To use HackSpace Magazine Issue #3, simply start flipping through the pages. Begin with the editor's note to get an overview of the theme. Then, dive into the DIY projects. If you're new to 3D printing or using ESP8266, follow the step - by - step tutorials carefully. When working on the projects, make sure to gather all the necessary materials in advance. Keep the magazine in a dry and clean place to avoid damage. If you spill something on it, gently blot the area with a dry cloth. Don't fold the pages too roughly as it may cause them to tear. Enjoy exploring the world of making and hacking with this issue!
