2015/12/24 (R) Christmas Eve 2015

Neither of us slept as well as we would have liked last night.  The outside temperature only dropped into the upper 60’s with high humidity and the interior of the coach stayed a bit warmer than that.  Linda woke up and read from 2:30 to 3:30 AM; at least that’s what she told me this morning as I was unaware of it at the time.  We both got up at 8 AM and enjoyed our first cup of coffee while iPadding and listening to Christmas music CDs.  We bought an apple strudel at Publix last night that appeared to be vegan and had some of it for breakfast with our second cup of coffee.  It wasn’t great strudel, but it was still a treat.  All-in-all it was not a bad way to start Christmas Eve day.

Williston Crossings RV Resort, and many of its residents and temporary guests, have been in the holiday spirit since we arrived here on the 1st of the month.  Red and green laser “starlight” projectors are in widespread use at night and many sites have decorated their street light and/or RV with lights while some have put up more substantial decorations.  Most notable, however, are the golf carts, many of which are decorated for the season.  Most folks here wave as they pass whether driving their car or golf cart, riding a bike, or just walking, but based on our prior experience this is normal so I cannot say that folks are in a friendlier spirit than usual for the holiday.  There is, however, a fair amount of “Merry Christmas” being passed around and I think it reflects the fact that most folks are glad to be here even with the record heat.

I had an unfinished chore list from yesterday but wasn’t really in the humor to work on those items on Christmas Eve and do not intend to work on them tomorrow either.  One of the side gaskets I our entry door window came out again yesterday, however, so I will have to fix that again and do so soon, certainly before we leave for Arcadia.

Linda went for her solo morning walk at 10:15 AM and I settled in to work at my computer.  I was determined to make headway with uploading blog posts but first I wanted to dispatch the article for Bus Conversion Magazine on the installation of the ITR Oasis Combi diesel-fueled hydronic heating system in Butch and Fonda Williams’ MCI MC-9 NJT.

Butch had made a number of good edits that filled in missing details so I incorporated all of them and rewrote a few sentences in my own voice.  I then moved all of the photos for the print version of the article “in line” with the text and changed the format to 2-column.  I even figured out how to get the text to wrap around the vertical photos to get a better idea of how many pages the article will take.  I completed this work around 12:30 PM and uploaded it to the BCM proofreading folder in my Dropbox.  I also updated my article status tracking spreadsheet and uploaded that to the Dropbox.  I moved the files on my computer from the Out-For-Review folder to the Proofreading folder and mirrored that on the NAS.  I then e-mailed BCM publisher Gary Hatt to let him know the article was there and ready for review.

Linda got back from her walk and made sandwiches for lunch with mock deli slices (vegan), Daiya non-dairy cheese slices, and lots of greens.  We ate outside as the temperature in the coach was 89.something degrees F.  She stayed outside in the shade and read but I went back inside to work on blog posts.  I was not really uncomfortable, as I was not exerting myself physically, but knew we would have an uncomfortable night if we did not cool off the coach.  When Linda came back inside we closed up the coach and turned on two of the three air-conditioners.  I worked the rest of the afternoon on my blog, editing and then uploading seven posts covering September 1 through 7.

For dinner we had the leftover pizza from last night’s visit to Satchel’s.  We managed to get six dinner meals out of our three visits which is 25% of our dinners for the first 24 days of December.  At dinner last night we suggested to John that it might be nice to have a special campfire on Christmas Eve.  He liked the idea and said he would check with Bob (the resort manager) and take care of it if he got the green light.  Linda packed some wine and we walked down to the firepit at 6:30 PM.

Long before we got to the firepit we could see there was no fire.  In fact, there wasn’t anyone there.  We noticed golf carts at Jeff and Kathy’s site nearby, including John and Ali’s, so we walked over there.  We found Ali, along with three other folks, but not John.  It turned out that John was ill with some sort of gastrointestinal ailment and there was not going to be a special Christmas Eve fire.  There were enough empty chairs for us to have a seat so we stuck around for a while to chat and enjoy a small glass of wine.

