v0.4 (Mechanics - gearless)

• Eliminates all gears - the spool is now directly driven by the motor for less mechanical complexity
• Adds an optional connector piece for loosely attaching adjacent modules to each other, and a 4mm hole on the top and bottom to allow modules to be attached to an external structure if desired
• This is the design seen in https://www.youtube.com/watch?v=vq4o_88kN8g (all 4 modules)

v0.3 (PCB + Mechanics)

• New controller design: Arduino-compatible shield, chainable for up to 12 modules controlled from a single Arduino Uno
• Eliminated 5mm rod/axle for spool; uses M4 bolts instead, for easier parts sourcing
• This is the design seen in https://www.youtube.com/watch?v=04el3LYiOaI (the center module; the outer modules are v0.2 modules) and https://imgur.com/a/0VAMZ

v0.2 (PCB)

• v0.2 pcb design - USB controller and sensor board
• This is the design seen in https://www.youtube.com/watch?v=1Df4Lg8UIck

v0.2 (Mechanics)

• v0.2 mechanical designs - laser-cut enclosure and gears
• This is the design seen in https://www.youtube.com/watch?v=bslkflVv-Hw and https://www.youtube.com/watch?v=1Df4Lg8UIck
• Fixes front window size/location, fixes enclosure tabs, adds flap backstop
• Known issues: Spool gear missing alignment hole; must be drilled manually (See #9)
