A simple DC to AC Inverter

This article is coming soon (probably winter 2025), I just have to improve my design (my first breadboard version melted after a few minutes) which requires more time and money. Anyway my motivation for building: It is so wonderfully easy to go from Ac to DC. You just use a half or full bridge rectifier. In theory, it's very simple and can be seen on almost every modern device that plugs into the wall (To be fair there's a lot more engineering involved). However, going from DC to AC is another story.

About a year ago, I bought this Amazon mill for about 200$ CAD on a local marketplace. I had absolutely no idea if it worked, furthermore, the electronics were in pieces so a bit of a gamble for sure. In this post, I will explain how I got it in working condition and tell you if this type of used equipment (Amazon/Chinese mill, 3D printers, etc) is worth buying.

In this post, we'll dive deep into the mechanics of rotary encoders and potentiometers and provide some simple code.

While both devices are essential for measuring rotational movement, they have distinct ways of operating. Rotary encoders generate digital signals, capturing both the degree of rotation and its direction – perfect for projects where precision is key. Potentiometers act as variable resistors, offering an analog output that's invaluable for its simplicity.

Introduction

If you're intrigued by large language models (LLMs) but feel overwhelmed by the torrent of new information flooding the internet, you're not alone. New models, white papers, and products come out every day as the field is rapidly evolving. This guide aims to clarify LLMs like ChatGPT, Phind, and others, enough that a first-year computer science student can understand the basics of how this technology works and have some key insights into how they can best take advantage of it.
