AC and DC Dummy Load

Posted on Posted in Electronics, Projects

I wanted a variable load for 24VAC that would go up to at least 12VA. Before I would connected power resistors in series but that gets troublesome when you want to change the load with a fine resolution. There are variable power resistors or rheostats but they are big and clumsy and from what I […]

I want to investigate using WiFi instead. After doing a bit or research I found the Electric Imp WiFi modules (Electric Imp) look like they […]
