I'm fairly new to electronics, accidentally made an oscillator with this circuit. As showed in the pic, R5 would be an 8 Ohm speaker, or otherwise there could be an LED to show the oscillation. Th...
Для ремонта майнингово оборудования мне нужны хешплаты различных Асиков,но больше всего хешплаты майнера S19pro, gerber файла у меня нет , возможно вам уже приходилось делать подобные заказы?
Hi guys, I need to simulate button presses to a keypad. When one of the buttons are pressed they just go to ground. I have 6 buttons and I want the Arduino to do the same thing as pushing one of the b...
I wanted to try building a driver circuit for a small induction motor, using an ATMega328P (i.e. the micro in the Arduino UNO) to generate a 5 kHz PWM signal which changes duty cycle every period usin...
All I have are a bunch of 8050s and I want to use them as power switches for driving a DC motor. Since the motor will draw more then the maximum amperage rating for an 8050 I was wondering if I could ...
It seems that many of the transistor based designs rely on a variable inductor to fine tune all of the resonant circuits in the system, and I am wondering why variable inductors are chosen over variab...
