An electronic color code or electronic colour code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring.
The 12-hour clock is a time convention in which the 24 hours of the day are divided into two periods: a.m. and p.m.. Each period consists of 12 hours numbered: 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11. The 12-hour clock has been developed since the second millennium BC and reached its modern form in the 16th century.
Napier's bones is a manually-operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers.

It was printed in Edinburgh and dedicated to his patron Alexander Seton.
Kryptos is a distributed sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) headquarters, the George Bush Center for Intelligence in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the four encrypted messages it bears. Of these four messages, the first three have been solved, while the fourth message remains one of the most famous unsolved codes in the world. The sculpture continues to be of interest to cryptanalysts, both amateur and professional, who are attempting to decipher the fourth passage. The artist has so far given four clues to this passage.
Herbert James Sanborn, Jr. is an American sculptor. He is best known for creating the encrypted Kryptos sculpture at CIA headquarters in Langley, Virginia.
A binary clock is a clock that displays the time of day in a binary format. Originally, such clocks showed each decimal digit of sexagesimal time as a binary value, but presently binary clocks also exist which display hours, minutes, and seconds as binary numbers. Most binary clocks are digital, although analog varieties exist. True binary clocks also exist, which indicate the time by successively halving the day, instead of using hours, minutes, or seconds. Similar clocks, based on Gray coded binary, also exist.

The 6526/8520 Complex Interface Adapter (CIA) was an integrated circuit made by MOS Technology. It served as an I/O port controller for the 6502 family of microprocessors, providing for parallel and serial I/O capabilities as well as timers and a Time-of-Day (TOD) clock. The device's most prominent use was in the Commodore 64 and Commodore 128(D), each of which included two CIA chips. The Commodore 1570 and Commodore 1571 floppy disk drives contained one CIA each. Furthermore, the Amiga home computers and the Commodore 1581 floppy disk drive employed a modified variant of the CIA circuit called 8520. 8520 is functionally equivalent to the 6526 except for the simplified TOD circuitry. Predecessor to CIA was PIA.

Lund astronomical clock, occasionally and at least since the 16th century referred to as Horologium mirabile Lundense, is a 15th-century astronomical clock in Lund Cathedral. Mentioned in written sources for the first time in 1442, it was probably made and installed sometime around 1423–1425, possibly by Nikolaus Lilienfeld. It is part of a group of related medieval astronomical clocks found in the area around the south Baltic Sea. In 1837 the clock was dismantled. Between 1909 and 1923, it was restored by the Danish clockmaker Julius Bertram-Larsen and the Swedish architect responsible for the upkeep of the cathedral, Theodor Wåhlin. From the old clock, the face of the clock as well as the mechanism, which was largely replaced during the 18th century, was salvaged and re-used. The casing, most parts of the calendar which occupies the lower part, and the middle section were made anew.
