SEE DIY compressor time delay circuit. Protect your compressor when power outage and Electrical fluctuations. Using normal parts and cheap.
The Simple long duration timer circuit using OP-AMP, If build the RC timer only that long time delay we need too many resistors and capacitors may be error [...]
For learn about MOSFET. I recommend Time Delay circuit easy to make and long time and a few parts than normal transistor
The surge protection circuit important! Sometimes, our electrical appliances may damage easily by little high voltage surges. We can protect this problem.
These are many Monostable multivibrator using 555 timer. We use it as timer for control a load, LEDs,driver relay. Which trigger them using a normal switch. [...]
This circuit is based on learning of the discharge and charge of the C. This can be used as a timer circuit and can be applied in the OFF electrical…
This is the simple time delay circuits using JFET. Which it will alarm with a buzzer sound. In circuits have a few parts. And an important component is 2N3819-FET---Small Signal…
