So you work with multiple 3D printers on a daily basis and would like an easier way to keep an eye on their status? Why not build a jacket with LEDs that show the status of each unit. sallyhall has shared a guide that shows you how to do just that.
This jacket has NeoPixels sewn to its back to display the status of 40 3D printers in Duke’s Innovation Co-Lab Studio. Each light displays status in blue, green, or red. You are going to need Particle Photon, sewable shield, conductive thread, and a few other parts to complete this project. More info is available here.
