Yoda NFC Keychain

Created by [Kaitlyn Z] • Started on June 18, 2025

A Yoda-shaped NFC Keychain for me to hang and use

Total hours: 6.25 hr

June 18th: Worked on Design

  • Came up with two variations of the design: 2 versions of design
  • Decided to go with the one where it's shaped like Yoda
    • The ears may potentially come off (hopefully not) but it looks better than the one where the Yoda is enclosed in a box
  • Settled on Slytherin green for the shape, silver for the words (if there is no silver filament, then I will paint)
  • Found usable Yoda icon to be imported into Onshape Yoda icon
  • Used paint to color everything black so it would just be an outline in CAD
  • Converted into DXF but keep getting this error - took a while to solve it alt text
  • Succeeded using another DXF converter

Total time spent: 1h

June 19th: Worked on CAD

  • Created the general shape of the CAD, including the cavity alt text

Total time spent: 1h

June 20th: Worked on Letters

  • Added letters on front and back
  • Letters on the back keep looking misaligned - looking for ways to fix alt text
  • Realized it's probably aligned on the center of each letter, which is better than if I adjust it
  • Issue - circle on the back due to cavity alt text
    • Tried extruding the entire thing but didn't quite work
    • In the end, it worked by using add in the extrude instead of new

Total time spent: 2h

June 21st: Worked on Keychain Hole

  • Researched different Onshape methods to do a keychain hole
    • Sweep, Revolve, Loft, etc
  • Realized doing an extrude made the most sense - got that done

Total time spent: 0.5hr

June 26th: Found parts on EasyEDA

  • Added all the parts to my schematic on Easy EDA

Total time spent: 0.25hr

June 28th: Finished PCB

  • Finished schematic
  • Got an appropriate Yoda dxf, sized and exported from Onshape
  • Formatted and routed PCB
  • Tried out different designs and finishes alt text
  • Checked price on PCBWay and JLCPCB - with PCBA, it becomes >50 dollars so I cannot afford it with the easy project tier money

Total time spent: 1.5hr
