Introduction: 7219 Tube Clock
This is my first instructable. I got my inspiration for building this clock from
https://nixieclocks.shop/product/energy-pillar-iv....
I liked the design of the clock and thought that VFD tube is difficult to find so I took 7219 seven segment 8 digit module available readily for the project . It is just a laser cut design similar to this clock. It is not VFD tube clock, however it looks similar to this.
Step 1: Materials
1. Arudino nano x1
2. DS1307 x1
3. Max 7219 8 digit seven segment display module x1
4. Four button keyboard
5. Zero board x1 for buttons
6. DC Socket x1
7. 4XStuds 3 mm dia, 240 mm length
8. Laser cut Clock Parts
9. 5V Adapter 10. Glue
Step 2: Connection Details (Circuit)
Pin mapping of 7219 module with Arudino Nano
7219 Module pin -> Arudino Nano pin
5V VCC -> 5V Pin Of Nano
Ground ->GND PIN
DIN -> D11
CS -> D10
CLK -> D13
Pin Mapping for Ds1307 Clock Module
1307 module -> Arudino Nano pin
Vcc -> 5V
GND -> GND
SDA -> A4
SCL -> A5
Buttons are connected On Pin No. A0,A1,A2,A3 of arudino

Step 5: Assembling
Assembling laser cut parts is not difficult i am giving here sufficient photographs to help
Assemble both side pieces as shown in pic Now insert stud from one side and cover the stud in between with circular lasercut washers.and assemble all parts
