This nixie tube clock uses old GR10M/U tubes driven by exixe12 tube drivers and an Arduino with an LCD shield just for ease of setup and use. The buttons on the LCD shield can be used to set the date and time, and a DS3231 RTC module is used to keep track of time when the clock is turned off.<br><br>- Tubes: <a target="_blank" rel="noopener noreferrer" href="http://www.tube-tester.com/sites/nixie/dat_arch/GR10M.pdf">http://www.tube-tester.com/sites/nixie/dat_arch/GR10M.pdf</a><br>- Exixe12 Drivers: <a target="_blank" rel="noopener noreferrer" href="https://www.tindie.com/products/dekuNukem/exixe-miniture-nixie-tube-driver-modules/">https://www.tindie.com/products/dekuNukem/exixe-miniture-nixie-tube-driver-modules/</a><br>- Power Supply: <a target="_blank" rel="noopener noreferrer" href="https://www.ebay.com/itm/DC-5V-12V-to-180V-D">https://www.ebay.com/itm/DC-5V-12V-to-180V-D</a><br><br>The case design was originally tested with plywood and subsequently "upgraded" to walnut.
Nice build! The brass screws is a nice touch.
