Here is a jacket that uses NeoPixels that let you monitor the status of up to 40 3D printers. As Sallyhall explains, this is being used at Duke’s Innovation Co-Lab Studio.
You are going to need Particle Photon, 40 smart NeoPixels, conductive thread, sewable shield, and a few other components to complete this. More information is available on Instructables. What do you think? Worth a shot?
