When looking across the discrete components in your electronic ... together using a few diodes rather than another 74 series chip. A diode mixer or ring modulator (corrected circuit, thanks ...

If the signal is amplified, it is active. A special type of component is the integrated circuit (IC) where large numbers of transistors, resistors, diodes, and other electronic components are packaged ...

you can make printed circuit boards with an Ultimaker. [Geggo] had the idea of attaching a blue laser diode to his Ultimaker to burn a few traces into presensitized copper board. With a 3D printed ...
