2015/07/23 (R) Wrapping Up Mara

Leave a reply

Mara’s plan was to make this the last full day of her visit.  Our day started without her as we had cinnamon raisin toast, juice, and coffee for breakfast.  I got a call from Jarel with clarifying questions and ideas about the desk and the pull-out pantry.  After a thorough discussion we had better ways to approach a few things.  He also had a better feeling for the estimated cost of the project and I agreed to send him 50% as a deposit.

I typed up a short letter and printed off the graph that Steve made of the return loss for the M-302N V/U lightning arrestor.  I packed the unit for shipping to Morgan Manufacturing and included the letter and graph.  Linda wrote out the check for Jarel and got it in an envelope to mail.  She then went to the library, Post Office, and Humane Society where she donated cat and dog paraphernalia that we had accumulated over the years.

While Linda was gone I worked in the bus for a while and Mara worked on travel preparations.  I started by removing the old 3/4″ plywood floor from the refrigerator alcove.  The original plywood bus floor appeared to mostly be in good condition but I will put a new secondary floor in the alcove to keep the refrigerator legs above the level of the new tile floor.  There are a LOT of wires running along the floor of the alcove at the back wall and I may fashion a cover for them and seal up the holes at either end.

I removed the AC dimmer for the living room lights and the DPDT momentary contact DC switch from the floor-mounted walnut box where they were installed.  The DC switch controlled the passenger side sofa footrest.  I had to remove the wires from both switches to get them out.  The AC dimmer was easy but the DC switch had four different color wires with spade connectors.  I made careful note of which terminal each color went to and then pulled the spade connectors off.  With the switches out I was able to remove the box and its mounting cleats from the floor and wall.  This area will be tiled and the box will not be reused.

Out of curiosity I tested the switch with an Ohm meter to see how the terminals were connected internally.  I also checked the wires with a DC volt meter to see how they were being used.  Two of the wires were +12VDC and DC ground and the other two went to a connector that was originally plugged into the footrest.  The switch applied 12VDC to the two load wires in one position and reversed the polarity in the other position, making the footrest go out or in respectively.

Last year I had removed two blank outlet covers on the walnut panel next to the co-pilot seat so I knew that these two switches were originally installed there and subsequently moved to the floor-mounted box.  I unscrewed the 1/4″ walnut veneered plywood panel from the wall to see what was behind it.  What I found was a LOT of wires and it was not a pretty sight.  I re-installed the two switches in their original locations and re-routed some other wires so they went up over the HVAC chase.

There was still a large bundle of wires running along the floor at the base of the HVAC chase that I needed to re-route but I decided not to mess with those today.  They are connected to four different switches and a doorbell and disconnecting everything was going to require careful attention to detail.  I pondered the refrigerator some more and decided there wasn’t anything else I could do with it for now and that I was done working in the bus for today.

There is too much to do at the moment to just sit around so I decided to install the new garage door opener for the small garage door.  New is relative; it has been sitting in the garage in its original packaging since we moved into the house, supplied by the previous owners.  The old one has not worked correctly since we moved in and the previous owners bought the new one but ran out of time to install it.  It turned out to be rather more complicated than I expected, with very comprehensive assembly and installation instructions.  It also turned out to be a two-person project so Linda worked on it with me.

We were working and Mara had started prepping dinner when a UPS truck showed up with four boxes.  The delivery included:  Mara’s refrigerator vent cover; the Cutco knives and scissors, and; the ZioTek track system for wall-mounting the monitors in the ham shack (2 boxes).  The vent cover was due for delivery today but the knives were not due until tomorrow, so we were really glad to see them as two of them were for Mara.  The monitor mounting system was also due for delivery today but I had temporarily forgotten about it.

Mara was understandably anxious to see if the vent cover fit her base properly.  It was a VentMate and appeared to be identical to the old one.  She climbed up the ladder on the back of her motorhome and I handed parts and tools up to her.  I then climbed up was well.  She removed the old cover and we set the new one in place.  It was a perfect fit!  We put a small amount of putty under each screw head and then ran them down snug and congratulated ourselves on another job completed and well done.

With Linda’s help we put Mara’s kayak back in its custom carrier which fits in the receiver on the back of her motorhome (she does not tow a car).  The carrier was built by a welding shop in Mesa, Arizona to Mara’s specifications and is made from 2″ square tubular steel and powder-coated black.  The carrier holds the kayak diagonally across the back of the motorhome from lower left (driver’s side) to upper right.  The nose of the kayak sits in a pocket near the driver side rear corner of the motorhome and the midpoint is nestled in a much larger cradle.  A strap runs from the nose pocket up to the midpoint on one side and across the kayak to the other side where it is attached to a ratchet and has a hook on the end.  With the hook engaged in a ring the strap is ratcheted tight and the kayak is secure for travel.  Mara runs an anti-theft cable through an eyelet near the nose and attaches a lock for safe keeping.  The tail sticks up higher than the top of the roof-mounted air-conditioner covers but does not extend beyond the passenger side wall.  The tip of the kayak is 13′ 2″ from the ground.

