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
(Assignment)
AVR AVR-1
3216		 UPDI USB-Serial board & Serial-UPDI board
ARM SAMD11C JTAG/SWD FreeDAP board
Xtensa ESP8266
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

  • 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

Material

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

Todo

Ref. FA2021

  • 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

  • Power, Speed, Rate
    • Find the best parameter from this experiment

Download: svg , cdr

  • Kerf
    • 10 sticks (11 cuts)
    • 1/2 + 9 + 1/2 = 10 Kerf Download: f3d

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
