| Project prototyping is not just the boring step before the “real” build. In this clip, Max Imagination explains how material choice, waterpr...
| A coil-free dual-conversion superhet SDR built from two NE612 mixers and a few passives. The first mixer down-converts to a 455 kHz IF for s...
| Take a look at a through-hole rebuild of Elektor's low-distortion, 1-kHz analog generator from July 2024. The same proven circuit now fits a...
