All the details anyone would ever want (and probably some that they don't) are on NewScrewdriver.com tagged with "Glow Flow". If a flat list in chronological order is not organized enough, here they are in a hierarchy of topics:

Initial bootstrapping

• Pixelblaze setup
• LED strip setup

Mechanical design of core

• Choosing a helix shape
• Calculating diameter and pitch of helix
• Putting results of that math in CAD
• Installing LED strip on 3D printed cylinder
• Installing Pixelblaze and placeholder power supply

Teach Pixelblaze about helix

• Pixel map for helix
• Test pattern (static): RGB-XYZ 3D octants
• Test pattern (animated): RGB-XYZ 3D sweep

Pixelblaze sensor board

• Examining sensor board
• Establish accelerometer axis
• Align accelerometer to pixel map axis
• Math required to utilize accelerometer values
• Performance optimizations to improve frame rate
• Incorporate other sensors on sensor board

LED Diffuser Investigation

• Paper Towel
• Featureless sheet
• Horizontal rib
• Diamonds with varied height and varied spacing

Tool less snap together construction

• Diffuser panels
• Core cylinder modification
• Diffuser panel support ribs required a few iterations
• Diffuser shell assembly complete

Power supply

• How much power might I need?
• How much power Glow Flow actually needs
• Batteries to feed Glow Flow
• Regulating power from batteries
• New regulators allow running LEDs at full power
