Fundamentals Friday

As the title says, kinda… Dave answers the age old question, do single take videos really work? No. No, they don’t. SPOILERS: Tutorial on turning two NPN transistors into a fast bidirectional zener impulse clamp. A comparison of the low level signal noise on 11 different oscilloscopes. Teardown of the …

Fundamentals Friday What is a Schmitt trigger and how does it work? What is hysteresis? And how do they fix two common problems in electronics, namely slow slew rate signals on CMOS digital chip inputs causing oscillation, and noise on comparator inputs. The issues are demonstrated first on the breadboard, …

Fundamentals Friday. A tutorial on Zener Diodes. Avalanche breakdown, zener breakdown, zener effect, knee voltage, power dissipation, differences from regular diodes, calculating dropper resistor value, voltage regulation, clipping, clamping, transient surge overvoltage protection, characteristic curve, forward and reverse characteristics.

In this Fundamental Friday Dave will blow your mind as he shows you how you can power a microcontroller *without* a power or ground pin! A potentially big trap for young and old players alike. Can you guess how it’s done before the secret is revealed? Forum HERE SPOILER: A …

Dave explains the fundamental DC circuit theorems of Mesh Analysis, Nodal Analysis, and the Superposition Theorem, and how they can be used to analyse circuits using Kirchhoff’s Voltage and Current Laws we learned in the previous video HERE The same circuit is solved using the 3 different methods. Will we …
