The Hacker Test was an old test of how much of a ‘hacker’ (as in ‘nerd’, not ‘cracker’) you are. Since it came out in 1990, almost all of the questions are obsolete. That makes it a really neat historical document of what people considered cool at the time. Hacker Test History https://github.com/hwayne/hacker-test-history →

A battery can be regarded as an ideal voltage source in series with an impedance, which is called internal resistance. When the battery works, the voltage output is lower than the open-circuit voltage (abbreviated as OCV). The difference is the voltage drop caused by the internal resistance. Internal resistance represents the battery’s limiting factor to →
There are applications where measurement of low resistances are needed. Measuring low resistance helps identify resistance elements that have increased above acceptable values. How you measure low resistances below one ohms? Most multimeters aren’t accurate below 1 ohm. Occasionally, you’ll need to measure electronic parts with very low resistances, such as wires, switches, current-sense resistors, →

I have Hung Chang HC-F100L multifunction counter that I bought few decades ago. I planned to do a teardown post of it some day, but someone else did it first. Korean Multifunction Counter Teardown https://hackaday.com/2024/07/07/korean-multifunction-counter-teardown/ [Thomas Scherrer] likes to tear down old test equipment, and often, we remember the devices he opens up or — →
A fiber-optic cable, also known as an optical-fiber cable, is a cable that is one or more optical fibers that are used to carry light. The optical fiber elements (typically made of glass) are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. →
