Perhaps you’ve also used them to generate a stable voltage drop because they have a pretty constant voltage across them when current is flowing, but that’s it. Diodes: the shortest Hackaday ...

The secret sauce is in component selection and tuning. Opengeiger uses the BPW34 diode because it is relatively common and has a large surface area, but also because it has a very low capacitance ...

also known as a Shockley Diode, is a crystal made of alternating layers of N- and P- type semiconductors. By putting in four layers, instead of the three used in transistors, the Shockley Diode ...

The semiconductor light-emitting diode, or LED, is a key component of today's technology. Modern households have numerous tiny glowing indicators — provided by LEDs — that are used for reading ...
