2015/10/10 (S) The New Camera

Madeline was awake before 7 AM and coughing loose a bit of nasal/chest congestion.  A little after 7 Linda put on her robe and went to check on her.  I put my robe on too and Linda brought her to bed with us.  She lay quietly between us for a half hour, as dawn gradually illuminated the outside world, but never fell back asleep.  I needed to change position and offered to hold her on the sofa in the living room, which she accepted.  I turned on the fireplace and she climbed up in my lap and snuggled up.  Linda joined us a little while later and the three of us cuddled in the dancing light and warmth of the fire for another 20 minutes.  These are the special moments.

Madeline wanted to see the last part of the Curious George video we watched last night so Linda did video duty while I made a pot of coffee.  By the time the cartoon was done Madeline was awake enough to help make breakfast; vegan pancakes with blueberries incorporated into the batter.  Madeline helped mix all of the ingredients but Linda handled the cooking.  Madeline is only 34 months old after all, and not ready to work with sharp objects or heat.  We had hot real maple syrup and mixed berries on the side with orange juice (not from concentrate).

The whole morning was accomplished in our robes and pajamas and it felt like it was Sunday.  Madeline even got to see a half dozen very large wild turkeys in the street in front of our house.  The cats seem to know when Madeline is seated at the table and often emerge long enough to get a few kibbles and a drink of water.  Madeline got some berry stains on her pajamas so Linda got her undressed to get them out.  Madeline took that as an opportunity to enjoy the freedom of running around in her birthday suit for a few minutes.  You can get away with that when you are not yet three years old.

Everyone got dressed and then took up their stations in the living room.  Linda and Madeline played with Legos and played (with) the organ.  Ms. M and I then played “soccer,” throwing, catching, and kicking a large beach type ball and a small soccer type ball.  Madeline was still a little tired so Linda sat with her while she played an iPad game that involved taking care of a dog.

Yesterday the UPS truck delivered a package from B&H Photo in New York.  Inside was a Sony alpha 99 camera body, specifically an SLT-A99V, which included an infoLithium (Lithium ion) battery and charger, a camera strap, a hot shoe flash adapter, Getting Started instructions, a CD-ROM with software and manuals, and various pieces of paper that included warranties and special offers.  Also in the box was a vertical battery grip (VG-C99AM), five additional infoLithium batteries, a belt-mount battery holder, and two 64 GB SDXC memory cards.

Linda suggested that this was my Christmas and birthday present for the next five years, but the reality is that the old Sony alpha 100 body was an increasingly unsatisfactory camera and needed to be replaced.  I bought the a100 in 2007 or 2008 and have not spent hardly any money on photographic equipment since then.  The a99 has been around for a few years now but is still Sony’s top-of-the-line full-frame (36mm x 24mm) sensor, A-mount lens body, which means it is compatible with all of my old existing A-mount Minolta lenses.  As it turns out, I can also use A-mount lenses designed for smaller sensors, such as the lens that came with the a100.  The a99 detects the lens format and adjusts the use of the sensor accordingly.  The a100 zoom lens, however, was an inexpensive “kit” lens that turned out not to be very sharp, especially around the edges, so it is unlikely that I will ever use it with the a99.

At 24 MP (mega pixels) the a99v is not a state-of-the-art camera by comparison to the newest offerings from Canon and Nikon, or even Sony’s own E-mount product line, but it is double the pixel count of the 12 MP a100, and has many features that the a100 does not have, including much better auto-focus and much better sensitivity to low light.  The maximum effective ISO speed on the a100 is 1600 whereas the a99v is 25600 and can be set even higher if needed.  The a99v also includes a built-in GPS receiver that enables it to geotag images.  It includes a hot shoe flash adapter, as well as a PC flash connection, so I have some hope that I will be able to use my old flash equipment, something I have not been able to do with my much older Sony alpha 100.

