Hi guys, how are you doing today?
Well, today’s interesting item is a metal alarm clock from the 1800s that uses modern hardware and obtains time from the internet.
The goal was to create a desk clock that resembles the traditional metal alarm clocks that have been around for more than 200 years.
It has the same design as a traditional metal alarm clock and even has bells with a handle and a stand.
The custom ESP12F-powered circuit at the center of this project shows the time obtained by the ESP12F when it connects to the internet using an NTP client. It also contains an SSD1306 OLED display and a few other necessary components.
It has a 3.7V Li-ion battery inside, which is coupled with a power management module to increase 3.7V to 5V so that the Clock circuit may be powered.
This Instructables is about the built process of this clock, so let’s get started!

Following were the materials used in this built-

- ESP8266 12F module
- Custom PCB
- 10K Resistors
- AMS1117 Voltage Regulator 3.3V
- 1uF Capacitor 1206
- 10uF Capacitor 1206
- Header Pin CON4
- SSD1306 OLED Display
- 3D Parts
- Nuts and bolts M3
- M4 Threaded inserts
- M4 Bolts”
