Ultrasonic Range Meter
40 KHz Ultrasonic Range Meter How to measure range using frequency? Of course, You need a device called ultrasonic range meter. In this project it uses the ultrasonic frequency of about 40 KHz. The range measurement based on the time which the ultrasonic returns from the measurement object. In order to measure the range to an object, ultrasonic transmitter-receiver system [...]
Dual Power Supply
Dual Power Supply 78-79xx Series Here is a very simple dual power supply circuit. With using 3 terminals voltage regulator, it’s the best and simplest choice for non-critical applications. 3 terminals term is for input, ground, and output. The 3 terminals voltage regulator. Here are 78xx & 79xx IC (integrated circuit) series that can provide up to 1A load current. [...]
12V Switching Power Supply
12V Switching Power Supply Circuit Here is AC DC 12V switching power supply design that uses a transformer as a source of DC voltage. The unregulated power supply is generated through a diode bridge to reach 40 volts via capacitor C2 and C3 components. t provides 12V output at maximum current 10 Ampere. The 12V switching power supply circuit uses [...]
