A: Tutorial PCB Layout Progress
Milestones
Completed schematic, successfully imported components sourced online into Altium
Unit 4 completed from Altium Designer Tutorial Course
Learned how to define board shape from selected outline
Figure A1 - Schematic, Altium Designer Course
Figure A2 - PCB Layout, Altium Designer Course
B: ECE 118 Mechatronics Robot Re-Design from Proto-Board to PCB Layout
Milestones
Rev 1.0
Revised key circuits involved in track wire detection/beacon detection for game mechanics
Successfully sourced and imported components
Edited symbols to match actual symbol
Rev 2.0
Schematic: Revised schematic, switched to component parts for net connections instead of large overall custom component to ease schematic reading, clarify connections
PCB Layout: Shifted components on bottom right side up and towards the right, making the overall board shape less wide and longer for an overall cleaner look. Added graphics to silkscreen layer.
Notes
As I am in the process of moving, testing this circuit before sending out the PCB is not possible at the moment

C: USB-A Keychain Project
Project inspired by @sagecadencee on Instagram
Milestones
Rev 1.0
Created, revised custom footprint with partial assistance from Footprint Wizard tool to match USB-A pad specifications (Edge Connector ended up being the best match amongst the available pad presets, although the pads on the other side of the board were unnecessary)
Successfully connected custom footprint to custom symbol via creation of a component in Altium library
Completed PCB layout and all net connections
Imported graphics onto silkscreen layer
Successful exportation to Gerber file format & ordered from JLCPCB!
Soldered LED, resistor - lit up when connected to PC
Future Notes
widen keyring hole
solder on thicker USB port
flip components so that LED, resistor are on other side - also use SMD package

D: "Analog" Habit Tracker
Project inspired by Simone Giertz's 'Everyday Goal Calendar' (Yetch Studio here).
I'm getting back into the whole electronics world - it's been over a year now since my last microcontroller course. I have also wanted to play along with E-ink screens but in a smaller format (the larger screen still isn't quite what I'm looking for), so this project seemed like a nice way to combine it all. The PCB part of this will be in the LED matrix, I'll also be playing around with SMD soldering for the first time here.
And as always, this will be done with my brain and pencil and paper, no AI here!

Built preliminary circuit in Wokwi for Button-LED (Fig. D1)
Enabled shift register combination to turn LED on depending on given date (Fig D2)
