Description
Bombo clock is a digital clock + alarm + timer + calendar + room temperature.
Simple and cheap to make.
By pressing the white button (set) the device starts a wifi access point that can be accessed and through a convenient web interface the device management is available: time, alarm and bomb timer.
(Independent device: no connection to your wifi).
Connect to ssid:BomboClock_xx, psw:012345678,
http://192.168.4.1 and configure it.
By pressing the red button (bomb) start a timer.
The clock has a battery, it can be recharged via USB port and/or left connected.
The microcontroller manages the battery charge.
The real time clock module (ds3231) also has a buffer battery:
if the microcontroller turns off, date and time are maintained by the ds3231 module.
It has (currently) two melodies (free and upgradeable firmware).
Optimized design for 3d printing.
Original and nice design, I hope you like my work.
