hv neon lamp multivibrator – Circuit Schematic
hv neon lamp multivibrator
This unusual, simple multi-vibrator has only five components and uses neither vacuum tubes nor semiconductors but two miniature NE2 type neon lamps. This circui...
multivibrator astable – Circuit Schematic
multivibrator astable
The astable multivibrator is a unique form of the relaxation oscillator in which the in-phase feedback is provided by a separate transistor. The first multivibr...
Crystal audio oscillator circuit – Circuit Schematic
Crystal audio oscillator circuit
Generating variable audio frequencies with crystal precision is not often done because it isn`t easy to make. Low frequency quartz crystals are difficult to fin...
vackar vfo oscillator – Circuit Schematic
vackar vfo oscillator
It is probably the most stable VFO oscillator known. Vackar configuration is rarely used because of known reason. (The NIH, not-invented-here syndrome). The fre...
