I’ve been playing with various ciphers and encryption schemes, and needed a true random number generator to ensure secrecy. A Pseudo Random Number Generator uses a algorithm to produce a pseudo random number. If the algorithm can be determined, so
Looking for a way to detect dissolved oxygen levels? If you raise fish, this and a ph sensor are two important things to monitor (and of course, temperature), and an Arduino is the ideal platform to build upon. The Sensorex
Magnetic core memory was the most widely used form of digital computer memory from its birth in the early 1950s until the era of integrated-circuit memory began in the early 1970s. Aside from being extremely reliable, magnetic core memory is
I am just finishing up a project at work, which requires two water tanks to be maintained at 180F. Each tank has twin 1500 watt, 240vac heating elements, each controlled by a SSR (Solid State Relay). My Arduino Mega 2560
Why does trigonometry sound so scary? Often in the world of physics, and when the real world comes crashing into the lab, we need to use sine, cosine, and tangent in our calculations for having a way of relating the
