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:
- 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
- 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
- Succeeded using another DXF converter
Total time spent: 1h
June 19th: Worked on CAD
- Created the general shape of the CAD, including the cavity
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
- 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
- Tried extruding the entire thing but didn't quite work
- In the end, it worked by using
add
in the extrude instead ofnew
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
- 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
