Initial bootstrapping
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
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
Version 1 Complete

I originally meant to have every Glow Flow tweet in the same Twitter thread, but I slipped up halfway through so there are now two separate threads.
The first one starting with Pixelblaze setup:

The second one starting with Glow Flow at Hackaday LA Meetup:
