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...
ProfiLab-Expert 4.0
The ProfiLab-Expert software allows you to develop your own digital or analogue measuring technology projects. It doesn't matter if you want to create analogue measurements or digital controls - you can realize it all. And for all this you don't...
Basics and implementation of capacitive proximity sensing
Capacitive proximity sensing has gained significant interest among audiences over the past year. At the end of this article, a list of related articles published at Planet Analog is provided for further reading. A simple proximity sensor is designed to...
simple capacitive touch sensor
Capacitive touch sensors operate based on the electrical capacitance associated with the human body. When a finger approaches the sensor, it establishes a capacitance to the ground, typically ranging from 30 to 100 pF. This phenomenon can be utilized for...
Capacitive Dimmer switch circuit
The capacitive dimmer switch circuit is illustrated in Figure 9. It operates based on the principle of capacitive reactance with alternating current. When the switch is in the position shown, the normal light bulb operates at maximum brightness. When the...
Capacitive Sensors
For proper operation, the circuit ground must be connected through a small-value, high-voltage-rated capacitor to one side of the mains supply socket. The "Live" side is the right one. This circuit is designed to animate shop windows using a capacitive...
RealView 2.0
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...
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...
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...
