The circuit of a burglar alarm utilizing IC timer 555/556 functions as a security measure to prevent unauthorized entry into a premises. The alarm generates a loud sound when a thin wire connecting resistor R1 with pin 4 of...

Building a signal generator is an essential project for any analog DIY enthusiast. While already possessing a bench signal generator, the intention was to create a compact, battery-powered device for quickly testing new effect designs. An enclosure from a...

This meter circuit utilizes a single integrated circuit (IC) and a minimal number of external components. It displays audio levels using ten light-emitting diodes (LEDs). The input voltage can range from 12V to 20V, with a recommended voltage of...

This circuit utilizes the TLC555CP timer integrated circuit to flash an LED approximately twice per second. This specific 555 timer operates on a voltage of only 3 volts, allowing it to be powered by two 1.5-volt cells. When using...

This regulated power supply can be adjusted from 3 to 25 volts and is current limited to 2 amps as shown, but may be increased to 3 amps or more by selecting a smaller current sense resistor (0.3 ohm)....
