Converting from single to dual zone HVAC - Part II

Posted by iostream212 in iostream212's Blog, 06 May 2013 · 267 views

Background In part 1 I had done the research needed in order to do this project. I also acquired some equipment for the install. Now on to the install! Action I hate going up and down into the attic, so the first thing I do is prepare a bucket of tools of everything I can possibly think of needing during the install to minimize the number of trips. O...

3D Printer Build

Posted by TonyNo in TonyNo's Blog, 29 March 2013 · 299 views

I finally decided on a 3D printer design and I'm going with the Prusa i3 . I was going to buy an existing kit, but, found that I could save ~$400 by sourcing everything myself. Let's see if that pans out. :lol:  The i3 is essentially a combination of a Mendel  and a Wallace . Of course, I start down this road and then find a design that I like b...

Pioneer SC-1222K is a winner

Posted by jwilson56 in jwilson56's Now Playing Blog, 09 March 2013 · 358 views

Well the Pioneer SC-1222K came early so I decided to swap it out. My initial thoughts Pros: 1)  The receiver runs cool to the touch even after a few hours of cranked up music and movies 2)  The Class D3  amplifiers are a clear winner for sound quality. My Polk Monitor 70's have never sounded so good. I was always less than impress...

Odds and ends and starting a new driver

Posted by Shinyshoes in If the shoe fits, 15 October 2012 · 746 views

Just a quick update with some little odds and ends I have been cleaning up.

I'm very happy to report that since I "Extended" the antenna in my driveway sensor receiver has been performing flawlessly.  Hopefully I can finally put that issue to bed and move on.

I have also been busy adding some electrical plugs and switches in the garage.  I...

Elk M1 Zone Temperature Sensor protocol decoded

Posted by N4HC in Joe Novosel's Elk Notes, 03 June 2012 · 1243 views
and 1 more...

Through reverse engineering I was able to decode the protocol used to transmit temperature to a main zone input on the Elk M1 control.  This will ONLY work on a main zone and NOT on an input expander.  This is by design on the Elk itself.

So here it is.  Manchester encoded:

· 3 start bits of ‘1’
· 8 data bits –...

New House Journey

Posted by roussell in Roussell's Blog, 25 April 2012 · 4818 views
New House

We're building a new house. We're set to go to the initial plan review this week, I'll be recording my journey here.

The builder is pretty strict on who does the work - they're people. I think it's so they can charge $180 for a 'data drop'. The great thing is that I've been talking with the GC and a few other key people and they're agreed to 'turn...

It's starting to look a little more like a respectable install

Posted by SIMKO in Simko's Blog, 08 March 2012 · 463 views

Now that I was happy that everything was working fine, I organized the wiring some.

Things still left to do:
- Get the M1XEP running off of the VAUX rather than the wall-wart.
- Mount VAUX, SAUX, and speaker terminal strips on a Leviton security bracket above the M1.
- Install Pulseworx UPB

I wanted to put the covers on the Panduit for the picture, but...

Upgraded HVAC 2-Zone system to an RCS Communicating system

Posted by Work2Play in ToddB's Blog, 28 October 2011 · 459 views
HVAC, RCS, Thermostat

For those following along, this is my second automated home.  The last home was a single story ranch house on a raise foundation with easy attic access, prewired for security, and nothing worked when I moved in, so it was easy to get sprinklers, HVAC, doorbell, sprinklers, and everything else up and running with one good day of wire running.

In this house...

Paranoid

Posted by Monk in Monk's Blog, 20 August 2011 · 351 views

After spending thousands on Z-Wave modules we decided to make an effort to protect them. The final straw occurred about 9AM last weekend - 3 rapid-succession power outages happening all within maybe 2 seconds or so. I thought my Z-Wave thermostat was semi-fried - it was allowing me to set the date / time but would not "save" it. Turned out OK...

Slow going

Posted by mustangcoupe in mustangcoupe's Blog, 14 June 2011 · 183 views

So activity here on the sale of our current home has slowed down, so we wait.... Once things pick back up and we lock in a buyer we start to build the new place.  At that point I will add more details here on the blog.

It has been a while, what have I been up to?

Posted by auto_man in auto_man's Blog, 14 May 2011 · 204 views

Well I didn't realize it had been so long since I last posted.  It is amazing how time flies when you are having fun.  Over the last year I have been busy conducting experiments and doing some small projects related to home automation and power saving.  In addition, instead of attempting to build my own power monitor, I went ahead and purchased the...

Updating an Asus 4-in-1 WL330gE with DD-WRT OS

Posted by pete_c in pete_c's Blog - Gigabit Ethernet on the home network, 22 April 2010 · 1747 views

Purchased an Asus WL330gE portable wireless 4-in-1 router last week.  Its a great little traveling combo AP router as is.  

Updating the OS to DD-WRT will provide some more functionality to it.  I currently have 2 Linksys WRT54GL's and 2 wrt-hp-g54's upgraded with DD-WRT's most current OS versions.

Geothermal - Insufficient water power

Posted by beelzerob in Beelzeblog, 04 April 2010 · 380 views

So I guess some background, as I don't think I gave much....

We have a 3200 sq ft house, not counting the unfinished basement, that we want the unit to be able to heat.  We currently have a 4 ton air exchange heat pump, and I'm dis-satisfied with its heating capabilities.  Our duct work is more than sufficient for a new geo furnace, so really...

Installed my first 3-way automated switch

Posted by Sacedog in Sacedog's Home Automation Blog, 01 March 2010 · 312 views

I got around to installing a bunch more UPB switches this weekend, and finally tackeled a 3-way switch.  It was pretty straight forward, and worked the first time out of the chute.

At the Aux switch location, I did not have a neutral, so I wired the neutral to teh ground, which the instructions said was an acceptable alternative.  The way the Aux switch...
