BEWARE TRAVELLER! This thing is so unnecessarily overengeneered that it can make a crocodile cry (theoretically). You tought a simple four digit clock wouldn't need wifi connection, or a count up timer, or maybe a humidity sensor?! YOU WERE WRONG! I added many things to this badboy, because... well... I COULD!
Completed clock, without casing
So, let me just put that marketing aside. This is my wifi-enabled nixie clock that I proudly present to you. I'm a beginner with electronics, but a bit better around code, so don't you dare judge me on my technical decisions. I wanted to make the most out of my design, only because of the sake of my own fulfillment.
Finalized protoboard circuit. Web control panel in background.
Main aspects of the project:
- working four digit nixie clock display (as you probably guessed)
- wifi connection
- manual or automatic mode for time setting
- automatic time updates from the web - configurable NTP time server
- timezone offset can be set dinamically from the config page
- OOP code (YASSS!!! 'Duinos needs more sweet-sweet object-oriented love)
- webpage based control panel
- by using mdns the clock has it's own domain address in the local network
- Androids do not support mDNS so there is option for static ip in the config page
- timed AP mode (broadcasting his own network) for the essential setups
- count up/down timers
- humidity and temperature values
- there is an air pressure sensor inside too, so maybe... (later varsion)
- automatic slot-machine effect to protect against cathode poisoning
- automatic tube turn off based on the presence of specific device MAC on the network (delayed to later version because of technical difficulties)
- leading zeros turn off
- display flashing feature
- modular design for easier repairs/modifications
- code design focuses on the longevity of the electronic parts (tries to avoid unnecessary actions)
There are things that did not made into 1.0, but I wanted to release it anyway.
Current firmware version: 1.0
Compatible pcb version: 1.0
