    # 4. Electronics production
    This week I worked on defining my final project idea and started to getting used to the documentation process.
    ## nueval
    - [nueval](https://nueval.fabacademy.org/#/login)
    - Login with fablabs.io
    - Student's checklist -> **Send Message to Instructor(in English)** -> Local evaluation
    - Progress -> Completed (Assignment done)
    - (Local eval) Completed x 2 -> Request to Global Evaluation
    - Global Evaluator will be assigned -> Global Evaluation starts
    - (Global eval) Completed all + Final Presentation -> Graduate!

    ## Preparation for next week
    > **3D Scanning and Printing**
    > *group assignment:*
    > - test the design rules for your 3D printer(s)
    >
    > *individual assignment:*
    > - design and 3D print an object (small, few cm3, limited by printer time)
    > that could not be made subtractively
    > - 3D scan an object (and optionally print it)
    ### FAQ Define cannot be easily made subtractively
    > Answer: Your model has undercuts), overhangs, nested parts, meshes etc.
    Ref. [assesment](https://fabacademy.org/2022/nueval/3d_scanning_and_printing.html)
    ### Preparation
    - idea or model for 3D printing
    - idea or find object for 3D scan

    ## Code Example
    - http://fabmodules.org/ -> 404
    - [Mods](https://mods.cba.mit.edu/)
    Use the three backticks to separate code.
    ```
    // the setup function runs once when you press reset or power the board
    void setup() {
    // initialize digital pin LED_BUILTIN as an output.
    pinMode(LED_BUILTIN, OUTPUT);
    }
    ### ToDo
    - Set up milling environment
    - [Tips: Genmitsu PROVerXL 4030](./tips/genmitsu_prover_xl_setup.md)
    // the loop function runs over and over again forever
    void loop() {
    digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
    delay(1000); // wait for a second
    digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
    delay(1000); // wait for a second
    }