The old a100 holds one Lithium ion battery and one Compact Flash card, 4 GB maximum.  It also has an adapter so it can use SD memory cards, but the maximum usable capacity is still 4 GB.  The a99v also holds one Lithium ion battery in the camera body but holds two additional batteries in the vertical grip accessory.  Not only will the vertical grip be handy for shooting in portrait orientation, the two additional batteries should allow for extended shooting time even when using flash.  The body also has two memory card slots both of which can accept SD memory cards up to 64 GB.  Slot one can also accept a Sony Memory Stick Pro Duo.

Digital cameras are sophisticated combinations of mechanical, optical, electronic, and computer technologies.  Compared to film cameras of yesteryear prosumer and professional cameras, both single lens reflex (SLR) and single lens translucent (SLT) like the a99v, are feature-rich devices designed to give photographers complete control of the images that are produced.  That also means they are complicated devices with significant learning curves.  Throw in the fact that cameras like the a99v can shoot HD movies with sound and it takes considerable practice over an extended period of time to really master their use.  But I am retired, and photography is one of my three hobbies, so I have, and will take, the time to learn to use this new camera competently.  Competence in this case means the ability to quickly and intuitively select modes and adjust settings to allow me to capture (create) the images I envision.

Brendan called to see how Madeline was doing and arranged to pick up her up later in the afternoon, after the 3:30 PM start time of the U of M football game.  Unless you are attending the game you do not want to drive in, or anywhere near, Ann Arbor for the four or five hours preceding the opening kickoff.  It’s not a great place to be after the game ends either, especially as regards getting in to a restaurant or pub, unless you specifically want to be part of the pre/post game experience.

Madeline wanted to go outside and swing so we put on our shoes and got her into a light jacket.  She is just learning to pump her feet.  She understands the concept but does not yet having the timing.  When she was done with the swing we collected branches and twigs that were lying in the yard and added them to the burn pile.  We then walked around part of the back yard but her shoes got wet from the grass and she wanted to go back inside.

I checked our apple tree and was surprised to see damage that looked similar to that caused by the Emerald Ash Borer.  It’s possible that deer have been chewing at the bark but whatever the cause there are some very large limbs that are now dead.  What concerned me is that I do not recall them being in that condition the last time I looked.  The tree is very old, very large, and has not been properly pruned for a very long time.  We may end up losing it in the end, which would be a shame, but the time to prune is late winter to very early spring and we have not been here at that time of year the last two seasons.  I have my eye on a portion of the western 2/3rds of our yard, however, as prime real estate for some new trees, including some fruit trees.  But not this year, and probably not next year either.

Madeline was hungry after her backyard adventure.  She had soy yogurt and pistachios for lunch and found the pistachios very much to her liking.  She and Linda watched a Daniel Stripped Tiger cartoon and then she laid down for a nap at 1:30 PM.  I snuck off to my office to check e-mail, install the software that came with my new camera, and start downloading updates for the Linux box.  Completing the installation of the Sony Play Memories Home software required the camera to be connected to the computer, so I installed the two SDXC memory cards and one of the fully charged batteries.  On first power up I had to set the date and time.  I then connected it to the computer with the provided USB cable and completed the software installation.

One of the things the PMH software does is go through the PICTURES folder and catalog all of the images it finds by date and makes them accessible through a calendar view.  The camera also came with the Image Data Converter program for dealing with RAW format image files and Remote Control software that allows the camera to be tethered to a computer and controlled from there.  I will eventually have to figure out if/how Adobe Lightroom and Photoshop deal with Sony RAW files.

I quit working at 3 PM, Linda got Madeline up at 3:30, and Brendan arrived at 3:35.  Madeline had been sleeping pretty soundly and did not wake up easily.  She was initially upset that her mom did not come with her dad to get her and got herself worked up enough that she took quite a while to settle down.  To make matters worse she really wanted to stay another night at our house and was resisting going home even though she wanted to see her mommy.  When you are not yet 3 years of age it’s hard to understand that you cannot have mutually contradictory things at the same time, although I suppose in this case that had Shawna come to the house and stayed overnight Madeline could have had everything she wanted.

