I’d like to control some AC powered devices in my home with my Spark Core.
I see some options:
Sounds simple with the Spark Relay Shield (though 4 relays is overkill). But then I’d need power for the shield, say a wall wart. Then I’d need a box to put it all in.
Use a Powertail (http://www.adafruit.com/product/268) with the Spark. I’d still need power for the Spark, so wall wart again. And where would I put all this in?
Roll my own:
Create a circuit board with a Spark, power for the Spark and 1 relay. Unfortunately a 240V board does not seem a suitable project to learn circuit board design
So all in all you wind up with a clumsy solution and not very cheap to boot. I’d like to see a solution like the Myn3rd (http://www.myn3rd.com) but based on the Spark. The kickstarted MyN3rd hardware looks very nice, but the software does not. Plus I want the hackability of the Spark.
Any ideas? TIA
