An Advanced SWR meter I built about a month ago. It calculates phase shift so can compute a complex impedance and complex SWR, something most meters cant do. Schematics included.
@freemo I wasn't much of a hardware man. But I picked up the esp8266 and started exploring that for my domotica system. And now I've learnt how to solder properly and built several projects myself. Nice stuff.
@Ronald Soldering is an art form for sure. Too many people are sloppy when they try to solder and break everything and even if they dont it just looks ugly.
