Digital Calipers DRO circuit | Next Electronics

RealView is a measurement application, which records and plots measured values from analogue hardware devices in real-time. Several curves can be plotted into a single diagram. Several diagrams can be arranged on one or more pages if necessary. Plot options...

Adjustment-free precision summing amplifier

This circuit generates continuous outputs that depend on multiple input variables. The circuit in question typically employs a combination of operational amplifiers (op-amps), resistors, and potentiometers to achieve its functionality. The outputs can be tailored based on the variations in...

Pots water alarm circuit

The flowers in pots require watering, as relying solely on the observation of moist soil surfaces can be unreliable. To address this issue, a flower watering indicator has been developed. This circuit includes a field effect transistor (VT1), a second...

Wire Break Sensor Alarm Circuit Schematic

The circuit of a loop sensor-based simple security alarm is described here. The sensor loop consists of a short length of thin enamelled copper wire. The loop sensor security alarm operates on the principle of detecting interruptions in the circuit formed...

Precision-threshold-detector

This circuit requires low noise, stable offset voltages, high open-loop gain, and high speed. These requirements are fulfilled by the HA5147. Standard variations of this circuit can be easily implemented using the HA-5147. For instance, hysteresis can be introduced by...

Instrumentation circuit

The mechanical chassis prototype, as illustrated in the accompanying image, was constructed using two materials: foam and aluminum. Foam was selected for its ease of manipulation, while aluminum was chosen for its excellent strength-to-weight ratio. The prototype features a rotary...

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-voltage-inverter

This circuit enables the inversion of a reference signal with an accuracy of 1 ppm. It features high input impedance and does not require any trimming. The described circuit is designed to invert a reference voltage signal while maintaining a high...

Add a sensor to a board and measure something with it

This week's plan is to build a device that warns of the potential for a knockdown, which is the process by which an over-canvassed ship is laid over on her beam-ends. The risk of sinking is high during this event,...
