## Preparation for next week
> **Electronics Production**  
> *group assignment:*  
>   characterize the design rules for your in-house PCB production process  
>   extra credit: send a PCB out to a board house  
>   
> *individual assignment:*  
>   make an in-circuit programmer that includes a microcontroller:  
>      extra credit: customize the design  
>      mill and stuff the PCB  
>      test it to verify that it works  
>      extra credit: try other PCB processes  

### MCU

Family|MCU              |Interface |in-circuit programmer</br>(Assignment)
--    |---              |--        |---
AVR   |AVR-1</br>3216   |UPDI      |USB-Serial board & Serial-UPDI board
ARM   |SAMD11C          |JTAG/SWD  |FreeDAP board
Xtensa|ESP8266</br>ESP32|Serial    |USB-Serial board

!!! Attention
    FA2022 Trend  
    SAMD11C -> USB-Serial board  
    To Programm SAMD11C, need another DAP programmer board  
    (Not FTDI chip)  

### SAMD11C programming environment

  - Use any PC and Commercial DAP to program your SAMD11C board
  - Use Raspberry Pi3 (Raspberry Pi OS) as OpenOCD to program SAMD11C  
  - Use Raspberry Pi4 (Ubuntu) and Seeeduino Xiao as DAPLink to program SAMD11C  

### Preparation
  - **microUSB (16G,32G)**
  - Raspberry Pi3 /Raspberry Pi4
  - Seeeduino Xiao

## Group Assignment
>   characterize your lasercutter's focus, power, speed, rate,   
>     kerf, joint clearance and types

### Have you answered these questions?

[Assessment](https://fabacademy.org/2022/nueval/computer-controlled_cutting.html)

- linked to the group assignment page  
- Explained how you parametrically designed your files  
- Documented how you made your press-fit kit  
- Documented how you made your vinyl cutting  
- Included your original design files  
- Included your hero shots  

### Hero shots

well-taken photos, not snap shots

### Laser cutter
Universal [vls2.3](https://www.ulsinc.com/products/platforms/vls2-30dt)

- 30W CO2
- [manual](https://drive.google.com/file/d/0B9LkpMvsCJ3LN1JCNmJCUVZYNzQ/view?resourcekey=0-XEHkRxNO19cL2TE_kflW2g)

### Material
- card board
    - A3 or 300x450mm
    - about 3mm thickness (need to be measured)

### Todo
Ref. [FA2021](https://fabacademy.org/2021/labs/kannai/students/natsuka-kamei/week3.html#group)

- Focus
    - Lens: 2.0 inch (2.54 x2 mm)
    - Z Axis resolution 0.1mm
    - Defocus +3.0, +2.5, +2.0 +1.5, +1.0, +0.5, 0, -0.5, -1.0

## Individual Assignment

>  cut something on the vinylcutter  
>  
>  design, lasercut, and document a parametric construction kit,  
>  accounting for the lasercutter kerf,  
>  which can be assembled in multiple ways,  
>  and for extra credit include elements that aren't flat
