Alarm Power Supply
This power supply is suitable for a modular burglar alarm but can also serve other applications. It is designed to provide a 12-volt output with a current capacity of up to 1 amp. In case of mains failure, the backup...
electronically designed siren
The circuit was designed to create an electronic siren to produce an alert sound in emergency situations or any circumstances that require its usage. The 4011 is a quad 2-input NAND gate integrated circuit, characterized by minimal voltage supply fluctuations,...
DIY siren project
Since this is a DC circuit, how and where do the positive and negative wires physically connect to the circuit? Where exactly should all the grounds be connected? The schematic indicates the connections to the power source clearly. However, visualizing...
Object motion detector circuit diagram
The core component of the motion detection circuit is the motion detection chip IC1 (KC778B). The signal frequency from the PIR sensor is low, ranging from 0.1Hz to 10Hz, while the bandwidth is quite broad, which the chip will optimize....
IC 2 tones Siren
Double-tone Police sound Single-tone old ambulance sound This circuit is intended for children fun, and can be installed on bicycles, battery powered cars and motorcycles, but also on models and various games and toys. With SW1 positioned as shown in...
Scoobas Solution Sensing Tactic
This document serves multiple purposes, primarily to document the methods employed by a Scooba robot to detect: a) the presence of an acceptable cleaning solution being delivered to its pump, and b) the excess presence of used solution collected off...
Motorcycle anti-theft lock electronic circuit
The circuit operates using an ASIC lock IC, specifically the 5C058. Pins 1 to 6 are connected outside the key switch to the positive power supply, representing six valid key inputs. To unlock, keys A through F must be pressed...