We made good progress on the garage door opener but had to stop at the point where we needed to attach the motor housing to the ceiling as I needed to get some parts (angle iron and lag screws) that did not come with the unit.  The front of the track was attached to the header above the door opening and we left the motor assembly resting on top of a 6 foot stepladder.

While Mara and Linda prepared dinner I unboxed all of the monitor mounting components.  I was curious to see the parts and wanted to make sure everything was there and undamaged, which was the case.

Dinner was Thai vegan spring rolls in rice flour wrappers.  The prep work was in the cutting of lots of veggies (carrots, zucchini, onions, red and yellow peppers, Chinese cabbage, and mushrooms).  Mara made two dipping sauces, one with ginger, hot peppers, and other things and one based on fish sauce (so we passed on that).  Linda selected our bottle of Malvasia Bianco wine from the Heart of the Desert winery in Alamogordo, NM.  It was white, which we thought would go well with the delicate spring rolls, but very sweet with a slightly thick mouthfeel, like a late harvest Riesling or a Sauternes.  Perhaps not the best choice, but we finished the whole bottle anyway.

We chatted for a while after dinner but like most of our evening meals dinner was a drawn out affair with lots of conversation.  Everyone was tired and the women turned in for the night.  I went to my office and answered e-mails from Gary at BCM that I had seen earlier in the day.  I then went to bed and tried to catch up on blog posts for the last few days but could not stay awake long enough to finish them.

 

2015/07/15 (W) Prime Wednesday

Leave a reply

It was brisk when we got up this morning, with the temperature in the upper 40’s (F), light breezes, lower humidity, and clear, blue skies.  When the weather in Michigan is at its best it is near perfect.

After our usual coffee and granola we spent a little time browsing Amazon.com looking at their “Prime Wednesday” sale.  Neither of us are compulsive shoppers or impulse buyers and scrolling through thousands of items on a slow Internet connection looking for something we can’t live without at a price we can’t pass up is not our idea of fun.  I have things I need to order, like the multiple monitor mounting system for the ham shack, but it quickly became obvious that I was not going to find those items for sale as part of Amazon’s special July 15 Prime Sale.

Mara was up and took her garbage to our trash to can and returned to her rig.  Linda then took our garbage out and moved the can to the street.  By 10:30 AM Mara had not yet emerged from her rig, so I went to my basement office and resumed work on the custom desk design for our bus.  I still need to design the pull-out pantry but I finally ordered the Fulterer top/bottom slide mount from Rockler and had it shipped directly to Jarel in Logansport, Indiana.  It is a serious piece of hardware that will support 450 pounds, so it should be more than adequate for the task.

Mara eventually emerged from her rig and the ladies left for 12 Oaks Mall and Mara’s first ever appointment with Renee in the J. C. Penney’s Salon.  They were gone quite a while, tacking on several stops at pet and food stores before returning home.

I received a second quote for a wall-mounted monitor mounting system from AFC Industries.  It included itemized pricing and an offer of a 15% discount but was still way too expensive.  Though more expensive than a desk-mounted pole system I decided I to order the ZioTek wall-mounted monitor mounting system from CyberGuys.  Being wall-mounted it will get my monitors completely off the desks, leaving room for ham radio equipment to slide underneath and all the way to the back edge of the desk (and beyond).  It will also isolate the monitors from the desk so they won’t move if the desks are bumped.  Another bonus is that I can move the desks to get to the cables at the back of the radios without having to move the monitors.

The monitor mounting system is a significant purchase so I wanted to make sure the components would work the way I need them to.  I measured the three monitors that will initially be mounted using the system and then made a scale drawing to see how they would fit.  I added all of the items to the shopping cart and was getting ready to complete the purchase when I noticed that a 5% discount was available if I joined their e-mail club.  I signed up, received an e-mail, and confirmed my intention to join but the 5% discount did not show up in my shopping cart.  I called the 800 number and was told it would take 24 hours for the discount to be available so I cleared all of the items out of the cart and will re-enter them tomorrow.

I finally settled in to my design work but took several breaks to talk to friends on the Novi and South Lyon repeaters.  The Morgan Manufacturing VHF/UHF lightning arrestor was once again degrading my signal to an unusable level/quality so I once again disconnected the antenna and radio coax and joined them together with an N-female to N-female barrel adapter.  Once I did that I was able to transmit and receive to/from both repeaters full-quieting.

I exchanged a couple of e-mail updates with Jarel Beatty, the cabinet maker in Logansport, and finally quit working around 5 PM.  I came upstairs and found that the weBoost cellular booster systems had arrived from Amazon so I unpacked the shipping box and opened them.  I had not realized when we ordered them that they were designed for use in a car with an inside antenna that requires the phone or other cellular device to be 18 – 36 inches away.  That is not very far and it is a fairly small range.  As the name implies, however, it is designed for use while in motion which is what both we and Mara need/want.  I decided to temporarily install one of them in Linda’s car to test it.

