  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

  Version 1 Complete

  • Ideas for future versions
  • Documenting Glow Flow V1 online

• Twitter

  My WordPress blog is good for detailed writeups, but short video clips and some other bits of status end up on Twitter. 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:
