2 × Arduino Nano Controller for the clock (only 1 required for a single sided clock).
1 × ESP-01(S) ESP8266 WiFi module to make the connection to the network.
6 × IR tacho sensor IR optocoupler to detect the positions of the clock hands (only 3 required for a single sided clock).
6 × 28BYJ-48 5V + driver board Stepper motor 28BYJ-48 5V + ULN2003 driver board (only 3 required for a single sided clock).
1 × PVC pipe 25cm PVC pipe with an outer diameter of 25 cm, inner diameter of 24 cm, and a length of 10 cm (the length can be shortened to 8 cm for a single sided clock).
108 × Screw 2.9mm x 13mm
4 × Bolt M3 x 30mm and nuts
12 × Bolt M4 x 20/25mm and nuts
1 × Bolt M5 and nuts Bolt for suspending the clock.
1 × Matt plexi glass sheet 3mm thickness

1 × All kind of (little) components I mean: wires, tie wraps, heat shrink tube, glue, etc.
1 × Power supply 5V The maximum current of the power supply depends on what kind of clock you want to build. For an illuminated, double sided clock, the current must be >3.5A. In my case I used an old PC power supply.
