2014/03/17 (N) St. Patrick’s Day

Leave a reply

By Sunday we were not so much tired as we were relaxed and enjoying low key days with wonderful weather at the RV resort.  The temperature made it into the low 80’s and, even with the windows open and the ceiling vent fans running, it got a bit warmer than that in the coach.  No matter; it was a relatively light day for RVillage website interactions and e-mail and we spent much of the day sitting outside reading.  We can only sit for so long at a time, however, so we went for a few walks and raked some leaves using a rake we borrowed from John next door.

Between 5:50 PM and 7:05 PM we got six e-mails from our whole house generator.  The first three let us know that the utility power had failed and the generator was running and supplying power to the house.  The last three let us know that utility power had been restored, that the generator was no longer supplying power to the house, and finally that the generator had shut down in an orderly fashion and was back in stand-by mode.  Sweet.  With sub-zero winter temperatures giving way to highs in the 40’s and above over the next five weeks we cannot afford to be without heat or a sump pump, both of which depend on electrical power.  Ditto for the AT&T Internet gateway that allows us to remotely monitor and control the whole-house generator and WiFi thermostat.  Technology really is cool when it works.

Williston Crossings RV Resort had a St. Patrick’s Day dinner (a day early) but we did not go, the menu having little-to-nothing we could eat.  The day was feeling a bit summery, so we had veggie burgers with cold green bean kale salad and fresh strawberries for dessert.  At dusk John and Ali decided to have a small campfire at their site next door and we joined them along with neighbors Doug and Paulette (from North Bay, ON) and Jim (“Sonny Fox”).  Glasses of white wine in hand we had our version of a “cocktail party” here at Williston Crossings.  Our bus conversion notwithstanding, we are still “campers” at heart and love to sit around a campfire in the evening.

Rain was forecast for overnight and through the next day, so we closed up the rig before turning in for the night.  The radar showed a heavy band of showers training slightly north of east off the Gulf and slowly drifting south over time towards our part of north central Florida.  We got the first raindrops sometime after midnight and by 4 AM had a full blown thunderstorm in progress.  Awake or asleep we are always aware of, and in close contact with, the weather when we are living in the bus and do not sleep as well as on calmer nights.

St. Patrick’s Day dawned wet and overcast with no discernible sunrise; just a gradual, slight lightening of the sky.  The clouds remained thick and dark all day and the rain was almost continuous until mid-afternoon, with torrential downpours at times, so we hunkered down and worked on computer-based tasks and did some reading.  By late afternoon the rain stopped but a heavy cloud layer continued to move over us from the southwest and the high temperature only reached 67 degrees F.

Soup (or stew) is always a welcome counterpoint to a cool, dreary day.  Linda found a recipe for kale, white bean, and potato stew.  The base was onions, carrots, and celery.  She used black beans instead of white, russet potatoes instead of Yukon Gold, and substituted balsamic vinegar for red wine vinegar.  She cut back on the quantity of water and ended up with a delicious, hearty soup.

We got a short walk in after dinner before the rain resumed around 8:00 PM.  PBS has been fund-raising for what seems like weeks now.  In recognition of St. Patrick’s Day they aired a concert by Celtic Women, followed by a concert by Judy Collins, all of which provided some entertainment for the evening.  Thunderstorms were again forecast for the early morning hours, but Tuesday promised clearer weather.

 

2013_09_28-30 (S,N,M) Gone Fish’in

No, I have not given up my WFPB way of eating, but one of the things I did on Sunday was to run a new network cable from our main Internet gateway (in the kitchen) to my office (in the basement).  I had to pull the cable above a suspended ceiling and then “fish” it up through the floor boards into a wall cavity.  There is a special tool called a “fish tape” that is made for this purpose.  It’s a thin but stiff piece of metal that is coiled up inside a housing with a small hook on the free end.  Because it is relatively stiff, you can push through holes and into wall cavities and other such places until it emerges somewhere, hopefully where you need it to emerge.  I have a fish tape (of course) but I can’t find it (naturally) because the garage/workshop will be the last part of our move to get organized.  So I improvised, and after several false starts ended using a scrap piece of 3-conductor sheathed electrical cable that was long enough, small enough, and stiff enough to get the job done.  But I have gotten way ahead of myself.

As usual, Linda and I went to our South Lyon Area Amateur Radio Club (SLAARC) breakfast on Saturday morning.  Well, almost as usual; we took two cars this time as Linda was headed to Ann Arbor to babysit munchkin Madeline after breakfast, and I was headed in the opposite direction to do ham radio stuff.

