Nixie Clock oxygen

開發緣起，在 COSCUP 2019 聽了 @yodalee 大大的演講後再加上同學的鼓勵，又覺得它超帥的啊啊啊啊啊，決定自己也來做一套，專案從大大那邊 Fork 過來。

TODO

• 將電路中 IN14 換成 IN12-A

• 打算直接使用 K155ID1

• 確認兩種不同nixie tube data sheet 腳位差異

• 硬體

  • 高壓電模組
  • 降壓模組
  • 中央控制模組
  • RTC 模組
  • Nixie tube 控制模組

• 韌體

  • RTC校正
  • 數字顯示
  • Arduino 與 ATmega328 腳位定義

Usage

1. Order the hardware board using the Gerber file.
2. Buy materials according to BOM file.
3. The software, please copy pin<version>.h to pin.h inside each directory.

CAUTION

• The BOM table may have some difference that I did not notice, please check before you order.
• v1.02 only draw on easyEDA, it does not get fabricated and tested. It might have design problem and cannot work normally. Use it carefully.
