TV Antenna Cable Install

by on Jul.08, 2020, under Communications

For the past few years, we have had an external beam TV antenna mounted on a post outside of the cabin.  Pointed at Kingman, roughly 60 miles away, we receive most of the TV channels available from there.  Prior to this, we had DirecTV installed, but gave that up as we recognized that we really didn’t watch many of the channels that were on there.

Each trip to the Ranch would find us crawling on our backs, poking the antenna cable up through a small hole in the floor.  Then when we left for the Valley, we again had to crawl under the cabin to remove the cable.  If we left the cable laying on the ground, it would have been susceptible to cattle stepping on it, and rodents chewing on it.

So on the last trip up in June, we installed some underground PVC conduit from the antenna location to the LittleHouse. After running some RG-6 cable through the conduit, we terminated both ends with Type-F connectors inside an accessible box.  With a barrel connector on each end, we were able to have a complete circuit that could be left in place without the worry of the cable getting damaged.

Remote Monitoring of Solar Charger

by on Sep.25, 2014, under Electrical

Over the labor day weekend, I installed a new add-on for my Midnite Solar Charge Controller.  It is called a Whizbang Jr.

Basically, this allows the charge controller to measure the actual current directly into and out of the battery, without worrying about what loads I might have turned on at any point in time.

This allows the charge controller to make better decisions on when to stop charging on any given day, putting less strain on the batteries.  It also will allow me to more effectively monitor the actual state of charge of the batteries, rather than guessing based on battery voltage.  But that part hasn’t been added to the software, yet.

I haven’t grabbed any photos of my install yet, but here is a generic one that I’ve borrowed from the manufacturer…

Battery Maintenance

by on Aug.12, 2014, under Ranch Maintenance

While waiting for the scrap lumber to burn down, I did battery maintenance.

First, I let the solar panels charge until the charger went into float mode (about 1:00 pm that day).

Then I checked that the water level was above the plates of the battery (it was in all cells).  I had not filled the batteries since May, so I was concerned, but all was well.

I checked the initial voltage on each battery. They were all in the 6.53 – 6.55 range (I wrote them down, but didn’t capture the figures in the snapshot I took to bring back to town).

Next, I put the charger into equalize mode. I ran in that mode for about an hour, but for the last 15 minutes or so, it had clouded up, so wasn’t fully effective.  I’ll have to run another equalize charge next time we come up.

Finally, I let the system go back into float mode, and measured the voltages and specific gravity for each cell.  All were in the good range (1.265 is usually considered 100% charged).

Battery # After Equalization Float Voltage Cell 1 SG Cell 2 SG Cell 3 SG
1 6.55 1.265 1.265 1.265
2 6.54 1.265 1.265 1.265
3 6.56 1.265 1.265 1.265
4 6.56 1.265 1.265 1.265
5 6.52 1.265 1.260 1.260
6 6.56 1.260 1.265 1.265
7 6.56 1.260 1.265 1.260
8 6.53 1.260 1.260 1.260

More Solar Equipment Work

by on Apr.27, 2014, under Electrical

I made it up to the Ranch on the weekend of April 11th. I had four goals on this trip:
1. Install a temperature controlled fan in the solar equipment box
2. Open the place up after winter
3. Replace the water pump for the cabin
4. Collect pictures to support creation of a how-to guide for the Ranch

Solar Installation – Part 3

by on Sep.16, 2013, under Electrical

Once the exterior of the job site boxes was complete, the next step was to bolt them to the porch deck.  I used carraige bolts to minimize the chance of someone removing them from the outside.

Next, I started work on the interior.  The equipment was set in place and moved around until a satisfactory arrangement was found for the solar panel installation.
