DIY Motor Controller Part I: Hardware Design & Bringup Intro Ever since I learned about motors and control systems at university, I have wanted to build a controller from scratch. I enjoy bringing theory to life, with the long term goal of using these controllers in a custom robotics system in the future. Having worked on the hardware side
Stepper Controller V1.0 Project information The main purpose of this project is to get a better understanding on motor controller design. In addition I needed a system to control a stepper with good precision for the Motor Position Sensor (MPS) V1.0 calibration process. Therefore the hardware should not be too complex and
electronics Motor Position Sensor (MPS) Overview For the prototype of my BLDC Motor Controller Board a Motor position Sensor (MPS) for the feedback loop is needed during the development. This is going to be a simple small PCB that can be mounted at the axis of rotation for the motor to measure the position via
electronics DIY Splitkeyboard Building a Custom Split Keyboard: From Concept to PCB Overview This project started since I wanted to try a splitkeyboard for a long time, but since they were pretty expensive in the past. I thought to myself why not use this as an opportunity to learn something new and create
