, at the end, I asked for feedback and took notes.
+
+In addition to being prepared for the act of interviewing, it is important to come in knowledgeable about the position you are interviewing for. For example, when I was interviewing for a job at SpaceX, I researched the different projects associated with that job. Fortunately, with SpaceX being a company in the public spotlight, there were multiple Wikipedia articles about the projects that proved to be valuable resources.
+
+When it actually came to the beavioral interviews, I was glad that I did my research, because it helped me answer questions like "why do you want to work here?" and "what skills do you think you can bring to this role?" with details more specific to the company and role.
+
+When it comes to technical interviews, however, it is important to take your time and carefully explain your thought process. Most of the time, as long as you have sound reasoning and show significant understanding, it does not matter if you get the exact correct answer.

+## Introduction
+The purpose of this project was to construct an enclosure for the previously protoboarded circuit. The circuit board has three LEDs aranged in a line, resembling a traffic light. Additionally, the protoboard has a 1x6 right angle pin header with 100 mil pitch at the base. These pins are to be connected to a breadboard. The purpose of the enclosure is to protect the electronics from the outside environment and give it a more "finished" look.
+
+## Requirements
+1. Enclosure must have two pieces
+2. Enclosure must achieve an IP20 rating
+3. LEDs and header pins must extend through case walls
+4. All screws must fasten to heat set inserts
+5. Two halves must mate mechanically
+
+## Procedure
+First, we created a low-resolution mockup of the protoboard, with its most prominent features present. This was done in ECAD with standard component libaries to ensure proper sizing. The board edges were also measured, and the final PCB was exported as a STEP file for use in MCAD. This model is seen in the figure below:
+
+![](stripboard.png)
+
+Next, the enclosure front was built up around the model with 25 mil gaps on all sides of the board except the edge with pins to add some wiggle room for the PCB. This shape was extruded vertically, both above and below the board to create the walls of the enclosure. Then the top face was added, using the protoboard model as a guide to cut holes for the LEDs to poke through. Finally, another body, the back panel, was added. This panel adds both a back to the enclosure, further protecting the electronics, and internal support for the PCB to restrict its motion inside the enclosure. Grooves and tabs were added to the front and back pieces respectively to allow them to slide together. The final model is seen in the figure below:
+
+![](exploded.png)
+
+Once the model was done, we exported the two bodies as STL files, and sliced them using Orca Slicer. The sliced gemetries are seen below:
+
+![](slicer.png)
+
+The two parts, fresh off the 3D printer are seen below:
+
+![](inside-iso.png)
+
+We assembeled the two halves in a final test fit. First, we tested the board fit, as seen below:
+
+![](board-inside.png)
+
+We had used a 20mil (~0.5mm) tolerance for the sliding fit [@All3DP]. The final fit was loose, but still acceptable. The fully assembled case with board inside is seen below:
+
+![](front-iso.png)
+
+Plugging it in, we can confim that the circuitry still works, and the pins are able to plug fully into the breadboard still, as seen below:
+
+![](lit.png)
+
+## Reflection
+Initially, we planned for the top of the enclosure to slide with dovetail-like joints into the bottom half. That way, when the board slid in with the top, it would fall into a pocket, securing the enclosure together. Unfortunately, this design made the pins less accessable, since the board had to be surrounded on all four edges. Fortunately, this was easily remidied, since the design could be easily modified. Speaking of ease of modification, using realtive measurements proved to be highly valuable. Going back and making changes was very simple this way. Additionally, we learned that doing small test prints was very helpful for testing fit, to see if dimensions had to be made smaller or larger. Finally, we learned that using ECAD and MCAD tools together, to combine their strenths, is super useful. Using ECAD to make the PCB model with standard library parts was way faster than measuring all the dimensions of the parts on the board.

+The weapon system should be robust, simple, and predictable.
+
+### 1.2 Name three of the measures of weapon effectiveness.
+Weapon systems may be measured in terms of circular error probability ($\text{CEP}_\text{XX}$), probability of mission kill ($P_\text{MK}$), probability of guidance ($P_G$), and probability of hit, damage, or kill ($P_H$, $P_D$, $P_K$).
+
+### 1.3 Is the ENU coordinate system in invariant?
+No, because all three directions (East, North, and up) are dependent on where on the surface you are.
+
+### 1.4 Assume only one illuminator and one launcher in the combat system, what two limitations of the combat system determine the depth of fire?
+With only one illuminator, only one semi-active missle can be supported at a time. With only one launcher, the time between firings is limited by the the launchers minimum time between missile launches ($\Delta T_{L_\text{min}}$).
+
+### 1.5 What are the two main philosophies in weapon scheduling? How are they different?
+#### Quickdraw
+Shoot early and often to maximize the number of shot opportunities.
+
+#### Sharpshooter
+Maximize the performance of every shot by trading firing rate for shot quality.
+
+
+### 2.1 Delay between missile launches ($\Delta T_L$)
+$$\Delta T_L = T_H \left(1 + \frac{v_t}{v_m}\right)$$
+
+```python
+import numpy as np
+import matplotlib.pyplot as plt
+
+
+MIN_DELAY = 5
+T_HOMING = 8
+V_MISSILE = 700
+
+
+def launch_delay(t_homing, v_missile, v_target):
+    return t_homing*(1 + v_target/v_missile)
+
+
+def main():
+    # Range of target speeds from 0 to 1200 (inclusive)
+    v_target = np.arange(1200+1)
+
+    # Delta T_L for each target speed
+    delays = launch_delay(T_HOMING, V_MISSILE, v_target)
+
+    plt.plot(v_target, delays, label=r"$\Delta T_L$")
+    plt.hlines(0, v_target[-1], MIN_DELAY,
+	      label=r"$\Delta T_{L_\text{min}}$", color='r')
+    plt.legend()
+    plt.savefig("launch-delay.png")
+    plt.show()
+```
+
+![](./launch-delay.png)
+
+Since the homing time is longer than the minimum time between missile launches, there is no such target speed where $\Delta T_{L_\text{Min}} = \Delta T_L$.
+
+### 2.2 Depth of Fire
+
+$$\text{TET} = \frac{\text{ROF} - R_\text{min}}{V_T}$$
+$$\text{TOF}_1 = \frac{\text{ROF}}{V_M + V_T}$$
+$$\text{DOF} = \frac{\text{TET} + \text{TOF}_1}{T_H} + 1$$
+
+
+```python
+import numpy as np
+import matplotlib.pyplot as plt
+
+TARGET_RANGE = 20E3
+MIN_RANGE = 2E3
+MIN_DELAY = 5
+T_HOMING = 8
+V_MISSILE = 700
+
+def depth_of_fire(target_range, min_range, t_homing, v_target, v_missile):
+    t_engagement = (target_range - min_range) / v_target
+    t_flight = target_range / (v_missile + v_target)
+    return (t_engagement + t_flight)/t_homing
+
+def main():
+    # Range of target speeds from 0 to 1200 (inclusive)
+    v_target = np.arange(1200+1)
+    
+    dof = depth_of_fire(TARGET_RANGE, MIN_RANGE, T_HOMING, v_target, V_MISSILE)
+    print("DOF for V_T=200:", depth_of_fire(TARGET_RANGE, \
+    	 MIN_RANGE, T_HOMING, 200, V_MISSILE))
+
+    plt.plot(v_target, dof, label="Depth of Fire")
+    plt.savefig("depth-of-fire.png")
+    plt.show()
+```

+DOF, where $V_T = 200$[m/s] is 14.0278 shots.
