The ultrasonic proximity detector circuit PIC12F675 detects the distance installed on the microcontroller as adjustable from about 30 cm to 3 m Ultrasonic Distance measurement is based on measuring the rotating time of the radiating ultrasonic wave reflected from any object. Thanks to the use of the Microchip PIC12F675 microcontroller and integrated hardware functions, the…
Regulator circuits such as LM317, LM350, which are used for many electronic circuit feeding, do not have current adjustment. In this project, current adjustments are provided with a few additions, and the reference voltage is pulled to zero, and a simple cheap laboratory power supply circuit with a voltage between 0.30V and 0.3A current is…

I previously shared a short video with v4 version in Sprint-Layout printed circuit preparation video narration. I made a new video for Sprint Layout 6 and tried to show as many details as possible. General settings, features, single, double and ground plane PCB drawing examples, Gerber import, Image PCB copying, tips and tricks. Sprint Layout…
Circuit diagrams of many welding machines available on the market, even if the brands do not match the model numbers, welding machine service manuals. Some models have the same control, driver floors only IGBT, transformer, etc. It was launched in different models by increasing its power. Welding Machine Schema List AIKEN Weld Ranger 160 MWD160…
Even though regulated circuits over transformerless direct mains voltage are not recommended, they are used in many circuits, products, especially in the lighting industry. In general, simple regulated circuits with serial capacitors and zener are used. This circuit is made of more advanced 2-stage regulated. In this way, high output current is provided. 230v mains…
Method: Salvaging ferrite cores Why The world is full of electronics being unceremoniously discarded. Said electronics contains power supplies. Said power supplies contain a number of magnetics, namely transformers and chokes with ferrite cores, of all sorts of sizes and shapes (well, usually E or EI, but anyway). A computer power supply will have several.…
Since TO − 204 sheath power transistors are used, cooler, pcb assembly etc. a challenging but high quality design. The amplifier has Output short-circuit protection. T22 and T23 take current measurements over 0.47-ohm resistor and take the T11 and T12 to the cut and go to protection. You can increase the protection sensitivity by reducing…
