FABx Event

  • July 2022 Butan -> Postposed
  • October 2022 Bali (with Fab City Summit)
  • 2023 Bhutan, 2024 Mexico, 2025 Czech Republic

Preparation for next week

Electronics Design
group assignment:
use the test equipment in your lab to observe the operation
of a microcontroller circuit board

individual assignment:
redraw an echo hello-world board,
add (at least) a button and LED (with current-limiting resistor)
check the design rules, make it, and test that it can communicate
extra credit: simulate its operation

Preparation

  • none

Group Assignment

  • test the design rules for your 3D printer(s)

Individual Assignment

3D print

design and 3D print an object (small, few cm3, limited by printer time)
that could not be made subtractively

Assessment

FAQ
Define cannot be easily made subtractively
Answer: Your model has undercuts, overhangs, nested parts, meshes etc.

undercuts_JP

  • include Fusion360’s .f3d file in your repo
  • STL in other site and embed in your page

Todo

  • Design in Fusion360
    • Export STL
  • Slice in slicer
    • STL -> g-code
  • 3D print in Ender-3 V2

3D Scan

3D scan an object (and optionally print it)

Todo

  • Scan a object by any App/ service
