Release 2.5 Is available

Main updates for release 2.5:

  • Multicasting. Sent timing via (wireless) LAN to multiple other PC's/RaspberryPI's.
    - So no long video cables needed anymore.
    - Easy support for alternating matches since it is easy to project a different clock on left and right side.
    -In combination with Raspberry PI systems a cost saving solution.
  • Color Schemes
  • Improved remote controll for ppt-laserpointer Serial/USB equipment and GPIO (Raspberry PI) by configurable funtions for input buttons. In near future an Androids app available for controlling the timer.


Download test version of release 2.5:


Software is available for free. We are still doing some changes in the code. Mainly to add functionality, but also to improve usability.

Any suggestions to improve the software let us know.




One Main PC. Ensure "Broadcast time stamps over LAN network" is enabled.




All other PC's. Ensure "Follow" mode is enabled.



Be sure the client PC's use the same broadcast adress and port number as the main PC.
