  • I too couldnt get much range from the IR on the puck

    In the end I decided not to use the puck for IR and went with an esp8266 wifi chip and external ir's, i get a few metres range with this­dyC/wifi-ir-blaster-af6bca

    You could perhaps try the same approach as the link and use a transistor and external ir leds with the puck
