Headlight Alarm Circuit
The most extreme option would be to supply power through a battery pack. A more plausible source would be the car's battery. However, since the objective of the circuit is to activate the buzzer when the headlights are on, it...
latest touch alarm system circuit
The operating voltage for capacitors C1 and C2 should be raised to 25V if a 12V energy source is used. A general guideline is that the operating voltage of capacitors should be at least double the supplied voltage; for instance,...
Power Buzzer
On average, how often do you need to call family members each day to inform them that dinner is ready or that it's time to leave? Typically, the person being called is in a different room, such as a hobby...
Electronic Locker Guard
Protect your locker or briefcase from theft using this pocket-sized gadget. It emits a loud police siren to attract attention. The circuit utilizes a single integrated circuit (IC).
This circuit is designed to provide a compact and effective security solution for...
Help with a schematic please
A project is underway to construct the CountryHick DI as illustrated on DIYFactory, incorporating a few minor modifications. The final design aims to be a 1U unit with four inputs.
The CountryHick DI (Direct Injection) box is a crucial tool in...
electronic touch switch circuit schematic
The schematic illustrates the design of a circuit that measures the resistance of the skin and transforms it into a functional switching signal.
This circuit typically employs a resistive sensor, often referred to as a skin resistance sensor or galvanic skin...
Touch sensor switch using inverters
This touch sensor switch is designed using inverters (N1, N2) and several common electronic components. In the standby state, a signal is produced by oscillator N3/N4 at the inputs of N1. When the touch sensor is activated, the hand capacitance...
Capacitance operated battery powered light
Touch the plate, and the light will turn on and remain on due to the 47 µF capacitor and the 2MΩ resistor for a duration determined by the timing resistor.
The circuit described involves a touch-sensitive plate that activates a light...
5 Minute Signal
For the past year and a half, a group based in Ann Arbor, Michigan, named GO-Tech has been formed, uniting individuals interested in creating projects using technology, such as hardware, software, metal, and wood. This initiative is referred to as...
