From the project
An educational electronics project demonstrating the complete hardware design lifecycle. Features a 2-bit binary adder circuit designed in KiCad, fabricated using traditional chemical etching methods, and housed in a custom Fusion 360 3D-printed enclosure.
Complete Electronics Design Lifecycle Schematic Design • Chemical Etching • 3D-Printed Enclosure
A complete electronics design project demonstrating a 2-bit binary adder built from the ground up. This project encompasses schematic design, PCB layout, traditional chemical etching fabrication, and a custom 3D-printed enclosure.
The device accepts two 2-bit binary numbers via toggle switches, calculates the sum using a 4-bit binary adder IC, and displays the decimal result on a 7-segment LED display.
