This video covers what inductance is, the units (henries), and how inductance increases when a core material is used.
Read MoreSo I recently got hold of some 2600F (no that is not a typo) ultracapacitors with an insanely low ESR of 0.7 milliohms, meaning they can discharge hundreds of amps even at low voltages. This video shows you some of the mayhem I got up to, and teaches some important capacitor formulas along the way. […]
Read MoreThis video shows you what a photoresistor is, where to get one, and how to use one to turn a transistor on and off. You can then use the circuit to build a laser tripwire, just like in the movies! When the laser beam gets broken, you can toggle whatever you want.
Read MoreOscillators are a fundamental building block in electronics. You use them as part of generating radio waves, controlling the speed of digital processors, generating synth music and more. But to start out with you might just want to try blinking an LED on and off. This video will show you some basic square wave and […]
Read MoreFunction generators are handy gadgets that generate waveforms. You can use them to generate sine waves, square waves, triangle waves etc of varying frequencies. The video explains why this can be useful, and shows you where you can buy a function generator for cheap. Incidentally, this kit was my first function generator.
