Ticklish Techs

It has been a long time since my first post about home automation in my new apartment. And now it’s time for a wrap up what’s going on here. First of all: most what is described in that post is implemented and up and running for more then one year now.

So let’s have a look at the basic setup that’s in my closet:

Or as an easy to read schematic:

At the bottom you find the FEZ Cobra board. That’s the µC-board or the heart of everything here.

In the row above a simple 12 V power supply can be found, two cards of output drivers for the relays and a card with multiple purpose: Power regulator, I2C voltage converter, DMX driver.

The blue rows contains 16 relays switching 220 V DC lights within my apartment. This is the only part of my whole installation where the power is more then 12 V. So be careful when touching here.

At the top row four cards with each 8 input ports with optocouplers can be found.

I will describe all parts in futures posts in detail.
