1st phase home automation completed !

Sunday, November 11th, 2012

I discarded the rf based automation efforts and stuck to xbee in the end. Currently the whole system dployess xbee in mesh and encrypted, no additional micro controller used, just using the XBEE IO’s, its working great.

Now I need to create a wiki and a correct blog for my home automation. Will update soon on how it goes.

HOOOOH: How it all begun

HOOOOH: How it all begun

 
 

It has been a long journey indeed. In January I decided I need to re-visit the reason I have struggled to build my own house for around 12 years now. It has been a painful struggle. But after the house was finished and I moved in, on August 18th 2011, my birthday :-). I had the most happiest and memorable birthday of my entire life.

 
 

I kept busy with continuing house work until November. But after the last labors left me alone with my house. I still found myself in the midst of a hectic life. But somewhere in the back of my mind I kept telling myself, I had run out of excuses, and I needed to start work on my dream project soon.

 
 

Building this home automation isn’t just a hobby or passion, its my dream. Now that my primary responsibilities are done towards my family, it’s time to realize my dream.

 
 

After a long gap of around 15 years, I held a soldering iron again somewhere in January. It was a rush seeing the solder melt, and fumes choke me. I cried, well almost, mostly from the stupid fumes from the stone dried flux 🙂

 
 

But it took me back to my days, when I could solder a radio out of murthy uncle’s electronics shop throwaways. I was excited and wanted to start building my rocket to moon. There I realized I was sitting on an empty bench with nothing more than a soldering iron and a flux dibbi. I had to hit SP road and buy me all those wonderful beautiful instruments, with those blinking lights and Chinese flashy colors. But weekend was still long way and my office schedule won’t let me take a breathing break until then. So instead I sat down and started planning my first version of HOME AUTOMATION hardware. I never got down using the hardware setup because of its some very stupid and silly draw backs. But I am sure; if I spend a weekend on it I can make it usable for this purpose. I am going to post them still, maybe someday someone looking in here might be able to pick them up and finish them. That is may be, if I don’t get to it earlier on some boring long weekend.

 
 

Move on to next post to read more.

555 based AM radio transmitter

Should help me to extend message system of Janeman to the garden areas.

555 based AM radio transmitter – Hack a Day

filed under: radio hacks

Bust out that 555 timer and use it to build your own AM radio transmitter. The circuit that [Rtty21] is using only needs the timer chip, an NPN transistor, three caps, three resistors, and a potentiometer. It generates an amplitude modulation signal around the 600 kHz range which you will be able to pick up with any normal AM radio. From the comments on the article it seems you’ll get around 30-40 feet of range out of the device. We don’t see this as a competitor for the FM spy microphone, but maybe you can use it as a diy baby monitor.
