Phage Pager

Light controller and paging badge, for phage campers only. Please note quantities are limited: only 50 pieces with radio, and up to 80 pieces without radio can be made. Sign-up sheet is pending first working prototype.

Features this year include:

  • Greatly reduced cost
    • Version with radio, accelerometer, microphone, and LED driver: $20
    • Version with just LED driver: $10

All versions include:

  • STM32F microcontroller
    • drive hundreds of LEDs
    • multiple strip driver ports
    • Possible to daisy chain to create matrix display (requires you to code up comms bus)
    • Program STM32F via serial port using FTDI serial cable (same as used on Arduino)
    • 4x UI butons to make it easier to change patterns and adjust brightness
  • Simple form factor
    • USB-A plug can plug directly into battery pack with no cable
    • USB-A plug is more robust and can handle more abuse than microUSB
    • USB-A plug is for power only. It does not show up as a USB device.
    • 68mm x 25mm in-line form factor

Radio version includes:

  • 900 MHz radio pager, compatible with 2013 badge
    • SMA coax whip antenna, 1/4 wave 2" antenna provided
    • Estimate 2-4x range of last year's badge
    • Better performance in a crowd of people
  • Single built-in diagnostic LED to indicate when being paged
    • Typically combined with WS2812 belt lights for better effect
    • Features open-drain driver which can power, for example, a laser mounted upward so it's easy to find people in a crowd
  • Accelerometer
    • Disable laser driver output when user is not standing upright
    • 800Hz update rate, can work as a pedometer if someone would write software for it
  • Silicon MEMS microphone (should handle dust better than electret cartridge mic)
