The Wellbrook Loop Antenna and the (much cheaper) PA0RDT Mini-Whip. Being short of cash, I decided to buy a cheap Mini-Whip […][Continue reading]
I’ve been busy the last couple of weeks, learning all the ins and outs of my new Cetus3D 3D-printer. It’s a cheap printer for around $300, but it has linear rails and can give excellent results. Unfortunately, the calibration quality from the factory was terrible, which is unfortunate on such a superb printer. My Y-axis […][Continue reading]
