# 1. Characterizing the Lasercutter
# Characterizing the Lasercutter
In this week's group assignment, we were asked to characterize a laser cutter's focus, power, speed, rate, kerf, and joint clearance. We found these values on our lab's Epilog Fusion Pro 48 laser cutter.

# 2. Characterize the PCB design process
# Characterize the PCB design process
In this week's group assignment, we were asked to characterize the design rules for our lab's PCB production process: document feeds, speeds, plunge rate, depth of cut (traces and outline), and tooling. We found these values on one of our lab's [Bantam PCB Milling Machines](https://www.bantamtools.com/pcb-milling-machine).

# Design rules for 3D-printing
This week, we were tasked with testing the design rules for the 3D printers we will use. We completed these tests on our Ender 3 3D printers we all build to take home during our [Computer-Aided Design](http://fabacademy.org/2021/labs/charlotte/students/theodore-warner/assignments/week02/) week.

# 4. Oscilloscope and Multimeter Observations
# Oscilloscope and Multimeter Observations
This week, our group assignment is to use the test equipment in our lab to observe the operation of a microcontroller circuit board. We will use our lab's [Siglent SDS1202X-E](https://siglentna.com/product/sds1202x-e/) oscilloscope as well as digital multimeters.

# 5. Characterize the CNC Machine
# Characterize the CNC Machine
This week's group assignment is to complete the safety training for this extremely powerful machine and to characterize the relevant concepts of runout, alignment, speeds, feeds, materials, and toolpaths. These are all very important to take into a account since all of these will affect the quality of the product. We found these values on our lab's [ShopBot Desktop MAX](https://www.shopbottools.com/products/max).

# 6. Embedded Programming Architecture Types
# Embedded Programming Architecture Types
This week's assignment was to learn about and analyze different workflows for diferent types of architectures. As we had only programmed microcontrollers with variants of C thus far in Fab Academy, we decided to configure and program an LED to blink on a Raspberry Pi 4 and a Raspberry Pi Pico in order to investigate the programming and uploading process using different form factor boards and a different language from what we are used to.

# 8. Input Probing
# Input Probing
This week for group work we needed to probe an analog and digital input device using an oscilloscope. For our analog input we chose to use a potentiate. We wired everything up and then intercepted the signal wire with the probe. Once we had everything wired, we started testing, During our testing, we weren't able to adjust the axis to get a smooth curve but were able to see that the value was increasing and decreasing as we adjusted the position.
