Weekend Project V

I have been seeing a number of Automation or Internet/Mobile controlled home appliances projects like Lifx or Ninja Blocks which made me wonder ‘how hard is it actually to do such a thing?’ (from the hardware point of view) so for this Weekend Project I got my self some opt-isolated relays and a power strip with the idea of creating a power switch that can be controlled by TTL, this project is really easy but relatively risky as it involves switching 220V AC so some care is needed

anyways here is a simple use case demo

get a set of opto isolated relays get a cheap power strip open up the power strip remove the unnesacerry items and make some room for the relay board to make the relay board fit in the space we can break some plastic parts by applying little force mark the holes for relay create some holes looking good Finally make the connections to relays
