clockers -> snake_one transition leaves some pixels highlighted

Updated Guide 2023

You can run this off way less hardware. Record the data to an SD card and play it off a Teensy 4.1:

• Record output via Lightjams (4 universes; starting universe is 1)
• Output saved to hexasigns-4u-aligned-10-patterns.mp4
• Convert to output.bin via video2sdcard.py
• Use videosdcard.ino to play back file on Teensy
• Data channels 0 and 1 serve the top & bottom half of the first hexagon
• Data channels 2 and 3 serve the top & bottom half of the second hexagon

OLD GUIDE - Hardware Setup

Runs on Windows, Linux, and ARM (Raspberry Pi etc.).

• Get a Falcon F4V3 (firmware V2.0+)
• Default settings on it (DHCP)
• Cheap router ex. Netis WF2411
  • Set up wifi login if you need it
  • Rename the network to something cool
  • Assign an IP to F4V3 when it's connected. This IP is hardcoded in artnet.js
• Rextin WS2811 Pixels (12V 50pcs) x12 strands, or equivalent
• NES-350-12 power supply, or equivalent http://puu.sh/DGCpj/a2908da07a.jpg

How to Use

Check in index.js and make sure everything looks cool. Code to activate these:

• menu mode
• hardcoded single pattern
• @TODO rotate between em
• run npm i
• run npm start
