I've added a self-made circuit board to a commercially available Nixie tube kit and installed new, vintage East German Z570M Nixie tubes. The case is an original design, created from 3D data and outsourced. This is a genuine Nixie tube clock, not a panel-style one. Specifically, I used new Nixie tubes with no damage to the red film (these are rare). The set includes the clock itself, a power cable, and a manual summarizing the functions. - Type: Nixie tube clock (East German Z570M) - Color: Black - Material: Resin (3D printed, outsourced) - Power: USB-B cable (new. Opened once to confirm functionality) 【Functions】 ① Time setting ② 24h/12h display switching ③ Backlight LED switching ④ Night display OFF (sleep mode) ⑤ Time keeping (using CR1220 button battery) 【Caution】 ・The Nixie tubes use a high voltage of approximately 170V for illumination. ・Touching the circuit board or wiring while the power is ON can cause electric shock. ・Please refrain from purchasing if you have small children.