Kathy got a Samsung Galaxy Tab 3 Lite for her grandson Spencer and asked me if I would get it set up for him.  I did this two years ago and agreed to try again.  Spencer is arriving tomorrow afternoon with his family and Kathy was hoping to have the tablet set up so he can use it right away.

I got a pair of text messages from my long-time friend, J. C. Armbruster, wishing me a happy Christmas Eve and inquiring as to our whereabouts.  I did not have my glasses or stylus with me so I deferred replying until we got back to our rig.

When we returned we found a large box sitting on our entry stepstool.  Linda checked the label and it was definitely addressed to us.  The office closed at 1 PM today and there wasn’t anything there for us when Linda checked around noon, so it must have arrived later.  Someone in the office must have figured it was Christmas gifts and brought it to our site, which they do not normally do.  Linda opened it enough to confirm that it was, indeed, gifts from Brendan, Shawna, and Madeline and then set it aside for tomorrow.

I replied to the text message from J. C. (which sounds a little bizarre on Christmas Eve).  I then spent an hour trying to configure the Samsung Galaxy Tab 3 without success.  I thought the problem was Wi-Fi related as the tablet did not have any difficulty connecting to the resort Wi-Fi system and obtaining an IP address but it never opened a browser window where I could enter the username and password to get through the resort’s filter and out to the Internet.

I turned on the guest network on our WiFi Ranger without a password and tried connecting to that as the WFR was already logged in, but it still did not work.  I tried creating a Samsung account but the screen just said “…processing” and the little icon just kept spinning.  I also tried entering Spencer’s Gmail address and password(s) that Kathy gave me but the device could not connect to Google.  It’s possible that the problem was simply an incorrect e-mail address and/or password but the error message I kept getting said the tablet could not establish a connection to the remote server.  That sounded like an Internet access issue to me.

I also tried resetting the device to factory defaults but the instructions for doing that apparently assumed (required?) that the device had already been set up correctly and activated.  I cleaned the screen and packed everything back into the box.  I will return it to Kathy in the morning.  Perhaps John will be feeling better and can get it to work.

When I picked up the screen cleaner it was wet.  It was sitting on the desk under the air intake for the middle air-conditioner which is on the bottom of the cabinet.  I shut that A-C off, moved the electronics and paper that were sitting there, and wiped up the small amount of water.  Apparently the drain line for the drip pan is clogged so I will have to add that to my list of bus chores.

We were tired of listening to the air-conditioning but it was warm in the bedroom so I turned on the third A-C to cool it down.  Before turning in for the night I turned the fan to a slower speed and tried adjusting the thermostat, as it had gotten rather chilly.

 

2014/09/29 (M) Full Converted (Not)

Linda was up at 5:45 AM.  Hey, it’s just a number.  I mean, who needs daylight?  She quietly got dressed and slipped out of the house to drive to the bakery.  This is how it’s going to be on days when she has to be physically present at the facility.  Unless I am away working on the bus.  In that case she probably does not worry about being quiet.

I got up around 7 AM and had a nice breakfast of homemade granola, orange/grapefruit juice, and coffee and then spent some time catching up on blogs that I follow.  Keith showed up around 9:30 AM to cut the grass.  Butch had called last night to ask Linda a question and asked that I call him when I had a chance.  Our company did not leave until after 9 PM last night, which was great, but too late to call Butch back so I called him this morning around 10:30 AM.

Butch had used a stop leak additive product to try to plug a leak in his Aqua-Hot main coolant loop but it did not work.  The Aqua-Hot is a Webasto-based diesel-fired hydronic heating system.  Rather than repair the Aqua-Hot, or replace it with another one, he decided to order an Oasis Combi unit from International Thermal Research.  The Combi has a lower BTU rating than the Aqua-Hot but is smaller, simpler, and uses stainless steel for some of the components.  It should be more than adequate for their bus, which is very well insulated, and give them years of trouble free service.

Butch and Fonda’s Aqua-Hot is a very similar model to ours and I will probably buy it from them as a source of spare parts.  His burner is fully functional, which ours is not at the moment, and the short term fix for our unit may be to just swap the burners.  I can then repair the defective burner at my leisure and have it available to swap back should the replacement ever develop a problem.