Sitting in the driveway in a relatively bad location my phone was in 3G mode with a weak, but usable, signal that hovered around -115 to -118 dBm.  With the booster turned on my phone switched to 4G-LTE and the signal strength improved to anywhere between -103 to -94 dBm.  (The less negative the signal strength in dBm the stronger the signal.)  That may not appear impressive on the surface, and it was certainly not the 50 dBm gain that is claimed for this device, but it was actually a significant improvement.

“dB” is the abbreviation for “decibels” which is a logarithmic scale.  Logarithmic scales are useful for representing quantities that vary over a large range, like cellular signal strengths.  A change of 3 dB represents a factor of two, i.e., a doubling or halving of the quantity.  Thus a change from -118 dBm to -115 dBm (decibels to a millivolt) represents a doubling of the received power.  It is still a weak signal, but it is twice as strong.  Going from -118 to -103 is a change of +15 dBm and is five doublings (-118 to -115 to -112 to -109 to -106 to -103) which is an increase of 2x2x2x2x2 = 32 times.  Continuing from -103 to -94 is another +9 dB change representing three more doublings (-103 to -100 to -97 to -94) for a total gain of 32x2x2x2 = 32×8 = 256 times.  Starting from a signal in the -118 to -127 dBm range that is potentially the difference between useable and not useable.  (BTW:  a change of 10 dB is a factor of 10, so going from -115 dBm to -105 dBm and then to -95 dBm represents an increase of 100 times.)

We had decided at dinner last night that we wanted to go to The Blue Nile restaurant while Mara was here.  The best time to go turned out to be this evening, so Linda made an online reservation for 7:30 PM at the Ann Arbor location (there is also one in Ferndale).  We tested the weBoost Drive 4G-X cellular booster on the drive to/from Ann Arbor and it definitely made a difference in the signal strength we saw on our phones.

It wasn’t until we got part way down Main Street that we realized that today was the opening day of the Ann Arbor Art Fair.  The last place I wanted to be driving, parking, or walking was at the Ann Arbor Art Fair, not because I dislike art (we love art), and not because I dislike art fairs, but because I dislike congested traffic and crowds, which the AAAF has in abundance.  Surprisingly, we were able to park in one of the parking structures a couple of blocks from the restaurant.  After fighting our way through the pedestrian traffic I was even more surprised to find the restaurant essentially empty.  The Blue Nile is slightly outside the portion of Main Street where the AAAF takes place and streets to either side that are closed off to vehicles during the AAAF.  All of the restaurants and the beer/burger joints in and around the AAAF venue were doing a brisk business, especially if they had outside seating (it was a very pleasant evening), but the restaurant was open and the host was very gracious.

The Blue Nile serves Ethiopian cuisine.  Some of the tables are upside down rope baskets with four chairs and two side tables.  We always ask to be seated at one of these because we always order the Vegetarian Feast which is, in fact, vegan.  The Feast comes on a large round tray covered with a layer of Ethiopian sponge bread (made from teff flour) with small piles of the seven different vegetable-based dishes on the menu surrounding a pile of (optional) salad in the center.  Beverages and platters of rolled up sponge bread are placed on the two side tables (we had water and Ethiopian spiced tea).  The meal is eaten by tearing off suitable sized pieces of sponge bread and picking up the eight different selections from the tray.  Before the food was brought to the table we were given hot, moist towels to wash our hands.  Nice touch.

The food was amazing and the experience somewhat more communal than sitting at a standard American table and eating with utensils.  The waitstaff was gracious and attentive and it was a wonderful experience for all three of us.  Mara asked one of the waitstaff to take a picture of the three of us, which they gladly did.  She then uploaded it to her Facebook page along with a brief description of her visit and meal.  One the drive home she already had 12 “likes.”  This is the side of Facebook, and other social media, that is fun.

It was getting dark by the time we got back to the house but we took the time to unload Mara’s kayak from its special mount on the rear of her motorhome that is installed in the tow receiver.  The kayak mounts diagonally from the lower driver side up past the roof on the passenger side and the tip is about 13′ 2″ above the ground.  She was leaving at 6:30 AM the next morning to drive to Cummins Bridgeway to have her main engine and genset serviced and would be traveling south on Hacker Road to Grand River Avenue.  The last time we did this we clipped a branch in the southbound lane on Hacker just north of Bendix Drive not far from Grand River Avenue.  I was concerned that she would catch the same branch and damage her kayak which is why we took it off the rig.

Once the kayak was off the back of her rig and sitting in our yard we said a quick “good night” and all trundled off to bed as 6 AM would come all too soon.  I wrote for a while in bed but was too tired, and full of food, to stay awake.
