It’s been a quiet weekend up to now, got my grandson over, last night we had WAY too much to drink with friends so I’ve been hiding away in my office with the soldering iron to recover. The Internet Thermostat is sitting testing 24/7 – I’m determined to leave it for a couple of weeks to make sure it is reliable before actually using it to control heating!

So, having grasped the basics I’m now 90% through my next project. The board you see to your right is an 8-relay controller, capable of switching 8 devices (lights, heaters etc etc) at up to 2Kw each. You see the relay panel at the bottom, microprocessor on the left and Ethernet controller on the right. The primary control is via the Internet, from, say, my iPhone but I’ve added infra-red remote control (the little green thing top left) and tomorrow depending on the weather I plan to add short range radio control also. The idea being that this would be controllable by short range radio but also that the power of the board could be extended to a further up to 8 relays (or more) for those hard to wire places… depending on the reliability of the radio (I know it works as I had a test rig up with two of them chatting to each other – but I don’t yet know how reliable the radio is.

That’s my next job…
