Precision Lf Oscillator Circuit
Using Rl, R7, and D1 to preset CI to one third of the supply voltage. This circuit avoids a longer first cycle period than subsequent cycles.
The circuit described involves the use of resistors Rl and R7 along with diode D1...
high voltage ac calibrator circuit
This is an application circuit for calibration known as a high voltage AC calibrator circuit. A key aspect of sine wave oscillator design is the stable control of amplitude. In this circuit, the amplitude is stabilized through servo control, which...
magnetic field therapy
Devices capable of disabling and destroying microorganisms, including viruses, bacteria, and fungi, utilize pulsed, intense magnetic fields. These devices are not futuristic concepts but are currently available and employed in the alternative health field. Various claims exist regarding their effectiveness,...
Ground-Fault Hall Sensor
No electrical contact exists between the circuit and the conductor. The 7474 flip-flop is triggered by the output from the Hall sensor, op amp, and Schmitt trigger. This triggering activates the optocoupler, turns on the triac, and trips the circuit...
AirBorn Electronics project
Embedded system design engineers create examples of their work from the 1990s era.
Embedded systems have evolved significantly since the 1990s, and the design work from that period reflects the technological limitations and innovations of the time. Engineers in this field...
Objects in Flux
The Open Source Automation project is a free automation software that operates on Windows and does not require programming for setup. It features a user-friendly graphical interface and includes unique functionalities that are not typically found in high-end security and...
Interpolating Scanner Circuit
This design is for an interpolating scanner, a circuit featuring multiple signal inputs, a control voltage input, and a signal output. The output selectively transitions between inputs, smoothly fading from one to the next as the control voltage increases. A...
Precision-full-wave-rectifier
This circuit provides accurate full-wave rectification. The output impedance is low for both input polarities, and the errors are small at all signal levels. It is important to note that the output will not sink heavy currents, except for a...
Precision calibration standard
An external power supply that provides a voltage higher than the maximum expected rating of the zener diodes to be tested is required. Potentiometer RV1 is adjusted until the meter reading stabilizes. This reading represents the breakdown voltage of the...
