"Electronic Hardware Design"
summary
Step-by-step account of building a conference badge that looks like a bow tie with LEDs and a microphone, from part selection to finished board: uses KiCad for schematic and layout, exports Gerbers and a BOM, orders parts immediately during shortages, assembles via breadboard then through-hole prototypes then SMT with a reflow oven and solder paste stencil, and uses interactive HTML BOM for placement. Final design has 30 unique parts (92 total) versus a simpler version with 4 unique (26 total). CircuitPython bootloader and firmware take roughly four days to debug after fixes for a mislabeled mic net and a reversed power part; the bow tie works after those fixes.
