Would you like to have an external TapTempo device for your CQ ?
It would be DIY and free.
I would give all explanation but I sell nothing, so don’t ask.
Start project is based on ESP32 and it connect to the CQ via wifi.
Arduino IDE will be use to set the network ID and PSW.
Form factor will be a single footswitch, maybe a led or a OLED screen for status.
I am asking because I don’t need it , it is just for fun but if too few reply I will bury this project.
