Ever had trouble with cats that 💩 in your garden..? You wish there was a way to scare them off while doing this ..? You have an ESP8266 microcontroller laying around and might consider investing in a small siren and a realy ..?
Then this project might be for you ✌🏻
Youtube video https://youtu.be/687WEwndS4Y
Power on the device and search for the wifi network cat_alarm, then go to http://192.168.4.1 Within the interface you find
- Enabled - you can enable/disable the siren going of as you like (you may not want to wake up you neighbours)
- Between hours - you are able to configure within what hours you like this alarm to be active when motion sensor detects movement
- Honk button - there might be moment when you see that cat arrive then you can fire of the alarm when you like
- Debug - this will start the webrepl so you can remotely access the microcontroller
- Configure - when you like to configure which SSID this microcontroller should connect to, time when enabled and time it should "honk" etc
At the bottom you will get a list of the last motions that have been detected
Build the docker image of the master branch. The custom Dockerfile will add src as frozen and update the entrypoint
docker build -t catalarm-build . && docker create --name catalarm-build-container catalarm-build && docker cp catalarm-build-container:/micropython/ports/esp8266/build-GENERIC/firmware-combined.bin firmware-combined.bin && docker stop catalarm-build-container && docker rm catalarm-build-container && docker rmi catalarm-build To specify a particular version of micropython provide it through the build-arg. Otherwise the HEAD of the master branch will be used.
docker build -t catalarm-build --build-arg VERSION=v1.8.7 .The firmware can then be uploaded with the esptool
esptool.py --port ${SERIAL_PORT} --baud 115200 write_flash --verify --flash_size=detect 0 firmware-combined.binHere ${SERIAL_PORT} is the path to the serial device on which the board is connected.
