Nixie Maestro is a fully-featured nixie clock kit, using a semi - assembled SMD board. The clock shows time and date on six vintage IN-12 Nixie Tubes, which are sourced from the former Soviet Union. Each tube has a RGB LED to illuminate it, which creates a beautiful spectrum of colour effects. Several case designs are available separately in the Cases section of our site.

This 20221 version, has some exciting features. Maestro works best in conjunction with our new XTERNA outdoor, wireless time and temperature transmitter module, to report accurate GPS time and also outdoor temperature with min / max function. Additional highlights of the new Maestro Clock are independent double dot colon neons
