Prop for Downton Abbey larp


For the larp 1912 we wanted to have servant bells like in Downton Abbey.


Carl Nordblom made a nice looking construction for the bells using leaf springs.


An ESP8266 is listening on some bell topics for messages. If a message is received it will swing the corresponding servo with a bell hooked up.


To trigger the bells we built a box with a auto returning string to pull. The strings is hooked up to a micro switch witch triggers the reset pin on a ESP8266.
When the ESP8266 starts it sends a message on the corresponding MQTT topic to ring, then enter heavy sleep mode.