Linda got Madeline’s toddler bed deflated and packed for travel and rolled up her sleeping bag.  She and Brendan then gathered up all of the things that had to go back to Ann Arbor.  Madeline does not travel light; the clothes, books, toys, stuffed animals, and other accoutrements filled four carry bags in addition to the bed and sleeping bag.

After Brendan and Madeline left I checked my e-mail and replied to several having to do with my duties as secretary of the FMCA Freethinkers Associate Chapter.  We will be holding our annual meeting by teleconference in the next three to six weeks and I have to update the roster and prepare financial statements.

I transferred the complete User’s Manual for the Sony a99v from the CD-ROM to my laptop, backed it up to the NAS units, and then e-mailed it to my iPad.  I downloaded it to my iPad and spent much of the evening reading it.  We headed off to bed a little after 9 PM.  I tuned into the Create channel on Detroit PBS (WTVS) and watched a series of back-to-back episodes of Cooking with Nick Stellino while I worked on this post.  Nick’s show is charming and he is the poster boy for unapologetic high self-esteem but with no hint of arrogance.  His love of food and passion for cooking is infectious and I enjoy his show.

 

2015/10/08 (R) A Mighty Hose

Linda was up before 6 AM to drive to the bakery ahead of the worst of the morning rush hour traffic.  I was aware of her getting up but fell back asleep.  She is very quiet as she goes about her preparations on such mornings, which I appreciate.

I got up around 8AM, fed the cats, and cleaned their litter tray.  I made half as much coffee as usual and measured out a bowl of granola, probably a little more than usual.  I took my coffee to the living room and turned on the fireplace, expecting to settle in with my cats and work on my iPad, but the iOS 9.0.2 update was available so I started the installation and read the last few pages of Number Theory and Its History by Oystein Ore.  I read from screens more than from paper these days, but I still like to curl up with a printed book.

Jasper used to sit next to me on the sofa in the morning but seems to prefer sleeping on top of one of the back cushions these days.  Juniper, who never used to pay much attention to me, has taken his place.  She has always sought out warm places to curl up but has always preferred Linda’s lap to mine.

My bus project for today was reassembling the plumbing to the two fan-coil heat exchangers that go in the bases under the two desk pedestals.  Yesterday I cut new holes for the supply and return hoses.  My first task was to remove the hoses from the bleeder valves and install barbed plastic plugs in the ends to prevent coolant from coming out.  I then pulled the hoses back and out through the new openings.

I worked on the hose for the right hand (rear most) heat exchanger first.  I positioned the base, routed the hose to the lower fitting, and marked where to cut it.  I put a plastic paint tray liner under the hose before I cut it but more coolant came out than I expected.  I got as much of it in the liner as I could and grabbed a bunch of paper shop towels.  I got the liner outside without spilling any antifreeze and poured the used antifreeze in a one gallon jug that I keep for just this purpose.  I used a funnel that is also reserved for use with antifreeze.

I took the cut off piece of heater hose outside, plugged end down, and set the open end in the tray liner.  We already had a bucket of soapy water in the bus as we had planned on hanging wallpaper yesterday.  I wrung out the sponge and then squeezed some of the soapy water on the floor and cleaned it up with paper shop towels.

With the mess cleaned up I slipped two hose clamps over the end of the hose and worked it onto the lower fitting on the heat exchanger.  If only it had been as easy to do as that description!  The 3/4″ i.d. rubber heater hose did not just “slip” over the 3/4″ o.d. copper pipe even with some residual antifreeze lubricating the inside of the hose and the outside of the pipe.  Indeed, it took considerable and simultaneous pushing and twisting to get the hose on.  It was also a lot harder than I expected to work with the heat exchangers installed in the bases, even without the desk pedestals in place.

I was interrupting my work as needed to take photographs and as I finished up the first hose the camera refused to trigger the shutter.  The LCD screen indicated that the compact flash memory card was full so I went to my office to offload the images from the last few days.  My other CF card was empty so I put that in the camera and set it aside.  I had not backed up my photos to the Network Attached Storage units in quite a while so I decided to take the time to do that.  While I was at it I backed up my blog posts from December of 2014 through July of this year along with several issues of The Gypsy Journal.

