This 2 channels audio mixer is based on the 2n3904 transistors which forms 2 pre-amplifiers. The first preamplifier of the audio mixer has a high gain and can be used for microphone input, and the ...

Previously I posted about how I seemed to be getting rather high CPU temps with my 3.0GHz P4, IC7-G, and a Zalman 7000CNPSAlCu. The temps were ~50 idle, ~64 load in MBM using the winbond 2 diode ...

The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

There are times when you make the effort to do a superlative job in the construction of an electronic project. You select the components carefully, design the perfect printed circuit board, and wait ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