Madeline’s domestic servants (our son and his wife) wanted to attend a wedding on Sunday in Madison, Wisconsin and thought the three days required to drive there, celebrate, and drive back might work out better for all involved if their daughter did not make the trip.  They also figured that Madeline would do better in their absence if she was in her own home.  Madeline approved of these plans and gave them the requested 3-day pass.  Although Madeline’s aunt (our daughter) provides child care one day a week, a 3-day stint, over the weekend, in a house without television would mean no college or professional football, and would have been heroic beyond necessity.  This was clearly a job for GRANDMA, who doesn’t have functioning television in her new house anyway, so she wouldn’t miss it.  Besides, when sitting the baby, there’s no time to watch TV (or do much of anything else).

Mike (W8XH) and I had plans to work on the new SLAARC website, but first he had to help Bruce (W8RA) set up his new LP-PAN and integrate it into his ham radio station.  Working on Bruce’s ham shack is no small undertaking.  I’ve never been in the Space Shuttle simulator, but I’ve seen pictures, and sitting at Bruce’s ham station is a pretty good facsimile.  It took Mike a couple of hours, but he got it all working.  We then headed to his QTH to do the website stuff.

Mike and I are building the new SLAARC website using WordPress with the help of fellow SLAARC member Larry (K8UT), who is a bonafide expert in such matters.  A couple of weeks ago we decided to create the new website as a subdomain of the existing website, which is hosted by GoDaddy, and that was an experience in itself.  This would make it very easy, however, to later change some DNS entries and have the original domain name point to the new website.  Larry did the WordPress installation manually rather than using the automatic WordPress installer that most web-hosting companies have available (including GoDaddy).  As a result it has taken longer to get the new site functional, but Mike and I now have a much better understanding of subdomains and an appreciation for some of the complexity that is “under the hood” when using WordPress.  One more call to Larry resulted in some magic on his end, and we were finally up and running.  We then spent several hours installing, activating, and exploring themes.  We haven’t made any final decisions, but we are starting to figure out what questions to ask.  While Mike and I are anxious to move this along, we are not under any external pressure to have it ready by a certain date and want to take our time on the front end.  While it is relatively easy to change WordPress themes even after a website is populated with content, there is a point beyond which that is still going to involve a lot of work.  I like projects, but I don’t like doing projects over (and over, and over …).

I was still in WordPress mode when I got home, so I did some work on our personal website.  I created a tab (main menu item) for “Ham Radio” and created a sub-menu item for “SLAARC”.  These are just placeholders for now, but will eventually have content.  I have also fleshed out the WFPB tab as I start to build out the main menu structure.

Mike lent me an AmpedWireless dual-band WiFi repeater that he wasn’t using and I spent some time Saturday evening and Sunday morning playing with it.  It is a very cool device.  In WiFi repeater mode it will pick up a 2.4GHz and/or a 5.0GHz WiFi network and rebroadcast it.  What’s really cool, however, is that it will pick up a 2.4GHz WiFi network and rebroadcast it as 5.0GHz WiFi network.  I have been looking for a device that will do this for quite some time.  Our iPads and smartphones are all 5.0GHz capable, so using them with a 5.0GHz WiFi signal offloads that traffic from the 2.4GHz network, leaving it for 2.4GHz only devices.  The 5.0GHz band also has a lot more bandwidth than the 2.4GHz band with very few devices using it, so there is less interference and more reliable network connections.  Unfortunately, the device did not work well at our house as it appeared to be in conflict with our WiFi thermostat.

Wireless repeaters, access points, bridges, etc. are all designed so that they can be setup and configured wirelessly through a web-browser.  In order to accomplish this they map a specific URL to a specific IP address in the 192.168.xxx.yyy range.  In this case, 192.168.1.240.  Unfortunately, I think the WiFi thermostat also uses that IP address.  There may be a way to work around this, but I did not have time to pursue that today.  The AmpedWireless device is actually configurable in five different modes.  WiFi repeater is the default, but it can be a Wireless Access Point or a Wireless Bridge, or two other things.

