transistor amplifier self bias
The simplest way to bias a transistor amplifier is through a fixed-bias circuit. The supply voltage is connected to the base terminal of the transistor via the R1 current-limiting resistor. The bias resistor value is typically chosen based on the...
transistors Mystery circuit: latching relay control with transitor / capacitor why doesnt it work
A single-coil latching relay is utilized, which can latch and reset with opposite polarities. Testing of the circuit with dual opposite-biased LEDs showed no flickering in either direction, indicating stable charge and discharge behavior. However, there are concerns regarding the...
chip programmer
This project originated from the need to control home heating remotely from work. Utilizing a VPN connection between work and home, a relay controlled by a PC was considered the simplest solution. However, a control unit that could be operated...
