An old 3D printer becomes a new EMI imager

EMI (electromagnetic interference) can be a real nuisance in sensitive circuits. That might be from one device affecting another, but it can also happen when a circuit on a PCB interferes with another circuit on the same PCB (or another PCB in the same device). Engineering to prevent that entirely is really difficult and it […] The post An old 3D printer becomes a new EMI imager appeared first on Arduino Blog.
