EasyRaceLapTimer

EasyRaceLapTimer is a complete open source IR lap time tracker all-in-one solution for FPV racing quads.

What you get with EasyRaceLaptimer:

Features:

• host system for tracking the laps
• IR transponders (code & schematic files for building them) with a transmitting range of 2 to 4 meters
• 63 available transponder IDs when using the project transponders
• changing the ID via a push button on the transponder, no additional programming required (started with version 0.3.1 of the transponders)
• update transponders with new code (Arduino hardware needed)
• setup guide for building your Raspberry PI host station
• the host station is also a WiFi access point to change configs etc on the fly
• monitoring mode, you can watch the stats with your mobile phones
• add your own team logo to the monitoring mode
• detailed stats about pilots and races
• sound effects for various events in a race
• TCP/IP and serial connections support for receiving lap times and commands from other time tracking systems
• export race events to PDF
• standard practice/ time trial mode
• competition mode for racing events with time penalties (satellites needed)
• automatic restarting of a race session after a specified idle time
• and much more comming soon

Important notices

EasyRaceLapTimer works basicly with any IR transponder, as long as you provide code for interpreting the IR pulses. Just have a look at the ir_daemon tool.

Be sure to use the full size of your SD card on the Raspberry PI

sudo raspi-config

Important information

The documentation for the project can be found in the /docs directory.
There's also a huge RCGroups thread with lots of answered questions, images etc.
