VFD Night Light with Attiny84

VFD Night Light DIY Project. Developed and written by Frasier Chew. Vacuum Fluorescent Displays (VFDs) have been around for over 6 decades. Although its heyday has passed in favour of other newer display technologies like the LCD, they are still being used today because of their robustness. VFDs are able to operate under a wide […]

Phase Velocity: Waves and Signals

Phase velocity typically denotes the speed with which a sinusoidal wave or tone moves in the medium in which it propagates. The term is coined because the velocity at which the tone moves is equivalent to the speed at which any one of its phases moves, whether it is a phase that produces a zero, […]

Create GIF Files in Octave and Matlab

Nowadays, in any technical work of a certain level, it is common to program and simulate codes in mathematical simulators such as Matlab, or its free “equivalent” Octave. Typically the results of these simulations can be part of documents, presentations and meetings. On many occasions we could benefit from motion graphics to better visualize, explain […]
