Nixie Tubes are electronic devices that were commonly used in the past to display numeric and alphanumeric characters. These devices are made of a sealed glass tube that is filled with a low-pressure gas, typically neon or a mixture of neon and other gases. The tube contains several cathodes, typically shaped like numbers or letters, and a set of anodes arranged around them. When a voltage is applied to an anode, it ionizes the gas around the cathode, creating a glowing plasma that is visible through the glass envelope. Nixie Tubes were first introduced in the 1950s and were widely used in electronic equipment such as calculators, counters, and clocks. They were popular because they provided a bright, easy-to-read display that was visible in low-light conditions. However, the technology was eventually replaced by more advanced display technologies such as LED and LCD displays, which were cheaper and more energy-efficient. Despite being largely obsolete, Nixie Tubes have gained a cult following among electronics enthusiasts and hobbyists who appreciate their retro aesthetic and unique display capabilities. They are often used in DIY projects, such as clocks and temperature displays, and are prized for their warm, orange glow and distinctive appearance. In recent years, there has been a resurgence of interest in Nixie Tubes, with some manufacturers producing new tubes and others developing modern versions of the technology. These new tubes often incorporate advanced features such as wireless connectivity and programmable displays, making them a popular choice for modern electronic projects.

Nixie Tubes are cold cathode devices made from a sealed glass tube filled with a low pressure gas. They were typically used in earlier electronic equipment such as computers and calculators to display numbers and symbols. Inside the tube there are one or more wires, which serve as the cathode and are numbered from 0 to 9. The anodes are a series of metal plates arranged in a circle around the cathode, which can be struck by electrons when a voltage is applied. When a voltage is applied to the anode, it triggers a glow inside the tube, which illuminates the numbers or symbols that make up the tube's display. Nixie tubes are still used in some projects today as a retro-style display.
