“Building a homebrew CPU from scratch takes a large number of logic chips. It is understandable, that implementing registers, program counter, ALU, and other components of the CPU in TTL or CMOS logic does require a substantial amount of chips …
“This project is 7400 series logic ICs based clock. It keeps time solely based on discrete logic ICs and a stable clock source. For the display LEDs, I am using common anode 7 segment displays. This variant is 0.56 …
“After 20+ years of programming, I wanted to get some understanding of the electronics that make my career possible. I had built the basic individual logic gates with transistors on a breadboard, but to build anything meaningful I needed loads …
“The 74HC393 is a widely used ic chip. Its main function is as a binary counter. A binary counter is similar to a Decade counter such as the well known 4017 Johnson counter, but the 74HC393 counter functions slightly differently …
“In this Instructable, I will drive a 28-BYJ-48 step motor, with a UNL2003 darlington array board, sometimes named x113647, without a micro controller. It will have start/stop, forward/backward, and speed control. The motor is a uni-polar …
