Hello folks! of cors, as every passioned gay in electronics, i wanna build my own nixie clock.
I have seen a lot of projects of these, of course. Here is a list of what I wanted to have in my watch:
- Time synchronization over the Internet.
- Powered by USB plug, of course - each of us has a USB charger, why buy more?
- Minimum buttons.
- Generation of all signals by one processor.
- Have the ability to replace my nixie tubes.
I broke my project into 2 boards:
On one is the processor, USB bridge - UART, a high voltage generator
On the one second, everything that is responsible for the indication is collected: Tubes, high-level keys, decoder chip.