As a result of our conversation I decided that I will take our bus to their place tomorrow, leaving around noon and arriving between 4:30 and 5:00 PM.  In preparation for that trip I needed to gather up and organize parts, materials, and documentation for my initial set of projects.  I also needed to do laundry and select clothes for the trip.  I may also need to do some grocery shopping this evening unless Linda already has food in the house that I can take.  Tuesday morning I will have to load clothes and toiletries, hook up the car, check and adjust tire pressures, load computers and other last minute items, and get the bus ready for travel.

My main focus for Wed, Thu, and Fri will be the Aqua-Hot (no burn and leaky exhaust).  If we have time I would also like to finish installing the Zena 24 VDC power generating system and get it operational.  I will return on Friday afternoon/evening in the car as Butch and Fonda have plans for the weekend and I still have lots of things to take care of back at the house.

Keith finished up with the lawn a little before noon.  He will be back at least two more times, once in mid-October and again towards the end of the month.  Whether he cuts the grass in November or calls it quits for the season will depend on the weather between now and then.  His basic grass mowing season is April 1 through October 31 and he has his business insured for that range of dates, but he said he would come back in November if needed.  The grass should be dormant by then, but there may be a few leaves that still need to be mulched.  There could also be a foot of snow on the ground, so it will all depend on the conditions prevailing at the time.  During the mowing season he spends the work week living at their trailer/cabin at Haas Lake RV Park, which maybe 20 miles from our house, but by November 1 he is looking to move himself and his equipment back home to Milan for the winter.  Milan is at least 60 miles from our house, maybe a bit farther.

I spent a little time at my desk and decided to re-install WordPress 4.0 on the SLAARC, FMCA Freethinker, and FMCA Great Lakes Converted Coaches websites.  I re-installed it a couple of days ago on this (our personal) website, but I have not tried creating or editing image galleries since then so I do not know if the broken drag-n-drop feature has magically been repaired or not.  I suspect not, but Linda says I’m a pessimist.

I had a quick bite of lunch and then read a few more blog entries while I waited upstairs for Brandon from Bratcher Electric to show up and convert the whole house generator from propane to natural gas and do the annual maintenance and multi-point inspection.  He arrived at 2:15 PM and was here for about an hour.  I had him show me how to disable the generator as it has to be turned off anytime I want to shut off the power coming into the main distribution panel in the basement.  He did not have the correct length of flexible gas line and will come back on Friday to do the LP to NG conversion.  Besides disconnecting the propane and connecting the natural gas the conversion involves attaching two wires to a pair of corresponding terminals on the gas valve inside the unit and changing a setting in the controller.

While Brandon was working on the generator I started gathering things from the garage that I needed for tomorrow and loading them in the car and the bus.  We already have quite a few things staged to take to the Surplus and Salvage Rally next week, but I will take those things with me when I return to Butch and Fonda’s early next week.

Linda called at 4:35 PM to let me know she was on the way home.  I drained the water out of the fresh water tank on the bus as it had been sitting in there since June.  (Yuck.)  The fresh water hoses needed to be cleaned before I used them so I filled their storage tub half full of softened water and added some bleach.  I coiled them up, hooked the ends together, let them soak for a while, and then wiped them off with clean paper shop towels.  Much better looking, and probably and lot more sanitary.

Linda got home at 5:30 PM, a very quick trip for that time of day.  Butch had called just as she was getting home to let me know that he had spoken to someone who has two RV spots in Quartzite we can rent for a very reasonable price this winter.  Linda and I need to discuss it, and would like a few more details, but that probably makes more sense than trying to boondock our first time out there, especially as we do not yet have solar panel on the roof of our coach.

Linda made a nice green salad and heated up some of the lasagna from yesterday.  Italian bread with garlic “butter” and a glass of the 2009 Egri Merlot completed the meal.  We talked about our respective days, reminiscent of when we both worked outside the home.

