devlog 1 - idk what im calling this

just finished the pcb for my hackpad. its a 3x3 macropad for shortcuts - app
launchers on the top row, screenshot/fullscreen/calculator in the middle,
copy/paste/undo on the bottom

specs

• 9 mx switches on a 3x3 diode matrix (row2col)
• 9 sk6812mini-e rgb leds, reverse mounted so they sit in slots in the board and
  shine up through the switches. per key lighting
• ec11 rotary encoder for volume
• 0.91” 128x32 oled
• seeed xiao rp2040
• 96.38 x 90.90mm, 2 layers, chamfered corners, 4x m3 mounting holes for a
  sandwich case

firmware

also got the qmk firmware compiling. the oled shows a clock and a spinning globe
made from real natural earth coastline data. 24 frames, projected the land
polygons onto a tilted sphere so those are actual continents at 32x32 pixels

next up

the case in fusion 360
