Remote Control Power Strip

Step 2 The basic idea

The wonderful people at Simerec provide an amazing assortment of IR solutions for different projects. I originally came across their site after reading this insctructable and was pleased to find they already had an example of a power switching application called The Zapper. It controls one socket and is a little pricey. This is a proof of concept of how to use their SIS-7C chip to build your own remote controlled power strip with 6 sockets!

For this project we will be using the Simerec SIS-7C chip which allows up to 7 different logic outputs (of which we will only be using 6) in order to control our relays that will in turn switch on/off power to our sockets. The SIS-7C cannot run on wall current so we will also need to add an internal power supply for the small electronics. The current output from each of the SIS's output pins is sufficient to drive each of our 5V relays so there is no need for any other intermediate switches! YAY less soldering! The SIS-7C also allows a mode for logic switching so there is no need for extra logic flip-flops! YAY again!

Here is a concept design which I sketched out in chalk before starting. It uses output 7 from the SIS-7C to control one socket via a remote. I'm pretty sure the pin-outs are correct but always triple check each connection with the appropriate datasheet before turning on the juice!

Schematic on a black board... I like it.
