Tubes to Transistor in Electronics Circuits - How it works. ... more.

One of the evergreens of classical mechanics demonstrations is the behavior that can be elicited from a gyroscope. The word 'gyroscope' was coined by the french physicist Foucault. Foucault was active in optics, in the manufacturing and testing of lenses and mirrors, in the chemistry of photography, and he did research in electromagnetism. Today he is mainly known for the pendulum setup that is... more.

Transistors are extremely useful devices, this video attempts to show you how the internal workings of the bipolar junction transistor actually work. ... more.

This time Dave shows you how to drag solder and tack & reflow SMD components, and in particular 0.5mm fine pitch IC's. Including solder paste and hot air. ... more.

Schematics are the functional diagram of electronic circuits. With so many designs available on the web, understanding how to read schematics can unlock a world of possibilities for the electronics maker. In fact, if you can read a schematic, you can build a circuit before even understanding how it works! ... more.

Just how far out is that +/-1% metal film resistor you are using? Is it just random? Does it follow the classic bell shaped Gaussian response? What are the odds of getting one that's spot on, or right out at the limits? ... more.