As a result of playing with this device, I think I finally understand the difference between various networking technologies.  A Network Switch (NS) is a device that allows multiple devices to be connected together using network cables, with one cable going back to the router (where the IP addresses are controlled through DHCP).  A Wireless Repeater (WR) is just that; it picks up a WiFi signal and rebroadcasts it (repeats it), usually on the same frequency and channel, but with a different SSID; no cables required.  (The Amped Wireless WiFi Repeater can rebroadcast it on a different frequency and/or channel, very nice.)  A Wireless Access Point (WAP) generates a WiFi network and is connected to the main router through a network cable.  We have a Linksys WAP running now.  A Wireless Bridge (WB) is the mirror image of a WAP.  It allows multiple devices to be connected to it using cables (sounds like it’s a NS) and then communicates using WiFi with a wireless router or WAP.  This allows lots of equipment to be located remotely from the main Internet gateway/router without running a cable between the two locations.

While Linda continued her marathon munchkin duty on Sunday, I worked around the house trying to check things off my “to-do” list faster than they got added.  I didn’t succeed, but I did get a lot done.  My main focus was my office, which had become the place where stuff was getting piled so we could feel like we had put other parts of the house in reasonably good order.  I either needed to get it organized or close it off for the open house.  Some of our fellow hams are coming to the open house and will want to see the ham shack (which is also my office), so closing it off from public view wasn’t really an option.

Monday was odds-n-ends day.  I continued to try to clean up and organize my office and the basement, installed two new door closers on the front screen/storm door, and installed new hardware (tracks) for the pair of bi-fold doors on the kitchen pantry.  It doesn’t sound like much, but it takes all day.  I snagged some replacement toilet flappers from Lowe’s, a nice shelving unit for the bedroom from Staples, and a large quantity of ICE Sparkling Water from Walmart.  (It’s not my favorite place to shop, but Meijer’s doesn’t carry this product.)

Mid-afternoon there was a knock at the door.  It was a representative from a company that is subcontracting with Consumer’s Energy to possibly run a natural gas main down our street.  I walked our property with the guy and explained the rather complicated situation that has led to us having two propane tanks and what they implications of that were for us switching to natural gas.  I went ahead and signed up after making sure we could back out if we decided this really wasn’t what we wanted to do.  As of now, however, we are definitely interested in switching to natural gas.  Consumer’s Energy estimates the equivalent cost for a gallon of propane, which is currently $2.00 + or – $0.40, at $0.77.  At that ratio, our infrastructure payback would be about 3 years.  There is also the added benefit of having a constant supply of fuel without a truck having to come and fill a tank.  Value?  Priceless.

In the late afternoon I had a nice chat with Joe from EZ*Connector.  EZ*Connector is a small company in California that has designed, and manufactures, a keyed, magnetically retained, sealed electrical connector.  It comes in 7 and 14 pin configurations for non-military use and is an ideal solution to the problem of connecting a tow vehicle (bus) to a towed vehicle (car).  Our current setup requires two separate electrical cables with mechanical or friction latches.  The EZ*Connector will provide a much easier and yet superior connection.  They are just now bringing a new 14 conductor cable to market and suggested I wait until early November to order.

Linda called to say she would be home around 7 PM.  I put water on to boil to make angel hair pasta with red sauce, and she picked up a salad on the way home.  She made the sauce last week, and it was fabulous.  (I am not normally a fan of marinara sauce, but this sauce has me rethinking that position.)  A glass of 2009 Egri Merlot to wash it down, and fresh plums for dessert made a fine conclusion to a long day.

 

2013_09_07 (Sat) Wi-Fi & Wall Art

Our day started with the surprise discovery that we did not have our usual domestic hot water.  The HVAC guys were here yesterday working on the hydronic heating system, which includes the water heater, and I had a moment of concern (and annoyance, I admit).  I knew the “boiler” was working because they tested some of the heating loops yesterday before they left.  I also knew it was a zoned system with five loops and more than a dozen valves, so it was possible a valve was left in the wrong position.  Sure enough, the valves for the Florida room (library) loop and the domestic hot water loop were both closed.  I opened them, but unfortunately the hot water tank did not return to its normal temperature in time for either of us to get the hot showers we had planned on taking when we got up.  But we left for our usual Saturday morning ham radio breakfast in South Lyon knowing that we would have our usual hot water when we returned.

There was a good turnout for breakfast and we chatted for a couple of hours.  (BTW: the extended group breakfast chat is one of the hallmarks of retirement, and often occurs on a workday.  It just so happens that Saturdays work best for the members who like to attend the SLAARC breakfast.)

Following breakfast we headed to the recycling center in Howell.  We do not have curbside recycling, so we have to take our recyclables to Recycle Livingston on Wednesdays and Saturdays.  Recycle Livingston runs a very efficient operation and always seems to have lots of workers.  We presume are (mostly) volunteers.  Besides our normal recyclables, we have been accumulating corrugated cardboard as we continue to unpack moving boxes.

