    Help with DT Project (includes an inductive charger).

    Hi Everyone, my DT project includes an inductive charger. I would like to build a circuit that when a voltage is received from the inductive charger (9Vdc in ~5Vdc out) one LED blinks then after 10s it remains constant. Then turns off when voltage is stopped. I’m not entirely sure how to go...

    Digital Clock using 74LS192

    Hi people I would like to make a digital clock with HOURS and MINS using 74LS192 IC. Below attached is my schematic diagram for the connection of the circuit. However, the MINS counter keeps counting from 00-59 and resets and does not increase the HOURS counter after each 60mins. Components...

    How do you solve the following dependent circuit problem? I tried to use KVL to get i1, but I got .44, which is the wrong answer.

    Circuit problem: I have the answers to it, but I need to know the process of how to get there.

    Need Help with LED Driver design

    I'm trying to design an LED driver that takes a ground as ON, performs a logical NOT on it, and sends it into an N Channel MOSFET. The MOSFET will give ground to a color channel on an LED strip. LED Strip Driver-schematic.pdf I believe I have taken care of everything, but to be honest, this is...