As long as I was at my computer I checked my e-mail accounts, logged into RVillage, and logged into my account at B&H Photo.  My new Sony alpha 99 and accessories were on their way from New York and due to be delivered by the end of the day tomorrow.  I am excited to finally be getting a new digital camera with a full frame (35mm) sensor that will work correctly with all of my old Minolta A-mount lenses.

By this point it was lunchtime so I cleaned up (antifreeze is definitely NOT good eats) and scrounged around the kitchen for something tasty but easy to fix.  My “go to” meal is usually roasted red pepper hummus and sourdough pretzel nibblers.  We had a little hummus left, which I finished, but I was still hungry so I made a bowl of popcorn.  I would probably not make a good bachelor.

I went back to the coach and contemplated attaching the other hose to the left heat exchanger.  While I was thinking about it Linda called to let me know she was on her way home.  It was 1 PM so I decided to wait for her to get home to help me install the second hose.  I had some phone calls to make and used the time for that.

I called Karen at Bratcher Electric to schedule the upgrading of our 60 Amp sub-panel in the garage to a 100 Amp main panel.  While I had her on the phone I asked if Mike would itemize the quote.  I also mentioned that they had picked up two or three whole house generator customers through my referrals and perhaps Mike could provide some consideration for that in the pricing.  Next I called Ferman Miller at Countertop Plus in Shipshewana, Indiana to check on the Corian desk top and table.  Ferman answered the phone and said he had called Josh this morning to let him know the pieces were ready for pickup.  I then called Josh to see what his plans were.

We originally agreed that he would pick them up and bring them to our house on his way to visit relatives in the northeast side of the Detroit metropolitan area.  His plans had changed and he won’t be visiting his relatives anytime soon.  He is leaving on Tuesday for a FMCA area rally in the Carolinas and will be gone for a week.  Before he leaves he needs to get something to a customer in Cleveland in addition to getting our stuff to us or deciding that we will have to drive to Shipshewana to get it ourselves.  One option is that we meet him somewhere on Sunday.  Ann Arbor is a possibility but Toledo or Defiance (Ohio) are more likely rendezvous points.

Linda got home around 2 PM and changed into her work clothes.  With Linda’s help I was able to avoid the mess I had with the first hose.  The second hose was even harder to get on than the first one but we managed to do it.  In part because of the arthritis in the joints at the base of my thumbs I do not have as much grip strength as I would like and often need.  The twisting and pushing was hard on my hands and the confines of the base and proximity of crisp wooden edges resulted in lots of small cuts.  This was not something I anticipated in the design and construction of the bases and the installation of the heat exchangers.

I took a break and drove to Northwest Plumbing Supply to see if they had a bleeder valve like the ones in our bus system.  They did not and had never do seen anything like it before.  The showed me a couple of things they did have but I did not buy anything.  I got a call from Brighton Honda that my car was ready for pickup so I headed home to get Linda.  She drove me to the dealership and then went on to Meijer’s for a few grocery items.

I drove to Lowe’s in Howell and was fortunate to find Lars in the plumbing department.  The store was not very busy and he took an interest in showing me various plumbing options that might allow me to replace the bleeder valve with something that would do the same thing while also giving me a way to add antifreeze to the system.  What I ended up with was 3/4″x3/4″X1/2″ copper sweat T and a 1/2″ sweat ball valve with a waste port.

Back home I cleaned some 3/4″ and 1/2″ copper pipe with 120 grit plumbers sandpaper.  I cut two pieces of the 3/4″ pipe about 3″ long and one piece of the 1/2″ pipe about 1-1/2″ long.  I brushed the inside of all the fittings and test fit the pieces.  I then applied flux to all of the surfaces to be soldered, inserted the two 3/4″ stubs into the run fittings, inserted the 1/2″ stud into the bull fitting, and put the ball valve on the other end of the 1/2″ pipe.  I used the lever on the ball valve to mount the assembly in my bench vise.  I removed the waste port cap to protect the neoprene seal and opened the ball valve so as not to trap heat inside.  I then heated the T and the end of the valve and applied the solder.

