Quick tip: Calculating LED Resistor Values

From a question someone posted in Discord. what's a safe bet on how many ohms resistors for 2-pin leds should be This is the basic circuit for an LED, right? LEDs are simply diodes. Diodes are non-linear circuit elements that have a decently high resistance until they reach their Vf

Keyboard Design Part 2 - Schematic Symbols and Footprints

Designing a wholly integrated keyboard PCB from the ground up can be a tough ask. That's why I started by integrating an existing development board into a "carrier" PCB that I designed and ordered. That project can be found here. The concept of using a devkit to build a keyboard

Keyboard Design Part 1 - KiCAD Install

Welcome to the first part in a series on mechanical keyboard design. KiCAD is the hobbyist's greatest weapon in creating bespoke electronics. It is a completely free and open-source electronic design automation (EDA) suite. It is available on most commonly used platforms including Windows, Linux, and macOS. The process of
