Skating Lap Counter is a project to automate counting laps skated on a derby track.

Project Status

  • 2014-07-03: Almost finished the RX schematic, but realized I forgot the audio signaller and that the DC-DC chosen is buck-only and needs to be buck/boost.
  • 2014-07-01: More work on the RX, getting close to done the schematic side.
  • 2014-06-30: Worked on the design/BOM/schematic for the RX more.
  • 2014-06-29: Completed routing TX PCB and checklisted it. Started designing the RX.
  • 2014-06-28: Started putting idea together, designed transmitter BOM/schematic, started working on PCB layout. 5 airwires left.

Architecture

  • Small module that attaches to one skate
    • IR emitter, microcontroller, and battery
    • When switched on, transmits a code repeatedly
    • Rechargeable via USB
  • Base unit with an IR receiver and display
    • Shows how many times each skate module has passed by
    • USB rechargeable and USB data interface for possible future use
