We have been beavering away on our first product, the network controlled relay board ( need a catchy name really! ). Rob’s wasted no time and has a circuit and draft layout in progress. Here’s a simple block diagram of boards features ..
For the Cortex M3 we have currently selected the LM3S6100, TI provide the StellarisWare Software library which includes a lot of example code and should make it easy enough to get it running. It also has a built-in Ethernet Mac and Phy to save on the external Phy costs.
The 4 output relays will have 2 modes, they will either be volt free contacts allowing you to attach 4 devices and switch power to them on/off. Alternatively they can be set to provide 12v AC out (from the input power supply) to reduce wiring for certain applications, like Robs garden lights.
An IRDA transceiver will let us experiment with turning the board in to a universal remote as well. This could be set up to fire off a pre-set series of commands to your home cinema whilst turning on the motor for your projector screen for example.
Which in turn is controllable via your iPhone/Android, Exciting! If any one out there has any feature suggestions, let us know!
