Sincere apologies to everyone who has left a comment but has received no reply (yet) – business-as-usual will resume shortly. […]

It was only when I discovered how overly complex it was to get this device going that I resorted to the rather “faffy” solution in my video (just to prove it would all work!). No more faffing this time, though. So how easy […]

You can still see some of the snow behind the shuttering, after the snow melted a few days later. The workshop will be about […]

My latest video shows how easy it is to set up a couple of RS485 modules connected with two wires and an Arduino µController at either end so you can communicate with an outbuilding, shed or workshop, without using radio waves. Even better is that you can connect several RS485 modules to the same two wires, so one for the shed and one for the barn, for example. Did I […]
