Simple 100mA Constant Current Source using Transistor. In this project, we will build a simple transistor constant current source generator using only 4 components. It is a very inexpensive circuit ...

12V clean DC power supply unit. (350mA rated can be used) 100uF / 16V Electrolytic capacitor; Separate Audio signals for mixing. Here PN2222A transistor is used. Different transistor with the same ...

This hobby circuit below was designed for a 12v DC system. But, it could be modified for other voltage as well. It uses an inexpensive photo-transistor as the light detector. An n-channel FET is used ...

When a weaker light beam courses through the second optical line, the ring heats up and swells, interfering with the main beam and switching off the transistor. This switch can flip on and off up ...

Touch sensitive switch circuit Touch Sensitive Switch Circuit. On the other hand, when someone touches plate 2 (which is connected between pin 6 of gate N2 and ground), the RS flip-flop is reset. The ...

Learn how to use diodes, resistors, transistors, relays, and potentiometers to design a circuit that can handle both positive and negative LED polarity. Agree & Join LinkedIn ...

Infineon Technologies has launched an ultra-low resistance high-side switch in a 9.9 x 11.7 x 2.3mm surface-mount package. For automotive use on 12V circuits, the IC is “ISO 26262-ready for supporting ...
