Progress on archery timer

WarrenW

Hi All,

Looks like I am making progress on my archery timer.

I have flags se for the traffic light indicators and a pre-timer countdown prior to the start of the shoot. Then the main timer kicks in and changes the traffic lights and sounds buzzers etc.

Pulled apart the old lights that don't work anymore and found the supply regulated by a simple LM series regulator and the displays are driven by CD4511 BCD to seven segment drivers.

I will be connecting the radios next to confirm comms and then onto interfacing the transferred data into BCD to drive the displays.

    Sure will when I get home. Not much to see at this stage, just some arduino bits hanging together and a set of old ChronoTIR L'Arc lights (they look pretty cool).

    They are the Mk1 lights and the original owner lost the remote. Unfortunately you cannot buy the Mk1 remote.

     

    The Mk2 remotes do not work with it. I suspect they changed the data stream format.

     

    I inherited these and then used one of the original low power transceiver module form one of the displays to keep Archery NZ lights going.

     

    Given no remote and now one receiver gone, I figured I would build my own remote and interface an arduino into the existing circuit on the display.

     

    The display manufacturer can be found here..
