Fab Academy 2026 | Week 11 - Output devices Project - LM 393 Photosensitive light dependent resistor (LDR)

Week 08

Electronic production

Learning outcomes

  • Describe the process of tool-path generation, milling/laser engraving, stuffing, de-bugging and programming
  • Demonstrate correct workflows and identify areas for improvement if required
Week 3 cover

Assignment requirements

Group assignment

  • Characterize the design rules for your in-house PCB production process: document the settings for your machine
  • Document the workflow for sending a PCB to a boardhouse
  • Document your work to the group work page and reflect on your individual page what you learned

Individual assignment

  • Make and test a microcontroller development board that you designed

5) Final results

  • Linked to the group assignment page
  • Documented how you made the toolpath
  • Documented how you made (milled, stuffed, soldered) the board
  • Documented that your board is functional
  • Explained any problems and how you fixed them
  • Uploaded your source code
  • Included a 'hero shot' of your board
