12v Temperature Controlled Soldering Iron

Posted on August 6, 2015 The Engineer

In my shack, 99% of my gear is all 12v powered, which is good for a few reasons: Single Power Supply – This increases efficiency, as I’m only getting the losses of a single supply. Safety – Mains voltages are dangerous, I’m not fond of working on such equipment. Portability

Arduino Based SWR/PWR Meter – The Board

Posted on July 8, 2015February 25, 2017 The Engineer

I recently posted about a small analog SWR/Power meter I got from eBay, and figured it needed some improvement. After some web searching I located a project by ON7EQ, an Arduino sketch to read SWR & RF power from any SWR bridge. The Arduino code is on the original author’s

AD9850 DDS VFO PCB & Schematic Layout

Posted on November 1, 2014November 6, 2014 The Engineer

I recently came across a design for an Arduino controlled AD9850 DDS module, created by AD7C, so I figured I would release my Eagle CAD design for the PCB here. It is a mainly single-sided layout, only a few links on the top side are needed so this is easy

Marine Potable Water Management System

Posted on May 14, 2014 The Engineer

Having two separate water tanks on nb Tanya Louise, with individual pumps, meant that monitoring water levels in tanks & keeping them topped up without emptying & having to reprime pumps every time was a hassle. To this end I have designed & built this device, to monitor water usage
