Focus Totem — Devlog #2

I changed the board from a rough cluster to a proper routed PCB now, and every error i had before is pretty much cleared. Both LED-chain labels were quietly landing on the exact same point, so I re-spaced them to each own their stub, and the dangling chain-end output got a proper no-connect flag instead of sitting there as a one-pin net. The bigger job was the footprints. I built accurate ones from scratch for the XIAO (7 pads a side, 2.54mm pitch, 0.6” rows) and the SK6812 MINI-E, added a footprint library so nothing looks like its floating, and switched the switches over to the correct stock footprints. After that it routed cleanly: 70 × 72mm, two-layer, ground pour both sides, M3 corner holes, and the XIAO’s USB sat on the bottom edge ready for the case cut-out. The ratsnest is completely gone. On top of that the firmware’s now actually a timer instead of a stub. I added the set → run → pause → done plus the break presets. The encoder sets the minutes, the OLED shows FOCUS / BREAK / DONE / SET with a live mm:ss countdown, and the two LEDs do the thing I wanted from the start, amber while idle, green while running, red in the final minute, then flashing when you’re done. It’s the first time it’s felt like the actual desk totem I pictured rather than a wiring diagram.
