Digital-ir-transmitter

Gates U1a and U1b are configured as a low-frequency oscillator. The output waveform at pin 11 is nonsymmetrical, with the positive portion of the signal comprising only 20% of the time period. Diode D1, a 1N914 general-purpose unit, along with...

Analog Summing

A request to build an analog summing amplifier, preferably utilizing vacuum tubes to achieve the characteristic tube sound. An analog summing amplifier is a circuit that combines multiple input signals into a single output signal. The use of vacuum tubes in...

Analog De-Glitch Circuit Circuit

Low-frequency signals produced by transducers, measurement equipment, or data loggers often resemble the first waveform in the figure. The circuit operates as a tracking sample-and-hold, where transients are replaced in the output by the stored value of the current signal...

Simple Digital Logic Probe Circuit

The design of the digital logic probe centers around a pair of complementary bipolar transistors, which, in this application, are used as electronic switches. The digital logic probe is a diagnostic tool utilized for testing and analyzing digital circuits. The core...

Homemade Digital CALL-ID English Version

The reason for this project was to facilitate a quick installation for a local friend 10 km away, enabling the start of real-life testing to identify and resolve bugs and problems before releasing it to other users. The software is...

Analog-peak-detector-with-digital-hold

Analog peak detection is achieved by repeatedly measuring the input signal with an A/D converter and comparing the current reading with the previous reading. If the current reading is larger than the previous one, the current reading is stored in...

Double-Sideband Suppressed-Carrier (DSB-SC) Modulator

When a carrier signal is modulated using amplitude modulation, four frequency components are produced. The first component is the modulating signal itself, the second is the carrier frequency, while the last two are the sum and difference of the carrier...

Analog Voltage Camera-Image Tracker

By utilizing a low-cost RS-170 camera and this circuit, a voltage that indicates the position of an object within the camera's field of view is generated. IC2A and IC2B create a valid video gate that keeps IC3 in a reset...