When we got back to the house we set up the Wi-Fi enabled main thermostat, a Honeywell Focus Pro TH6320WF that TOMTEK installed yesterday.  This thermostat is located at the start of the main floor hallway and controls the heating loop for the living room / dining room / kitchen zone and the air-conditioning for the whole main floor.  When properly configured it allows us to monitor and control these two parts of the HVAC system.

The TH6320WF was fairly easy to set up, in part because it is a very clever device, and in part because the directions are very clearly written.  When power was first applied it came up in Wi-Fi Setup mode and behaved like a wireless host (router or access point), broadcasting its own name/ SSID .  When I opened my iPad2 and scanned for available Wi-Fi networks it was on the list and I selected it.  I then opened my browser (Safari) and pointed it to the thermostat’s home page.  From there, I activated the thermostat’s wireless client mode and connected it to our primary home wireless network.  At that point the thermostat had an IP address from the AT&T gateway and was able to communicate with a website whose purpose is remote monitoring and control of this type of equipment.  Before that could happen, however, I had to create an account on the website.  The account creation process sent us an e-mail.  Following the instructions in the e-mail we completed the registration and activation process.  We are now able to remotely monitor and control this thermostat using a smartphone, iPad, or computer.

The rest of the afternoon was spent selecting and hanging wall art.  While the hanging part can be tedious, deciding what to hang and where to hang it takes time, judgment, and patience.  It was heavily overcast and starting to rain by the time we got started.  The living room tends to be a bit dark on this kind of day so we decided to hang photographs in the recreation room.  We hung 40 objects in the last three days and have at least two dozen more to install.  Getting the “objects d’art” on the “walls d’house” has dramatically transformed the look and feel of the interior and made a significant dent in the “clutter d’move”.

By 6:00 PM we were tired and a bit hungry.  Since Linda had not had time to prepare our evening meal we decided to try the El Patron Mexican restaurant in Howell.  The vegetarian fajitas worked well for us, they had Dos Equis amber on draft, the wait staff was pleasant and efficient, and our waiter had a subtle sense of humor.  Nuf said.

 

2013_09_06 (Fri) House Systems

Leave a reply

I have often commented here about the “house” systems in our converted coach; the water (fresh and sewage) and electrical (lights, appliances) systems and their components that make a large motorized vehicle behave like a stationary house.  Those components include things that are found in any stationary dwelling (water and sewage pipes, plumbing fixtures, electrical wires, circuit breakers, switches, light fixtures, appliances, etc.), things that are found in some stationary dwellings (sewage tanks, macerator pumps, well pumps, fresh water pressure tanks, reverse osmosis systems, power generators and transfer switches), and things that are not commonly found in stationary homes (yet) (various gauges, batteries, inverters & chargers, power protection devices, solar panels, and even wind turbines.)  RVs do not have geothermal or low-head hydro systems.

Today, however, was about actual house systems, that is to say, systems for our actual (stationary) house.  We have had a “rotten egg” smell in our domestic fresh water system since we bought the house and finally called Adams Well Drilling and Water Treatment, a local Howell-based company, to come out and take a look at our current equipment.  Brian arrived as scheduled at 9 AM and we walked him through the complete fresh water system.  He took some water samples directly from the well (before any filtering, softening, or other treatment).  The good news was that our dissolved iron was at 1.2 ppm (mg/L), which is a treatable level, but above the 0.3 ppm at which iron starts to become a problem in the water.  The less good news came from two directions: 1) that our Water Boss water softener wasn’t doing a very good job and 2) we appeared to have iron bacteria, which a regular water softener doesn’t treat very well (or at all) even with the special “iron out” salt.

We discussed a range of options but Brian’s recommendation, which we accepted, was a new water softener and a “carbon unit”.  The carbon unit is self cleaning using special chlorine crystals, and is very effective in dealing with iron bacteria.  We will also have new sediment and taste filter housing installed as part of the installation.  There may be other issues with the water system in this house, which was built in 1977, but the water treatment equipment was probably due to be replaced regardless of what else we do.  The following website from the Illinois Department of Public Health gives a nice synopsis of iron in drinking water:   http://www.idph.state.il.us/envhealth/factsheets/ironFS.htm .

