Collaborate Disseminate
Sometimes the projects we write up for Hackaday require their creators to produce pages of technical explanation, while others need only rely on the elegance of the hack itself. The …read more Continue reading Super Simple Scope Shambles Solution
[Voltlog] often looks at interesting test equipment and in the video below he reviews something that isn’t very common in hobby labs: a differential oscilloscope probe. These are usually pretty …read more Continue reading Differential Probe Clocks at 100MHz and $200
[Gerald Musy] wanted to investigate the source of electromagnetic interference (EMI) in his switching power supply design. Stymied by the high cost of EMI probes, he decided to build his own. Lucky for us, he wrote up his results of experimenting with four different designs.
The probes include an unshielded loop, a shielded loop, a ferrite core probe, and an electric field probe. None of these are especially complex to build–the ferrite core one is probably the most involved–you can see from the scope traces that the different probes pick up different information.
Of course, once you identify where the …read more