I figured there had to be an easier way to get heater hose onto the heat exchanger and that Butch was the guy who would know what it was.  I called and he said antifreeze can obviously be used and works fairly well but that a small amount of dish soap would also work as a lubricant and not harm the antifreeze or the Aqua-Hot and its components.  As long as we were on the phone I caught up on their activities.

They were still there at the RV Park in Bouse, Arizona but only until the 15th of this month.  The terms and conditions of their employment as managers of the park had not turned out to be as described during the interview process and they are wrapping up after only a month on the job.  They will move their bus back to Quartzsite and spend at least part of the winter at Joe and Connie’s place where we both spent last winter.  I know it was a big disappointment to them that the situation in Bouse did not work out, but their situation in Q will be familiar, comfortable, and inexpensive, as well as convenient to the Quartzsite Gem and Mineral Club which they joined this past winter.

For dinner Linda made a blend of onions, garlic, mushrooms, and power greens and served it over a baked potato topped with Daiya cheese.  It was very yummy, and the potatoes kept the dish warm all the way to the end.  The weather had turned cloudy through the afternoon and we got the first raindrops during dinner.

I had really hoped to have the hydronic heating system reassembled today so we went back out to bus after dinner to hook up the heater hose that runs between the two heat exchangers.  This was actually two pieces of hose with my homemade bleeder/fill valve half way between the two exchangers.  Even with dish soap the two hoses were very difficult to get onto the heat exchanger fittings and the bleeder/fill stubs, but I got them on.  Linda took pictures while I grunted, groaned, and moaned and I took a few more when I was done.

It was 8:45 PM when we finally quit working, secured the bus, and went inside.  I cleaned my hands as best I could but I could not get all of the black from the rubber hoses to come off.  We sat for a while in the living room and had the last of the frozen chocolate torte that Linda made a couple of weeks ago.  We finally turned in around 10 PM and watched Rick Steve’s Europe, Travel in the Americas, and a couple of cooking shows while I worked on this post.

 

2015/09/23 (W) Autumnal Equinox

We were up at 8 AM, had granola for breakfast, and enjoyed our coffee in the living room by the fireplace.  I like cool mornings.

I spent some time yesterday morning, and again this morning, considering my full-frame DSLR options.  The only 50 MP “35mm” DSLR camera body on the market at this time is the Canon 5Ds/R and there is no indication that Sony plans to introduce a successor to the A99 anytime soon.  The A99 is still available, as is the vertical battery pack/grip and I am at the point where I will probably order one.  It has a 24 MP full-frame CMOS sensor, which is double the resolution of my alpha 100.  More importantly, it will accept all of my old 35mm Minolta A-mount lenses and they will work as designed.

Linda left at 9:40 AM to meet Diane at Kensington Metropark.  I gathered up the laundry, sorted it, and started the first load.  I then settled in at my desk for a while.

I e-mailed Mike (W8XH) to see if he could assist me on Saturday and/or Monday with climbing the tower to do some more antenna work.  I then e-mailed Bill Gerrie to see if he and Karen were in Michigan yet.  I pulled up the initial mockup of the October 2015 issue of Bus Conversion Magazine and proofread my article on replacing the speedometer.  Jorge had done a good job of laying it out.  I e-mailed back four minor corrections, one slightly larger one, and a general comment about the lack of space following periods.  I had an e-mail from Steve Smith (N8AR) with contact information for Yaesu Fusion technical support.

The washing machine beeped so I transferred that load to the dryer and started another one.  I noticed that it was after 11:30 AM so I cleaned the cats’ litter tray, grabbed the garbage from under the kitchen island sink, put it in the trash can, and got it to the street.  Alchin’s normally comes “around noon” but I had a feeling they had already driven by.  They were still in our subdivision, however, and stopped on the way out to empty our can.