After dinner I finished cleaning the fresh water hoses, filled the fresh water tank, and then drained and stored the hoses.  While I did that Linda gathered food items, bedding, and towels and put them aboard the bus.  It will still take me a few hours to get ready to leave tomorrow, but I should not be rushed getting everything done.

Linda heated up some of the apple/pear crisp for dessert after which we sat on the sofa and looked at highway maps on her iPad.  The map app on the iPad said the trip from our house to Quartzite, Arizona was about 2,100 miles and would take “1 day, 9 hours.”  That’s non-stop, of course; i.e., 24 + 9 = 33 driving hours.  That time works out to just under 64 MPH.  I typically drive the bus at 60 to 63 MPH on Interstate highways, but we do all of our trip planning based on 50 MPH.  That usually works out well at taking into account for fuel stops, rest stops, and non-Interstate roads.  This means our travel time will be more like 42 hours.  Our preference is to only travel 200 to 300 miles per day, or 4 to 6 hours a day, so the actual number of travel days will be between 10 and 7.  We like to spend more than one night at each stop, depending on what there is to see and do in the area, so the number of days it will take us to get to Quartzite will 2 to 3 times the number of driving days.  A lot of the details of our trip will be last minute decisions based on weather, but our “plan” is to leave December 1st and arrive in Quartzite by December 21st, more or less.

 

2014/05/06 (T) RESA Redux

While we were in Florida I spent a little time working on an extension of a project I was deeply involved in the couple of years prior to my retirement.  The Michigan Assessment Consortium (MAC), of which I was a founding board member, sponsored the development of a series of modules for educators on how to develop and use “common assessments.”  “Common” in this case meant “shared across multiple classrooms/teachers,” as opposed to other meanings, such as “ordinary” or “numerous.”  The 24 modules were developed as scripted PowerPoint presentations with learning activities and supporting materials.  They were field tested in a workshop setting and revised based on participant feedback and the experience of the presenters.  The modules were then videotaped at Wayne RESA, with each of the development team members narrating the modules on which they were the lead author.  The videotaped modules, along with the PowerPoint files and supporting materials were made available online through MI-StreamNet free of charge.

There has been a continuing interest in this professional development series but recent changes in the rules for continuing education units (CEUs) required that the modules be repackaged in order to qualify.  Wayne RESA made a decision a few years ago to train some staff members in the Lectora software for creating online courses.  Some staff time became available and RESA approached the MAC and suggested the use of Lectora to repackage the assessment modules to meet the new CEU requirements.  One of those requirements was for assessments that validate the learner’s engagement with the content.  The existing modules did not include such assessments so the original authors were contacted to see if they would develop test items for their modules.  That is how I came to spend some time this winter writing test items.

Kathy Dewsbury-White, the President of the MAC, had arranged to meet today with Ken Schramm (Manager of TV & Media Production) and Bill Heldmyer, TV Producer/Director extraordinaire) to discuss the project.  She asked me to come along, and that is how I came to spend the day at Wayne RESA, from which I retired in June 2012.  There was a MAC sponsored video conference at 10 AM so while Kathy attended to that I roamed the halls of my former place of employment to see who was around.  All told I was able to visit briefly with a dozen or more people and with another half dozen a little longer.  When the video conference was over we grabbed lunch with Ken.  When we got back to RESA we worked with Bill in his editing suite on how we wanted certain aspects of the modules to work.  Kathy and I then worked our way back to Brighton through the afternoon rush hour traffic.

I talked to Butch (W9MCI) on the phone in the evening.  He had spoken directly to International Thermal Research about their Oasis brand hydronic heating systems and gotten some pricing.  There is a real possibility that our rebuilt Aqua-Hot hydronic heating unit in our motorcoach may have a coolant leak and that the leak is in the combustion chamber.  The evidence for this is an excessive amount of white smoke when the units fires up, if it fires up.  If so, it cannot be field repaired and we would have to get a rebuilt unit to replace the failed rebuilt unit, or get a new unit.  At this point my inclination would be to get a new unit from a different company, like maybe ITR.  I have a low tolerance for the repeated failure of expensive engineered systems.
