IN-18 is a type of nixie tube, which is an electronic display device that was used in various electronic equipment from the mid-20th century. Nixie tubes are known for their distinctive retro appearance and are often used in vintage or retro-themed projects. Here's some information about the IN-18 nixie tube: Size and Appearance: The IN-18 nixie tube is one of the largest nixie tubes available. It typically stands around 70 millimeters (2.75 inches) tall, making it quite impressive to look at. The digits inside the tube are displayed in a distinctive glowing orange color, which is characteristic of nixie tubes. Digits: The IN-18 nixie tube can display the digits 0 through 9. Each digit has a unique arrangement of neon-filled segments, which light up to form the desired number. 116677.037021.046951 Gas Filling: Like all nixie tubes, the IN-18 contains a mixture of noble gases, typically neon and a small amount of argon, which emit the characteristic orange glow when an electrical current is applied. These gases are sealed inside the glass envelope. History: IN-18 nixie tubes were manufactured in the former Soviet Union (now Russia) during the 1970s and 1980s. They were used in a variety of applications, including scientific instruments, test equipment, and clock displays. Power Requirements: IN-18 nixie tubes require a high voltage (usually around 170-180 volts) to operate. This voltage is necessary to ionize the gas inside the tube and create the glow. Additionally, they require a lower control voltage for selecting and displaying digits. Driving IN-18 Tubes: To display numbers on an IN-18 nixie tube, you need to use specialized driver circuits that provide the high voltage and control signals. These tubes are often controlled using multiplexing techniques, where individual digits are lit up in quick succession to display the desired number. Availability: IN-18 nixie tubes are considered rare and somewhat challenging to find, especially in good working condition, due to their age and limited production. They are often sought after by collectors and hobbyists interested in vintage electronics and retro displays. Applications: While IN-18 nixie tubes are no longer commonly used in modern technology, they have found new life in various retro and DIY projects. Many hobbyists and enthusiasts use them to create unique clocks, temperature displays, and other decorative items with a vintage aesthetic. In summary, the IN-18 nixie tube is a large and visually striking nixie tube that was manufactured in the Soviet Union. It is known for its distinctive orange glow and has found renewed popularity in retro and DIY projects.
