Web Controlled Power Outlets - For 3D Printer Workspace

https://www.youtube.com/watch?v=0tXY_7EGgWU This DIY 3D printed power outlet box allows remote control of my 3D printer, lamp, Raspberry Pi, and CAD computer. I created it to avoid leaving devices on all day before or after a print. Now I can turn them off with just one click from any web-enabled device on my wired LAN or remotely over the internet. An Arduino and ethernet shield team up to control four standard 120v 5amp outlets using a computer, tablet, or smartphone. The housing and cover are custom-designed and 3D printed. Even a clear 3D printed cube brings the lights from the Arduino to the front, giving it a unique look that's cooler than a standard power LED. A scrapped phone charger provides the 120V to 5V transformer. A custom-made relay switched circuit board uses NPN transistors. I could have bought a pre-made 4-channel relay board, but I wanted to make mine from scratch. This DIY project lets me remotely control household electronics from any web-enabled device. All files are attached, including STL files, INO Arduino code, and index.htm (to be uploaded to a micro SD card and installed in the ethernet shield).