I had another cup of coffee and updated this post.  By noon Linda had not called yet let me know she was on her way home so I headed to Lowe’s for a roll of plumber’s sandpaper.  I also picked up the paste we need to hang the new wallpaper.  On the way back to the house I stopped at Teeko’s Coffee and Tea to order some Cafe Europe half-caff blend.  Linda was home when I got back and we had a light lunch.  We have both finally taken off some of the weight we put on this past winter.  Long, hard work days with little or no lunch seem to help.

By the time we got back to work on the bus projects it was 3 PM.  It’s hard to make progress when the workday starts in the afternoon.  Today is the autumnal equinox, so it gets dark much earlier in the evening than it did in late May, June, July and even most of August.  Still, as anxious as I am to get the heat exchangers re-installed we have to deal with the wallpaper in that part of the bus first.  Linda helped me assemble the right desk base, repeating what we did yesterday with the left base.

We installed the metal grates on the air openings (from the inside) and then used doubled-sided tape to affix the plastic mesh to the metal grate.  We put a 1/2″ plywood spacer in the bottom and marked the locations of the mounting bracket holes and the heat exchanger.  We took the exchanger and spacer out, punched the starter holes, and drilled.  Linda cleaned the heat exchanger and used a pair of tweezers to straighten the bent radiator fins, of which there were quite a few.  We cleaned off the two copper pipe stubs that provide the inlet and outlet for the antifreeze and then attached the self-stick 3/8″ X 1/4″ dense foam weather-stripping around the front of the housing.  We mounted the exchanger to the spacer with approximately 1/8″ of the foam weather-stripping beyond the front edge of the spacer.  We put the spacer/exchanger assembly back in the base and I secured it with screws while Linda pulled it into position, compressing the weather-stripping.

I took a few photographs as we worked and took some more of the finished assemblies.  While we were working we got a call from Philip Jarrell of Precision Paving.  Phil was calling to see if we still wanted the French Drain and driveway work done.  He has been busy all summer and even more so coming into fall when folks decide they need stuff done before winter.  He had given us a quote (estimate) back in the spring but could not do the work then because the soil was way too moist.  The property has dried out nicely over the last seven weeks and he wanted to make sure he did the work yet this year if we were still interested.  I told him “yes” and he said he would call “Miss Dig” right away to get the utilities marked and then get started.

I think this annoyed Linda as it will be another significant expenditure, but it’s something I think needs to be done and it is not easy to get a slice of Phil’s time.  (Actually, we have done a lot of difficult work together on the bus this summer and I think she was already annoyed from working with me on the right base.)  Not taking advantage of Phil’s availability would likely mean a two-year delay in getting this work done.

This project is actually a combination of two different projects that happened to make more sense to do at the same than at separate times.  The French drain is intended to dry out the far west end of our property which has standing water in the spring and after heavy rains, and stays moist/soft for the first half of the summer.  There are a lot of trees in that area and we have lost some and are losing others.  The driveway work will give us additional parking for people visiting in their RVs and create the main approach to the location for the bus barn that I hope to eventually build.  The topsoil that Phil pulls out from the driveway will be used to fill in low spots on the west end of the property, further improving the drainage in that area.

Linda returned to stripping wallpaper in the bus while I folded the laundry and put it away.  For dinner we had a salad and more of the soup that Linda made yesterday.  After dinner Linda researched wallpaper installation while I worked at my computer and uploaded eight blog posts from the third week of July.  About the time I finished the last one Brendan called so I went upstairs and Linda put the call on speaker.  He is a couple of weeks into his position at Eastern Michigan University teaching Art History and gave us a status report on how it is going, along with news of how Madeline is doing in her new daycare program University of Michigan.

We watched Dr. Michael Greger’s 2015 nutrition research summary on Linda’s iPad.  This is an annual presentation that he does at the vegan Summerfest in Pennsylvania.  His theme this year was the top health concerns of Americans, based on a major survey that was done by one of the national survey organizations, and what nutrition research has to offer with respect to these.  As we already know, many different diseases, one common answer; whole-food, plant-based, nutrition with no animal products.  We really are what we eat, and Americans are now some of the least healthy people on the planet.  We went to sleep reaffirmed in our dietary choices.
