The high-voltage power source for portable equipment

Many appliances and devices require high voltage, напри­мер, electronic devices, gas discharge indicator. This makes them difficult to use in portable power supply from the battery pack. Here is a simple description of the step-up voltage converter, allowing the voltage on battery 6V to receive the dc voltage… Continue Reading

single thermostat

The thermostat is designed to control heating water in the tank. the temperature sensor is a thermistor R1 (semiconducting, with a negative temperature dependence). It forms a voltage divider with the resistor R2 Since with increasing temperature the resistance R1 decreases, voltage on R2 varies in direct proportion… Continue Reading

Peripherals for thermostats

The author considers the hardware-level issues of interaction between the controller and peripherals, which can be connected to it in the organization of the local control system. It gives an example of a local control system, implementing a predetermined algorithm using the heating controller and the temperature controller. Currently, the level of… Continue Reading