The other fresh water issue we have, based on the testing that was done as part of the purchase inspection, is Arsenic.  The level that came back from the lab was 34 ppb (ug/L).  The old “safe” level was 50 ppb, but the current “safe” level is 10 ppb.  Zero ppb would be ideal, of course, but is not achievable at a reasonable cost. To further complicate matters, there are two kinds of Arsenic found in well water: Arsenic 5 and Arsenic 3.  The prior water testing did not test for these separately, but the sample Brian took today is going to a private lab that can/will test for each separately.  We were told previously that Arsenic 5 is the more typical and is mostly removed by Reverse Osmosis (RO) but that Arsenic 3 is not removed by RO.  The house has a Culligan RO system installed that supplies water to the refrigerator and a special faucet in the kitchen sink.  It was in the house when we bought it and we decided to continue renting it until we could determine our true needs and consider our options.  Not knowing if we had Arsenic 3 in our water, we purchased a special Arsenic 3 filter from Culligan which installs in the manifold after the RO membrane.  We made a call to Culligan to check on our contract and got a call back from our rep (Jeff) who has been a good guy to work with.  Long term it makes no sense to rent the unit, so we are exploring purchasing it or removing it and having Adams install a similar system.

While Brian was doing his thing, Darryl showed up from DMC HVAC.  Darryl did the HVAC installation for our office/library/garage addition/renovation at the old house and did a great job.  When it comes to contractors I like to use local people when I can but I also like to stick with people we have worked with before.  Darryl is not local to our new place, but he is a known quantity whose work we respect.  Although we have a loop from the hydronic hot water heating system in the Florida room/library, it has some issues.

The major issue is that the supply and return lines run through the ceiling and into the wall which adjoins the garage.  We think this house originally had a detached garage with a concrete patio between the garage and the end of the house.  Sometime later a roof was added connecting the house and the garage and the two open sides were closed in with 16 feet of doorwall and fixed glass panels.  The only practical way to extend the heating systems was to run the pipes overhead.

The other issue is that this space does not have air-conditioning.  (There is a small window mount unit in the garage wall.  Yup, it exhausts heat into the garage.)  We have space in a corner of the garage by this room to install a small forced-air furnace/air-conditioner and get the air to/from the room easily along the garage ceiling.  We would also like a ceiling mounted forced-air furnace in the garage so we can store paints and other things that we want to be able to keep above freezing, or bump the temperature up a bit and have a comfortable place to work.  Darryl installed one of these at our old house, and it was a very nice feature.

In anticipation of this work, we had a second propane tank installed next to the garage when the whole house backup generator was installed back in May.  I told AmeriGas at the time what we planned to do so they did a temporary installation of the tank and ran a line directly to the generator.  One of the thinks Darryl will need to do is mount a permanent pressure regulator on the side of the garage and then run pipe to get the propane over to the two new furnaces.

As Darryl was finishing up, Tom and Tom showed up from TOMTEK HVAC.  TOMTEK is a Howell-based company that we decided to have service our hydronic heating system.  It’s an old Weil-McLain Gold unit with some corroded parts.  It was also filled with water.  When we looked at the house originally the heating loop to the Florida room was shut off.  It turned out that something had failed while the owners were away during the winter and that loop had frozen and ruptured.  They repaired it prior to closing, but I never did understand why the system didn’t have an appropriate anti-freeze in it instead of water.  As of today, it does.

One of the nice things about hydronic heat is that it is easily zoned.  Our system has four zones, each with its own thermostat.  One of those thermostats also controls the air-conditioning for the main floor of the house.  That may seem odd, but it is a consequence of the A/C unit probably being added sometime after the house was built.  As a result, the air handler is in the attic and all of the air ducting is too.  It’s a single system controlled from a single point, and is completely separate from the hydronic heating system except for this one shared thermostat.  It was the failure of this particular thermostat that prompted us to go ahead and contact TOMTEK and have them out to service the system and install four new thermostats.  The one that controls the living/dining rooms and kitchen, as well as the air-conditioning, is a Wi-Fi enabled device that will allow us to monitor the temperature in the hallway, which is the most central point in the house, and control the main heating loop and the air-conditioner remotely if we so desire.  Pretty cool; literally.  The “boiler” needed some additional service for which TOMTEK had to order parts, so they will be back another day to finish up the maintenance on the unit.

Overlapping contractors made for a somewhat intense day.  Fortunately there were two of us available to interact with them, and they all got the attention they needed from us, when they needed it.  As soon as Brian was done I called Adams Well Drilling and Water Treatment and scheduled him to come back on the 11th to install the new water treatment equipment.
