Digital Roulette with Display circuit
This circuit is a small digital roulette. It consists of an oscillator IC1, a counter IC2, and transistors Q1-7 that drive the common cathode display DSP1. The power supply typically comes from a 9V battery, but it can also be...
Oscillator IIV
When the oscillator is connected to a DC circuit, a DC blocking capacitor should be connected in series with the potentiometer's wiper arm. For finer output control, a 10 kΩ potentiometer can be added.
In this circuit configuration, the oscillator generates...
Code practice oscillator II
Oscillator, operates with 2 to 12 volts DC (optimal performance is achieved at 9 to 12 volts for maximum volume and clear keying). Additionally, R1 can be substituted with a 500K potentiometer, allowing the circuit to sweep across the entire...
Two-tone doorbell circuit
Utilize the 48V (60V) DC feedback electric current supplied by the phone feedback line as the operational energy source for the electronic doorbell, which is highly economical and practical. This document introduces a two-tone doorbell circuit that operates without a...
Double oscillator metal detector
The circuit consists of two oscillators, both working at about 465 kHz. One uses an if transformer and the other uses an inductor (the search coil LI). The oscillators are coupled by a capacitor (10 pF). A beat note (produced...
sound generator
The construction of this complex circuit will yield the pleasure of generating nearly unlimited sound effects. The circuit is capable of producing a variety of sounds, ranging from the heavy chopping of helicopter blades to the delicate chirping of a...
